� . � } G=18 A cleanout pipe of at least six inches diameter shall extend to the ground surface and be provided with seals to prevent odor and to exclude insects and vermin. A cleaning access of at least 20 inches least dimension shall extend through the cover to a point within 12 inches, but no closer than six inches below finished grade. The cleaning access cover shall be covered with at least six inches of earth. Holding tanks must be monitored to minimize the chance of accidental sewage overflows. A mechanical or electrical alarm must be activated when the tank has reached 75 percent capacity. Pr+oblems wftih Holding Tanks • The cost of hauling the sewage can be excessive. Costs of pumping septic tanks are $50.00 to $120.00 for � approximately 1,000 gallons. Costs may differ sornewhat for holding tanks since they are usually readily accessible. A family of four is likely to generate at least 200 gallons of sewage per day. At a cost of$50 per 1,000 gallons, the annual cost to remove the sewage would be $3,650. Cost will vary with amount of sewage and hauling fees. Water conservation will reduce sewage flow and hauling costs. • The liquid level in the holding tank will need to be co�tinuously monitored in order to prevent an overflow. A water meter should be used to measure all flow except • ' to the outside sillcocks. Water ineter readings can be used to determine the amount of sewage pumped and hauled. • Weather conditions or road restrictions may prevent hauling when necessary and require that the plumbing systems not be used until the holding tank has been . pumped. • A continuous contract must be maintained to be sure that pumping service is available and that the sewage can be treated and disposed of. � Holding Tank with Dralnfleld: � � An Alfiemative This installation has successfully been used in a number of areas in Minnesota and teaches homeowners to conserve water. If the � volume of liquid wastes generated is less than the treatment , capacity of the soil absorption system, then no wastes will flow into the holding tank.
