Overview

What This Project Is All About

We’re rehabilitating the Currie's Sewage Treatment Wetlands to improve environmental outcomes and support a healthier local ecosystem. This staged project will clean, rejuvenate and replant the wetland ponds to restore their natural treatment function and support the Currie community and environment long-term.

What You Need to Know

Work Location: Currie Sewage Treatment Plant (STP)
Purpose: Restore wetland lagoons to improve water quality and environmental outcomes
When: Starting September 2025, delivered in three stages
What to Expect:

  • More vehicle and people activity near the site
  • Some noise and dust during works
  • No changes to your water or sewer services
  • Increased odour at times
Benefits: Cleaner water, healthier wetlands, and long-term environmental protection for Currie
disruption; no changes to your water or sewer services.

Why it matters

Why Wetland Rehabilitation Matters

Wetlands play a vital role in keeping our water clean. At Currie, the wetlands help treat wastewater by slowing it down and allowing plants and soil to naturally remove nutrients.

But over time, if wetlands are affected by increased flow, sludge build-up, and overgrown vegetation. When wetlands are overwhelmed, they can’t do their job properly — putting the local environment at risk.

By cleaning, restoring, and replanting the ponds, we’re helping the wetlands bounce back to full health, so they can support our environment and community for years to come.

Facts

Did You Know?

They help clean water by trapping sediment and absorbing nutrients like nitrogen and phosphorus before water returns to the environment.

Even small wetlands can support hundreds of species of birds, frogs, insects, and plants — many of them native or endangered.

They absorb water like sponges during heavy rain and storms, reducing the impact on nearby communities.

Healthy wetlands capture and store carbon dioxide, helping reduce greenhouse gases in the atmosphere.

The island’s wetlands are shaped by both freshwater flows and salty coastal influences, making them unique ecosystems that support a mix of salt-tolerant and freshwater species.
