Septic Tank Risers for Anacortes 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 Skagit County can add risers to most existing tanks.
How risers and lids work
The riser bonds or bolts to the tank opening and is sealed to keep groundwater and soil out. It is cut to reach just at or above grade. The lid sits on top so the tank can be opened by hand without a shovel. Some lids are insulated for cold weather.
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.
What affects riser cost
Price depends on the number of openings, how deep the tank is, the riser material and whether the job is combined with pumping. Deeper tanks need taller risers and more digging. Insulated or traffic-rated lids cost more.
What to ask about riser installation
Ask how many openings your tank has and which ones should get risers, what material they install, how the risers are sealed to the tank, and how the lids are secured. Ask whether combining the job with pumping lowers the total cost.
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.
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 Anacortes 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.
Making tanks easier to reach near Anacortes
If your service company has to dig to reach the tank every time, risers are worth asking about. Septic companies around Anacortes install them on most tank types, and the savings on future visits often cover the cost over time.
