Septic Tank Risers for Hollis 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 Hollis 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.
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 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.
Riser safety
Septic tanks contain gases and deep liquid, so lids must stay secured. Use lids with screws or locks, replace cracked lids promptly and never leave an opening uncovered. Keep vehicles off riser lids unless they are rated for traffic.
Is a riser worth it
For most homes with buried lids, yes. The savings from not digging on every visit, plus easier inspections, often cover the cost over a few pumpings. Ask your septic company to compare the cost with what you pay for digging now.
Choosing a riser installer
Look for a company that seals risers properly to keep groundwater out and uses secure lids. Experience with tanks common around Hollis and nearby communities helps them match the right parts to your tank.
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.
After the risers go in
Make a note of where the lids are for future owners and service crews. Mowing around them is easy if they sit flush, and they make it simple to check the effluent filter or water level. Report any loose or damaged lid to your septic company.
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.

Among the mapped soils within about two miles of central Hollis, the USDA soil survey rates 87% as very limited for septic absorption fields, 13% as somewhat limited and 0% as not limited. The most common drainage class is well drained.
