Wastewater Disposal System Operation <br /> The effluent will be pumped through the EnviroServer ES25 tank for nitrification/denitrification <br /> cycles. The effluent will then be pumped from the ES25 to six laterals to be equally distributed <br /> over a 3,600 ft' filter bed area. <br /> Page -9- <br /> Chesney Consulting <br />
