Do septic risers let water into the tank?

Not when installed correctly. Joints are sealed to keep groundwater and soil out. Poorly sealed risers can leak, which is why installation quality matters.

Will risers make my yard look worse?

Lids sit at or just above ground level and are usually green or tan. Many homeowners find them less noticeable than the patches left by repeated digging.

Can I mow over a septic riser?

Most lids sit at grade so you can mow around them easily. Avoid driving heavy equipment over them unless they are traffic rated.

Is SepticTank.com the company that installs risers?

No. SepticTank.com connects you with an independent local septic company that serves Mokena. That company does the work and sets its own prices.

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

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.

Benefits of adding risers

Risers cut the time and cost of every pumping and inspection, since no digging is needed. They make it easy to check the effluent filter, spot problems early and show inspectors the tank during a home sale. They also protect your lawn from repeated digging.

How riser installation works

The crew locates and uncovers the tank openings, cleans the surfaces, attaches the risers with adhesive or fasteners, seals the joints and cuts the risers to height. After the lids are installed and secured, the soil is backfilled around them. Installing risers during a pumping visit saves a separate trip.

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.

Is a riser worth it

For most homes with buried lids, yes. The savings from not digging on every visit, plus easier inspections, often cover the cost over a few pumpings. Ask your septic company to compare the cost with what you pay for digging now.

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 Mokena and Frankfort, Orland Hills, Tinley Park 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.

Getting the most from your risers

Risers make it easy to check the effluent filter between pumpings. Ask your septic company to show you how to open the lid safely and what to look for. Many Mokena homeowners also find it easier to keep a regular pumping schedule once access is simple.

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 Mokena 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 Mokena

If your service company has to dig to reach the tank every time, risers are worth asking about. Septic companies around Mokena install them on most tank types, and the savings on future visits often cover the cost over time.

Risers and lids for Mokena weather

Where soils are rated very limited, as most mapped soils near Mokena are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Mokena averages about 39 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 Mokena that affect septic riser and lid installation

Among the mapped soils within about two miles of central Mokena, 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 moderately 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.

Mokena averages about 39 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with January averaging 23°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
