SEATTLE — Heavy rains like Monday’s record 2.13 inches in Seattle usually cause sewers to overflow directly into Puget Sound.
The Environmental Protection Agency has been increasing its enforcement of such pollution and has been negotiating a plan with King County to meet federal standards by 2030.
The Seattle Daily Journal of Commerce reports the plan calls for nine projects that would cost $747 million. Two are new treatment plants and the other seven projects involve underground tanks and pipes. They will be funded through bonds backed by customers’ sewer bills.
Wastewater Treatment Director Pam Elardo says she hopes the agreement will be signed by King County Executive Dow Constantine by the end of the year.
The goal is no more than one overflow a year.
