The LOTT Clean Water Alliance is a non-profit corporation providing watewater management services homes and businesses in the Lacey, Olympia, and Tumwater area. LOTT is responsible for two major wastewater treatment functions: handling flow management and long-range planning, and coordinating a relatively new service – the production of reclaimed water.
LOTT treated an average of 11.17 million gallons per day (mgd) of wastewater in 2015, up from 11.82 mgd in 2014.
Reclaimed water production at LOTT's Budd Inlet and Martin Way treatment facilities has increased since production began in 2004. In 2015 LOTT produced 1.83 million gallons of Class A reclaimed water per day at the two facilities, up from 1.64 mgd in 2014. "Class A" is a designation from the State Dept. of Ecology for water clean enough for public contact and most uses, except drinking. The City of Tumwater is one of the region's largest consumers of reclaimed water, using up to 600,000 gallons of water per day for irrigation at the Tumwater Valley Golf Course.
