PROJECT HIGHLIGHTS

Commissioned January, 2006 Domestic WW, Greenfield Permit(s); Discharge 12/NA /NA    (TN/TP/Turbidity) Municipal ⇒ Stream MMF Capacity: 1.0 MGD $5.28/gal 2 FTE (Full‐Time Employees)
A constrained site and the need for higher quality effluent made MBR the technology of choice for the Star Sewer & Water District.

DESCRIPTION

With the increase in wastewater flow, the Star Sewer & Water District needed to both expand the capacity of the existing lagoon facility and upgrade the quality of the effluent from the plant in order to meet the strict discharge guidelines for the receiving stream. The facility also needed to be easily expandable to allow the plant to match the City’s future needs, as well as being able to handle low startup flows. The new plant had to be the simple and easy to operate.  Following grit removal and fine screening, the biological treatment process consists of anaerobic, anoxic and aerobic treatment stages. This state‐of‐the‐art facility is a great example of how a small community can tackle modern problems of growth while continuing to protect the environment and natural resources.
