The Challenge

WRM has inspected and provided professional advice on stormwater drainage and flooding at over 6,000 residential, commercial and agricultural properties in the last 15 years at locations across the country to assist insurance companies with water damage claims.

These assessments investigated the causes and severity of the particular flood events and determined the contribution of local stormwater and riverine flooding to overall inundation at individual sites.

Key challenges include:

  • Being able to mobilise and provide adequate staff resources to inspect large numbers of flood affected properties on short notice;
  • Deliver reports quickly for the insurance companies to respond to claims promptly; and
  • Ensure assessments are accurate and able to withstand peer review and court scrutiny.
