Planning and evaluation of Zhumadian urban emergency water supply water source
Planning and evaluation of urban emergency water supply source is an important content of urban geological sur-vey.In the urban geological survey of Zhumadian,the urban emergency water supply source was planned and evaluated.Two groundwater emergency water supply sources are planned in the fourth water plant area and the third water plant area.Four wa-ter plant area,14 Wells are laid,with a daily mining capacity of 30 960 m3/d,mining 180 days,the maximum depth value is35.93 m;threewaterplant area,6 Wells,daily mining capacity of 8640 m3/d,180 days,the maximum depth value is 43.05 m.With the well loss,the maximum depth value is 40.99 m and 45.81 m respectively.The buried depth of the roof of the deep aquifer in the two areas is greater than 90 m and more than 79 m respectively,and the maximum dynamic water level of groundwater is 71m and 75.81 m respectively,which are less than the buried depth of the aquifer roof,so there will be no aquifer drainage or destructive mining.
