06 Apr About Low Pressure Sewer Systems
Low Pressure Sewer Systems are a low-head pressure wastewater collection system, used as an alternative to gravity sewer.
A Low Pressure Sewer System consists of an interceptor tank and a chamber unit, which houses a small, submersible grinder or ejector pump. The tank is installed below ground somewhere on the homeowner’s property, much like a septic tank. The liquid in the tank is pumped automatically through a small pressure line that conveys it to a wastewater treatment plant.
WHO MAINTAINS THE LOW PRESSURE SYSTEM?
From the interceptor tank to the treatment plant, the system is maintained by your Homeowner’s Association or a Municipal Utility District. Any problems that arise with the interceptor tank, submersible pump and/or plumbing from the house to the property line are the responsibility of the homeowner.
IS THERE ANYTHING THAT SHOULD NOT GO DOWN THE DRAIN OR TOILETS?
Yes. Practice the “Three P’s” Poop, Paper & Pee. Nothing else should be flushed or washed down drains when flowing into a sewage grinder pump system.
Eliminating the following items will reduce emergency call-outs for malfunctioning pumps and floats and enhance their longevity.
- Sanitary hygiene products
- Dental floss
- Fibrous hand wipes/baby wipes/sanitary wipes
- Cooking grease or oil
- Large amounts of hair (i.e.: animal, etc…)
- Kitty litter
- Fish tank rocks
- Combustible liquids (i.e.: gasoline, paint thinner, etc…)
The sewage grinder pump has cutters that reduce waste volume so that it can be pumped into a low pressure system. The above items have a tendency to group together and clog and/or burn out the motor. Grit of any kind causes the cutters to wear prematurely.
