Septic Tank Riser Installations
New septic tanks have attached risers, but many older tanks do not.
Risers bring the access of the septic tank to ground level or just below grade. This alleviates the need to pay for labor costs every time the septic tank needs to have its regular maintenance pumping. Check out this blog post that explains even more.
We recommend installing them before extensive landscaping. This way, when the tank needs pumping, we only remove a few lids. Without risers, we might disrupt your grass, rocks, or stone pavers.
Septic tank risers are an extremely safe and have specialized square drive screws to discourage unauthorized entry. The lids are constructed with strong poly-HDPE and include top UV protection. This prevents warping or wear from the hot Arizona sun. Each riser lid includes a foam gasket for an airtight and watertight seal to our corrugated riser pipe.
Risers come in two sizes: 18″ and 24″. Homes built between the 1970s and mid-1990s typically used 18″ risers on one-compartment septic tanks. The new standard, 24″ risers, now fits both one- and two-compartment tanks. For two-compartment tanks, install risers on both the inlet and outlet sides to ensure proper pumping access.
Another important reason to install septic tank risers on a two compartment tank is that many of those tanks have an effluent filter in the outlet baffle assembly. The filter should be pulled 1-2 times a year and cleaned off to prevent any backups from occuring. The filter is an important part of the septic system as it keeps solids from entering your disposal field. Having risers present make this task simple and much more cost efficient than digging down to the tank lid for each cleaning service.
Traffic-Rated Septic Tank Risers
Traffic-rated septic tank risers withstand heavy weight and pressure from vehicular traffic thanks to their robust design. These risers attach securely to traffic-rated or reinforced septic tanks. Don’t install traffic-rated risers on regular concrete, poly, or fiberglass septic tanks.
In some cases, the septic tank may be located beneath a driveway, parking area, or other areas where vehicles regularly pass over. In these situations, use a traffic-rated septic tank riser. It supports vehicle weight and load without damage or collapse.
Traffic-rated septic tank risers use durable materials like reinforced concrete with steel rings and lids. They handle specific load-bearing capacities. Engineered to withstand vehicle traffic pressures and stresses.
