9. The Micker Brook Delivering evidence-based pilot project
To address Diffuse Urban Pollution issues
Funded by United Utilities Catchment Wise
Innovative approach
Engaging the public locally
Targeting issues found during a river survey

11. River survey Phase 1: Desk-top study Phase 2: Primary ground survey
Phase 3: Wet weather sampling survey
Phase 4: Data analysis – report findings
Phase 5: Engagement

12. Prepare Desktop study Gather knowledge Prioritise Understand waterbody
Plan and prepare team
Arrange land access
Logistics / H&S 12

13. Primary Ground Survey Waterbody-wide scale Target identified reaches
Micker is Brook 21km 13

14. Identify points
For further investigation in wet weather conditions…

15. Wet weather sampling

16. Wet weather sampling Analysed for: Nitrogen Ammonia Lead Copper
Phosphate
Silicate
Mercury
Zinc
Nickel
Lead
Copper
Chromium
Cadmium
Aluminium
Arsenic
Chloride

17. Wet weather sampling
Also:
Temperature
Conductivity pH

18. Data collected
Sources
Types
Severity

19. Findings
Urban run-off

20. Findings
Farm waste
Urban farm

21. Findings Possible misconnection Flagged up with United Utilities
Engaged locally…
Raw sewage

22. Local Residents
Presented to a residents group near a suspected misconnection

23. In the Library Engaging the public in Cheadle Library on
misconnections
surface water flooding
Working with Stockport council on surface water flooding
Using a model to help demonstrate.

24. University of the 3rd Age
Engaging with U3A on surface water issues and misconnections.

25. Engaging the public

26. Next Steps In Micker Brook Follow up investigations
More public engagement opportunities
In Mersey Basin
Needs roll out to other urban waterbodies
Nationally
Training other catchment hosts in this technique

27. Future
Less of this
… and more of this
