Septic Tank Risers for Gresham 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 Multnomah 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.

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.

Installing risers step by step

The crew finds the tank and uncovers each opening, cleans the top of the tank, then attaches the riser with sealant or fasteners so groundwater cannot leak in. The riser is cut to the right height, a lid is screwed on and the soil is backfilled. It is often done during a pumping visit.

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.

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.

Materials and options

Most homeowners in Gresham choose plastic risers with a green or tan lid that blends into the lawn. Concrete risers suit some tanks and settings better. The key choices are the diameter to match your tank opening, the height needed to reach grade, and whether you want an insulated or traffic-rated lid.

After risers are installed

Once risers are in, pumping and inspection visits in Gresham 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.

Signs your tank needs risers

If lids are buried, if the crew has to probe the yard to find the tank, or if past visits left holes in the lawn, risers will help. They also make sense if your system has a filter that should be checked often.

Choosing riser lids for a Gresham yard

Riser lids for Gresham homes come in green or brown plastic and in concrete. Plastic is lighter and easier to open, while concrete is heavier and harder to move. Either way, the lid should lock or screw down. Ask the installer to seal the joint so groundwater cannot leak into the tank.

Risers and lids for Gresham weather

Where soils are rated very limited, as most mapped soils near Gresham are, frequent checks of the tank and filter help protect the drain field. Risers make those checks quick. With about 58 inches of precipitation a year, a well-sealed riser matters. Poorly sealed joints can let groundwater into the tank.
