Try Intimidating Several Problem of Water-saving with as Regards

试压系统整体整改后,试压效率比以前提高了近60%,没有出现因自来水停水而不能试压的情况。按以前用水量,回、储水损失10%计算,我们每年节约用水大约5 000 m3。综合测评,一年可以回收投资。

After the integral change of pressure test system,its efficiency increased by nearly 60%,and there is no condition that pressure test could not be done due to supply cut-off of tap-water.Calculating in former water amount and 10% of backwater and storage water loss,5 000 m2 water could be saved every year.Assessing synthesis,the investment could be recovered in one year.
