About the WRRF

The Water Resource Recovery Facility (WRRF) is an activated sludge/tertiary filtration plant that processes 18.75 million gallon per day. Pollutants are removed from the waste stream through a combination of biological, physical and chemical processes. More than 40 tons of bio-solids are disposed at the plant per day. Trained professionals are working 24 hours a day at the WTP to protect the State’s water resources.

Treatment processes in use at the plant include aerated grit removal, flow equalization, primary clarification, course bubble air diffusers to supply oxygen to the activated biological solids, secondary clarification, disinfection , rapid sand filtration, dechlorination and post filtration aeration.

Liquid Treatment / Solids Removal
Preliminary treatment waste water enters the WRRP headworks (wet well) via a 54" influent sewer and passes through two parallel double-drum channel grinders to reduce the size of materials in the influent. The influent is then pumped up to grade level where it flows through an aerated grit removal system. Flow leaving the aerated grit tanks enters a 5.3 million gallon aerated flow equalization basin by gravity. From there the waste water is pumped to the primary treatment system .

Solids Disposal
The grit removed from the aerated grit chambers is processed by two grit washers, deposited in two six-cubic yard containers which are trucked to an off-site land fill as needed.
