Sandy Creek pump station getting a $1.6M update

Henderson is moving ahead with construction of the aging pump station on Sandy Creek.

The city council agreed to apply for funding through the Clean Water State Revolving Fund in February 2012.

Last year, the city received a $1.6 million loan through the clean water fund to renovate and update the Sandy Creek Sewage Pump Station, which no longer pumps at rated capacity. This means it’s more likely to discharge into nearby waterways.

Construction is expected to be finished by February 2015.

This project will install a tap to prevent a catastrophic event, such as a flood, from taking place if there is overflow into the creek.

It also includes a new mechanical screen and conveying system, new pumps, a flow meter, valves, piping, new electrical room and new generator.

The outdated sewage pump station has overflowed several times in the past few months as a result of heavy rain.

In early April, Henderson Water Reclamation Facility Director Tom Spain confirmed 9,150 gallons of untreated wastewater overflowed into Sandy Creek, which is part of the Tar-Pamlico River Basin.

The amount of rain was greater than the pump station could handle.

On Jan. 22, the Sandy Creek Sewage Pump Station, located at 482 Rock Mill Road, overflowed 190,000 gallons of untreated wastewater over the course of eight hours. The water entered Sandy Creek.

The overflow caused what the wastewater treatment industry calls a bypass, as a result of inflow and infiltration from the heavy rain, according to Spain. The volume of water exceeded the station’s pumping capacity.

The bypass was caused by multiple pump drive system failures that made it impossible to operate a pump.

There was another overflow on Dec. 31.

Heavy rain caused the sewage pump station to overflow more than 7,500 gallons of raw sewage into the Tar-Pamlico River Basin.

The amount of rainfall and water run-off into the creek most likely dilutes the harmful effects of the untreated wastewater.
