Featured Project

Hawks Prairie Reclaimed Water Satellite, Wetland Ponds/Recharge Basins-Phase 1

Project Description:
The LOTT Alliance is the regional wastewater treatment system serving the cities of Lacey, Olympia, Tumwater and northern Thurston County (LOTT) in Washington State. The core of LOTT's long-range wastewater resource management plan is production of Class A Reclaimed Water, which is the highest quality of reclaimed water as designated by the Washington Departments of Health and Ecology.

• The project had 600,000 BF of Timber that was logged. Property was then stumped, piled, and chipped.
• 11.5 acres of wetland ponds were constructed and lined with clay (then topsoil) and had a series of HDPE header pipes installed in them to control levels. The water that fed the ponds was reclaimed water from their treatment plant thru a 14” diameter pipe line.
• Construction of 8 acres of recharge basins also included installation of large 24” HDPE header piping, which were fed from a series of vaults and used to control the pond elevation.

Points of Interest:

• All 35 acres (including ponds)were planted with water lilys, and under water vegetation.
• Walking paths & kiosks for the public to view the site were also constructed.
• The ponds and recharge basins had to be completed before the completion of the treatment plant, in order to discharge water.
• Project was completed ahead of schedule.
