What are Risers and Lids?
A riser is basically a connection that runs from your buried septic tank to a surface area of your yard, granting access to its interior. The tank themselves are normally buried, several feet underground, which helps eliminate the very real possibility of odor leakage. However, there are some serious drawbacks, for example not having access to the tank for cleaning and maintenance. A septic riser enables a tank to be buried a few feet beneath the earth while simultaneously allowing easy access when it becomes necessary to pump out the tank or for cleaning or inspection. With no riser, you must dig out the septic tank’s top surface and then find the septic tank lid (the access point). It’s easier, in the long run, to have a riser installed with a lid. Risers for septic tanks are generally found in three kinds of materials:
Polyethylene Septic Tank Riser
The polyethylene septic tank riser is often seen as a better choice. A possible drawback, however, is not always having a good seal in the connection between the riser and the concrete septic tank. This is where most of the problems happen, especially if the septic tank overflows.
Concrete Septic Tank Riser
This is the least expensive option, however it’s the most difficult to install due to its enormous weight. The lid of a concrete septic tank is also made of the same and is difficult to remove, also as a result of it being awkward and heavy. Depending on one’s landscaping choices, the concrete riser may also be seen as unattractive and therefore undesirable. And, additionally, risers made out of concrete have a tendency to degrade and can sometimes cause leakage after some years. As a result of all this, many septic tank owners tend to avoid concrete.
PVC Septic Tank Riser
The PVC septic tank riser is the most popular option for several reasons. Being light in weight, it’s easy to install, and its edges create a tight seal between it and the septic tank. It is, however, the most expensive, but people often feel the benefits are worth the extra cost.
Choosing the Right Riser
Concrete lids can be covered with gravel or camouflaged with stepping stones. The lid needs to be accessible once a septic tank needs a pump-out, so don’t place anything monumental on top of a septic tank riser. You will likely hire a contractor to not only install and remove your septic tank riser. So keep in mind that digging time equals charged hours and therefore if budget is an issue, the less expensive lid maybe more financially wise. And consider the fact that a septic tank riser lets you easily know exactly where the septic tank and its lid are located.
