Septic Tank Risers for Mattoon 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 Coles County can add risers to most existing tanks.
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 Mattoon 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 lids secure
A secure lid is a safety requirement, not an option. Check lids once in a while for cracks or loose screws. If a lid is damaged, cover the opening and call for a replacement.
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.
Getting the right fit
Tank openings vary in size and shape, so your installer will measure before choosing parts. The riser must seal tightly to the tank so groundwater stays out, and the lid must lock so it cannot be opened by children or pets. Ask your Mattoon septic company which options they recommend for your tank and why.
Living with risers
With risers in place, future pumping and inspections are faster and cleaner. Keep the lids visible, do not cover them with mulch or landscaping, and check every so often that the screws are tight and the lids are not cracked.
Signs your tank needs risers
If lids are buried, if the crew has to probe the yard to find the tank, or if past visits left holes in the lawn, risers will help. They also make sense if your system has a filter that should be checked often.
Risers and routine service in Mattoon
Once risers are in, a Mattoon septic company can open the tank in minutes. That makes it easier to keep a regular pumping schedule and to check the baffles and filter each time. Some homeowners add a riser over the outlet filter too, so it can be cleaned between pumpings.
Risers and lids for Mattoon weather
Where soils are rated very limited, as most mapped soils near Mattoon are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Mattoon averages about 43 inches of precipitation a year, so ask for sealed joints that keep rain and groundwater out. With about 2 months below freezing, an insulated lid can help protect the tank opening in winter.
Local conditions in Mattoon that affect septic riser and lid installation
Among the mapped soils within about two miles of central Mattoon, the USDA soil survey rates 100% as very limited for septic absorption fields, 0% as somewhat limited and 0% as not limited. The most common drainage class is well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.
Mattoon averages about 43 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 2 months a year, with January averaging 27°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
