KSA installs new grit sytem at WWTP

12 October 2017

The grit removal system at the City of Mount Pleasant’s Southside wastewater treatment plant (WWTP) had been in use since the facility’s commissioning in 1989 and had reached the end of its life. Grit removal technology has advanced considerably since the original grit removal system was installed. These systems are now capable of greater removal efficiencies. Because of this, KSA was hired to remove the existing grit system and install a new one. This installation included a new grit chamber, pump and washer as well as mechanical equipment, piping and the associated appurtenances and electrical controls.

The existing WWTP included a grit pump pit that was located approximately 15 feet below grade. The pit was a hazardous, confined space in which operators frequently worked. Instead of reusing the existing pump pit, KSA’s design team relocated the new grit pump equipment on top of the grit chamber to provide a safer environment for the plant’s operators.
