Pure and reliable potable water is vital to any development’s success. PACE provides a unique hands-on background and insight

into planning, consulting, design, and implementation of potable water solutions. As part of the planning process, PACE develops

integrated water balances for sustainable water use and conservation including water recycling. Also included in the planning phases

are selection of appropriate water sources, conveyance, and distribution. Once the source has been selected, PACE has an extensive

background in water treatment including the removal of trace constituents such as iron, manganese, arsenic, and uranium, as well as

salinity reduction through desalination. Treated water must be properly stored and transmitted to customers during average, peak, and

fire demand periods, and PACE has engineered dozens of different types of water storage tanks, booster pump stations, and control

systems to deliver water at a constant, ideal pressure. Finally, because of PACE’s extensive construction, operations, and controls

experience, we are able to troubleshoot, startup, and train staff on the operation of PACE-engineered systems.

osmosis (RO), nanofiltration (NF), ion exchange, electro deionization reversal (ED/EDR) and advanced oxidation. PACE has extensive

expertise in water chemistry and advanced water treatment with the added capability of in-house desalination/water reuse piloting and

R&D, which enables us to adapt the latest and best available technologies to the most challenging source water, producing high quality

water with high recovery and minimum generation of waste. Together, with our broad experience with design, construction and operations

of water treatment, storage and distribution facilities, PACE provides complete engineering services including planning, consulting, design,

construction support, start-up support and operations consulting to meet and exceed the increasing demand of our clients for both water

quality and quantity with practical and economical solutions.

PACE’s ability to restore or create successful wetland systems relies on the understanding of the operation of

hydraulic systems and processes in nature, as well as the ability to assess, recreate, and manipulate hydrology.

Standard “cookbook” approaches have limited values and success depends on the combined expertise, which

integrates hydrology and biology with a strong engineering technical foundation. PACE’s philosophy for the

design of these systems is that they should be “self-sustaining” features of the landscape and integral parts of

an ecosystem.

Kings County Green CityKings County, California

Kings County Green City is the largest green development project ever undertaken by PACE. The 13,172-acre (5,330 hectares) development will include over 50,000 homes for 150,000 residents and create 40,000 jobs. Kings County Ventures will feature a championship motor speedway and destination resort hotels and entertainment venues in Central California’s San Joaquin Valley located between Los Angeles and San Francisco. PACE developed ways to create the most environmentally responsible community possible. Original concepts being developed by PACE under Mr. Perslow’s direction include linking the community with a waterway that also functions as a water distribution system for recycled water, and solar power generating units which float on water reservoirs.

PACE is responsible for designing the stormwater, potable water, wastewater, and effluent reuse infrastructure. During the initial planning process, PACE prepared the Water Supply Assessment to verify the potable water supply is sufficient, a critical piece to proving the development viability. Master Planning documents were prepared to address floodplain issues and stormwater storage and conveyance, as well as the preliminary design of potable water, wastewater and recycled water storage, treatment and conveyance facilities. Water modeling software and GIS was used to by PACE to analyze alternatives under various use scenarios. Following the approval of the Master Plans, all stormwater, potable water, wastewater, and recycled water infrastructure and treatment facilities will be designed by PACE.

MOUNTAIN HOUSEStormwater, Potable & Wastewater Management Plan

Trimark Communities, LLC, a subsidiary of Sunchase Holdings in Phoenix, AZ, developed a rural area on the border of the Alameda County / San Joaquin County, about 60 miles east of San Francisco. Here, Trimark has created a development known as Mountain House, a self-contained, 4,784-acre (1,900 hectares) master planned community that is home to 43,500 residents. Incorporated into this new town is an innovative, natural approach to water resources management. PACE led the engineering efforts on all of the project's water resource issues, including potable and non-potable water distribution systems, a water reclamation facility development-wide stormwater management planning and creek restoration design services for Mountain House Creek, one of the development's signature features.

Advanced Elements:Creek Restoration:

• Conversion of creek from an agricultural ditch into a naturalized creek flowing within a biotic, multipurpose corridor.

• The creek eliminated numerous large storm drain pipes, several large, dry extended detention-basins BMPs, and greatly reduced the cost of stormwater infrastructure without compromising safety and treatment.

• Using five precast concrete bridges, disturbance to the restored riparian zone was prevented, permitting issues were avoided and construction time was reduced.

Water Reclamation Facility:• Sludge Processing to Meet EPA Class B Biosolids

Requirements.• Treatment takes place in underground tanks, significantly

reducing land requirements and improving the facility's aesthetics.

• A unique structural concrete deck design reduced construction time and cost.

• The original 0.45 MGD (1,700 m3/day) facility resided on 21 acres (8.5 hectares) of land, while the new 3 MGD (11,400 m3/day) per day facility resides on only one acre of land.

Mountain House Master Planned CommunityMountain House (near Tracy), California

• Tremendous energy savings through the use of micro-fine bubble diffuser panels in the SBRs and the use of low-energy Flygt “banana blade” mixers.

Water Distribution System• The irrigation system consists of 2,500 gpm (9,500

lpm) on-demand constant high pressure pump station design including a canal check dam, 1/8 inch (3mm) stainless steel wire screen intake system, and hydropneumatic tank and pump station building which houses pumps, filters, and electrical and associated piping and instrumentation.

• The irrigation station also has a set of primary intake screens and 100 micron filter discharge filtration system, which strain debris from the canal water and prevent zebra mussels from clogging equipment.

• The potable water system includes two 3.7 million

gallon (14,000 m3) partially submerged concrete storage tanks with two zone domestic and fire pumping station (max 3,000 gpm (11,400 lpm) domestic plus 3,500 gpm (13,250 lpm) fire) within the same structure. The 150 foot (46 m) diameter, 31 foot (9.5 m) tall tanks were constructed partially underground to reduce the aesthetic impacts to the adjacent community college and residential development.

• PACE designed two separate sets of potable water booster pumps in an architecturally pleasing pump house structure and a pressure reducing / sustaining valving and metering station.

• The pump station has redundant pumps, automatically transferred back-up power, disinfection injection and monitoring, and full remote telemetry and security systems with full-motion video surveillance.

Global Water Intelligence WastewaterPlant of the Year Commendation

PACE provided engineering, permitting and start-up services as a subconsultant to PERC in 2004 for a new, state-of-the-art 3.0 MGD (11,400 m3/day) water reclamation facility. The facility was designed to meet the strict CA Title 22 effluent requirements for unrestricted reuse and utilizes a two-tank SBR process for biological oxidation of organics and secondary clarification. Tertiary treatment is accomplished through the SBR, Aquadisk cloth media filtration, and advanced UV disinfection. The Mountain House WRF is among the first facilities in the United States to utilize a UV Disinfection System certified under NWRI to meet California Title 22 requirements. In 2006, the Mountain House WRF was awarded the Global Water Intelligence Award for Water/ Wastewater Project of the Year.

PACE was responsible for a creative watershed planning program that included the Stormwater Master Plan Update for the entire development, the restoration and enhancement plan of the13,400 linear foot (4,000 m) Mountain House Creek for a proposed residential golf course and lake system. A unique and natural-based approach to the project creek restoration and combined stormwater management program integrated the use of created wetlands and the establishment of riparian corridors for runoff water quality treatment and flood conveyance within the creek restoration program.

The stormwater management features include pedestrian linkage and multi-function open space areas. Additionally, the plan eliminated numerous large diameter storm drains and detention basins by routing on-site runoff through the Mountain House Creek, residential lake system and golf course. This re-routing significantly reduced capital costs for stormwater management and ensured that Mountain House Creek will have year-round flows, thereby enhancing the environmental restoration and aesthetic quality of the development.

The station has redundant pumps, automatically transferred back-up power, disinfection injection and monitoring, and electric overhead crane assembly. PACE also provided the engineering permitting effort for municipality and County submittals and reviewed the contents of water balances performed for the municipality.

PACE prepared a Recycled Water Master Plan to incorporate all the reclaimed water generation sources and disposal options to determine the best locations for reclaimed water disposal throughout the construction of the Mountain House community. Recommendations were made

based on information gathered from various sources, site availability and economic efficiency of each option. Additionally, pipe sizing and layout were produced based on the recommendation of the plan.

PACE also provided master-planning and design services for a non-potable irrigation distribution system, 2,500 gpm (9,500 lpm) on-demand irrigation pump station from Byron Bethany Irrigation District Canal 155, and design of flow-metering and pressure reducing stations. The pump station design included a canal check dam, intake screens, hydropneumatic tank and pump station building which houses pumps, filters, and electrical and associated piping and

instrumentation. The station also has a set of primary intake screens which strain debris from the canal water and prevent zebra mussels from clogging equipment. The station pumps include two VFD main irrigation turbine pumps, and one single speed low flow turbine pump and the hydropneumatic tank is used during low flow demand periods to supply flow so the pumps will not over cycle.

Components: • Membrane Bio Reactor facility• Initial Capacity of 3.4 MGD (12,900 m3/day), with ability to expand up to 4.2 MGD (15,900 m3/day)• Three percolations basins• Largest Koch MBR facility in US

The existing City of Santa Paula Wastewater Treatment Plant was constructed in 1939 and most of the facilities have reached the end of their useful service life and are non-compliant with current regulatory requirements. The existing facility has a capacity of 2.55 MGD (9,700 m3/day) which is insufficient to meet future growth demands of the City and therefore additional capacity is required. The City is planning to replace the existing facility with a new Water Recycling Facility (WRF) and percolation system to be constructed on approximately 53 acres (21.5 hectares) immediately south of the existing facility. PACE was contracted as part of the design-build-operate-finance (DBOF) team to provide engineering for the new WRF, which will be designed as a Membrane Bio Reactor (MBR) with an initial capacity of 3.4 MGD (12,900 m3/day) and readily expandable to 4.2 MGD (15,900 m3/day) to meet wastewater flow projections for the year 2025. Also included in the new WRF design are three percolation basins with a combined surface area of about 15 acres (6 hectares) located to the west of the WRF site. The Santa Paula WWTP will be the largest Koch MBR facility in the United States upon completion. The WWTP is also the first DBOF municipal WWTP in California.

Masdar Water Features and Recycled Water TreatmentAbu Dhabi, U.A.E.

PACE was contracted to design 18 unique water features for the Masdar project in Abu Dhabi that function as normal water features when fully operational, and serve as elegant sculptures when dry. These 18 water feature designs include interactive fountains, reflective pools, water walls, bubble fountains, an oasis garden, and a mosque water feature. PACE also needed to be conservative with water usage throughout the project for the water features, since there are limited resources available for use. PACE proposed to use grey water as a solution to the limited water resource availability. PACE designed the water treatment and reuse systems for the system of water features, including the grey water treatment and sewage effluent treatment system, which includes a centralized water feature treatment system to provide a more cost effective and sustainable design approach. This treatment system includes a 100,000 L (26,400 gllons) water storage tank, silica sand and BAC filtration, UV disinfection, ozone generator and injector disinfection, pressurization, delivery and controls for the water feature elements.

Dateland Water Treatment Plant ExpansionYuma, Arizona

PACE is providing Dateland Public Service Co. with inland-desalination alternatives, engineering design, environmental permitting, and grant funding application services to improve and expand their existing groundwater Reverse Osmosis (RO) treatment system. The groundwater in the Dateland basin contains several trace contaminants including arsenic and fluoride. The groundwater also contains irrigation inhibitors boron, chloride, and sodium, and overall contains high levels of TDS. The contaminants must be removed to comply with primary and secondary drinking water standards. PACE investigated several process modifications and alternatives using Performance Based Specifications to deliver a cost effective, flexible and fundable project using an advanced RO process. The upgrade and expansion allows for the reuse of existing infrastructure, but with significantly higher permeate recovery than the existing RO system. It also produces more “wet” water from the existing supply, reducing waste and improving efficiency. In addition to the mechanical process work, PACE is also providing a preliminary alternative energy evaluation for the use of PV solar systems to power the expanded plant. The Dateland Water Plant Expansion is federally funded by USDA, Rural Development and Water Infrastructure Finance Authority.

Advanced Elements:· Investigation of several process modifications and alternatives using performance-based specifications to ensure Utility’s objectives were met and federal funds were secured.· Upgrade reverse osmosis system to innovative high recovery process to reduce waste and improve plant efficiency.· Alternative energy design for use of photovoltaic solar systems to further provide energy efficiency and lower capital cost.

Inland location of Desalination Plant requires high recovery to reduce evaporation basins' size.

Untreated Water Quality Proposed Treated Water Quality

PACE provided services for the improvement of both potable groundwater quality and reclaimed water quality for an lnland Water Utility in suburban San Diego, CA. PACE was retained to design, procure, install, operate, and report on a pilot water treatment system to verify a proposed plan to permanently reduce excessive salts and other contaminants in the water supply. By treating the potable water to high quality, better reclaimed water quality will be available for landscape irrigation and other uses because of lower salinity. The proposed type of treatment will also greatly reduce the salt additions caused by existing ion exchange, softening, and other water treatment processes which add extra salts to the distribution system and ultimately the groundwater. Because the utility cannot easily dispose of reject or waste flows, thus the proposed treatment process PACE has piloted is intended to effectively reduce the amount of reject into a small volume conducive to off-site hauling and disposal. The pilot system’s intent was to remove and concentrate the salt in the brackish groundwater to create a high quantity of clean water for potable use and subsequently for reclaimed water use.

Advanced Elements:• High recovery will allow zero liquid discharge of waste to the

groundwater basin• Use of vibratory shear enhanced process (VSEP) membranes

on reject brine from first membranes which reduces scaling despite precipitation of minerals

• The process removes nitrate which drastically reducing the addition of salts previously needed to regenerate existing equipment

• The system is modular and can be scaled with growth of the utility demand

The proposed system used in the pilot incorporates two stages of treatment. The first stage of treatment consists of multi-array spiral wound reverse osmosis membrane units with an intended product water recovery of 80%. The pilot system, due to its small size, used a single array system with a recirculation pump to simulate a two array system. The second stage of treatment will take the concentrate, or reject, from stage one and treat the flows to another 80% intended recovery using flat-sheet reverse osmosis membranes operated in a vibrating machine called VSEP, or vibratory shear enhanced process. Thus,

the total system recovery when combining both stages is intended to be about 95%. The remaining 5% will be highly concentrated reject which will require evaporation and/or offsite disposal. Although both stages require standard low-dose chemical addition to prevent efficiency-reducing scale caused by silca, barium, and calcium carbonate, the second stage VSEP treatment requires extensive pretreatment conditioning in order to achieve a sustained 80% recovery. This pretreatment process involves removing scaling components through softening processes or by adding acid to remove alkalinity.

The Municipality of Puerto Peñasco in Rocky Point, Mexico desires to improve the sustainability and quality of potable water for their residents and large tourism industry. PACE worked on the development of a comprehensive study to determine the feasibility of constructing a new 44 MGD (166,600 m3/day) seawater desalination facility for the City of Puerto Peñasco. Accordingly, they have moved forward with an ambitious plan to convert their entire existing and proposed future water systems to ocean desalination from the Sea of Cortez. This facility, when completed, will be one of the largest desal facility in Latin America. PACE provided the conceptual and preliminary design of the all facets of the facility from the seafloor raw water intake structures to the final water storage and pumping facilities. PACE also provided construction and operational cost estimating. Our team is currently advising and assisting the City with contract negotiations for a Design/Build/Operate/Finance delivery of the project. The first phase project will provide 11 MGD (41,600 m3/day) of potable water from desalination to provide for existing demands. Future phases include quadrupling of this capacity potentially including long-term transmission of treated water to the United States.

Advanced Elements:• Marine wildlife protection and beach sand filtration using

subsurface sea floor intakes.• Natural disaster damage-resistant and corrosion resistant

beach pumping station with submersible equipment.• Efficient treatment design with recycling of both

pretreatment and second pass rejects.• Pretreated water storage to desalinate during degraded

sea water quality.• Integrated “tank within a tank” post treatment

remineralization and disinfection.• Achieves excellent water quality for multiple uses including

irrigation, such as boron, chloride, and sodium removal to low levels.

Irrigation water is relatively pristine, comprised of less than 400 mg/L total dissolved solids (TDS), but the small amount of TDS, or salt, contained in irrigation water accumulates in the soil after repeated application over long periods of time. Salt buildup occurs because evaporation from the sun and transpiration through plants removes much of the applied water, and the salt remains behind in the soil paste. If this accumulated salt is not periodically flushed from the system, degradation of plant growth conditions will occur. Thus, water is intentionally over-applied to the farms to flush the salts from the soil. The fraction of over-applied water is called drainwater. Drainwater runs off the farms by both surface and subsurface flow through underground drains.

Agricultural Drainwater is Discharged to SurfaceWaters & Vast Evaporation BasinsMost drainwater in California is either discharged with relatively pristine surface waters, where pollution occurs, or is sent to large basins where the water is evaporated by the sun. Because the net evaporation minus precipitation rate in Central California is approximately five feet per year, about 200 acres of land is necessary to evaporate one million gallons per day of drainwater.

Why Isn't Agricultural Drainwater Utilized?

Drainwater currently has no value because it is considered salty, or “brackish." Potable drinking water in one’s tap generally has TDS less than approximately 500 mg/L. Drainwater streams have TDS concentrations exceeding 5,000 mg/L due to long-term flushing of saline soils. There are eight mineral constituents which comprise approximately 98% of the TDS:

These eight constituents themselves are generally not toxic to plants, with the exception of chloride at concentrations exceeding 200 mg/L. However, the presence of high concentrations of these minerals together result in the plant having difficulty obtaining water due to increases in osmotic pressure.

PACE provided services for planning, design and construction of a unique surface water treatment system using a series of wetlands lagoons. The wetlands treats up to 15 MGD (57,000 m3/day) of contaminated drainwater to drinking water standards for groundwater recharge through a spectacular series of interactive lagoons. The 83 acre (34 hectares) lagoon system not only provides water treatment, but also creates a park-like setting and waterfront view home site for an 800-home mixed-use subdivision.

Advanced Elements:• Water treatment is accomplished by steady flow through a series

of 16 stepped wetland lagoons (lakes). • Approximately 30 acres (12 hectares) of wetland treatment

islands, planted with effective wetland plants, create a visual amenity, wildlife habitat, and a cool system of lagoon inlets and outlets, weir control boxes, hydraulic piping and valves, and water flow and water quality monitoring.

• The wetland design and functionality was presented at numerous state and national conferences, and the project

received an Environmental Excellence Award from the Valley Forward Association for Environmental Technologies in the Public Sector.

• Treatment system has successfully processed and recharged over 10.5 billion gallons (40 million m3) of canal water contaminated with agricultural runoff to comply with drinking water standards for groundwater recharge since August 1999, when it became fully operational.

PACE is also the lead designer for all man-made lakes, streams, and other water features at DancingGreen. The large lake will be divided into three main areas, each with unique water quality requirements and recreational amenities. In addition to serving as a primary recreational and aesthetic feature of the site, the lake will serve as the stormwater treatment facility for the entire site, and PACE has designed advanced treatment systems into the lake to maintain exceptional water quality despite the presence of stormwater runoff, people, and wildlife in the lake.

In addition to services directly related to the many water-related aspects of the project, PACE is providing consulting and design services related to site layout, grading, recreational programs, transportation, attracting wildlife, and aesthetics on the site. Our extensive experience with resorts, man-made lake communities, and a wide range of environmentally-conscious projects gives us unique insight into the methods in which a project can be designed with nature in mind, to enhance, rather than damage the natural environment, provide both a great experience for the visitor and a healthy environment for generations to come.

Bridgeport Lake is a 15-acre (16 hectares) manmade lake providing both a visual and natural resource amenity to the adjacent Bridgeport development. With a tributary drainage area of 75 acres (30 hectares), Bridgeport Lake provides several urban storm water pollution treatment and water quality maintenance features that serve to fulfill stormwater detention and treatment requirements for the Bridgeport development. In addition to being the focal aesthetic feature of this high-end development, the lake system also serves as the primary drainage facility for the site and as a water quality and urban storm runoff enhancement facility.

Advanced Elements:• Bridgeport Lake provides retention for 3 inch (76 mm) over its entire surface area or 1.3 acre (0.5 hectares), which is more than enough capacity to retain the first flush of a storm event.

• Water quality filters collect initial runoff and retain it long enough for the majority of pollutants to be removed.

• Eliminated the need for several large diameter storm drain pipes by routing storm and urban runoff through the lake system.

• Lake water quality enhancers include biofilters, aeration, and wetland planters.

• Created premium land values surrounding lake.• Created habitat for various local wildlife species and environmental amenity for the local community.
