Wessex Water has awarded an AMP8 framework contract for water quality monitoring for Urban Pollution Management (UPM) assessment - Storm Overflow Assessment Framework (SOAF) level 3-4.

When storm overflows spill, diluted storm sewage enters the environment, impacting the chemical and microbiological water quality of receiving and downstream water bodies. Effective UPM diminishes the environmental harm and ensures that water company discharges allow rivers and coasts to comply with Environment Quality Standards.
