What is the correct configuration of pipes in a removable pumping station?

In a removable pumping station, the configuration of the pipes plays a critical role in effectively managing water and sediments. The correct choice indicates that both pipes are perforated, allowing water to enter and exit freely while also helping to filter out sediments.

Wrapping both pipes in hardware cloth enhances their structural integrity and provides an additional layer of filtration, reducing the risk of clogging. The inner pipe being wrapped with geotextile further aids in preventing fine particles from passing through, which can lead to sediment buildup and potential malfunction of the pumping system.

This configuration maximizes the efficiency of the pumping station by ensuring that water can flow effectively while minimizing sediment intake. It balances the need for water ingress with measures to protect the system from sedimentation, ensuring that the pumping station operates smoothly over time.
