1. Introduction This report forms part of the overall design report and documents the schematic design phase of the stormwater drainage design for the Taxiway Zulu and T2T Apron project for the Melbourne Airport.

The purpose of this project is to provide new taxiways, taxi lanes and apron infrastructure to facilitate the expansion of Terminal 2 and thereby accommodate increased growth in passenger numbers and associated aircraft movements. The Taxiway Zulu and T2T Apron project was previously covered by two separate projects in the feasibility design phase, with Jacobs completing the design for the Taxiway Zulu Program and AECOM delivering the T2T Apron component of the works.

This report includes the stormwater drainage design for all areas covered in the proposed master grading as well as existing catchments which flow into the proposed works area. Pipe and grated trench capacities have been calculated and water depths, building freeboard and edge line encroachments have been checked against Melbourne Airport Technical Standards.

Runoff from the proposed network flows into the existing drainage network which discharges to the Arundel Creek 02 and Moonee Ponds Catchments.

2. Schematic Design Development 2.1 Design assumptions

Standards used and referenced during the schematic design stage are as per the Melbourne Airport Technical Standard – MAS-CVL-007 Stormwater Utilities. Refer to Appendix B of the main report (CP14038-AIR-SCH-PM-RP-0002) for full details of design criteria and assumptions.

2.2 Design standards

Standards used and referenced during the schematic design stage are as per the Melbourne Airport Technical Standard – MAS-CVL-007 Stormwater Utilities.

2.3 Key changes from feasibility design phase - Jacobs has been engaged to undertake the design of T2T Apron area as well as Taxiway Zulu project

during the schematic design phase. T2T Apron Feasibility Design by AECOM was supplied to Jacobs for reference. The schematic design philosophy has been developed with the aid of stakeholder meetings and communications with APAM.

- T2T stormwater drainage design has been included in the design scope. As such, Jacobs has taken a holistic approach to design the drainage network where T2T Apron and Taxiway Zulu were analysed as one large drainage network.

- Extrapolated tailwater levels from the Master Drainage Plan model undertaken by Beca Consulting were included in the drainage design at the Schematic phase. It is noted that these are not

- Utilises existing DN1200 pipe south of T2T Apron (to Arundel Creek 02 Catchment) and decreased flow from T2T Apron into Taxiway Zulu system, in turn reducing pipe sizes on Taxiway Zulu system.

- Refinement of the drainage network on Taxiway Zulu.

2.4 Existing drainage network

The existing catchment in the Taxiway Zulu and T2T Apron area is defined by the ridge line formed by Runway 09/27 and Runway 16/34. There is an extensive network of existing drainage pipes and subsoil drainage lines over the proposed project area. The runoff is generally captured by existing grated pits and trenches and largely conveyed south and south west to the Arundel Creek 02 Catchment and the Moonee Ponds Catchment as seen in the extract below from the Master Drainage Plan 2015.

Taxiway Zulu & T2T Aprons - Stormwater Drainage Design Report

CP14038-AIR-SCH-CI-RP-0005

Figure 2-1 Extract from Drainage Master Plan 2015 – Melbourne Airport Existing Drainage Catchments

The Taxiway Zulu and T2T Apron drainage design discharges to Arundel Creek 02 (Outlet 8 in Figure 2-1) and Moonee Ponds Catchment (Outlet 3 in Figure 2-7) described in further detail in the later sections of this report.

The Melbourne Airport Master Drainage Model Report 2013 supplied by Beca Consulting suggests that the existing drainage outfall for the Arundel Creek 02 Catchment and Moonee Ponds Catchments are undersized for existing and proposed developments (refer to Melbourne Airport Master Drainage Model Report prepared by Beca Consulting Consultants dated 15 March 2013, Section 7) for the 10 year and 50 year ARI storm events. While it is outside the scope of this project to analyse downstream upgrade requirements, it is noted that this will affect the hydraulics of the current design. Due to the uncertainty in time frame of the downstream upgrade works, all hydraulic assessments of the Taxiway Zulu and T2T Apron drainage designs have been based on current systems with a view that downstream upgrades will be undertaken to suit. Jacobs understands that further detailed analysis will be carried out by Beca Consulting to incorporate the proposed Taxiway Zulu and T2T Apron works at a future date.

Since the Taxiway Zulu feasibility design phase, an updated Master Drainage Model Report has been provided by Beca Consulting. This report was dated 3 June 2015 and contains information relating to water quality and downstream discharge rates. The network modelling results prepared by Beca Consulting were run for the 10 year and the 100 year critical storm event for the existing drainage network. The network modelling results again indicate that portions of the existing network are undersized. MIKE model results for the 10 and 100 year ARI critical storm event was provided to Jacobs for input of drainage design. However, the critical storm event for the Drainage Master Plan does not coincide with that of this project. Furthermore, the 50 year ARI storm event results were not provided.

During the final stages of schematic design, a catchment layout file was provided by Beca Consulting. This file was an input to the Drainage Master Plan model. A brief assessment was undertaken to confirm catchment assumptions made by Jacobs. However, many discrepancies were found. As such, Jacobs has progressed the stormwater drainage schematic design with catchments deduced from ground contours and inferred from the Drainage Master Plan results.

Taxiway Zulu & T2T Aprons - Stormwater Drainage Design Report

CP14038-AIR-SCH-CI-RP-0005

During discussions with APAM and Beca Consulting throughout the schematic design phase of this project, it has been identified that further information on the master drainage model is required to complete the drainage design of Taxiway Zulu and T2T Apron accurately. Additional information to assist with the detail design has been requested by Jacobs and it is understood that these will be provided prior to commencement of detail design phase. Due to lack of critical information such as the 50 year storm event analysis for the drainage master plan model, Taxiway Zulu and T2T Apron schematic design was progressed with assumptions of tailwater levels at downstream connection points to the existing network. As such, the proposed drainage design at Schematic phase may be less than a 65% design.

During the schematic design phase, it was noted that a number of the existing drainage inverts shown on the Mapbase were illogical; some pits also appear to be missing from the Mapbase. As a result, parts of the drainage network were designed based on assumptions on the existing network. Table 1 below is a summary of locations in question. Jacobs recommends field survey be conducted to confirm existing network information in order for a more accurate detail design and such that APAM has an accurate database of existing infrastructure for future use.

Table 1 Summary of uncertainties in the existing drainage network

Location Issue Screenshot Assumption adopted for Schematic phase

Existing network north of RWY 09/27

Unsure of catchment into this system and whether it is a subsoil system or a stormwater drainage system. Contours do not suggest a catchment for these pipes.

No catchment has been assigned to this existing network in the hydraulic model of this project.

Existing system under proposed market place

Unsure of pipe system flow direction and function. As such, unsure where a connection to this system needs to be provided.

The schematic design has been progressed under the assumption that this network has been rerouted south and discharge via a pit at T23.3. The proposed design provides a connection point at this location.

Pit inverts shown on Mapbase are such that the connecting pipe is at an extremely flat grade (1 in 803)

The inverts shown on Mapbase was used in the hydraulic model, however, it should be noted that this could be affecting the HGL levels in the existing pipes.

Existing pit cover and internal sizes

No information is available on existing pit sizes (both pit cover and internal dimensions). At locations where proposed network connects into existing pits, these will be required in order for an accurate design.

General across project site. The schematic phase design assumes that existing pits have sufficient internal size for proposed connecting pipes.

Existing trench dimensions in the T2T Apron area

During a site visit to the Melbourne Airport, Jacobs discovered trenches which are not shown on the Mapbase as well as some abandoned trenches which are still shown in the Mapbase. As such, Jacobs has attempted, as accurately as possible, to measure the grate opening sizes of trench drains in this area to better assess the need for new drainage in this area. However, trench depths are unknown.

It is assumed that the trenches seen on site have a minimum internal width of 0.3m and internal depth of 0.3m.

Existing pit EX1.5 n grassed area between RWY16/34 and TWY Victor

Pit not on low point (20m south of low point). This could be due to error in Mapbase or error in ground topography information.

Pit location not amended in design, however, it is assumed that the low point coincides with this.

2.5 Proposed drainage

2.5.1 Overview

The Taxiway Zulu and T2T Apron stormwater drainage system has been designed for the ultimate phase catchments. The proposed stormwater drainage design for Taxiway Zulu follows the general philosophy of directing all overland flow to low points in grassed areas. The runoff is then captured by grated pits at these low points. Where possible, the existing network has been retained, however, the proposed works have impacted on a number of existing pits and pipes which requires modification or removal of existing drainage. These have been documented in the schematic design drawings. Catchments associated with existing drainage modifications have been reassigned accordingly to the proposed drainage network such that design criteria as per the Melbourne Airport Technical Standard MAS-CVL-007 Stormwater Utilities are met. Where existing pits are retained in the vicinity of the proposed taxiway or shoulders, it is proposed these are modified to junction pits with Class G covers and their heights adjusted to suit. The proposed catchment areas for the Taxiway Zulu area are shown in Figure 2-2 below.

A box culvert has been designed in the area east of TWY Quebec, this culvert is a temporary runoff conveyance measure until the ultimate TWY Zulu extension is constructed. The culvert has been designed to carry the 10 year ARI flow. During the next phase of design, a ford crossing will be graded into the earthworks model in order to create an overland flow path for larger storm events.

Figure 2-2 Catchment Plan for Taxiway Zulu areas

Page 14: Taxiway Zulu & T2T Apron Project

Taxiway Zulu & T2T Aprons - Stormwater Drainage Design Report

CP14038-AIR-SCH-CI-RP-0005

The proposed stormwater drainage design for T2T Apron area uses a combination of grated trench drains and pits and pipes. Cast in situ rectangular grated trench drains are used to capture surface runoff and separate stands from fuel spill in accordance with NFPA415 requirements. The trench drain design has been coordinated with the refuelling locations and plane parking arrangements provided by Airbiz. The new drainage system has taken into consideration new roof catchment areas in the terminal building and marketplace areas and pipes are sized accordingly. However, downpipe connection points are not within the scope of this project.

The grading of the T2T Apron area is such that the general fall of the ground is towards the south west. As such, runoff flows towards the new T2 Western Pier building’s eastern face and Market Place. An invert 15m from the building edge has been created in accordance with NFPA415.

An existing drainage network in the T2T Apron area has been identified on the Mapbase. Care has been taken to identify where existing drainage can be retained. Where practicable, Jacobs’ design has utilised existing infrastructure and minimised the construction of new drainage under existing and proposed buildings. Existing grated trench capacities were assessed in order to gauge the need for additional runoff collection. During a site visit conducted by Jacobs, it was found that the Mapbase data for trench locations was not up to date in the south east edge of Market Place. Information gathered during the site visit was used instead at this location to better assess the current drainage infrastructure in this area. No additional drainage was found to be required, however, where regrading of the pavement is required, existing grated trenches have been proposed to be replaced.

It has been noted that stand D20 aircraft parking orientation has been proposed to be rotated on the Airbiz design layout. Jacobs does not believe this will significantly alter the current functional arrangement with respect to aircraft parking, refuelling activities and the ability for fuel spills to be captured in existing grated trenches. While it is recognised that the current arrangement may allow fuel spill to partially travel to the adjacent stand (D18) prior to capture in a grated trench, it is assumed the design of the Western Apron (including stands D14/D16/D18/D20) was on the basis of a compliant arrangement in accordance with NFPA415 and MOS139. As such, drainage catchments in this area remain as per existing condition with no additional drainage proposed. It is also assumed that the catchment for this stands D14/D16/D18/D20 have already been taken into account in the Drainage Master Plan and that the tailwater level provided by Beca includes flows generated from this catchment.

The proposed catchment areas and general direction of flow for the T2T Apron area are shown in Figure 2-3 below.

Page 15: Taxiway Zulu & T2T Apron Project

Taxiway Zulu & T2T Aprons - Stormwater Drainage Design Report

CP14038-AIR-SCH-CI-RP-0005

Figure 2-3 Catchment plan for T2T Apron area

A portion of runoff from the T2T Apron discharges into the Taxiway Zulu network via a 900mm diameter pipe. The flow from the T2T Apron to the Taxiway Zulu area via this pipe has been reduced since the feasibility phase in order to optimise the hydraulic performance of the network. Refer to Appendix A of this report for a complete overall catchment plan.

2.5.2 Drainage structures

As part of the schematic design phase of Taxiway Zulu and the T2T Apron, a number of different types of drainage structures are proposed for the system. The sections below give an overview of each of the structures used and the performance parameters assigned to them.

2.5.3 Blockage

Blockage factors have been applied in accordance with Metropolitan Planning Authority (MPA) Engineering Design and Construction Manual, Section 13.19. These are as follows:

Sag grated pits: 50% blockage for minor and major events

General direction of flow

Page 16: Taxiway Zulu & T2T Apron Project

Taxiway Zulu & T2T Aprons - Stormwater Drainage Design Report

CP14038-AIR-SCH-CI-RP-0005

MPA guidelines do not apply a blockage factor to on-grade pits, however, in order to reduce the risk of taxiway and runway flooding, a 20% blockage factor has been applied to all on-grade grated pits.

No blockage has been applied to grated trenches in the T2T Apron area as these are not in close proximity to grass or vegetation and are less exposed to objects which cause blockage. Grates are generally run perpendicular to flow direction and trenches are in long lengths of up to 38m, therefore, blockage is very unlikely to occur.

2.5.4 Grated Pits

Grated pits have been designed at the low points of grassed areas and inverts of V-drains in the Taxiway Zulu area. Capture rates for these pits have been taken from VicRoads Road Design Guidelines Part 7 – Drainage Design manual. In order to minimise disruption to the functionality of the airport during maintenance of pits, grated pits have been located as far away from taxiways and blast protection as possible.

2.5.5 Junction Pits

Junction pits have been used in the proposed drainage network where pipes change direction under pavement areas. They have been structurally designed to support airport loading requirements and all pit covers are Class G in accordance with Melbourne Airport Technical Standard MAS-CVL-007.

2.5.6 Grated trench drains

Cast in situ concrete grated trench drains of 300mm grate width and 500mm grate width have been designed to capture and convey stormwater runoff in the T2T Apron area. Where grated trench drains are within the apron areas, their primary function is also to prevent fuel spill from flowing from one aircraft stand to the next in accordance with NFPA 415. Trenches are designed with a typical longitudinal fall of 1% to provide capacity and avoid siltation. Aircraft stand arrangements supplied by Airbiz has been referenced for the schematic drainage design of the T2T Apron.

Grated trench capture rates have been calculated based on theoretical relationships between geometry of flow cross sections and weir and orifice equations sourced from Hydraulic Engineering Circular 22 of the US Federal Highway Administration, (2nd Edition, 2003).

2.5.7 SPEL flame traps

The T2T Apron drainage arrangement has been coordinated with the refuelling locations and plane parking arrangements provided in the Airbiz Design. All grated trench drains that are likely to convey fuel spills discharge into a flame trap. In accordance with NFPA Standards the trench arrangement is required to prevent flow from a fuel spill spreading from one aircraft stand to another.

The schematic design includes the provision of SPEL Units in place of conventional concrete flame traps. These units act as flame traps as well as providing treatment for hydrocarbon and suspended solids.

A number of key drivers for the inclusion of SPEL Flame traps over the traditional Concrete Flame traps are outlined below:

The concrete flame traps have no proven performance on reductions of additional chemicals, nutrients and solutions found on the airside. The SPEL Class 1 systems are high performers on Hydrocarbons and Suspended solids and also reduce heavy metals, nutrients (TP & TN).

The SPEL Flame Trap series provides a monitoring system that detects when a build-up of oil or sediment has occurred within the unit. This means that the need for inspections of each flame trap is removed. The alarm will function and alert the maintenance teams of a spill / need for maintenance. The Concrete flame trap has no remote monitoring facility.

The inclusion of SPEL Units is subject to a cost benefit analysis and the approval of Melbourne Airport.

Additional advantages for the use of SPEL Flame Traps have been attached as Appendix C. The SPEL Flametrap Detailed Drawings, Specification and Data Sheets prepared by AKS Environmental Solutions are also attached as Appendix C.

2.5.8 Drainage pipe design

2.5.8.1 Minimum cover

Minimum cover to top of pipe is 850mm in grassed area and 1m under pavements.

2.5.8.2 Pipe friction

A Colebrook White friction factor of k=0.6mm has been applied for all pipe hydraulics calculations in accordance with MPA Engineering Design and Construction Manual.

2.5.8.3 Pipe material and size

Drainage pipes have been specified as Reinforced Concrete Pipes, Classification 4, in consideration of aircraft loading and minimum cover depths. Design parameters adopted were aircraft loading – A380, minimum cover – 1000mm, pavement type – concrete (adopted pressure distribution is based on flexible pavement, which is less than that of rigid pavements, so conservative approach). Class 4 RCP has been adopted for construction on previous Melbourne Airport apron and taxi projects, with similar pavement / cover conditions. Minimum pipe size adopted for the proposed drainage network is DN450.

2.5.9 V-drains in grassed areas

Depressions graded in the shape of V-drains have been designed to convey runoff and encourage runoff capture in large grassed areas. Side slopes of V-drain batters have been designed to be flatter than 6:1 for ease of maintenance. The longitudinal grade of V-drains has been dictated by the mastergrading requirements in order to achieve a compliant overall grading design. Where possible, they have a minimum longitudinal grade of 1%.

2.5.9.1 Under drains

Under drains have been proposed for V-drains in grassed areas in accordance with Melbourne Airport Technical Standard MAS-CVL-009. These reduce chances of ponding in grassed areas and hence provide better access for maintenance purposes.

2.8 Discharge

The Rational Method was adopted to calculate the design discharge for a given storm event.

QY = (CYIYA)/360, where:

- QY = design flow (m3/s) for the ARI storm for Y years

- CY = design runoff coefficient for the ARI storm for Y years

- IY = the average intensity of rainfall (mm/h) based on the ARI storm for Y years and time of concentration corresponding to the entire catchment area

- A = catchment area (ha)

2.9 Runoff Coefficient

The 10 year ARI runoff coefficients have been taken from Table 17 of the Runoff Coefficient Table Extracted from the MPA Engineering Design and Construction Manual.

Figure 2-4 Runoff Coefficient Table Extracted from MPA Engineering Design and Construction Manual Table 17

The impervious fraction has been assumed to be 1.0 for the T2T Apron area and calculated on a catchment by catchment basis for Taxiway Zulu. Refer to Appendix A for a graphical representation of the catchment breakup.

2.10 Time of Concentration, Tc

A minimum Tc of six minutes for impervious catchments in the T2T Apron area has been adopted due to the size of the catchment areas.

For catchments larger than 5000m2, the time of concentration has been estimated using the equation as given in ARR Volume 1 equation 5.4 where tc = 0.76A0.38 .

2.11 Hydraulics

The hydraulic analysis of the proposed pit and pipe drainage network was undertaken using the storm analysis module within 12D (Rational Method). Pipe design is based on computation of the hydraulic grade line incorporating realistic assessment of pit head losses (Austroads Part 5A was used as a reference). Part full Colebrook White pipe design with 0.15m freeboard has been adopted for the 18.1% AEP (5 year ARI) event and the 9.5% AEP (10 year ARI) event. The 2.0% AEP (50 year ARI) event and the 1% AEP event have been checked for compliance against Melbourne Airport Technical Standard MAS-CVL-007.

Due to limitations in the software for trench grate hydraulics, trench capacities have been calculated by manual open channel flow calculations using mannings formula.

2.11.2 Modelled Scenarios

The hydraulic analysis of the proposed pipes was undertaken using the storm analysis module within 12D (Rational Method). Pipe design is based on computation of the hydraulic grade line incorporating realistic assessment of pit head losses (Austroads Part 5A was used as a reference). Part full Colebrook White pipe design with 0.15m freeboard has been adopted for the 18.1% AEP (5 year ARI) event and the 9.5% AEP (10 year ARI) event. The 2.0% AEP (50 year ARI) event and the 1% AEP event have been checked for compliance against Melbourne Airport Technical Standard MAS-CVL-007. It is worth noting that the stormwater drainage for Taxiway Zulu and the T2T Apron areas are not independent from each other. They are interlinked at two distinct locations (at pit PR7.3 and T29.6) as shown in Figure 2-5. As such, the drainage network for Taxiway Zulu and T2T Apron has been designed as one network and analysed as a whole.

Figure 2-5 Taxiway Zulu to T2T Apron connection points

It was found that for the all storm events analysed, a number of existing pipes between RWY16/34 and TWY Victor appear to be undersized and pits surcharge. This could be due to inaccurate invert information supplied causing the pipe grades to be flatter than actual, inaccurate pit capture rates causing unrealistic HGL levels or inaccurate ground topography information causing catchments to be overestimated. However, these anomalies do not have a significant effect on the proposed network as the connection point is further downstream.

Tailwater levels in the downstream existing network were supplied by Beca Consulting, due to model results only being available for the 10 year and 100 year ARI storm events, extrapolation of results were undertaken in order to apply them for the 5 year and 50 year ARI storm events. While this is not entirely accurate, a sensitivity analysis adopting ± 100mm tailwater height difference has been done on the proposed network using the supplied tailwater levels at each connection point. Results showed no significant differences in pipe sizing on the proposed network.

2.11.2.1 18.1% AEP (5 year ARI)

The 18.1% AEP (5 year ARI) storm event was analysed to check for ponding in the grassed areas and ensure no ponding occurs at all roads and within 0.3m of all buildings in T2T Apron area. The results of the analysis are attached in Appendix B of this report.

2.11.2.2 9.5% AEP (10 year ARI)

The 9.5% AEP (10 year ARI) storm event was analysed to ensure no ponding occurs on the aprons. The results of the analysis are attached in Appendix B of this report.

2.11.2.3 2.0% AEP (50 year ARI)

In accordance with Melbourne Airport Technical Standard MAS-CVL-007, the proposed drainage network has been checked for the 2.0% AEP (50 year ARI) storm event to ensure no ponding within the runway and taxiway edge lines. This criterion is fully satisfied with the current design, however, during the detail design phase,

further refinements will be carried out on the pipe network with more accurate tailwater levels and information on existing drainage network. The results of the analysis are attached in Appendix B of this report.

2.11.2.4 1.0% AEP (100 year ARI)

The 1.0% AEP (100 year ARI) storm event requirements primarily only applies to terminal buildings and operational buildings and assets. There is no specific requirement to satisfy on this storm event for the Taxiway Zulu area. However, because the network is interconnected, the design has assessed the entire drainage network against 1.0% AEP (100 year ARI) event to ensure flows in the Taxiway Zulu area does not have a negative impact on the T2T Apron drainage network. The results of the analysis are attached in Appendix B of this report.

2.12 Arundel Creek 02 Catchment

The proposed network discharges into the Arundel Creek 02 Catchment via pits EX19.1, EX13.1 and EX16.1 as seen in Figure 2-6 below.

Figure 2-6 Areas discharging into Arundel Creek 02 Catchment

The proposed drainage network has been designed up to pit PR1.2, pipe joining PR1.2 and EX19.1 is an existing pipe inserted in the model for completeness and the ability to apply tailwater level at the correct location according to the Master Drainage Plan model. Hydraulic analysis shows that pipes downstream of PR19.1 are undersized. The analysis of the downstream pipe upgrades is outside of this project scope, however, it is recommended that these be resolved prior to construction works on Taxiway Zulu commencing.

Tailwater levels at EX13.1 and EX16.1 were extrapolated from the Drainage Master Plan model, advice from Beca Consulting is that these tailwater levels generated by the existing catchment only. Tailwater affects caused by the inflow at PR1.2 have not been considered for these connection points as it is unknown at this point what upgrade works will be carried out downstream.

2.13 Moonee Ponds Catchment

As see in Figure 2-7 below, the Taxiway Zulu drainage network discharges to the Moonee Ponds Catchment via pits EX7.1A and open channel downstream of culvert C1.1.

Figure 2-7 Areas discharging into Moonee Ponds Catchment

Tailwater level extrapolated from Drainage Master Plan model has been applied at pit EX7.1A. Hydraulic modelling suggests that for the 50 year event, localised ponding up to 0.8m deep within grassed areas occurs at PR5.3 and PR5.2. In accordance with Melbourne Airport Technical Standard MAS-CVL-007, the extent of ponding is limited to grassed areas only and does not encroach onto the edges of adjacent taxiways (minimum 300mm away from taxiway). However, upsizing the existing pipes downstream will reduce the extent and depth of ponding and further reduce risk of impacts on level of service for the airport.

3. Design Limitations and Risks - Due to lack of information on tailwater for the correct storm event and a number of uncertainties in the

Drainage Master Plan, Jacobs schematic stormwater drainage was not able to progress to a 65% completed design. Assumptions made in order to progress the design during this phase are subject to change in the detail design phase.

- A large portion of Jacobs design has been based on information extracted from the Drainage Master Plan. Uncertainties and risks in the Drainage Master Plan model and report are carried through to the Taxiway Zulu and T2T Apron design. Please refer to Drainage Master Plan reports (dated 15 March 2013 and 3 June 2015) prepared by Beca Consulting for details of all assumptions and uncertainties. Jacobs strongly suggests all uncertainties in the Drainage Master Plan be reviewed and resolved before proceeding to the detail design of Taxiway Zulu and T2T Apron project. This will produce a more accurate and refined stormwater drainage design for the project.

- Assumed information for the existing drainage network (catchments and tailwater levels as well as the pit and pipe locations) described in earlier sections of this report poses a risk to the accuracy of the schematic design. Jacobs has taken a conservative approach to design the proposed network to its best ability, however, the network is subject to change when further information is available at the detail design phase.

- Design software used for hydraulic analysis was 12D, this is a common software for drainage design. However, due to limitations of 12D software, catchments are not able to be applied evenly across the full length of grated trenches. Furthermore, grated trenches could only be modelled as a constant depth (i.e does not increase in depth when graded independently of the apron). A conservative approach was taken where the total trench catchment for each trench run was applied at the upstream end of the trench. Trenches were modelled as 300mm wide x 300 deep rectangular boxes in order to give an indication of the HGL and how the flow affects the network.

Trench grate capture and capacity were then manually calculated using rational method to ensure all runoff is captured and any bypass would be collected by a downstream pit or trench grate. Jacobs has taken a conservative approach to ensure pipes downstream of trenches are sized accordingly to satisfy Melbourne Airport standards.

- Grated trenches have been designed with a drop before entering the SPEL unit. This drop is to accommodate the “floating slab” above the unit for load protection as well as the size of the pipe entering the unit. In most cases, this drop is more than 1m from finished surface level to the invert of the drop.

Trench grates have not been widened at this dropped section as Jacobs assumes that the maintenance for the section of pipe entering the unit can be performed from the SPEL unit side. Hence there would be no requirement for a person to enter via the trench.

- As the terminal building and Market Place designs are still in progress, roof drainage including downpipe locations are not known at this stage. Roof catchments have been accounted for as per available Airbiz layout, however, the drainage network adjacent to buildings is subject to change as further information on building design becomes available.

4. Outstanding Matters to be addressed at Detail Design Phase - Accurante tailwater levels for the correct storm events to be applied to the network in order to

complete a more accurate design.

- Uncertainties in the existing drainage network described in Section 2.2 to be resolved.

- Site inspection by designer to be carried out to better understand existing conditions and issues

- A more in depth and integrated analysis of trench grates in the T2T Apron area.

- Details on T2T Apron area regarding SPEL units and connections to be resolved.

- Refinement on the drainage network.

- Additional survey required to extend to current downstream connection points. For this phase, connection levels are based on MapBase Data where survey was unavailable.

- Assessment of the cost-benefit of inclusion of SPEL Firetraps over the use of traditional concrete flame traps.

- Further safety in design details for proposed pits (including pit access, confined space, custom dimensions and lockable covers where required) will be added to drawings for compliance with Melbourne Airport standards (currently in draft form). These will be done via consultation with Melbourne Airport as the standards document progresses.

ITEMS FOR CONSIDERATION

TRADITIONAL FLAME TRAP SPEL FLAME TRAP

Cons

truc

tion

Concrete is Porous – This means that hydrocarbon can leach through the structure of the concrete if it isn’t sealed internally by something like an epoxy coating. Many cases have resulted in contaminated ground water and soil

Non-porous – This means that hydrocarbon will not leach through the structure, this will never pose the risk of contaminating the surrounding ground

Cast In-situ – This allows for much greater error margins by the contractor, this process is also subject to weather conditions and delays much more than a single tank installation

Prefabricated - One Piece, pretested, prefabricated is how SPEL Operates, This means that installation is much quicker resulting in the apron works being completed quicker. This also mitigates risk of ground movement pulling sections of the structure apart.

Temperature Resilience – Concrete is subject to thermal shock, this is outlined in the infamous failure of the concrete interceptor in Lake Macquarie that caused a major spill of oil. This was due to an oil spill that caught fire and resulted in the imploding of a concrete interceptor.

Temperature Resilience – Fibreglass is resilient to high temperatures. This means that if there was a fire for a prolonged period of time the fibreglass would not implode, distort or fail. This has been proven in use on Airport Fire Training Facilities where burning accelerant enters the unit and it snuffs the product on a regular basis.

Chemical Resistance – Concrete is subject to chemical attack found in these applications.

Chemical Resistance – Fibreglass is highly chemical resilient, this allows installation within acid sulphate ground conditions without attack. If there is a chemical spill on the apron this will also be an advantage.

Inspections – The Concrete flame trap that is currently used within the aviation industry has no remote monitoring facility. This system has to be inspected at least quarterly or when an incident is reported.

Inspections – The SPEL Flame Trap series comes with a standard SPEL SET2000 monitoring system, this is an intrinsically safe, online monitoring system that detects when a build-up of oil or sediment has occurred within the unit. For Melbourne Airport this means that the need of inspections for each flame trap are removed. As the SET2000 seamlessly integrates into a BMS system through its volt free outputs, the alarm will function and alert the maintenance teams of a spill / need for maintenance. This is a large cost

Page 67: Taxiway Zulu & T2T Apron Project

saving, removes risk of inspection on aprons and removes need for routine closure of the apron.

Manhole Covers – Melbourne Airport has advised AKS that the Class G manhole covers included with most concrete flame traps are large and require many parts to be removed to inspect and maintain. This creates an issue to remove and is an OHS risk.

Manhole Covers –With this in mind AKS manufactures these systems with either one or two access covers for ease of removal and to limit the OHS risk associated.

Cleaning the system – The Concrete flametraps require complete cleanout, this is costly as the Airport is being Charged per litre for eduction, it also requires refilling with water so it can function as a flame trap

Cleaning the system – The SPEL Flame Trap has an easy clean operating system, Hydrocarbon is primarily contained within the first chamber, this is easily removed with a vacuum truck. Oil and Sediment is removed without the need of removing all water from within the system, being a flame trap, you do not have to refill the system to bring it back online.

Proven Treatment Performance – Concrete flame traps have no proven hydrocarbon or sediment reductions, this means that if treatment is required a large end of line treatment device is required in addition to the flame traps.

Proven Treatment Performance – The SPEL Class 1 Flame Trap series have been utilised in airport and the aviation section for many years. This is due to our performance based systems (The Puraceptor and Stormceptor) conforming to the most stringent standard that Australia owns, the Airport Aviation Act 1997. This Flame Trap system operates with the same internals and treatment principles

Scouring – The concrete systems have been proven to scour captured pollutant out of the system when high flows occur, this is an environmental risk and could be the cause of an incident downstream.

Scouring – Limited Scouring during high flow events, this means that when a spill is potentially most likely, in a storm, the system will be totally reliable to contain hydrocarbon and snuff flames.

Additional Treatment Performance – The concrete interceptors and flame traps have no proven performance on reductions of additional chemicals, nutrients and solutions found on the airside.

Additional Treatment Performance – The SPEL Class 1 systems are high performers on Hydrocarbons and Suspended solids, however they are also reduce heavy metals, nutrients (TP & TN) and can be retrofitted with our Osorb Coalescer to help remove firefighting foam, glycol and much more.
