The Study On The Planning Of Water Supply Of Shenzhen Yantian District

With the rapid development of China’s economy and urbanization continues toimprove，which has put forward a higher requirement for the construction of urbanwater supply system. Especially in some of our mountain city’s water supply systems，urban water supply，water pressure are facing new challenges.This thesis studied on Shenzhen Yantian district water supply planning，mainlyhave done the following works：analysis the present water supply system；long-termwater demand forecast；raw water system and water plant layout planning；watersupply network planning；utilizations of unconventional water resources. In the currentsituation analysis，the paper present some problems after the preliminary investigationand the data analysis. In water demand forecast，the study take Classified land areaindicator and Classified GFA indicator to forcast the water demand in2030，andchecked the result by a variety of methods. In terms of the raw water system planning，the paper determine the long-term raw water supply program after the supply&demand analysis，and plan the water plants layout. To ensure the layout to be morereasonable and reliable，the research also take computer software to calculate thegravity，cape pressure pipe network system，and checked under the fire，accidentconditions. The reserach based on the adjustment calculation result，and combined withthe terrain of each piece in the region to improve the water supply system. Besides，tomake full use of the local water resources，the article analyzed the local recyclingwater，rain water and other unconventional water resources.
