News & Events

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.

Construction Update - Sanitary Sewers:

In June 2014 the Authority awarded Contract No. 1 – Sewer Pipe Rehabilitation Project in the amount of $527,777.  The Project is being undertaken in compliance with the Consent Order and Agreement signed with the Pennsylvania Department of Environmental Resources (see discussion below under About the NMWA).  It consists of 42 open-cut repairs of various sections of sanitary sewer pipe throughout the Municipality of Norristown that are either crushed or severely cracked.  This work should help the Authority to reduce the amount of rainwater that enters the sanitary sewer system.  The Project is expected to start by the end of October and should be completed within six months.  For a list of the streets impacted by the construction click here.  When the contractor is working in the street, there may be some minimal disruption. 


The second phase of the Sewer Rehabilitation Project, Contract No. 2, was awarded in July 2014 in the amount of $684,218.  The work consists 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.  Unlike the repairs to be taken in Contract No. 1, the sewer lining does not require the dig-up of the street because the sewer pipe is not severely damaged and therefore does not need to be replaced.  Construction should start in November 2014 and should be completed within six months.  This contract is financed in part by a grant from the Commonwealth of Pennsylvania, Commonwealth Financing Authority.


 


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 Board appointed by the Municipal Council 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.
