Abstract:

The City of Baltimore has 3150 miles of storm drains, with a large percentage close to

100 years old, and 1,240 miles of sewer with ˜70% greater than 50 years old. The City's storm drain system has had a history of contamination, partly due to Sanitary Sewer Overflows (SSO) and partly due to illicit sanitary connections. A pilot study was conducted to develop a protocol for investigating illicit connections to the storm drain system, which would then be applied citywide. The pilot study was conducted in the Gwynns Run Drainage Basin, consisting of 1,600 acres and containing 415 storm drain manholes of which 53 manholes (an average of 13%) were tested over a period of six months. The testing program identified two definite sources of illicit connections, which have been investigated and repaired by the City. At the end of the pilot study a standard work plan was prepared for testing the rest of the City of Baltimore's storm drain system, which includes 26,950 storm drain manholes located over 49,183 acres.
