Septic Tank Risers for Mahomet 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 Mahomet 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.

What to expect on installation day

Most riser installations take a few hours. The tank is often pumped at the same time so the crew can inspect it while the openings are exposed. Expect some digging around the lids, which is backfilled when the job is done.

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 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.

Questions to ask about risers

Ask how many openings your tank has, which should get risers, what material they use, and whether lids are secured with screws or locks. Ask if they can install during your next pumping.

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 Mahomet septic company which options they recommend for your tank and why.

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.

Signs a Mahomet tank would benefit from risers

Risers are worth considering if every pumping visit in Mahomet starts with digging. The same goes if nobody is sure where the lids are, or if the crew charges extra to uncover a deep tank. They also help when you want to check the effluent filter yourself or are getting ready to sell and expect an inspection. Landscaping that has made the tank harder to reach is another good reason.

Choosing riser lids for a Mahomet yard

Riser lids for Mahomet homes come in green or brown plastic and in concrete. Plastic is lighter and easier to open, while concrete is heavier and harder to move. Either way, the lid should lock or screw down. Ask the installer to seal the joint so groundwater cannot leak into the tank.

Risers and lids for Mahomet weather

Where soils are rated very limited, as most mapped soils near Mahomet are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Mahomet averages about 41 inches of precipitation a year, so ask for sealed joints that keep rain and groundwater out. With about 3 months below freezing, an insulated lid can help protect the tank opening in winter.

Local conditions in Mahomet that affect septic riser and lid installation

Among the mapped soils within about two miles of central Mahomet, the USDA soil survey rates 98% as very limited for septic absorption fields, 2% 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.

Mahomet averages about 41 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with January averaging 26°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
