<<< Back to Lake Quivira Sanitary Sewer Repair - 2011

CIPP lining rehabilitation will begin in late November/early December.

As part of the current sanitary sewer rehabilitation efforts, Johnson County Wastewater has contracted with SAK Construction to begin rehabilitating sanitary sewer mains throughout the community beginning in late November/early December using the trenchless cured-in-place pipe (CIPP) lining method.  CIPP lining is a method of trenchless pipe rehabilitation in which a resin-saturated polyester felt tube is installed in the sewer pipe through an existing manhole.  The resin in the  tube is then cured (hardened) using steam or hot water.  The service laterals are then opened using a robotically-controlled cutting device.

If your sewer service will be interrupted due to this work, you will be notified via door hanger prior to the service interruption.  Please note the following if you are notified of potential service interruption:

• A plume of steam exhaust may be noticed during the sewer lining work.  The steam is used during the lining process.  During colder weather, the steam is visible and may resemble smoke.  As with all construction, please keep a safe distance from the work to avoid the steam and any possibility of burns from the heat.
• Because your service connection will be temporarily closed off for a few hours during the lining process, please limit activities that use a large volume of water such as running dishwashers, washing machines, and showers.  Minimal restroom usage is acceptable.  Your service lateral will be fully opened and back in service by the end of each work day.
• If you have a sump pump connected to your sewer lateral, please unplug it during the lining process.
• To reduce the potential for chemical odors, please pour some water into your basement floor drain(s).  This is a good practice on a regular basis to prevent sewer gasses from entering your home.  If you do detect an odor, open your windows and/or turn on a fan to help ventilate your home.  The level of airborne chemical for the lining process does not pose a health risk.

Construction sites can be dangerous and your safety is extremely important to us.  We realize that construction can create some inconveniences and annoyances, and we are doing everything possible to keep these to a minimum during this project.  Thanks again for your patience.
