STOP before you pour grease down the sink drain.  Grease builds up inside the sewer
pipe in your house as well as the sewer lateral leading from your house.  This can block your sewer and cause a backup in your house.

Construction Update - Wastewater Treatment Plant:
The Authority has completed the installation of two (2) post-aeration tanks and a concrete
pad for an air blower along with underground piping, air diffusers and dissolved oxygen meters.  This will increase the amount of dissolved oxygen in the effluent prior to its discharge to the Schuylkill River in order to comply with the new dissolved oxygen limits in the permit issued by the Pennsylvania Department of Environmental Protection for the treatment facility.

The Authority has undertaken the rehabilitation of one of the four digesters at the wastewater treatment plant.  The digesters are cylindrical shaped containers (visible in the above aerial view of the plant) that are used to reduce the mass of the sludge after it is removed from the wastewater and to convert it into a non-hazardous form by heating and mixing the sludge.  The rehabilitation will consist of two parts.  The first contract will cover the removal of all of the remaining residuals in the digester followed by the cleaning of the digester.  Afterwards the inside of the digester will be inspected to determine if any piping or valves need to be replaced.  This work has been completed.  The second contract will include the installation of a new mixing device and the repair/replacement of any appurtenances.  This work is expected to be finished by the end of 2018 and is estimated to cost $1,500,000.

Construction Update - Sanitary Sewers:

The Authority has recently completed several contracts for sewer improvements in an effort to comply with the Consent Order and Agreement signed with the Pennsylvania Department of Environmental Protection (see discussion under "About NMWA" below).

In June 2014 the Authority awarded Contract No. 1 – Sewer Pipe Rehabilitation Project in the amount of $527,777.  It consisted of 42 open-cut repairs of various sections of sanitary sewer pipe throughout the Municipality of Norristown that are either crushed or severely cracked. 

The second phase of the Sewer Rehabilitation Project, Contract No. 2, was awarded in July 2014 in the amount of $684,218.  The work consisted of the lining of approximately 8,400 linear feet of sewer pipe in 44 locations throughout the Municipality of Norristown as well as the leak repair and lining of 10 sanitary sewer manholes.  This contract was financed in part by a grant from the Pennsylvania Department of Commerce and Economic Development.

During the summer of 2016, the Authority replaced the sanitary sewer serving the south side of the 300 block of Warren Street and extended the sanitary sewer approximately 300 feet in the 1800 block of Chain Street.   The former will eliminate sections of damaged pipe while the latter will enable several properties that are currently on a septic system to connect to public sewers.  The total cost of both projects was approximately $250,000.

The Authority awarded a contract in March 2018 in the amount of $329,390 for lining and rehabilitation of approximately 125 manholes throughout the Municipality of Norristown to help reduce the amount of rainwater that enters the sanitarty sewer system. The contract is financed in part by a grant from Pennsylvania Department of Commerce and Economic Development.


About the NMWA
The Norristown Municipal Waste Authority was formed in 1993 for the purpose of operating the municipality's sewer system.  The Authority is governed by a five member Board appointed by the Municipal Council.  Each board member is appointed for a five-year term.
The Authority owns and operates the wastewater treatment plant and the collection sewers of the Municipality.  The wastewater treatment facility is located at 368 East Washington Street and discharges effluent to the Schuylkill River.  The plant serves both the Municipality and the Township of West Norriton.

In August 2008 the Authority signed a Consent Order and Agreement (CO&A) Amendment with the Pennsylvania Department of Environmental Protection. The CO&A Amendment broke the collection system into geographic quadrants or "Quads" and established time frames for the investigation, rehabilitation and flow monitoring work to be done in each Quad with a goal of reducing the amount of rainwater or infiltration/inflow ("I/I") entering the collection system and ultimately the wastewatre treatment plant (please review the information presented under the Infiltration and Inflow tab.)  The CO&A Amendment mandates the completion of the work and the issuance of a final report by Febuary 2019 documenting the amount of I/I removed from the collection system.


The work involves the following in each Quad:


  • Televising of the majority of the sanitary sewer mains to determine the condition of the sewer.  This has been completed.
  • Repair/replacement of sanitary sewer mains in critical condition.  This has been completed in Quad 1.
  • Rehabilitation of manholes, including manhole inserts to prevent rainwater from entering the manhole, new manhole covers, and the replacement of manhole frames and covers, as needed.  This has been completed in Quad 1.
  • Installation of inserts in the cleanouts of the sewer pipe servicing individual properties.  This work is ongoing in each Quad.
