Exploring the Cost Benefit of Separating Direct Surface Water Inputs from the Combined Sewerage System
ISBN: 1 84057 533 6
Urbanisation and climate change are increasing the volume of rainfall discharging to the public combined sewerage system, resulting in increased risk of flooding and pollution with unnecessary pumping and treatment costs.
This project investigated the potential solutions for taking out surface water from existing combined sewerage systems, identifying the criteria that produce both positive and negative cost benefits to stakeholders, through initially a desk top exercise followed by the development of a simple spreadsheet 'Decision Support Tool' to assist the industry, and the application of pilot studies to confirm the outputs of the research.
