NOTICE:

For Blockages please notify the Long Hill Township Police Department at 908-647-1800 

The Township manages wastewater (sewage) at a Treatment Plant built in the 1930s and enlarged in 1975, 1984 and 1991.  The plant is now licensed to process 900,000 gallons of wastewater per day, and is currently operating at about 85% of that permitted limit. 

Approximately 88% of the town's residential housing units and nearly 100% of the commercial/industrial sites are connected to the sewer system.  The Master Plan (1995) discourages further expansion of the sewer treatment plant and sewer line extensions, except to reach areas of significant septic dysfunction.

The sewage treatment plant operates under Federal and State regulations for a plant located on "F3 waters".  That means the discharge has got to be clean enough that it does not harm the fish life in the Passaic River.

Inflow & Infiltration: I&I

Inflow is water discharged into a sewer system and service connections from such sources as, but not limited to, roof leaders, cellars (sump pumps), yard and area drains, foundation drains, cooling water discharges,drains from springs and swampy areas, around manhole covers, cross connections from storm and combined sewer systems, storm waters, surface runoff, street wash waters or drainage.  Inflow differs from infiltration in that it is a direct discharge into the sewer system rather than a leak in the system itself.

Infiltration is the seepage of ground water into the sewer system, including service connections.  Seepage frequently occurs through defective or cracked pipes, pipe joints, connections or manhole walls.

You Can Help!

Sump Pumps:

If you have a sump pump in you basement, check to see if it is connected to your sanitary line.  If so, have it redirected (hard piped, pvc ok) or discharge out to either surface discharge or to your leader drain system. Leader drains should not be connected to the sanitary system. 

If you are uncertain of how your connection is made, contact the Wastewater Division at 908-647-0789, and we will be happy to check it for you and give you advice on how to make the correction if needed.

Cleanout Caps:

Service lateral cleanouts are usually located on your property prior to the sewer main.  The cleanout caps are of either brass or pvc. These caps are frequently damaged by landscapers and go undetected by the homeowner.  Open cleanouts are a means of inflow through the service connection.  They are also vulnerable to allow sticks, leaves and other unwanted debris to enter your service connection and cause blockages.

Periodically inspect your cleanout to see if it is intact.  If not, please have it repaired.  Repairs are usually inexpensive and can be made yourself or by your local plumber.

Funding for Waste Water Services:

Residents pay for Sewage Treatment through their Annual Sewer User Fees.

Please do not put disposable diapers, baby wipes, paper towels and feminine hygiene products or plastic applicators into the sewer system.  They do not dissolve or break down, they clog up the pumps, and they have to be removed during processing.  This results in added cost to the Township.  Please follow product packaging for proper disposal.
