(一)

某城市拟对全市的给水系统进行全面改造,通过招标投标,选择了一家企业作为施工总承包单位。

在给水厂站施工过程中,对降水井的布置提出以下要求。

(1) 面状基坑采用单排降水井,布置在基坑外缘一侧。

(2) 降水井的布置在地下水补给方向适当减少,排泄方向适当加密。

(3) 当面状基坑很小时可考虑布置单个降水井。

(4) 在基坑运土通道出口两侧不应设置降水井。

为了保证滤池过滤效果,施工项目部对滤池施工过程中的每个环节都进行了严格控制。

施工期内,由于基坑内地下水位急剧上升,使基坑内的构筑物浮起,为此,提出了抗浮措施。

该给水工程在合同约定的工期内实现了送水并网。

[问题]

送水并网应具备哪些条件?
