1. Important information
Item Summary
Further
Information
How much water can
the scheme supply?
The scheme is designed to supply 8,600 ML of water each
year over a 120‐day delivery period on which a summer
irrigation season is based. Water is sourced from winter
flows in the St Patricks River catchment.
Section 2
How can I access supply
from the scheme?
Supply from the irrigation district is accessed through
water entitlements. If you do not hold water entitlements,
you may obtain them through water trading or purchasing
them from Tasmanian Irrigation. Short term supply may
also be accessed from Tasmanian Irrigation through ‘spot
purchases’.
Sections 2, 5 & 6
What are water
entitlements?
Water entitlements are either irrigation rights or delivery
rights. Irrigation rights confer entitlements to have an
allocation of water made available for delivery during
each irrigation season. Delivery rights confer entitlements
to a share of the capacity of the scheme to deliver water
within a zone during the irrigation season.
Section 5
What is the reliability
of the irrigation rights?
Irrigation rights in the irrigation district are warranted to
95 per cent average annual reliability on the basis of the
conditions applying at the time reliability was assessed
and on the basis that the scheme continues to operate as
it was originally designed. The warranty does not cover
reductions to reliability arising from climate changes or
other natural causes.
Section 5
What is the term of
water entitlements?
The term of water entitlements is set to match the term
of the water licence issued under the Water Management
Act 1999 (“WMA”) which will underpin the irrigation
district’s supply. The term of water licences are 40‐years
with provisions for the renewal of water licences set out
in the WMA.
Section 5
Are there any eligibility
requirements to
holding water
entitlements?
Tasmanian Irrigation may refuse to issue water
entitlements, or approve a transfer of water entitlements,
on the basis of credit worthiness. Aside from this, there
are no specific limitations on who may hold water
entitlements.
Section 6
Do water entitlements
provide ownership over
infrastructure?
The infrastructure of the irrigation district is owned by
Tasmanian Irrigation on behalf of the Tasmanian
Government. Water entitlements provide rights to a
supply of water from the irrigation district.
Section 5
Are there costs
associated with holding
water entitlements?
Water entitlement holders are required to pay annual
water charges made up of fixed charges levied on water
entitlement holdings and variable charges levied on water
supplied.
Section 7
Tasmanian Irrigation Pty Ltd Page 2 of 14
Item Summary
Further
Information
Do I have to pay
charges if I don’t use
water?
Fixed charges are payable on water entitlement holdings
regardless of whether water is supplied. However,
variable charges are only payable on water that is actually
supplied.
Section 7
Is GST payable on
water charges?
The supply of water is not currently subject to GST. Should
the GST treatment of water change, GST may be collected
in the future.
Section 7
Are water entitlements
tradable?
Water entitlements can be held by anyone and are
tradable within the irrigation district on a temporary or
permanent basis. The extent of the tradability of water
within the irrigation district is based on the zone
nomination of delivery rights.
Section 6
Why does the scheme
have zones?
Zones arise because of variations in pipeline diameters
and other factors that limit the capacity of the scheme to
deliver water to different parts of the irrigation district.
Sections 5 & 6
Is anything else
required to use water?
In addition to holding water entitlements, to take water
from the scheme you will require a property outlet, a
connection agreement and farm water access plan.
Sections 9 & 10
What is a connection
agreement?
A connection agreement provides the link between water
entitlements and land by specifying the location at and
terms under which water can be taken from the scheme.
Section 9
What is a Farm Water
Access Plan?
A Farm Water Access Plan is a management tool that
identifies and manages environmental risks associated
with the application of water. Its purpose is to
demonstrate that the use of water is sustainable and
complies with Australian and Tasmanian Government
requirements.

2. Scheme overview
Project Summary
The Scottsdale Irrigation Scheme (SIS) is based on a 9,300 ML dam on Camden Rivulet, 18 km south
of Scottsdale in north‐east Tasmania, which would deliver 8,600 ML a year (before transmission
losses). Water will be distributed via a 57‐km underground pipeline network and three local
waterways. The scheme incorporates a mini‐hydro power station which will provide benefits to
irrigators through a lower pumping charge for water supplied during the summer irrigation period
and a sharing of the gross revenue stream from the generation of energy which will reduce annual
fixed charges for irrigators.
Project Description
This scheme will require a 9,300 ML dam to be filled from winter flows from the Camden Rivulet,
which are surplus to environmental and water licence requirements. A two‐way pipeline from the
dam to a pump station located on the St Patricks River will enable supplementary filling of the dam
using surplus winter flows. This will meet Tasmanian Irrigation’s objective of 95 per cent average
reliability of supply.
During the summer irrigation season, water from the dam will be released via the two‐way pipeline
to the St Patricks River pump station. That will pump water over a 50‐metre rise before descending
300 meters to a 2,000 KW mini‐hydro power station located immediately above the existing
Headquarters Road Dam.
Water will be discharged from the mini‐hydro station into Headquarters Road Dam, which will act
as a balancing storage and header tank. From Headquarters Road Dam water will be supplied
irrigators at Scottsdale, Springfield and Waterhouse via a combination of 50 km of underground
pipeline and three natural watercourses.
The district has a highly productive agricultural base with significant potential to grow and diversify,
offsetting and reversing recent economic declines. Approximately two thirds of the water from the
scheme will be applied to pasture based enterprises (dairying, livestock finishing) with a third to be
used for poppies, potatoes and fresh vegetable production.
The project will be an important driver of economic growth in north‐east Tasmania, with direct
benefits flowing to the larger population centres of Scottsdale and Bridport and also to the rural
communities in Springfield, Nabowla and Waterhouse. Increased expenditure by irrigators will also
benefit contractors, agricultural suppliers, business service providers and retail businesses in the
local district.
For reference, a map illustrating the infrastructure of the irrigation district and the water delivery
zones may be found at the end of this document.

3. Legislative environment
In Australia, water is managed by each state and territory in accordance with the Inter‐
governmental Agreement on a National Water Initiative. In Tasmania, water is governed by the
Water Management Act 1999 (“WMA”).
Under the WMA all water resources in Tasmania are vested in the Crown. The Minister for Primary
Industries and Water may grant rights to take water under a system of water licences. Water
licences are currently administered by the Department of Primary Industries, Parks, Water and
Environment (“DPIPWE”).
Where an irrigation district is established, the rights arising under a water licence (or an agreement
deriving from a water licence) may be broken into individual shares and issued as irrigation rights.
Irrigation rights are administered by entities (such as Tasmanian Irrigation) who are responsible for
operating irrigation districts.
Water licences and irrigation rights are statutory water entitlements. They are transferable and
separable from land. The irrigation schemes owned, operated and developed by Tasmanian
Irrigation use irrigation rights as the statutory basis for water entitlements.
4. Tasmanian Irrigation
Tasmanian Irrigation is a state‐owned company responsible for developing and operating irrigation
schemes in Tasmania. As at August 2015, Tasmanian Irrigation has built and operates twelve
irrigation schemes, owns the infrastructure of two locally managed schemes, and is at various
stages of developing a further five schemes known as "Tranche Two".
The capital cost of the irrigation schemes currently being developed by Tasmanian Irrigation is a
shared partnership between the public and private sectors. A total of $220 million has been made
available by the Australian and Tasmanian Governments for Tasmania Irrigation's Tranche one
schemes which are nearing completion. Private investment is raised through the sale of water
entitlements. An additional $90 million of public funding has been made available to Tasmanian
Irrigation to complete Tranche Two.
The irrigation schemes currently being developed by Tasmanian Irrigation are designed to last 100
years, deliver water at an average annual reliability of at least 95% and are built to satisfy demand
in each region, with a threshold level of private commitment required before construction begins.

5. Water entitlements
Water entitlements are either irrigation rights or delivery rights.
Irrigation rights
Irrigation rights in the irrigation district will be issued under the Irrigation Clauses Act 1973 (“ICA”)
and are subject to the terms of the agreements titled “Irrigation Right: Scottsdale Irrigation
District”.
Irrigation rights confer entitlements to have an allocation of water made available for delivery
during each irrigation season. The entitlement arising under irrigation rights is defined as a volume
and denominated in megalitre (ML) units.
The allocations made to irrigation rights for an irrigation season are calculated by multiplying:
the entitlement held under irrigation rights on the opening day of the season; and
the allocation percentage notified by Tasmanian Irrigation before the start of the season
and any revision made to the allocation percentage during the season.
If revisions are made to the allocation percentage during a season, the resulting allocations will be
made on the basis of the entitlement held under irrigation rights on the day the revision is notified.
Irrigation rights do not provide secure rights to have water delivered but do so when held in
conjunction with delivery rights.
Reliability
Irrigation rights in the irrigation district are warranted to 95 per cent average annual reliability on
the basis of the conditions applying at the time reliability was assessed and that the scheme
continues to operate as it was originally designed. The warranty does not cover reductions to
reliability arising from climate changes or other natural causes.
95 per cent average annual reliability means that, during 100 consecutive irrigation seasons, the
sum of the allocations made to irrigation rights will be equal to or higher than 95 per cent of the
sum of the entitlements on issue over that same period without the allocation percentage
exceeding 100 per cent of entitlements in any season.
Irrigation season
The irrigation season for the irrigation district is determined each year on the basis of the prevailing
seasonal conditions and in consultation with irrigators. Each season will remain open for a
minimum period of 150 days (nominally 1 December to 30 April), but may be brought forward or
extended if warranted by demand and agreed by the scheme manager. The allocations made to
irrigation rights during an irrigation season are valid for use or trade during the whole of the
season.
Tasmanian Irrigation Pty Ltd Page 6 of 14
Delivery rights
Delivery rights in the irrigation district are subject to the terms of agreements titled “Zoned Flow
Delivery Right: Scottsdale Irrigation District”.
Delivery rights confer entitlements to a share of the capacity of the scheme to deliver water within
a zone during each irrigation season. The entitlement arising under delivery rights is defined as a
flow rate and denominated in megalitre per day (ML/day) units.
As the delivery capacity of the scheme is not subject to seasonal variation, the allocation made to
delivery rights for each irrigation season will equal 100 per cent of the entitlement held under
delivery rights on the opening day of the season.
Delivery rights provide assurance that capacity is available to deliver water at a set rate, when and
to where it is required. Flow rate entitlements give certainty over the timing of supply and
introduce a tradable product through which irrigators can plan water deliveries, manage seasonal
risks and maximise the benefit of their entitlements.
Zones
Delivery rights carry a zone nomination which relates to the zones of the scheme as shown on the
map of the irrigation district at the end of this document.
Zones arise because of variations in pipeline diameters and other factors that limit the capacity of
the scheme to deliver water to different parts of the irrigation district. Each zone originates from
the supply point to the irrigation district (i.e. the Camden Rivulet Dam) and extends to the furthest
downstream point of the zone as shown on the map.
A water entitlement holder is able to fully trade with all other water entitlement holders in their
same zone. Restrictions will apply to tradability with other zones. In general, the size of the
pipeline is reduced in stepped increments down the pipeline. As such, in most circumstances it is
possible to trade water upstream in the pipe, but not downstream. For example, water can be
traded from Main 3 zone back upstream to Main 2 zone, but not vice versa.
Term of water entitlements
The term of the water entitlements issued in the irrigation district is set to match the term of the
water licence issued under the WMA which will underpin the irrigation district’s supply. The term
of water licences are 40‐years with provisions for the renewal of water licences set out in the
WMA. If the term of the water licence that underpins the irrigation district’s supply is extended, the
term of water entitlements issued in the district will be extended by the extended term of the
water licence.
Tasmanian Irrigation Pty Ltd Page 7 of 14
6. Water trading
Irrigation rights and delivery rights are tradable within the irrigation district in accordance with the
ICA and the Trading Rules for the irrigation district.
Trades are made by transferring volume between irrigation rights and flow rate between delivery
rights. To take effect, a transfer must be approved by Tasmanian Irrigation and recorded in the
water entitlements register for the irrigation district.
Trade types
There are two categories of trades – entitlement trades and allocation trades – and three types of
transfers – permanent transfers, limited term transfers and short term transfers. Entitlement
trades include permanent and limited term transfers, while allocation trades refer to short term
transfers.
Entitlement trades are transfers of the volume and flow rate entitlements held under irrigation
rights and delivery rights. A permanent transfer (sale) will result in an absolute change in the
ownership of entitlements, while a limited term transfer (lease) will result in a change in ownership
for a defined period of time.
Allocation trades refer to transfers of the volume and flow rate allocations that have been made to
irrigation rights and delivery rights for a particular irrigation season. Because allocations are made
on the first day of a season, short term transfers will necessarily take effect entirely within one
season.
Tradability
The tradability of water within the irrigation district is regulated through the zone nomination of
delivery rights. A transfer of flow rate will only be approved if:
in the case of permanent transfers, the zone nomination of the transferor’s delivery right
is the same as the zone nomination of the transferee’s delivery right;
in the case of limited term or short term transfers, the zone nomination of the transferor’s
delivery right is the same as or compatible with the zone nomination of the transferee’s
delivery right; or
Tasmanian Irrigation approves the transfer on the basis that it does not exceed the
capacity limitations of the scheme taking account of all other delivery rights issued.
Conditions
Important additional conditions to Tasmanian Irrigation’s approval of transfers include:
that all money owing to Tasmanian Irrigation by the transferee and transferor is paid;
that the sale price of the transfer is disclosed;
in the case of transfers exceeding 12 months, that the transfer is consented to by the
holders of any registered security interests;
in the case of a permanent transfer, Tasmanian Irrigation is satisfied as to the credit
worthiness of the transferee; and
in the case of limited and short term transfers, the transferor remains liable for all money
not paid by the transferee in relation to the transferred entitlement or allocation.

To assist buyers and sellers of water entitlements establish connections, Tasmanian Irrigation has
launched the Tasmanian Water Trading Notice Board. The Notice Board allows parties to advertise
their interest in buying, selling or leasing water entitlements.
If you would like to place an advertisement on the Notice Board or view advertisements that have
been posted to the Notice Board by other parties, you can access the Notice Board via Tasmanian
Irrigation’s website at www.tasirrigation.com.au.
The Notice Board is a free service provided by Tasmanian Irrigation in support of the development
of the water market in Tasmania.

7. Water charges
The on‐going costs associated with the irrigation district and its related infrastructure are funded
through annual water charges, which comprise of fixed and transfer charges that are levied on
water entitlement holdings and variable charges that are levied on actual water supplied.
Tasmanian Irrigation has prepared estimates of water charges to assist interested parties to
forecast the likely future costs associated with holding water entitlements and being supplied with
water from the irrigation district. The estimates are based on cost information for 2013‐14.
Please be aware that the charges are estimates only and subject to change, and will be determined
each year on the basis of costs applying at that time.
The supply of water is not currently subject to GST and accordingly Tasmanian Irrigation does not
collect GST in respect of the water charges. Should the GST treatment of water change, GST may be
collected in the future.

* Water charges estimated in 2013‐14 dollars
** Assumes full 8,600ML scheme water usage and therefore full $12.46/ML Energy Rebate applied
*** Assumes minimal scheme water usage and therefore nil Energy Rebate applied
Fixed charges include an operations and maintenance charge, telemetry and asset renewal levy.
These charges are levied on water entitlement holdings and are payable regardless of whether any
water is supplied.
The operations and maintenance charge recovers the fixed costs associated with the irrigation
district, including costs associated with employee entitlements, vehicles, plant and equipment,
routine maintenance, compliance, administration, finance and insurance.
The asset renewal levy provides for refurbishment and replacement of significant scheme assets
and funds that may be made available in the unlikely event of a major scheme failure. Funds
collected through the levy are set aside in an asset renewal reserve for the benefit of the irrigation
district.
The gross energy revenue from the mini‐hydro will be shared between Tasmanian Irrigation and
water entitlement holders based on contribution to capital expenditure and is provided to water
entitlement holders as an energy rebate. The revenue generated is directly related to the amount
of water used by the scheme. The water entitlement holders share equates to $0.00/ML in a year
when no scheme water is used and up to $12.46/ML (assuming production of 5.36 GWh and a
wholesale energy price of $45/MWh plus Renewable Energy Certificates of $35/MWh) when the
full 8,600ML is used. In practice the energy rebate will lie somewhere within this range and would
be applied annually in arrears.

Transfer charge (dam fill)
Scottsdale Irrigation District: transfer charge estimates*
Pump Station Zone Charge
St Patricks All zones (general charge) $15.24/ML
* Water charges estimated in 2013‐14 dollars
The transfer charge is also payable regardless of whether water is consumed and is calculated as
the annual cost required to be recovered on each water entitlement to pay for the cost of
supplementing inflows into Camden Rivulet Dam by pumping water from the St Patricks River.
Apart from the first irrigation season, it may be possible to avoid paying the transfer charge if a
nomination is made ahead of the pumping season that water is not required for the following
irrigation season.
Modelling of winter flows under the CSIRO’s “historic (current) climate” scenario shows that, on
average, approximately 5,665 ML of water will need to be pumped annually from the St Patricks
River to underwrite 95% reliability.
The winter dam fill pumping cost for the St Patricks pump station of $23.13/ML equates to the
winter retail electricity price ($0.17/kWh) multiplied by the electricity consumption rate
(3.83/kWh/m) multiplied by the pumping head (35.5m). For a forecast average pumping year of
5,665 ML, the winter dam fill cost of $23.13/ML would equate to an average charge of $15.24/ML
of entitlement (i.e., $23.13 * (5,665ML/8,600ML)).
Variable charges (scheme supply)
Scottsdale Irrigation District: variable charge estimates*
Pump Station Zone Charge
St Patricks All zones (general charge) $8.36/ML
Waterhouse Waterhouse 1 & 2 (surcharge) $29.89/ML
* Water charges estimated in 2013‐14 dollars
Variable charges are payable on water supplied and vary across the scheme to reflect differences in
the cost of supplying water to different parts of the irrigation district. Variable charges recover the
costs associated with pumping water through the pipeline distribution network and are only
payable for water used by the irrigator. If you do not use any water in a season you will not have to
pay any variable charges.
The pumping charge for the St Patricks pump station of $8.36/ML equates to the summer
wholesale electricity price ($0.045/kWh) multiplied by the electricity consumption rate
(3.83/kWh/m) multiplied by the pumping head (48.5m) and is a general charge applied to water
users in all zones. As the St Patricks pump station is directly connected by transmission line to the
mini‐hydro power station, the wholesale electricity price may be applied during power production
periods. Other scheme pump stations detailed below, which are not directly connected by power
transmission line to the mini‐hydro power station, are subject to the retail electricity price.
Tasmanian Irrigation Pty Ltd Page 11 of 14
The pumping charge for the Waterhouse pump station of $29.89/ML equates to the summer retail
electricity price ($0.13/kWh) multiplied by the electricity consumption rate (3.83/kWh/m)
multiplied by the pumping head (60m) and is a surcharge to Waterhouse 1 & 2 zone users only.

*** Assumes minimal scheme water usage and therefore nil Energy Rebate applied
The forecast total charge for each supply zone comprises the fixed charge plus the transfer charge
plus the relevant variable charge for that zone.
8. Transmission Loss
Where water is delivered using a natural watercourse, transmission losses will be incurred from the
point at which it is released into the watercourse to the point at which it is extracted. These losses
primarily due to seepage into stream banks and the groundwater system. The losses will be
deducted from the amount of water that can be taken by an irrigator receiving water from the
river.
Transmission losses will be determined by DPIPWE under a watercourse authority to be issued to
allow the transportation of water from the scheme along watercourse. It is anticipated that the
following transmission losses will be applied: Brid River 0%; Hurst Creek (downstream of the dams
in the upper catchment) 0%; Great Forester River (Headquarters Road dam to Mackenzie Rivulet)
0%; Great Forester River (Mackenzie Rivulet to Parrs Rivulet) 10%; Great Forester River
(downstream of Parrs Rivulet and including the Waterhouse pipeline) 15%.
Although Tasmanian Irrigation expects that the transmission losses detailed above will be used in
determining the losses to be applied in the watercourse authority, it is unable to warrant those
transmission losses. In particular, the losses may be revised by an amendment to the watercourse
authority by DPIPWE if it is demonstrated that the losses specified in a watercourse authority are
incorrect in practice.
What transmission losses mean is that, for example, if you purchase 100 ML of water entitlements
in either the Great Forester River or Waterhouse supply zones, you will only be allowed to take 85
ML if all of the water is extracted within the 15% loss area.
Importantly, the fixed charge and transfer charge will be payable on the full 100 ML of water
entitlements held and the variable charge will be payable on the full amount of water released into
the Great Forester River.
Tasmanian Irrigation Pty Ltd Page 12 of 14
9. Connections
The water entitlements issued in the irrigation district are separate from land.
To access water from the irrigation district, a connection to a pipeline of the scheme needs to be in
place and associated with water entitlements through a connection agreement.
Connection agreements specify the location at which water may be accessed from the scheme, and
contains the terms and conditions of taking supply through a property outlet.
An important condition of connection agreements is that water taken from the irrigation district
may only be used on land that is covered by a Farm Water Access Plan (see section 10 below).
To discuss connection requirements, please contact Tasmanian Irrigation.
10. Farm Water Access Plans
A Farm Water Access Plan must be in place for every property that receives water from the
irrigation district.
Farm Water Access Plans are management tools demonstrating that the use of water is sustainable
and complies with Australian and Tasmanian Government requirements. The plans contain soil,
water and biodiversity modules and specify management actions where environmental risks
associated with irrigation are identified.
Farm Water Access Plans are completed by pre‐qualified consultants authorised by the Minister for
Primary Industries and Water. To keep costs to a minimum, Tasmanian Irrigation is able to assist
with the preparation of maps and baseline information required to complete farm water access
plans and can arrange for tendering work to the pre‐qualified consultants.
As an indication of the cost of preparing a Farm Water Access Plan, the net cost to landholders to
date has generally been $2,200 (inc. GST) or less, although this cost has included a $1,000.00
subsidy from the Tasmanian Government which has not currently been committed for unfunded
projects. This figure is provided as a reference only. The actual cost to prepare a Farm Water Access
Plan may be higher and will be determined at the time a quote is sought from a pre‐qualified
consultant.
Amongst other things, the factors affecting the price of Farm Water Access Plans include:
the size of the area to be assessed;
existing land capability data for the area to be assessed; and
the likelihood of threatened species, ecological communities or other matters of
environmental significance occurring in or near the area to be assessed.
Tasmanian Irrigation is required to conduct random annual audits of Farm Water Access Plans each
year to ensure compliance.
11. Pressures
Tasmanian Irrigation guarantees a minimum pressure of 5 m head (equivalent to 49 kPa or 7 psi) at
each property outlet connected to a pipeline of the scheme.
However, the actual pressure experienced at a property outlet may be higher depending on the
proximity of the outlet to a pump station or pressure reducing valve, the relative height of the
outlet and can also vary depending on where and how much water is being taken elsewhere in the
scheme.
Tasmanian Irrigation Pty Ltd Page 13 of 14
To assist irrigators to understand the range of pressures that may be experienced at an outlet,
Tasmanian Irrigation has prepared estimates of the range of pressures that are likely to be found
at different points along the pipeline alignment.
The provision of information on pressures is given on the basis of the current scheme design and
will not in any way limit the ability of Tasmanian Irrigation to amend the scheme design nor does it
create an obligation on Tasmanian Irrigation to warrant those pressures.
The only obligation that Tasmanian Irrigation will assume in relation to pressure is an obligation to
supply a minimum pressure of not less than 5 m head (equivalent to 49 kPa or 7 psi) at each
property outlet connected to a pipeline of the scheme.
Information on pressure estimates can be found on the map of the irrigation district at the end of
this document. If required, additional information on pressures can be provided by Tasmanian
Irrigation on request.
12. Property outlets
As part of the sale of water entitlements, Tasmanian Irrigation will install one property outlet for
each parcel of contiguous (adjoining) land that is operated as the same business.
A parcel of land is considered to be contiguous if it is operated as the same business,
notwithstanding the underlying title ownership of the land. Land may be considered contiguous
even if intersected by a road, railway or any other land unless the effect of the intersection is to
practically sever it for operational purposes. Clarification as to whether land is contiguous can be
provided by Tasmanian Irrigation on request.
Each property outlet supplied as part of the sale of water entitlements will be capable of delivering
at least three times the purchased flow rate, subject to any capacity constraint of the pipeline to
which an outlet joins. Depending on the amount of flow rate purchased, the size of outlets will vary
from 50 mm for a flow rate purchase of 0.08 ML/day (equivalent to 10 ML of volume) to 300 mm
for a flow rate purchase of 2.5 ML/day (equivalent to 300 ML of volume) or greater.
The table below provides a summary of the size of property outlets that are likely to be provided as
part of the sale of water entitlements. The outlet sizes have been estimated on the basis of
hydraulic and control restraints across the outlet assembly.
The provision of additional property outlets or property outlet upgrades may be purchased if
required. The table below contains prices for the provision of additional outlets with the difference
between outlets of different sizes constituting the cost of an upgrade.

* The actual capacity of an outlet will depend upon the final scheme design, the actual range of pressures available in
the pipeline at the point at which an outlet joins and the method for connecting downstream infrastructure.
The typical maximum flows displayed in this table are based on an assumption of 50 m of head (equivalent to
490 kPa or 71 psi) being available in the pipeline at the point on the pipeline where a property outlet joins. The
capacity of each outlet will depend upon the final design, the actual pressures available in the pipeline at the
connection point and the method for connection to private infrastructure.
** Outlets greater than DN200 are customised items. Pricing for DN300 outlets as shown in the table is indicative.
Actual pricing will be confirmed on a case by case basis.
