History

In 1964 the cities of Reno and Sparks, via an inter-local agreement, commissioned the construction of the Truckee Meadows Water Reclamation Facility (TMWRF).  Since that time the cities have jointly owned and operated the facility.  Originally TMWRF had a permitted capacity of 20 millions of gallons per day (MGD).  In 1978-80, capacity was expanded to 30 MGD and phosphorous removal facilities were added.  In the 1980’s the capacity was increased to 40 MGD and nitrogen removal facilities were added. In 2007, another expansion project was completed and the capacity was increased to 46 MGD. Recently, capacity assessments were performed and TMWRF’s capacity was down-rated to 39.8 MGD.  The capacity is shared between the cities of Reno and Sparks and portions are leased to the Sun Valley General Improvement District and Washoe County.

The facility’s governance has been established through a series of inter-local agreements between the cities of Reno and Sparks.  The 1996 agreement created the current form of the Joint Coordinating Committee (JCC) which is composed of representatives from the two cities along with the Sun Valley General Improvement District and Washoe County.  The JCC has the duty to advise the City Councils of Reno and Sparks with respect to all matters related to the maintenance, repair, expansion, replacement, improvement and operation of TMWRF, and policies related thereto.  The City of Sparks serves as the operating authority and the City of Reno directs major capital improvements.

TMWRF is a biological nutrient removal plant that uses separate nitrification and denitrification processes for nitrogen removal and biological and chemical processes for phosphorus removal.  Reclaimed water is discharged to the Truckee River or is pumped to effluent reuse sites in the cities of Reno and Sparks.  Solids are thickened, anaerobically digested, dewatered and hauled to the local landfill for disposal.  The methane gas produced by solids digestion is used to generate the hot water which is used to heat many TMWRF’s buildings.

TMWRF serves the central Truckee Meadows, including areas within the City of Reno, the City of Sparks, the Sun Valley General Improvement District, and portions of Washoe County that are within the Truckee Meadows and the Spanish Springs Valley.  The sewer system conveys wastewater flows from the Truckee Meadows Valley, Spanish Springs Valley, Sun Valley, Verdi/Truckee Canyon, and portions of the Golden Valley and Lemmon Valley hydrographic basins.

Under the direction of the Plant Manager, TMWRF has a staffing complement of 45 full time employees.  The management team is comprised of the Plant Manager, Operations & Maintenance Manager, and Laboratory Supervisor.
