Summary documents
Customer summary

Catchment Strategic Plans (CSPs)
We've split our DWMP into 13 planning areas. Each CSP provides a breakdown of the plan for that specific area in our region. They cover the estimated impact of future risks and challenges in that area, plus the long-term plans we've collaboratively developed to tackle them.
The CSPs range from 30 to 50 pages. It should take about 45 minutes to read each one.
