* 应该在旱季的后半段(地下水位最低时)挖井。
Where deepening the well further is not possible due to water/sand ingress, jetting in the bottom of the well can provide a means of faster recharge into the well from deeper in the aquifer, meaning the well dries up less quickly. In this case a larger diameter screen (can be wrapped with geotextile) is jetted into the well base with the end protruding above the bottom of the well, after which it is plugged using a small bag of gravel. 如果由于进水或进沙无法继续加深水井,在水井底部进行喷射可以使得水从更深的含水层中更加快速地流入水井,这意味着水井干涸的速度减缓。因此应该先利用一小袋砾石将大口径滤网(可由土木织物包裹)堵住,然后再喷射至水井基底(水井底部凸起的部分)。
如果水井在旱季仍持续干涸,应在水井的上游进行补给。
