Barratta Creek – Constructed Wetland

Detailed Design

Purpose

In order to reduce nitrates and sediment reaching the reef from farm land, AWC were engaged to transform an existing borrow pit into a treatment wetland.

Proposed Action

The borrow pit was reconfigured to include a sediment basin and extended flow path.The design slows irrigation runoff, settling sediments, then uses dense vegetation to remove nutrients. Once treated clean water is released downstream and/or re-used for irrigation.
