The wastewater treatment process is energy intensive, and WTD is the largest user of electricity in all of King County government. King County will protect regional water quality while reducing energy consumption at the South Treatment Plant in Renton thanks in part to a generous grant from Puget Sound Energy. The PSE grant will help cover the cost to install new two energy-efficient agitation air blowers that pump air into wastewater so beneficial bacteria can more efficiently break down and treat pollutants.
