To ensure the optimum sump and storm sewer pipe performance, determine the in-place capacity of the sump downstream from the sedimentation manhole for each sump system. Testing takes place after a sump has been constructed.
NTA specializes installing sumps, and now has the capability of testing them to city specifications.
