As a utility in one of the fastest-growing regions of Puget Sound, the LOTT (cities of Lacey, Olympia, and Tumwater; and Thurston County) Alliance has taken an innovative approach to sustainability: managing growth one chunk at a time. The utility’s Wastewater Resource Management Plan – now 8 years in place – calls for LOTT to closely measure conditions and add capacity in “bite-sized” increments to match treatment and conveyance needs as closely as possible. The plan also marks a shift toward using wastewater as a resource, through reclaimed water and groundwater recharge. Although these methods have been used in dry climates for many years, they are new to the Pacific Northwest.
