PECI designed a trailer washing facility to clean emptied biosolids trailers at a regional disposal facility. PECI evaluatde possible options and develop cost estimates for the following two key facets of design:
- Truck wash location; and
- Water clarity and disposal.
Four truck wash locations were evaluated. Options for increasing water clarity included chemical coagulation, electro-coagulation and water softening. The NTMWD 121 Regional Disposal Facility is not served by an existing sewerage system and recycle of flows was considered. Construction of the truck wash and associated facilities was completed in 2011.
