Northwest Water and Sewer District (NWWSD) Biosolids Management Plan

Wessler staff provided professional services in conjunction with the preparation of a comprehensive biosolids management plan for seven wastewater treatment plants owned or operated by NWWSD.

Our services included review of previous reports and other available information related to the existing solids handling facilities; site visits to validate layout, evaluate conditions, and review current operational processes; review previous discharge monitoring reports, raw influent data, and other data to calculate current quantities of solids production; and evaluate alternatives for biosolids handling improvements. The results of findings were summarized in the biosolids management plan.
