Rule 15-18-77-5.5.14 - Absorption Bed [Multi-pipe System]1. Multi-pipe systems installed in a bed configuration shall have the same lineal foot requirements as indicated for their respective trench configurations. The length and width of the bed to be constructed will be determined by the number of multi-pipe systems wide and the length selected to comply with the lineal footage required under Table IV.2. The multi-pipe system shall be placed side by side in the bed. Any side by side placement of multi-pipe systems shall constitute a bed.3. The bottom of the bed should have a relatively level grade, from the end and side to side. The grade within the bed shall not exceed the grade allowed for trench installations.4. The effluent must be equally distributed to the bed by means of a distribution box or with a pipe manifold.5. The multi-pipe system may be cut in-order to accommodate setbacks. The multi-pipe system shall be cut to a length which preserves the integrity of the banded void pipes and provides adequate banding of the system a minimum of every 18 inches to a maximum of every 20 inches. Manufactured couplers shall be used to join cut ends of the void pipes.6. The system shall be covered with a manufacturer-approved geotextile cloth before backfilling.7. The geotextile cloth shall cover the open ends of the void pipes.8. Care should be taken to prevent heavy machinery from damaging the bed during backfilling.15 Miss. Code. R. 18-77-5.5.14
