Septic Tank Risers for Dunbar 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 Dunbar will explain the options and install risers on your tank.

What risers do for a septic tank

Risers extend the tank openings to ground level. Instead of searching for and digging up buried lids at every service visit, the crew simply unscrews a lid at the surface. Most risers are plastic, though concrete versions are also used, and each opening on the tank can have its own riser.

Why homeowners install risers

Easier access encourages regular maintenance, which is the best protection for a septic system. Risers also mark the tank location clearly, so it is not lost or damaged during future projects on your Dunbar property.

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.

Riser safety

Septic tanks contain gases and deep liquid, so lids must stay secured. Use lids with screws or locks, replace cracked lids promptly and never leave an opening uncovered. Keep vehicles off riser lids unless they are rated for traffic.

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.

Choosing a riser installer

Look for a company that seals risers properly to keep groundwater out and uses secure lids. Experience with tanks common around Dunbar and South Charleston, St. Albans, Nitro helps them match the right parts to your tank.

Plastic or concrete risers

Plastic risers are lightweight, easy to trim to height and do not corrode, so they suit most existing tanks. Concrete risers are heavy and durable but harder to install and can let in water if joints are not sealed well. Your septic company can recommend the right option for your tank.

After the risers go in

Make a note of where the lids are for future owners and service crews. Mowing around them is easy if they sit flush, and they make it simple to check the effluent filter or water level. Report any loose or damaged lid to your septic company.

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 Dunbar 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.
