Do septic risers let water into the tank?

Not when installed correctly. Joints are sealed to keep groundwater and soil out. Poorly sealed risers can leak, which is why installation quality matters.

Will risers make my yard look worse?

Lids sit at or just above ground level and are usually green or tan. Many homeowners find them less noticeable than the patches left by repeated digging.

Can I mow over a septic riser?

Most lids sit at grade so you can mow around them easily. Avoid driving heavy equipment over them unless they are traffic rated.

Is SepticTank.com the company that installs risers?

No. SepticTank.com connects you with an independent local septic company that serves St. Ignace. That company does the work and sets its own prices.

Septic Tank Risers for St. Ignace 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 Mackinac 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.

Installing risers on an existing tank

Nearly any concrete or plastic tank can accept risers. The installer matches the riser to the opening size and material, seals it to keep water out, and secures the lid. Lids should always be fastened so children and pets cannot open them.

Keeping riser lids safe

An open septic tank is dangerous because of gases and deep liquid. Riser lids should be screwed down or locked, rated for foot traffic, and replaced right away if they crack. Never leave a lid off unattended, and keep children and pets away while the tank is open.

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.

Picking lids for St. Ignace 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.

After risers are installed

Once risers are in, pumping and inspection visits in St. Ignace are quicker because the crew can open the tank without digging. Keep the lids visible and clear of mulch or soil, and check them now and then for cracks or loose screws. Note the location on a sketch of your property so future owners and contractors can find the tank easily.

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 St. Ignace 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.
