Low Pressure Sewer
What is Low Pressure Sewer (LPS)?
Low Pressure Sewer (LPS) is a low-head pressure wastewater collection and treatment system, an alternative to gravity sewer or a septic tank. An LPS system consists of an interceptor tank and a chamber unit, which houses a small, submersible electrical pump. The tank is installed below ground, much like a septic tank. Substantial organic waste treatment is provided energy-free in the interceptor tank. The liquid in the tank, or effluent, is pumped automatically through a small pressure line that transports it to a wastewater plant for treatment. The system was approved by the Florida Department of Environmental Protection in June 1981 and is commonly used today.
Will I hear the pump run?
No. The pump is a high-quality submersible pump. Every time you use approximately 100 to 150 gallons of water, the pump will automatically turn on and shut off. Based on normal water usage for a family of two, the pump will run for about two to three hours per month.
Who maintains the LPS system?
From the interceptor tank to the treatment plant, the system is maintained by Charlotte County Utilities, including all parts and labor costs. This includes pumping out the tank if solids build up. Do not call a private company for this service, as you will likely incur all charges. Any house plumbing problems are the cost and repair responsibility of the customer.
A removable patio stone will be placed over the fiberglass lid of the sump pump to allow for easy maintenance, inspection and repair. Please refrain from putting lawn ornaments, potted plants or landscaping elements weighing more than 50 pounds on top of this stone. CCU is not responsible for damage or breakage of any ornament or object that restricts accessibility.
Do not allow heavy vehicles or machinery to drive over the area of the LPS tank and do not plant any large plants or trees within a 10-foot area around the LPS patio stone cover or in the area of your house drainage clean-out pipe to eliminate any potential root problems in your lines or in the collection system.
What happens if there is a power failure?
If the power is off, the pump will not operate. However, there is a reserve capacity in the interceptor tank which allows for approximately eight hours of normal use (excluding uses such as running a washing machine and taking a bath) before you will experience any difficulty. Should you experience a power failure, please record the date, time and duration, if known, and report this information promptly to CCU.
Is there anything I should not put down the drain?
To protect the LPS systems biological process and to help prevent house plumbing lines from clogging, do not dispose of the following items through the drains or toilets:
Plastic or rubber of any kind
Feminine hygiene products
Cigarette butts (filters will not decompose)
Greases and cooking oils of all types
Coffee grounds and other inorganic materials
Excessive amounts of non-dissolving tissue paper or paper towels
Excessive use of laundry detergent or soaps
Human or pet hair
Cloth of any kind
Please note: If any of the above items are found to be responsible for LPS system failure, you will be charged for time and materials needed to make repairs.
If I have a problem with my LPS system, what should I do?
There is a warning light and audible alarm on each installation. The alarm will sound as soon as the water level in the pump chamber rises above the normal level. Push the alarm silence button and call CCU immediately. For any problems or questions regarding your system, please call CCU at (941) 764-4300 or 1-800-524-3494, seven days a week, 24 hours per day. Every effort will be made to provide you prompt, courteous and effective service.
If the alarm sounds, how long before the system backs up?
It depends on your usage. The system will usually take an additional 150 gallons of wastewater, but you should limit water usage and call CCU as soon as possible.
Is it possible for the system to overflow without the alarm going off?
Yes, it is possible. A float or another part of the alarm system could malfunction and in some cases may have shut off power. Call CCU for emergency service.
