Septic Tank Emptying
Contrary to what many believe, there is no "rule of thumb" for how often septic tanks should be emptied. For example, an older system with an undersized tank that is being used by a large family will require much more frequent pumping than a new system used by only a few people.
The general advice from the Environment Agency is that septic tanks should be emptied or de-sludged once per year by an operator licenced for the carriage of waste by the Environment Agency.
A septic tank is considered to be full when 35 percent of the interior space is occupied by solid material, or sludge. The tank will always be full of water, which is what you will see if you open the tank. The solid materials gather at the bottom of the tank and settle there. Eventually, this sludge must be pumped out. If the tank is allowed to fill above 35 percent, there is a risk of solid waste entering the field lines to the drainage field or clogging of the inlet to the tank. Both of these situations can result in major problems and costly repairs.
Bates Environmental will be pleased to advise on the optimum emptying schedule for your particular installation. When you have it emptied, we will be able to tell you the condition of the tank and how full it was. Use this information to help you determine when to carry out the next pumping.
