MAP: Sewer basin to be inspected

November 23, 2010 | 1:44 p.m. CST
Beginning this week, TREKK Design Group LLC will be testing sewage flow and sewer lines in Columbia’s sewer Basin D, along Broadway, Ash Street and Stewart Road. Basin D is just one of several sewer basins in Columbia with problems due to excess inflow and infiltration. Inflow refers to stormwater entering the sewer basin from from outsides sources, such as storm drains and sump pumps. Infiltration occurs when groundwater enters the sewer basin through cracks caused age or deterioration.
