| DESCRIPTION: | |||||||||
| Approximately 1000' of 18" DIP pressure sewer to be replaced with a larger gravity sewer pipe to eliminate manhole surcharging which occurs just upstream of this section of pipe during peak flows. This section of pipe is part of the sewer interceptor which is located on Navy property upstream of the Marlay-Taylor WRF. Specifically, this section of pipe is located between Manholes 11 and 12 on the Contract 2-S construction plans. The interceptor sewer upstream of Manhole 12 is 30" RCP and downstream of Manhole 11 is a 27" RCP. It is expected that the replacement of this section of main will eliminate the current surcharging of the sewer during peak flows. | |||||||||
| PLANNING JUSTIFICATION: | |||||||||
| Built as part of Contract 2-S in the late 1960s, this particular section of interceptor sewer collects sewerage from the majority of the Lexington Park System as well as the entirety of Piney Point. Between Manholes 11 and 12 on this set of construction plans, there is a section of main which reduces to an 18" DIP pressure sewer for approximately 1000 feet. There is a 30" RCP sewer upstream of this point and a 27" RCP sewer downstream of this section of main. During peak flows, this section of pipe cannot handle the amount of flow going through and as a result the upstream manhole surcharges. Replacing this section of main with a larger size pipe will eliminate the surcharging problem, as well as the sanitary sewer overflows that have periodically occurred over the past year or so. This problem must be corrected as soon as possible to avoid additional Sanitary Sewer Overflows and potential water quality violations. | |||||||||
