Town under DHEC consent order
By Stan Welch – The focal point of the Williamston Town Council’s work session Tuesday night was the imposing of a consent order by DHEC, as a result of problems with the town’s wastewater treatment system.
Those problems extend well back into the last decade or more. In fact, the town was released from a previous consent order as recently as October of 2014. The respite was brief, with the occurrence of a sewage overflow from a manhole, as the result of heavy rainfall (two inches)in a relatively brief period in early February. Obstruction of the line by tree roots was also deemed a contributing factor.
Consequently, DHEC issued a notice of violation based on a series of reports in late 2015 which reflected daily violations of fecal coliform levels at the treatment plant, which were also the result of heavy rainfalls. The chronic problem is the condition of the town’s sewer lines, which are outdated and which are subject to inflow and infiltration (I&I) during rain events. The I&I lets storm water enter the lines and flow through the treatment plant, reducing its effectiveness and leading to violations of the standards set by DHEC.
