In sum if the seepage pit no longer drains into the surrounding soils, you need a new one.

Otherwise the old pit needs to be abandoned: pumped out and filled-in with soil and rock to be safe. Dig trench for drain pipe,5" Pro Series Channel Drain, Flo-Well, and EZ-Drain. Dry fit (no glue) the entire drainage system from the 5" Pro Series Channel Drain to the pop-up emitter. The Flo-Well and EZ-Drain should be installed at least 10 feet away from any existing structure.

In the worst cases, you may have to install a drainage system. Dirt piled up willy-nilly may well erode when it rains unless you pay attention to how you layer your berm, assuming that you want to avoid the cost of a berm composed totally of topsoil.

Micro-perforated plastic drainage pipes for the consolidation of soils within tunnel excavations. The plastic drainage tubes are inserted into a pre-drilled hole in order to drain water from the soil behind or adjacent to the tunnel excavation.

For use in gravity drainage and sewerage systems, underground drain pipe and fittings can be installed to depths of up to 10 metres. The underground drain range is manufactured from uPVC or unplasticised Polyvinyl Chloride for added strength and its ability to be resistant to moisture and is suitable for both domestic and commercial solutions. Minimum longitudinal grade of % on structure shall be provided for drainage purposes. Designer may provide drainage toward one end of structure or, when structure length is excessive, provide adequate deck grades to drain the structure to both ends. If the top of rail grades remain constant over the length of structure, the.
