Soil and Water Management Plans

What is soil and water management plan?

A Soil and Water Management Plan is a formal plan required by councils across NSW to control erosion and sedimentation on construction sites. It outlines site-specific methods to reduce soil erosion, manage stormwater runoff, and prevent sediment, chemicals, and pollutants from entering local waterways and stormwater drains.

The main objective of an SWMP is to:

  • Prevent water pollution from construction activities.

  • Control erosion and capture sediment before it leaves the site.

  • Protect downstream water quality and sensitive environments.

  • Ensure contaminated soils and unexpected hazardous materials are managed correctly.

SWMP vs. Erosion and Sediment Control Plans (ESCP)

The type of plan required depends on the size and complexity of your project:

  • Erosion and Sediment Control Plan (ESCP): For small projects with less than 2,500 m² of disturbance (e.g. single residential allotments).

  • Soil and Water Management Plan (SWMP): For larger projects with more than 2,500 m² of disturbance (e.g. subdivisions, civil works, commercial developments).

Many NSW councils require an SWMP at both the Development Application (DA) stage and the Construction Certificate (CC) stage.

Why Soil and Water Management Plan Are Important?

S and W Plan 3

The building and construction industry has a significant impact on the environment, particularly on waterways. Construction materials such as sand, cement slurry, paint, and soil can cause:

  • Fish and aquatic plant deaths.

  • Silting of streams and creeks.

  • Stormwater pipe blockages, leading to flooding.

Even small amounts of pollution from multiple construction sites can collectively cause major environmental damage. A  SWMP ensures your project is compliant with council requirements while protecting the environment.
