Background/Explanation:
This contract provided for the replacement of Pump Station 018, a duplex sanitary sewer pump station located at the Lakeview Mobile Home and Recreational Vehicle Park which exceeded its useful service life. The pumps were being replaced based on current flows, but the station is sized to accommodate the potential for future flows from potential development of the adjacent property. Discharge piping and valve assemblies will be placed aboveground for easier access and maintenance by County personnel.
Pump station repair, rehabilitation, and replacement is essential for the prevention of sanitary sewer spills. Several County stations are now over thirty (30) years old. As equipment becomes obsolete, it is necessary to upgrade to newer technology and communication options in order to repair deteriorated pumps and piping. These improvements are facilitated in order to keep the sanitary sewer collection system functioning at an acceptable level.
