Severn Trent provides a full-service contract for this 8-mgd, two-stage activated sludge wastewater treatment plant. The wastewater processes include raw wastewater pumping, primary settling, and carbonaceous activated sludge. The plant treats 4-mgd, but has a capacity to treat 8-mgd. The City remains responsible for metering, billing, and collections.

Approximately 40 percent of the flow to the wastewater treatment plant are generated by local industry. Severn Trent has played an instrumental role in assisting the City to implement improvements to the City's Industrial Pretreatment Program. If compliance is not met, Severn Trent is responsible for the fines.

Negotiations have just been completed for the installation of a Biological Nutrient Removal (BNR) system. The new contract has a provision to extend the existing operations and maintenance contract for an additional 22 years.

ESTIMATED/ACTUAL COST SAVINGS— Capital Upgrades, Consumer Rates, and Fees

Severn Trent invested over $3 million in capital improvements, including modern sludge handling equipment, stand-by power generators, and plant automation systems. The construction of a dedicated building for the installation of a new belt press and the innovative approach of using ferrous chloride to precipitate hydrogen sulfide helped to significantly reduce sludge disposal costs and control the odor problem that had historically plagued nearby residents.

The value of the plant is estimated at $200 million, while the value of the agreement is valued at $50 million.

There are no concession fees paid by Severn Trent to the City.


Severn Trent employs 10 workers, who were employed by the previous operator of the plant. Some employees were originally municipal employees. The current employees are not unionized.
