A multi-tank septic system is one of the latest, and possibly greatest, things in the world of septic system advancements. Every time you flush, you are filling one tank and/or moving and separating wastes into a couple of other tanks. In so doing, you have more room and more time between septic pumpings. However, the septic services and septic tank pumping for a multi-tank system is very different than that of a single tank system. Here is a little more on what you can expect from your next septic tank pumping when you have a multi-tank system.
A Longer, More Aggressive Pumping for the Solid/Semi-Solid Waste Tank
Since a multi-tank system separates the solids and semi-solids from liquid wastes, your solid waste tank may require a more aggressive pumping. Some liquid in this tank remains to help break down the solid wastes into semi-solids, but because the tank is often void of most liquid waste, it takes a lot of suction to clear this tank. You can expect service for this tank to take a little bit longer than usual when it is very full.
A Very Quick Pumping of the Liquid Tank, and Possibly a Second Pump Truck
Since your multi-tank system has already done most of the work of separating waste by type, pumping out the liquid waste should go very quickly. Additionally, your septic tank specialist may decide to use more than one pump truck and mobile tank to finish the job. This may not only shorten the time it takes to pump out the liquid waste tank in your system, but also shorten the time overall because there are two trucks doing the work of one.
A Thorough Flush and Pump of the System
A multi-tank system has three tanks; one to collect all the waste as it exits your home, one to collect and hold the solid/semi-solid waste, and a final one to collect and hold liquid waste. To really clear and clean the system out, your septic tank specialist (such as one from Martin Septic Service Inc) may thoroughly flush all of the tanks with water and re-pump. New treatments to help break down any more waste that you flush into the system may be added before the tanks are resettled. (Resettling the tanks means that each tank is checked to make sure there is a some water in the bottom of each to help them function as they normally would in between pumpings.)
