The project consisted of construction of a 6 million gallon
geosynthetic-lined secondary effluent storage pond, a subsurface
drainage system, a new pump station with new electrical service,
floating, mechanical aerators with control system, industrial piping,
motor operated valves, and a new access platform.
Work included constructing a temporary earthen cofferdam in an existing
evaporation pond to enable construction of the adjacent, new effluent
storage pond levees. Over 5,000 feet of perforated PVC underdrain pipe
was installed beneath the bottom of the new three acre pond. The
presence of high groundwater necessitated the installation of a
temporary dewatering system and use of a sliderail shoring sytem for
installation of the underdrain.
A wet well pump station was installed to facilitate distribution of the
effluent. A new electric service was installed to power the pumps,
motor-operated valves, and floating aerators. The new electrical
controls for these devices were integrated with the existing plant
