Currentness
Dosing tanks with one or more dosing siphons or pumps are required for leaching systems having 500 or more lineal feet of pipe. This will permit proper distribution of the septic tank effluent throughout the disposal area and give the absorption area a rest or recovery period between dosings. Dosing tanks for all leaching systems are a good management practice and reduction in leaching field size as described in SECTION 2.6.A. is permitted.
4.1. Dosing tanks. The dosing tanks must have a capacity sufficient to contain the required dose. The dose must be applied to the absorption field at a rate of 0.25 to 0.5 gallons per square feet per dose.
4.2. Siphon or pump capacity. The capacity of a dosing siphon should be determined from the recommendations of the manufacturer of this equipment.
If a pump is used it should have a capacity sufficient to empty the dosing tank in a period not to exceed 10 minutes. The pump controls must operate automatically and be sufficiently adjustable to deliver the required dose volume. High water alarms in dosing chambers are recommended but not required.
4.3. Pump for dosing applications. A sewage effluent pump may be substituted for a dosing siphon when gravity flow is not possible from the dosing tank or at the discretion of the Designated Representative. Only effluent quality pumps should be utilized in dosing application. Dewatering and grinder pumps will not be approved.
4.4. All distribution boxes utilized on dosed systems must be baffled in order to insure flow equalization.
4.5. Illustrations. Typical pump tanks, dosing tanks and details are illustrated in FIGURE 10, and FIGURE 11.
