Septic Tank Risers for Garretson Homes

Easy access makes septic care simpler. Risers and lids let you and your septic company check the tank without digging up the yard, and they make it far easier to find the tank later.

Companies that work across Minnehaha County can add risers to most existing tanks.

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.

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.

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 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.

Picking lids for Garretson risers

Lids should be secured with screws or a lock and strong enough to walk on. Green lids blend into a lawn, while lids that sit slightly above grade are easier to find and keep surface water out. Ask your installer what works best for your yard.

Caring for lids over time

Sun and mowers can wear lids over the years. Replace any lid that cracks or no longer locks, and keep heavy equipment away unless the lid is rated for traffic. A secure lid on a Garretson property protects people and pets and keeps rain out of the tank.

Good times to add risers

The best time to add risers is during a scheduled pumping, when the lids are already dug up. They are also worth adding after buying a home if no one knows where the lids are, or if your service company charges extra to dig.

Garretson averages about 29 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 17°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
