Septic Tank Risers for Dwight 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 Dwight will explain the options and install risers on your tank.
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.
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 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.
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 Dwight and Gardner, Coal City, Diamond helps them match the right parts to your tank.
Choosing risers and lids for a Dwight 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 Dwight 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 Dwight
If your service company has to dig to reach the tank every time, risers are worth asking about. Septic companies around Dwight install them on most tank types, and the savings on future visits often cover the cost over time.
Risers and lids for Dwight weather
Where soils are rated very limited, as most mapped soils near Dwight are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. Dwight 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 Dwight that affect septic riser and lid installation
Among the mapped soils within about two miles of central Dwight, 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 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.
Dwight averages about 39 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 24°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
