Recharge

Rainwater harvesting design and implementation.

Systems for areas facing groundwater depletion, supporting recharge and sustainable water management. Sized for the roof area and rainfall a site actually has, not a template.

Sized against your roof area and local rainfall, because the recharge volume claimed in a CGWA application has to be one the system can actually deliver.

Who approves it

Usually a CGWA condition

Recharge is rarely optional. Where CGWA grants an extraction NOC it generally expects the draw to be offset, which makes a harvesting and recharge system part of the approval rather than an environmental extra.

Designing it against real roof area and rainfall matters, because a system that cannot deliver the recharge claimed in the application becomes a compliance problem later.

What tends to come with it.

Recharge design depends on what the ground below can actually absorb.
