Welcome to Water Environment Services

Water Environment Services (WES) provides Wastewater Collection & Treatment and Biosolids Reuse for seven cities and several unincorporated areas in Clackamas County. Stormwater Management, On-Site Sewage Disposal, and Water Quality and Stream Enhancement projects are also coordinated by WES.


On Monday, July 6, a Circuit Court Judge rejected legal claims filed by the Tri-City Service District challenging the legality of a fee imposed by Oregon City on businesses or utilities operating within city-owned rights-of-way. The fee imposed in October 2013 sought to assess the district nearly $200,000 last year, with the amount increasing annually. The district challenged the fee as excessive, believing that it presents an unnecessary expense for ratepayers.

No decision has been made on whether to appeal the ruling. The district and its municipal partners are considering all legal options and the implications of the ruling on district customers.
