Septic Tank Risers for Thompson Homes

Many septic tanks in Thompson 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 Thompson and Grand Forks, East Grand Forks can install risers and secure lids, often during a regular pumping visit.

How risers and lids work

The riser bonds or bolts to the tank opening and is sealed to keep groundwater and soil out. It is cut to reach just at or above grade. The lid sits on top so the tank can be opened by hand without a shovel. Some lids are insulated for cold weather.

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.

Installing risers step by step

The crew finds the tank and uncovers each opening, cleans the top of the tank, then attaches the riser with sealant or fasteners so groundwater cannot leak in. The riser is cut to the right height, a lid is screwed on and the soil is backfilled. It is often done during a pumping visit.

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.

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.

Choosing risers and lids for a Thompson 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 Thompson 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 Thompson

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

Risers and lids for Thompson weather

Where soils are rated very limited, as most mapped soils near Thompson are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Thompson averages about 23 inches of precipitation a year, so ask for sealed joints that keep rain and groundwater out. With about 5 months below freezing, an insulated lid can help protect the tank opening in winter.

Local conditions in Thompson that affect septic riser and lid installation

Among the mapped soils within about two miles of central Thompson, the USDA soil survey rates 91% as very limited for septic absorption fields, 9% as somewhat limited and 0% as not limited. The most common drainage class is somewhat poorly 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.

Thompson averages about 23 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 5 months a year, with January averaging 7°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
