Septic Tank Risers for Flandreau 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 Flandreau 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.
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.
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.
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.
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.
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.
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 Flandreau tank would benefit from risers
Risers are worth considering if every pumping visit in Flandreau 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 Flandreau yard
Riser lids for Flandreau 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 Flandreau weather
Where soils are rated very limited, as most mapped soils near Flandreau are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Flandreau averages about 26 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 Flandreau that affect septic riser and lid installation
Among the mapped soils within about two miles of central Flandreau, the USDA soil survey rates 85% as very limited for septic absorption fields, 15% 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.
Flandreau averages about 26 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 16°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
