The heavy rain recently has caused many failing drain fields in Carrollwood to back up. This particular system has failed because of a faulty joint on the inlet side of the dosing tank. The dosing tank is what is used to pump the effluent from the primary tank into the drain field. Some drain fields are elevated because they are in a high water table. Many of the failing drain fields in Carrollwood are because the have been installed in the water table or the water table has changed. The water table will change over time as development and construction occurs. A drain field that was installed 30 years ago could have been installed at a proper elevation only to find that building nearby has changed the water table. Many fields were installed too low to begin with in Carrollwood and the surrounding areas like Lutz and Odessa. We find most of our failing drain fields in Carrollwood are the result of being installed too close to the water table.
In this particular project the field has become hydraulically overloaded from the leak on the inlet to the dosing tank. When ground water constantly pours into a tank it never allows the septic field to dry out. Tampa Plumber is hoping that by repairing the inlet to the tank and pumping the tank a few times, coupled with an aggressive chemical treatment, we can get the system working again.
