Pollution Mitigation for Hobson's Brook and Coldham's Common

The purpose of this commission is to provide a specialist lead role for pollution mitigation evidence and design for Hobson's Brook and Coldham's Common. The commission must convert the available evidence into practical, defensible and measurable nature-based pollution mitigation designs capable of informing construction planning, consents, delivery sequencing and future performance validation.

The required outputs must support Cambridge City Council in moving from evidence and concept to delivery-ready technical design. The appointed supplier must provide a clear evidence trail from monitoring data and pollutant load analysis through to treatment train sizing, design assumptions, hydraulic performance, pollutant removal expectations, risks, uncertainties and monitoring validation requirements.
