Low Pressure Sewer System a network of small diameter low pressure piping and appurtenances, located within the public right-of-ways and/or utility easements, serving multiple residential grinder pumps and discharging to the existing gravity sewer system. All Residential Grinder Pumps, including appurtenant piping and controls contained within the property served, shall be owned and operated by the respective property owner(s). Low Pressure Sewer System shall be owned and operated by Limerick Township, except for systems located on private property. At no time will Limerick Township assume ownership or be responsible for the operation or maintenance of any Residential Grinder Pump, regardless of whether it is connected to a Low Pressure Sewer System or to gravity sewer system. Grinder pump systems other than those described above, such as grinder pump stations serving large commercial properties or multiple housing units, are not covered by these guidelines and will be considered on a case-by-case basis. Guidance regarding such grinder pump stations is contained in the Limerick Township Sewer Department Pumping Station Guidelines. These Guidelines are not rigid requirements. The Guidelines are subject to revision and updating and, therefore, Developers should not necessarily rely on a particular version which they might have, but, rather, should first confirm with the Township that the version in their possession is the most recent as adopted by the Township. In addition to these Guidelines, the PADEP has design standards for low pressure sewers, which are included in the publication entitled “Domestic Wastewater Facilities Manual” which also should be taken into consideration. Depending on the scope of the installation, an application may need to be submitted to the PADEP in order to obtain a Water Quality Management Permit prior to construction of a low pressure sewer system.
