Water supply system |
*Technology Cooling of the generator with the most amount, about 80% of all water *Fire control Fire control, flux larger than 15 Liter/s, can get to the highest possible fireLiving *Water supply way - Head within 20 m-80 m, water supply by gravity,from upstream(near dam,penstock in house, near turbine cover) - Head<20 m & head >80 m, pump,from downstream or underground |

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 |
