Septic Tank Risers for Mattapoisett Homes
If your septic company has to dig up the lid every time they visit, a riser can pay for itself. Risers extend the tank openings to the surface and are capped with lids that lock.
Request a call and a company working in Mattapoisett will explain the options and install risers on your tank.
What a septic riser is
A riser is a short pipe or collar, usually plastic or concrete, that attaches to the tank opening and extends it to ground level. A lid on top, typically secured with screws or a lock, keeps it closed. Most tanks have at least two openings, and many benefit from a riser on each, plus one on the effluent filter.
Why homeowners add risers
Risers save time and money on every pumping and inspection because no digging is needed. They make it easy to check the filter, see problems early and get to the tank fast in an emergency. Many homeowners add them the first time a crew has to dig for buried lids.
Installing risers step by step
The crew finds the tank and uncovers each opening, cleans the top of the tank, then attaches the riser with sealant or fasteners so groundwater cannot leak in. The riser is cut to the right height, a lid is screwed on and the soil is backfilled. It is often done during a pumping visit.
Keeping riser lids safe
An open septic tank is dangerous because of gases and deep liquid. Riser lids should be screwed down or locked, rated for foot traffic, and replaced right away if they crack. Never leave a lid off unattended, and keep children and pets away while the tank is open.
What a riser job costs depends on
The price depends on how many openings get risers, how deep the tank is buried, whether plastic or concrete is used, and whether the job is done during a pumping visit. Deeper tanks need taller risers and more digging, which adds labor time.
What to ask about riser installation
Ask how many openings your tank has and which ones should get risers, what material they install, how the risers are sealed to the tank, and how the lids are secured. Ask whether combining the job with pumping lowers the total cost.
Choosing risers and lids for a Mattapoisett tank
Risers come in plastic and concrete. Plastic risers are light, easy to cut to height and resist corrosion, which makes them the most common choice for existing tanks. Concrete risers are heavy and durable and are sometimes used on concrete tanks or where traffic is a concern. Lids should be secured with screws or a lock, and insulated lids are available for colder areas.
After risers are installed
Once risers are in, pumping and inspection visits in Mattapoisett are quicker because the crew can open the tank without digging. Keep the lids visible and clear of mulch or soil, and check them now and then for cracks or loose screws. Note the location on a sketch of your property so future owners and contractors can find the tank easily.
Is your tank a good candidate
Most tanks can take risers, but the value depends on how deep the lids are and how often the tank is opened. Ask your Mattapoisett septic company how deep your lids sit, how much digging costs on each visit, and whether an effluent filter is installed. Those answers usually make the decision easy.
Making tanks easier to reach near Mattapoisett
If your service company has to dig to reach the tank every time, risers are worth asking about. Septic companies around Mattapoisett install them on most tank types, and the savings on future visits often cover the cost over time.
Risers and lids for Mattapoisett weather
Where soils are rated very limited, as most mapped soils near Mattapoisett are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. With about 45 inches of precipitation a year, a well-sealed riser matters. Poorly sealed joints can let groundwater into the tank.
