  4. The CSO Problem • Unpowered CSOs do not work consistently • Screens can block and often by-passed • Results in discharge of unsightly sewer litter • Sewer litter leads to customer impacts 4 wrcplc.co.uk independent | trusted | innovative

  5. Customer Impacts • Sewer litter leads to complaints, fines and very poor PR • Impacts on pollution regulators scoring indicators • Increased unwanted customer contacts • Reputational damage to the water industry 5 wrcplc.co.uk independent | trusted | innovative

  6. WRc CSO Design Principle Allow the natural Minimal Retain sewer litter hydraulic presentation of within the flow processes to occur litter to the screen 6 wrcplc.co.uk independent | trusted | innovative

  7. The 21 st Century CSO Solution • Design a CSO that retains sewer litter within the network • Provide a CSO solution that requires no power • Significantly reduces visible/aesthetic pollution • Reduce the frequency of screen cleaning • Provide a modular solution with a retro-fit capability 7 wrcplc.co.uk independent | trusted | innovative

  8. WRc CSO Design WRc Innovative 2 chamber design Solution Chamber Separates the floating debris and 1. returns it to downstream sewer Chamber Allows ‘clean’ water to spill to the 2. watercourse via the screened weir 8 wrcplc.co.uk independent | trusted | innovative

  9. WRcSO Chamber arrangement 9 wrcplc.co.uk independent | trusted | innovative

  12. The WRc CSO Advantages • Reduces debris presented to the screens by 98% • Reduces aesthetic pollution of watercourses and beaches to a minimum • Passive unpowered system that can be retrofitted • No E&M maintenance costs • Reduced SIM contacts and cost of spill clean up 12 wrcplc.co.uk independent | trusted | innovative
