Why use Saddle Risers, Increments, and Cover Slabs with a Septic Tank

by Ri Industries Ri Industries No Comments

Septic tanks are one of those things we understand are important, but we’d rather not think about. We have them installed. We listen to the explanation of maintenance and we may even diary a time to have the tank pumped. Then we put all thoughts of septic tanks out of our minds and go about our business. That’s how it should be. Until the time comes for the tank to be pumped and we don’t remember exactly where it is. That can cause a problem. Luckily for you, Ri-Industries has a solution! Today, we’re going to tell you about saddle risers and increments.

So, what are saddle risers and increments?  The word ‘saddle’ makes it sound like we are going for a ride on the septic tank, but we assure you, our feet are staying firmly planted on the ground. Saddle risers are simply a way to help you avoid digging up your septic tank every three to four years for maintenance.

Think about it. The septic tank is buried deep underground. Although low maintenance is required, some maintenance will be required from time to time. How will the worker do what needs to be done? In the past, the pump-out contractor would have to dig down until he reached the septic tank. Now saddle risers, increments, and cover slabs work together to help the worker avoid all that painful digging and disruption to your outdoor area. No more guessing the exact spot where the septic tank is located. The saddle makes it easy to find, open and access septic tanks to pump out the contents and quickly re‐seal the cover. The covers are gas tight to contain odours and water tight to prevent effluent leaking from the septic tank or water from entering the septic tank.  They can also stop children and stock falling into or accessing your septic tank.
