Riverside Park Water Reclamation Facility
Major capital improvements at the City's Water Reclamation Facility have
been ongoing since 1996. Additional modifications and upgrades will be
completed as necessary to ensure that:
- the facility's discharge continues to meet state water quality standards
and protect the Spokane River,
- the treatment plant provides for and adequately handles the increased
flows generated by new growth, and
- repairs/rehabilitation/upgrades to existing equipment are made as

Riverside Park Water Reclamation Facility Laboratory
The Riverside Park Water Reclamation Facility Laboratory provides, as its primary function, raw and treated wastewater testing as required by federal, state and local regulations. The biosolids are tested according to federal and state regulations for application of biosolids to farmland.
This also includes technical support for the Industrial Pretreatment and Stormwater programs, wastewater discharge monitoring (NPDES), and environmental monitoring (i.e. Spokane River).
The Riverside Park Water Reclamation Facility Laboratory is responsible for the process control of the advanced wastewater treatment system that treats up to 44 Million Gallons per Day from a collection system serving City of Spokane and Spokane County.
This is a seven-day per week responsibility.
The Laboratory also produces data that is included in the monthly Discharge Monitoring Report, describing compliance with the plant's NPDES permit, administered by Washington Department of Ecology.
Laboratory personnel also staff the Industrial Pretreatment Program. Industrial Monitors/Laboratory Technicians perform sampling and inspections in conformance with the regulations of the National Pretreatment Program. A laboratory chemist directs their activities and maintains the electronic database and performs other administrative functions.
Laboratory technicians also perform environmental monitoring of the Spokane River. Detailed sampling and analytical protocols are followed to ensure the data is representative.
The Stormwater program is a new addition to the responsibilities. Several sampling sites have "call out" capability, to notify staff to monitor characteristics of flow, infiltration rates, etc., and to collect samples.
