Giải thích
Clear-water drainage such as foundation and sub-soil drains must be collected in its own sump and pumped to an approved disposal point, not mixed with sanitary sewage. This avoids overloading the sanitary system with ground water and keeps a clean-water pump from handling sewage. The clear-water sump does not need to be gastight like a sewage sump.
