Subject: Leach bed, trench backfill Как назвать эти Leach bed,trench backfill ??The septic field consists of a grid of perforated pipe laterals laid into trenches, leaching pits or galleries arranged to allow equal distribution of the waste-water discharges from the septic tank. Distribution boxes are used to equalize the flow and distribution to the laterals and leach beds. The trench backfill material needs to be free-draining material that will allow lateral distribution of waste water, further facilitationg even and equal distribution. Мой вариант: Заранее спасибо. |
Leach bed -- фильтрующий пласт, горизонт, слой Trench backfill -- заполнитель, засыпка траншей (backfill - a trench was dug out and then filled back) pipe laterals -- горизонтальные трубы (отводы) septic tank -- септик lateral distribution -- площадное распределение |
