Reclaimed Water Facilities
The reclaimed water facility at LOTT's Budd Inlet Treatment Plant was the first of LOTT's planned reclaimed water facilities to be completed. In addition, LOTT's 20-year plan calls for construction of three satellite reclaimed water treatment plants located throughout the Lacey-Olympia-Tumwater urban area. As currently planned, each satellite would initially be built to treat at least one million gallons per day (mgd) and be expandable up to five mgd. Building the satellites in small increments is intended to allow "just-in-time" construction to meet future wastewater treatment capacity needs.
Budd Inlet Reclaimed Water Plant
The Budd Inlet Reclaimed Water Plant features a continuously back-flushing sand filter system, cleaning the water to meet Washington State's Class A Reclaimed Water standards. This reclaimed water is beneficially used in the downtown Olympia area instead of being released into the marine waters of Budd Inlet. The facility can produce up to one million gallons per day (mgd).
The City of Olympia Water Utility provides distribution services for reclaimed water from the facility at the Budd Inlet Plant. Current uses include:
Hawks Prairie Reclaimed Water Satellite
Construction of LOTT's second reclaimed water facility was completed in 2006, with operational testing and refinements continuing into 2007. The Satellite was built as three separate construction projects, with a total construction cost of over $30 million. The three segments included:
The Martin Way Reclaimed Water Plant, located on Martin Way E in Lacey, will initially produce 2 million gallons per day (mgd) of reclaimed water, and will be expandable to 5 mgd. This membrane bioreactor system will produce Class A Reclaimed Water to serve portions of Lacey and Olympia.
At the Hawks Prairie Ponds/Recharge Basins site, the Class A Reclaimed Water circulates through a series of five constructed wetland ponds, containing about 225,000 wetland plants. The ponds provide opportunities for public education, recognition, and acceptance of reclaimed water. Four large kiosks provide interpretive displays about reclaimed water, groundwater recharge, and natural features of the site. As the featured attraction is in a park-like setting, with walking trails and benches, the ponds also serve as an amenity for the surrounding area by offering visitors the opportunity to view and enjoy a wide variety of animals, birds, and aquatic life.
Water from the constructed wetland ponds flows to the rectangular groundwater recharge basins. From there, the water infiltrates through the soils to a shallow underground aquifer.
