Septic Tank Risers for Hattiesburg Homes
Easy access makes septic care simpler. Risers and lids let you and your septic company check the tank without digging up the yard, and they make it far easier to find the tank later.
Companies that work across Forrest County can add risers to most existing tanks.
Why tanks are buried so deep
Older installations often placed lids well below the surface, sometimes to protect them from freezing or damage. That made sense at the time, but it means every pump-out starts with digging. Risers solve that without moving the tank.
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 Hattiesburg property.
Installing risers on an existing tank
Nearly any concrete or plastic tank can accept risers. The installer matches the riser to the opening size and material, seals it to keep water out, and secures the lid. Lids should always be fastened so children and pets cannot open them.
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 affects riser cost
Price depends on the number of openings, how deep the tank is, the riser material and whether the job is combined with pumping. Deeper tanks need taller risers and more digging. Insulated or traffic-rated lids cost more.
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.
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.
Good times to add risers
The best time to add risers is during a scheduled pumping, when the lids are already dug up. They are also worth adding after buying a home if no one knows where the lids are, or if your service company charges extra to dig.

Risers and lids for Hattiesburg weather
Where soils are rated very limited, as most mapped soils near Hattiesburg are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. With about 60 inches of precipitation a year, a well-sealed riser matters. Poorly sealed joints can let groundwater into the tank.
