Septic Tank Lid Information

What is a septic tank lid and why do I need one?  A septic tank lid allow you to easily locate the tank and provide access to the tank for inspection and maintenance. Your don't need to search for the tank (which can be quite difficult and time consuming) or pay a contractor to find it. A septic tank lid also prevents you from having to dig up the lawn each time you need to access the septic tank. Some localities also require septic system lids on new and/or older septic systems.  A septic tank lid attaches to the top of the tank over the outlet and inlet openings of the tank (or the pump-out opening) and they extend to ground level. It can also be installed to allow access to other system components such as distribution boxes.  Different types of septic tank lid: There are three different types of lids, concrete, PVC and high-density polyethylene. Concrete risers are quite heavy, making them difficult to install. Their lids are also heavy, making it hard to lift and access the septic tank. Backhoes are normally needed to install concrete risers. Some people find the lids unsightly and difficult to mow around. Concrete lids are also not completely waterproof, and problems can occur if surface or ground water leaks into the tank. PVC lids are easy to install and have light fiberglass lids that allow for easy access to the tank. PVC lids also have gaskets and are waterproof, and fasten easily to tanks. Polyethylene lids are difficult to connect securely to the tank, because most adhesives do not bond to polyethylene. These lids are also not as strong as fiberglass, requiring them to be domed to add strength. This causes the lids to stick above grade.  How much does a septic tank lid cost?  The cost depends on the type used, diameter and height. Estimated costs are: Concrete: $50-100 PVC: $150-225 Polyethylene: $100-200
