Water drainage system |
*Seepage drainage Seepage water, living waste water, technology waste waterGravity flow, water-collecting well * Maintenance drainage Gravity flow first, then use drainage equipment Four types: *Water-collecting well: the draft tubes are connected with the pipe, the water can flow to the water-collecting well *Collection gallery: in the bottom of the station, no water-collecting well *District drainage: two units, one water-collecting well *Moving pump: water-collecting well for every unit, move the pump |
