Numerous solutions were researched to salvage the three contaminated wells, ranging from mixing the water with the one good well to dilute the Uranium levels before distributing it to the residents. Another option was to research what layer of the strata the Uranium was leaking into the wells at and attempt to seal off that layer.
In the end, the only solution was to dig three new wells in different locations and at different depths to source water that was uncontaminated. In the process, the system was expanded and updated significantly to handle the usages demands of the residents. The most significant feature added was a 750,000 gallon tank that would be used to support peak demand usage as well as provide adequate reserves to meet fire flow requirements.
Resident behavior showed that afternoon and evening use in the summer months was highest, so the water tank was utilized during those times, keeping pressure up along the entire distribution system.
To save the City operating expense, the well closest to the water tank was setup to fill the tank directly, reducing the size of pump needed, from 125hp down to 75hp, and was scheduled to run through the night when electricity rates were lowest. As demand was needed from the water tank a small 40hp booster pump was all that was needed to distribute the water to the system, saving the City energy costs as well.
