Septic Riser and Lid Installation in Hillsdale, MO

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 Hillsdale 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.

What to expect on installation day

Most riser installations take a few hours. The tank is often pumped at the same time so the crew can inspect it while the openings are exposed. Expect some digging around the lids, which is backfilled when the job is done.

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.

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.

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.

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 Hillsdale 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.
