In 1994, The Central Arkansas Sewer System which serves over 1500
customers in Sherwood, Arkansas undertook a $2.0 million sewer
collection system rehabilitation and wastewater treatment plant
improvement project to bring the system in compliance with State
Discharge requirements and bring the sewer collection system in
compliance with Arkansas Department of Health requirements. The
Central Arkansas Sewer System treats a flow of 0.50 MGD serving
1500 customers. The new treatment facility completed in June, 1995
converted the existing facultative lagoon to an activated sludge
system contained in an earthen basin utilizing the existing lagoon
as sludge storage. The activated sludge facility is followed by a
clarifier, tertiary filter and disinfection by ultra-violet light.
Discharge monitoring reports have shown TSS limits average less than
1.0 mg/l and BOD has averaged less than 3 mg/l. Wastewater quality
monitoring tests have met ADPCE permit limits since the system was
placed on line.
