NSTMA SEWER SYSTEM
The NSTMA Sanitary Sewer System serves roughly 5,500
customers in the Township. The Sanitary Sewer System consists
of ten (10) pumping stations and one (1) 99,000 gallons per day
sewage treatment plant.
NORTH STRABANE TOWNSHIP MUNICIPAL AUTHORITY
TOWNSHIP COMPREHENSIVE SEWER PROJECT
NSTMA, has authorized the final phase of the Linden Creek
Watershed Sewer System to alleviate the pollution problems in
Little Chartiers Creek and to preserve the natural integrity of this
high quality trout stream.
Currently, all unsewered areas adjacent to Linden Creek utilize
some type of on-lot sewage system (septic tank, leach field /
drain field, or sand mound). A high percentage of these on-lot
systems are malfunctioning and contributing to the pollution
of the Linden Creek watershed. The watershed has an on-lot
failure rate of 70-90 percent. The proposed gravity sewers would
eliminate the majority of these on-lot septic systems and also be
capable of supporting future growth in all areas of the watershed.
NSTMA, in compliance with the Township’s Act 537 Plan and
Federal Clean Streams regulations, authorized the construction
of these projects. The gravity sewer extensions will discharge
into existing gravity sewers in the Township, which convey
sewage into NSTMA’s Route 19 Pump Station for treatment at
the Canonsburg Houston Joint Authority (CHJA) Wastewater
Treatment Plant.
NSTMA, with the assistance of the Township, has taken
advantage of low interest rates in 2014 through the issuance of
$8,800,000 in revenue bonds and has re-financed these bonds in
2019 for a substantial savings to our residents to fund the current
and future sanitary sewer projects listed below.

Christy/Linn Road Sewer Extension Project is located along
Christy/Linnwood Road in the upper portions of Christy/
Linnwood Road areas. The service area will initially include
55 homes/businesses at an estimated cost of $1,400,000.
The scope of this project will be based on the availability of
residual bond funds.
n 84 Pump Station/Forcemain Sewer Project: The 84

Route 136 in the Township. This project will replace the
existing sewage treatment plant with a pump station and
forcemain. This project will serve the entire 84 Watershed
area at an estimated cost of $900,000. The design and
permitting for this project is currently under way and the
scope of this project will also be based on the availability of
residual bond funds.
n Racetrack Road Siphon Upgrade Project: The Racetrack
Road Siphon Upgrade Project is located along Racetrack
Road. This siphon discharges into the CHJA Interceptor for
treatment at the CHJA Wastewater Treatment Plant. The
Racetrack Road Siphon Upgrade Project will replace the
existing undersized siphon and provide for additional
capacity in the service area. The project will serve the
entire Racetrack Road Watershed area at an estimated cost
of $575,000. The design and permitting for this project is
currently underway, with construction to start in the Summer
of 2020.
