The City of Hood River contracted with Bell Design Company to update the City’s Water Master Plan, Sanitary Master Plan, and Stormwater Master Plan. BDC sub-contracted out the Sanitary Master Plan to HBH consultants and the Stormwater Master Plan to Salmon River Engineering.
The Water Master Plan involved working with City and County planners to determine where and when the system would grow, to evaluate the City’s current water supply and demands and to develop water forecast projections.
The project also involved converting the old hydraulic model over to a GIS based system and updating the City’s mapping and water model to reflect changes that had occurred within the system since the last Water Master Plan. In addition this project involved identifying areas of low pressures, low flows, and high pressures within the water system.
The hydraulic model was evaluated under existing conditions, under the future 5-year condition, and under the future 20-year conditions to aid in identifying current and future problem areas within the system.
Capital Improvement Projects were developed based on these findings and by working with City staff to identify known problem areas within the system. Peak hour events and fire flow conditions were evaluated in the hydraulic modeling process.
The City’s onsite generating chlorination system was also evaluated for CT time compliance with EPA’ requirements for future demand conditions.
In addition, the City’s water rights and water conservation methods were evaluated and conservation projects were recommended.
