在位于消防储水水位与生活调节水位交界处的生活水泵吸水管开一个DN10mm小孔，水位降低至小孔，则进气停生活供水泵。 3(给水方案的确定和管网的定线以及各种计算
3.1给水方案的确定
该城市地势西高东低，地势相差79米，故采用分区统一给水系统。为保证水质，将水厂选在县城南部清水河上游，该县城为单水源，城市消防给水和生活给水采用统一管道系统;由于水塔容积过大，经济代价高，故不设水塔;为保证供水安全性和可靠性，采用环状给水管网;由于工业企业用水对水质无特殊要求，故采用统一给水系统。
3.2管网定线
管网定线取决于城市平面布置，供水区地形，水源和调节水池位置，街区和大工业集中用水等。考虑城市近，远期发展，管网布置成环状网。依据现有的道路规划，尽可能减少穿过铁路和高级路面以及其他重要建筑物，允许有个别管段不符合上叙规则。干管均匀分配，故按长度流量法来计算沿线流量和节点流量。管网采取环状网布置形式，在平面图上具体确定管线，在地图上量出长度(按比例尺1:10000)，进行节点和环编号，详见附录:管网初分流量草图。
3.3计算集中流量、沿线流量、比流量
根据地势分布情况，以黄河大街为界，将该城区分为高低区，再根据高低区的面积分布情况，算出高低区的最大日最大时用水量:
高区:Qh1=0.46×409.8=188.5L/s
低区:Qh2=0.54×409.8=221.3L/s their own conditions to develop the correct road, the maximum to avoid investment risk, gain profit.(three) vigorously promote the brand.

合计 19.84 201.67 221.51 4、最高用水时管网手工平差计算
该市的配水管网布置成环状，高区布置了4个环，低区布置了8个环;
控制点为管网中供水的最不利点，通常认为在平差时，满足控制点的水压，则整个管网的水压可以满足。本方案高区初选控制点为4号节点，因为该点所处地势较高(地面标高512.00m)，且离水厂较远，其服务水头为28m;低区初选控制点为15号节点。
流量分配的目的是用以初步确定管网各管段的流量，据此确定管径，然后进行管网平差。
环状网流量分配的步骤如下:
(1) 按照管网的主要供水方向，初步拟定各管段的水流方向，并选
定整个管网的控制点。控制点是管网正常工作时和事故时必须
保证所需水压的点，一般选在给水区离二级泵站最远或地形较
高处。
(2) 为了可靠供水，从二泵站到控制点之间的几条干管尽可能均匀
qq+=0,分配流量，并且满足节点流量的平衡条件，即。 iij(3) 和干管垂直的连接管，平时流量一般不大只有在干管损坏时才
转输较大的流量，因此连接管中可分配较少的流量。 4.1最高时管网初分流量

管网平差结果的校核:
管网平差的目的在于求出水源节点的供水量、各管段中的流量和管径以及全部节点的水压。管网的管径和水泵扬程，按设计年限内最高日最高时的用水量和水压要求决定。但是用水量也是经常变化的，为了核算所定的管径和水泵能否满足不同工况的要求，就必须进行其他用水条件下的核算，以确保供水安全性和稳定性。由于本工程不设置水塔，因此只进行消防时管网核算和最不利管段发生事故时管网核算。采用水头法进行校核。
在定线时高区假设了节点4为控制点，该点的地面标高为512.00m,需满足的最小服务水头为28m,则该节点的总水头为540.00m,然后进行水力计算，由平差算出来的各管段的水头损失(见表1-13 最高时平差结果)，推算出其他各个节点的水压标高，再算出每个节点的自由水头，比较每个节点的自由水头与要求的最小服务水头(不小于28m),比较自由水头是否满足最小服务水头。若是，则说明该点为控制点。
低区高区假设了节点15为控制点，该点的地面标高为476.00m,需满足的最小服务水头为28m,则该节点的总水头为504.00m,然后进行水力计算，由平差算出来的各管段的水头损失(见表1—14 最高时平差结果)，推算出其他各个节点的水压标高，再算出每个节点的自由水头，比较每个节点的自由水头与要求的最小服务水头(不小于28m),比较自由水头是否满足最小服务水头。若是，则说明该点为控制点。

据此，得到最高时水力计算表。从计算结果可知，除控制点外的其他节点的自由水头都大于28m, 确认节点4、15为控制点，各点水压满足要求水压。
5.2最高时二级水泵设计扬程
高区:
