Septic Tank Risers for Lanark 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 Lanark will explain the options and install risers on your tank.

Why tanks are buried so deep

Older installations often placed lids well below the surface, sometimes to protect them from freezing or damage. That made sense at the time, but it means every pump-out starts with digging. Risers solve that without moving the tank.

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.

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.

Getting the most from your risers

Risers make it easy to check the effluent filter between pumpings. Ask your septic company to show you how to open the lid safely and what to look for. Many Lanark homeowners also find it easier to keep a regular pumping schedule once access is simple.

Signs a Lanark tank would benefit from risers

Risers are worth considering if every pumping visit in Lanark 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.

Lanark averages about 38 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 21°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
