BRAVA for the Stour catchment

The Baseline Risk and Vulnerability Assessment (BRAVA) is an important step in the development of our DWMP in order to understand current system performance and future vulnerabilities. Understanding the current and future risks means that we can identify the investment needed to manage and reduce the risks to Band 0 (not significant level of risk).

A BRAVA assessment has been completed for each of the wastewater systems in the Adur and Ouse catchment that were flagged during the Risk Based Catchment Screening (RBCS). A risk assessment is completed for all 14 planning objectives.

 

The output of the BRAVA shows
  • the current risks and issues in each wastewater system within the Stour catchment – providing a baseline from which we can assess future risks
  • the future risks in 2030, 2035, 2045 and 2050 (where the methodology currently allows us to assess the future risks) so we can understand how the current risks may change without additional investment
  • the key issues behind the future changes in risk including:
    • a deterioration in the condition of our wastewater systems
    • climate change – including the increasing frequency and severity of droughts and storms
    • growth and urban creep
    • a combination of any or all of these that are relevant in the catchment being assessed.

Notes

  1. In the BRAVA results table, “not flagged” means no risks were identified in the initial Risk Based Catchment Screening using the nationally set criteria. Wastewater systems not flagged were screed out and did not progress to the BRAVA stage. “Not applicable” means the Planning Objective was not relevant within the wastewater system. For example, where a system has no Storm Overflows, this will be marked as “Not applicable”.
