Septic Tank Riser Installation
Bring your septic tank access to grade level with professional riser installation from a trusted local team.
5 Highlights on Septic Tank Riser Installation
- Grade level access every time. We install stackable polyethylene and concrete riser rings that bring your septic tank manhole from buried depth to flush mounted at the surface, so you never dig again for pumping or inspection.
- Watertight seal guaranteed. Every riser ring and adapter ring gets bedded with butyl sealant and secured with stainless steel screws to prevent groundwater infiltration and effluent leaks at every joint.
- Compatible with all tank types. Our technicians retrofit risers onto precast concrete tanks, fiberglass tanks, and polyethylene tanks using the correct adapter ring and collar for a load bearing, sealed fit.
- Safety lids included. Each installation comes with a locking safety lid rated for foot traffic or vehicle traffic depending on your property layout, keeping children and animals safe from open access ports.
- Permits and code compliance. We pull any required permits through your local health department and confirm that every riser installation meets current setback and sanitary code requirements before backfilling.
Why Choose Our Septic Tank Riser Installation
Septic tank riser installation is one of the best upgrades a homeowner can make to a conventional septic system. A-1 Bill Gibson Septic Service has installed risers on residential and commercial tanks across the region for years. We know the work inside and out.
Our installers are qualified, certified technicians who assess each tank before selecting the right riser system. Not every tank takes the same approach. Concrete tanks need a different adapter ring than polyethylene tanks. Corrugated or damaged tank openings require custom fitting. We measure, inspect, and confirm compatibility before we cut or drill anything.
We carry a full inventory of riser rings, extension rings, adapter rings, and locking lids on every truck. That means most installations finish in a single visit. No waiting on parts. No return trips.
Our pricing is upfront. We quote the job after locating and uncovering your tank, and the number doesn’t change. You get a written guarantee on the watertight seal and the structural integrity of the riser assembly.
Other pumpers skip the details. We don’t. Every joint gets butyl sealant. Every screw is stainless steel. Every lid locks. A-1 Bill Gibson Septic Service treats your riser installation like it’s going on our own property, because our reputation depends on it.
Signs You Need Septic Tank Riser Installation
Septic tank riser installation solves real problems that homeowners deal with every pumping cycle. Here are five signs you need one.
You dig up your yard every time the tank needs pumping: If your septic tank lid sits 12 to 24 inches underground, your pumper has to excavate the area with a shovel or backhoe each visit. That tears up grass, landscaping, and irrigation lines. A riser brings the access port to grade level permanently.
Your concrete lid is cracked or deteriorating: Old concrete lids lose their watertight seal over time. Cracks let rainwater and surface runoff pour into the tank, overloading the drain field. A new riser assembly with a sealed plastic lid fixes the problem and prevents future infiltration.
You can’t locate your tank without a probe rod: Buried tanks with no visible marker are hard to find. Pumpers charge extra to locate and uncover them. A flush mounted riser lid marks the exact spot and cuts your service time in half.
Your tank has no inspection port: Older septic systems sometimes lack a dedicated inspection port. Installing a riser with a removable lid gives your technician direct visual access to the inlet baffle, outlet baffle, scum layer, and sludge layer without heavy excavation.
You’re selling your home and need a septic inspection: Inspectors require access to the tank. A buried lid with no riser means you’ll pay for excavation just to get the inspection done. Installing a riser before listing saves money and speeds up the certification process.
Our Septic Tank Riser Installation Process
Septic tank riser installation is a straightforward process when a qualified technician handles it. Here’s how A-1 Bill Gibson Septic Service completes every job.
Step 1: Locate the tank. We use a probe rod, sewer tape, or electronic locator to find the buried septic tank and mark the access point on the surface.
Step 2: Excavate to the lid. We dig down to the existing concrete lid or manhole cover using a shovel or compact excavator, depending on depth and soil conditions.
Step 3: Remove the old lid. We pull the original concrete lid or damaged cover off the tank opening and inspect the rim for cracks, corrosion, or structural issues.
Step 4: Fit the adapter ring. We set a flat adapter ring or collar onto the tank opening, bedding it in butyl sealant to create a watertight bond between the tank and the first riser ring.
Step 5: Stack and secure riser rings. We stack polyethylene or concrete riser rings to reach grade level. Each ring gets sealed with butyl sealant and fastened with stainless steel screws.
Step 6: Install the lid. We attach a locking safety lid on top, confirm the seal, and verify the assembly is level and flush mounted with the surrounding grade.
Step 7: Backfill and grade. We backfill compacted soil around the riser, grade the surface for proper drainage away from the lid, and clean up the work area.

FAQs About Septic Tank Riser Installation
What is a septic tank riser?
A septic tank riser is a vertical pipe or series of stackable rings that extend the tank’s access opening from its buried depth up to grade level. The riser sits on top of the tank and gets capped with a sealed, locking lid so pumpers and inspectors can reach the tank without digging.
When should I install a riser on my septic tank?
Install a riser any time your tank lid sits more than six inches below the surface. The best time is during a scheduled pump out, since the tank is already uncovered and the pumper can assess the opening for proper adapter ring sizing.
Why does a septic tank riser need to be watertight?
Rainwater and surface runoff will flow into any gap between the riser and the tank. That extra water overloads the drain field, saturates the soil, and can cause the system to back up or fail. Butyl sealant and stainless steel screws keep every joint sealed against infiltration.
How long does septic tank riser installation take?
Most residential installations take two to four hours. Locating and excavating the tank accounts for most of that time. Stacking the riser rings, sealing the joints, and attaching the lid goes quickly once the tank opening is exposed and prepped.
Can you install a riser on an old concrete septic tank?
Yes. We retrofit risers onto concrete tanks regularly. The adapter ring sits flat on the concrete rim and bonds with butyl sealant. If the rim is cracked or uneven, we repair or grind it level before setting the adapter.
Does a septic tank riser require a permit?
Some jurisdictions require a permit for any work on a septic system, including riser installation. A-1 Bill Gibson Septic Service checks with your local health department and pulls any required permits before starting the job.
