SLUDGE HANDLING NARRATIVE
At design flow the Maury Sanitary Land District WWTP 1s anticipated to produce approximately
330 lbs/day of excess activated slugged (1,580 gpd at 2.5%) based on a flow of 225,000 gpd and
influent BODS of 270 mg/1. Excess sludge is wasted from the oxidation ditch to an adjacent sludge
holding lagoon with a volume of approximately 2.7 million gallons representing a detention time of
1,709 days Wasted sludge is allowed to decompose in the lagoon. Cleaning of the lagoon will be
accomplished once significant accumulations are observed. Supernatant from the lagoon is returned
to the WWTP.
Groundwater contamination due to the use of Cell No. 1 for sludge digestion/holding is not
anticipated to be a problem. Cell No. 1 was constructed in natural clays with a coefficient of vertical
permeability of less than 1.0 x 10-' cm/sec as reported in the Soils Report prepared by Atec
Associates. Clays were identified in all borings at the site extending to depths of 8 to 17 feet with a
groundwater level identified at 20 feet below ground. A total of three groundwater monitoring wells
are existing at the treatment plant site.
