Septic Tank Risers
Installing Septic Tank Risers
A septic tank riser is an extension that helps lift the septic tank lid higher up to the surface. Installing risers makes it possible to access a septic tank with ease and no more digging will be necessary when repair or maintenance work has to be carried out. When a professional has to dig and look for the lid, it can be a very time consuming and ultimately very expensive too. Easy access to the tank means that homeowners can save a lot of money on maintenance.
Septic tank riser installation can be handled by a homeowner but a professional plumbing company will always be able to do a more finished job.

Different Riser Materials
Concrete septic risers, polyethylene and PVC are the three materials that risers are usually made of. Each of these materials differs in durability, price and ease of installation.
Concrete is the cheapest but it is also tends to be the most difficult to install as it is very heavy.
In comparison, polyethylene risers are easier to install as they are considerably lightweight. Soil erosion does not affect them too much but they tend to allow water and gas leakage.
PVC is a more expensive material. It is the lightest of the three which makes it the easiest to install and it also does not leak gases or water into the drain field.
Types Of Installation
Every time the septic tank has to be accessed, you have to dig down to the actual tank to access the lid. The risers are lid replacements and septic tank access is brought closer to the surface of the ground around it. This access could be above the ground where the risers are easily visible or may be concealed just below the surface. Above ground installation is largely used in areas that do not interfere with any lawn care or those that are hidden from sight and it allows for labor-free maintenance. Underground installation is just below the surface and only some grass has to be removed to access the tank.
Most septic tanks are installed up to 3 ft below the surface. However, the average depth is 18 in. Risers are available in 6’ and 12’ heights and are stacked above one another other until they stop just below the surface or reach the surface.
In order to decide how many risers you need, the distance from the tank to area where the new lid has to be positioned, will have to be measured. In order to achieve the required height, any number of risers can be installed. The risers are affixed to each other with screws and this makes them air and water tight. This is a specialized job and you should get a professional to come and handle it for you.
