Septic Tank Risers for Benson 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 Benson will explain the options and install risers on your tank.
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 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.
A typical riser installation
Most riser jobs take a few hours. The tank openings are dug out, the riser is sealed to the tank, trimmed to sit at or just above grade, and a locking lid is installed. Doing it the same day as a pumping saves a second dig.
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 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.
Materials and options
Most homeowners in Benson choose plastic risers with a green or tan lid that blends into the lawn. Concrete risers suit some tanks and settings better. The key choices are the diameter to match your tank opening, the height needed to reach grade, and whether you want an insulated or traffic-rated lid.
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.
Why Benson homeowners add risers
Risers bring the tank lids up to ground level on Benson 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 Benson weather
Where soils are rated very limited, as most mapped soils near Benson are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Benson averages about 25 inches of precipitation a year, so ask for sealed joints that keep rain and groundwater out. With about 4 months below freezing, an insulated lid can help protect the tank opening in winter.
Local conditions in Benson that affect septic riser and lid installation
Among the mapped soils within about two miles of central Benson, the USDA soil survey rates 92% as very limited for septic absorption fields, 8% as somewhat limited and 0% as not limited. The most common drainage class is 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.
Benson averages about 25 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 4 months a year, with January averaging 12°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.

Septic Riser and Lid Installation questions in Benson
- 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 Swift County health department or ask your septic company.
