The Importance of Septic Tank Risers

by Karl Holt

Installing septic tank risers are a highly recommended addition to your septic system. The septic tank riser will make maintaining and monitoring your septic system much easier and more convenient.

Septic Tank Risers will Lower Your Septic System Cost

Most states in the US require that approved septic tank risers be installed on any new system or upgraded septic system. Unlike many governmental mandates, this requirement actually has benefits. Your septic system is one of the most expensive mechanical features of your property. It is also one of the least monitored and least understood systems that you own. Without septic tank risers your system is “out of sight and out of mind.” Unfortunately, this mentality can cost you a lot of money down the road. The average septic system cost in the US is about $15,000. The average septic system life expectancy in the US is 15 – 20 years. If you add on the interest cost to the $15,000 and divide the amount by how long the system will last, your septic system is costing you more than $1,000 a year to own. Because of the cost associated with septic system ownership we strongly recommend that you learn as much as you can about it and monitor its performance regularly. The best way to monitor your septic system is by adding septic tank risers.

Advantages of Septic Tank Risers

Concrete Septic Tank Riser

The first benefit of a septic tank riser is the visual aspect. You’ll be reminded that you have a septic tank  every time you see the riser cover. This will keep this fact regularly on your mind. Many people don’t like the thought of the septic tank risers being visible in their yard because the old style concrete covers are not aesthetically pleasing. Modern septic tank risers and covers are much more attractive and blend with the surroundings. These modern septic tank risers are much easier to install. The old style concrete septic tank riser rings weigh hundreds of pounds. The concrete covers also weigh 60 – 80 lbs. Because of the weight, many people are discouraged from removing the cover and doing an inspection. Modern plastic septic tank riser rings typically weigh less than 30 pounds. The septic tank riser covers weigh less than 10 pounds making installation and servicing much easier.

Modern Septic Tank Riser

Another advantage of modern septic tank riser is that they are much easier to seal surface water from entering the tank. Old fashion concrete riser rings do not incorporate any gasket. Therefore surface water can easily flow between the joint between the tank and the riser ring and the cover and riser ring. Modern septic tank risers have a waterproof seal between the septic tank and the base flange. They also have a durable closed cell foam gasket to seal the joint between the riser ring and the cover. Modern septic tank riser covers are secured with threaded fasteners to prevent small children from curiously tampering with the cover and avoid the risk of falling into the septic tank.

How to Inspect Your Septic Tank

So now that you are reminded that you own a septic tank when you see septic tank risers you can perform some simple checks on the system. We recommend that the septic tank be inspected visually about every 6 months. To perform the inspection, simply remove the septic tank riser cover. With the cover removed, observe the water level height in the tank. A typical water level height is about 6” to 8” below the inside of the tank cover. This means there should be 6” – 8” of air space above the water. Depending on the location of the clean-out cover location on your tank you may be able to see the inlet or outlet baffle of the septic tank. If you can observe the inlet baffle (nearest to the house) the normal water level should be 3” – 4” below the bottom of the horizontal pipe. If you can observe the outlet baffle (nearest to the drainfield) the normal water level should be even with the bottom of the pipe or at most ¼” deep in the pipe. If the tank levels are elevated, this is an indicator that the drainfield is not functioning properly.

Other Benefits of Septic Tank Risers

Another benefit of adding septic tank risers is that adding an Aero-Stream remediation system will be very easy. Simply remove the septic tank riser cover, lower the diffuser assembly and bio-brush into the tank, drill a 5/8” hole through the plastic septic tank riser about 2-3” below the surface. Push the air line through the drilled hole and connect to the Aero-Stream aerobic generator unit. Done.

Easy, Fast & Efficient!

    You’re absolutely right. The septic system is really one of the least monitored and least understood systems in the house. I mean how many of us even given it a thought. We only think about it when something goes wrong. By then of course, it is a mighty mess. A regular check up can help you avoid a whole lot of heartache. There are plumbing companies that will do regular maintenance for a nominal fee and that really is the best solution. In this case, believe me prevention is definitely better than having to deal with the aftermath of septic tank problems. I know because I was one of those who learned it the hard way.
