This week we were working on two convenience stores that had been repaired in the last three years. The company had trusted the previous company to repair the system properly. One system had a tank that was cracked and the other system had risers and lids that leaked.
It pays to inspect what you are paying for when you higher a contractor. This got by the County Health Inspector. This riser had cracks in riser itself and it was not properly attached to the tank. This can cause a huge problem because when the seasonal high ground water table is higher than the interface of where the riser meets the tank then excess water leaks into the tank and is pumped into the drainfield. In this instance it caused the premature failure of the drainfield. If someone is installing a drainfield that it should last a lot longer than 3 years. Diagosing these failures properly is what you pay a good contractor to do.
The installation of dual alternating septic pumps is a requirement on systems over 500 gpd on commercial septic systems and residential systems over 2000 square feet. It is not a bad idea to have a built in redundancy for systems. We can design a system for a redundant or lag pump in the event of a main pump failure. We can make it so that you will get an alarm; however, the system will continue to function with the lag pump.
Installing commercial filters can improve the efficiency of the filtering depending on which filter you purchase. SWS carries filters from Tuf-Tite, Orenco, and Bear Onsite. These filters have been proving over time to provide excellent effluent filtering capabilities. There is a lot of science on effluent filters. The two main factors that affect the filtering capabilities is the pore size of the effluent filter and the amount of surface area that the filter has. The larger to orrifice size on the filter the more sludge that can enter the drainfield. The amount of surface area that the filter has determines the cleaning interval. So, the better filters have smaller pore size and more surface area. If you have small pore size and small surface area then the filter clogs too quickly.
