Section 25-11 - Effluent Distribution Devices

Distribution boxes and flow divider tees are suitable for level or nearly level ground and are installed before the soil absorption system with the goal of splitting flows equally between soil absorption system laterals. Drop boxes are suitable for sloping ground and are installed to achieve serial loading.

(a) Distribution Boxes

• (i) The distribution box shall be installed on a level, stable base to prevent tilting or settling, and to minimize movement from frost heave.

• (ii) Boxes shall be watertight and constructed of concrete or other durable material.

• (iii) Boxes shall be designed to accommodate the inlet pipe and the necessary distribution lines. The inlet piping to the distribution box shall be at least one (1) inch above the outlet pipes and all pipes shall have a watertight connection to the distribution box.

• (iv) The box shall be protected against freezing and made accessible for observation and maintenance.

• (v) Boxes shall have flow equalizers installed on each outflow.

(b) Flow divider tees may be used in place of distribution boxes.

(c) Drop boxes are suitable for sloping ground and are installed to achieve serial loading. The drop boxes shall meet the requirements in paragraphs (a)(i through v) of this section.
