Rainwater & drilling: filtration and safety

Filtering rainwater or borehole water

An alternative water source (rain, well, borehole) requires an adapted approach: pre-filtration of sediments, refinement (taste/smell) and microbiological safety according to use.

Key steps

Pre-filtration

  • Retain sand, sludge, rust and suspended solids.
  • Protect subsequent stages and stabilize flow.

Securing

  • Appropriate treatment solutions ( Trio stations or UV plant, depending on configuration).
  • Sizing according to volume and autonomy constraints.

Advice

Before choosing, clarify your use (WC, washing, showering) and your expected level of autonomy.
