WCMS's are reports required for development within the Sydney Drinking Water Catchment. The WCMS must meet WaterNSW criteria for a Neutral or Beneficial Effect (NorBE) on water quality, as required under the State Environmental Planning Policy (Sydney Drinking Water Catchment) 2011. The reports need to be supplied with a development application, with the details to be included depending on the type and scale of development. Typically these assessments will address:

• Stormwater management
• On-site wastewater
• Erosion and Sediment Control / Soil and Water Management

The level of detail required depends on whether your development falls under Module 1, 2, 3 or 4. Once this has been established, can can prepare the report to meet the requirements. For example, a Conceptual Erosion and Sediment Control Plan is required for all new dwellings with construction area >250m², MUSIC stormwater quality modelling and a Soil and Water Management Plan are required for all types of development with more than 2500m² of impervious area.

These studies will be needed for sewered and un-sewered residential subdivisions (more than 4 lots), townhouse developments, extractive industries, car parks, commercial buildings and intensive agriculture and horticultural development where these impervious areas are exceeded.
