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.

Can risers be installed on any tank?

Most concrete and plastic tanks can accept risers. Your septic company will check the openings and choose matching parts.

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.

Do I need a permit to add risers?

Usually not, but some areas have rules. Check with the St. Louis County health department or ask your septic company.

Septic Tank Risers for Des Peres Homes

Many septic tanks in Des Peres sit a foot or more underground, which means digging every time the tank needs pumping or inspection. A riser brings the access opening up to ground level so the tank can be reached in minutes.

A local septic company that serves Des Peres and Kirkwood, Frontenac, Town and Country can install risers and secure lids, often during a regular pumping visit.

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.

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.

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.

Choosing risers and lids for a Des Peres tank

Risers come in plastic and concrete. Plastic risers are light, easy to cut to height and resist corrosion, which makes them the most common choice for existing tanks. Concrete risers are heavy and durable and are sometimes used on concrete tanks or where traffic is a concern. Lids should be secured with screws or a lock, and insulated lids are available for colder areas.

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.

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 Des Peres 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.

Why Des Peres homeowners add risers

Risers bring the tank lids up to ground level on Des Peres properties, so nobody has to dig to reach them. That saves time and money on every pumping and inspection. A secure lid also keeps children and pets safe. Most installs take a few hours and leave only a small patch of disturbed lawn.

Risers and lids for Des Peres weather

Where soils are rated very limited, as most mapped soils near Des Peres are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Des Peres averages about 43 inches of precipitation a year, so ask for sealed joints that keep rain and groundwater out. With about 1 months below freezing, an insulated lid can help protect the tank opening in winter.

Local conditions in Des Peres that affect septic riser and lid installation

Among the mapped soils within about two miles of central Des Peres, the USDA soil survey rates 96% as very limited for septic absorption fields, 4% 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.

Des Peres averages about 43 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 1 month a year, with January averaging 30°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
