In 2010, South Davis Sewer District (SDSD) determined that possible hydraulic problems existed in their various pump stations operating within their treatment plants. A hydraulic analysis was conducted for the pump stations to diagnose the problems and provide possible alternative solutions. This analysis was conducted by using hydraulic minor loss equations to determine the amount of flow that the pumps were capable of producing and then comparing those results to the required demands in the plants. In cases where the flows were lower than needed, alternatives were designed to provide the required flows.

In the south plant the pumps were capable of meeting the hydraulic needs of the plant. However, in the north plant, the pump stations were far under capacity and alternative designs were provided. It was recommended that the first pump station add a fifth pump in order to generate the extra capacity needed while the second station would have their pumps replaced with new pumps capable of providing a slightly larger flow capacity. It was also recommended that SDSD review other areas of treatments and hydraulics that may have been causing additional problems.
