A maintenance program should be established for the entire wastewater disposal system. Predicting <br /> septic tank pump-out intervals is impossible because it is unknown as to the number of on-site people <br /> at any given time,and the composition of influent throughout the year. <br /> The second maintenance issue will be the washing"off the BioTube f Iters:periodically, preferably at <br /> tank,pump-out. A waterline with a hose.bibb should be installed, or made available near the pump <br /> chamber tank for BioTube filter maintenance. <br /> Clean-outs will be installed at the distal ends of each lateral through what is referred to as."turn-ups" <br /> or"sweeps" as.noted. on the plan schematics. By using along"battle-brush" or small diameter <br /> "Snake7 arrangement,the interiors of the laterals can be cleaned of biological scum/slime build-up. <br /> This maintenance procedure should be done on an experimental basis, for example, initially on a <br /> monthly interval to observe if there is scum/slime build-up within the laterals. <br /> Water softeners should not be.installed because the sodium from water softeners will bind the clay <br /> fraction of the soil and impede permeability. Although this phenomenon-is debated in the scientific <br /> literature, it is a distinct possibility and should be avoided since it could lead"to a decrease in <br /> disposal area longevity.-. <br /> Accurate."as-bui"lts".of the domestic wastewater management system.installed must be supplied to <br /> { the Environmental Health Department. All applicable "distance" and"setback"requirements must <br /> be strictly followed: <br /> It is imperative to recognize that all septic systems arid disposal"areas have a lifespan. This lifespan <br /> is unpredictable due to the numerous operational and environmental factors-involved. A critical <br /> lifespan issue is"controlling the on-site water use as much as possible. This may"be accomplished by <br /> _using low flow toilets and spring-loaded'sink faucets. 'Restricting water use also includes checking <br /> -for water leaks in toilets, dripping faucets, etc. on a"regular monthly`basis.. <br /> 22 <br /> Chesney Consulting <br />
