Crystal Garden Wetlands   

 The City of Avondale Wetland project consists of a series of treatment cells designed to treat the City’s Salt River Project (SRP) and Central Arizona Project (CAP) water allocations to aquifer water quality standards. The project is surrounded by the Crystal Gardens neighborhood and is open to the public. The project was designed to be an amenity to the community as well as a source of drinking water.

The 72 acres of treatment cells are separated into three flow systems, northwest (cells 2 to 5), northeast (cells 6 to 9) and south (cells 11 to 14). Water flows into the Wetland via an SRP canal. The first stage is the sedimentary cells (cells 1 and 10), these unplanted cells are designed to allow solids and heavy material to settle out. Water then flows by gravity through the planted treatment cells where the wetland ecosystem allows the nitrogen cycle to occur naturally.

Avondale Aquaculture Program  

The City of Avondale's Aquaculture program raises Tilapia to sustainably and cost-effectively control algae in the Crystal Gardens Wetlands. City staff raise approximately 6,000 fish annually in a fish hatchery and release them into the wetlands. The hatchery utilizes a recirculating closed loop system to conserve water. Since the launch of the program, the City has not needed to use any chemical applications in the Crystal Gardens Wetlands Treatment Facility.
