Innovative Water Recycling

Facility Facts Location: Buckeye, ArizonaProject Type: Design-Build-OperateCapacity: 3.6 MGD expandable to 7.2 MGD

(originally built and expanded from 1.2 MGD)Footprint: 1.5 acresProcess Design: Hybrid Sequencing Batch Reactor (SBR)

Sundance Water Recycling Facility

PERC Water provided Design-Build-Operate services for both Phase 1 and 2 of the Sundance master-planned community. The project guaranteed a fixed cost, construction schedule and value engineering during the conceptual design of the project. Phase 1 was completed with a 1.2 MGD capacity. Phase 2, which was completed in May 2009, can support approximately 14,400 homes.

The Sundance Water Recycling Facility (WRF) is a 3.6 million gallon per day PERC Water ASP® designed facility utilizing hybrid sequential batch reactor (SBR) activated sludge process for biological oxidation of organic matter and nutrient removal. It was designed, built and is being operated by PERC Water Corporation for the Town of Buckeye. The Facility has a unique design whereby all treatment of wastewater occurs in below ground tanks that are covered with 8,000 square feet of operations buildings constructed above the tanks.

The Sundance WRF is one of the first common-wall modular construction wastewater facilities with a special design where essentially no extra infrastructure was provided in Phase I, such that all future phase costs could be diverted to Phase II and beyond. This allowed costs to be properly distributed to the appropriate users when new wastewater generation was desired. Phase I, 1.2 MGD capacity, was completed in 2003 for about $7/gallon treatment capacity. Phase II infrastructure, 2.3 MGD of additional capacity, was then completed in 2009 for about $8/gallon treatment capacity.

Phase III, the final phase of treatment works expansion, increasing the capacity by 3.5 MGD, is projected to be the same cost per gallon, and will include additional infrastructure that will be simple to construct and easy to operate. All three phases of the treatment works will fit on a three acre site with complete passive and active odor control, aesthetic buildings on top of the tanks, and no wasted space. Costs for class A+ effluent in the State of Arizona including the features described typically cost upwards of $12/gallon of treatment capacity. The phase II expansion was completed, started up, and tested with phase I treatment works remaining online. This project realized all of the benefits of a true modular designed facility.

Key Design Features

PERC Water has served as the Design-Build-Operate entity of two water recycling facilities in the Town of Buckeye, Arizona and has entered into a total of nine separate Design-Build-Operate contracts for facilities in Maricopa, Arizona. The site designated by the Town of Buckeye, Arizona for the Sundance Water Recycling Facility is directly across the street from a residential community.

To alleviate residents’ concerns, PERC Water developed an outreach program, which included Town Hall meetings and facility tours, to educate and ensure the residents that the Sundance Water Recycling Facility would be a good neighbor. The facility is within 100 yards of the neighboring home community and has had no complaints of noise or odor

Rapid growth in the area and surrounding communities just east of Sundance prompted the Town of Buckeye to expand the facility to accommodate the growing population. Fortunately, the flexibility of the PERC ASP® design allowed the Town to expand the planned capacity from 1.2 MGD to the cumulative capacity of 3.6 MGD without having to purchase additional land. Phase 2, which was completed in May 2009, can support approximately 14,400 homes.

The Valley Forward Association awarded the Sundance facility in 2003 with an “Award of Merit” for Environmental Technologies due to its ability to produce Arizona Class A+ effluent without chemical additives.
