Wigan preliminary flood risk assessment (PFRA)
One of our statutory obligations, under the Flood Risk Regulations 2009, is to undertake a preliminary flood risk assessment (PFRA).
The purpose of the PFRA is to assess surface water flooding from information gathered through a data collection exercise on past and future flooding.
The assessment identifies any flood risk areas of national and local significance.
We completed our first preliminary flood risk assessment in 2011, with additional information published in 2017.
Section 19 flood investigations
As a Lead Local Flood Authority (LLFA), one of our duties under the Flood and Water Management Act 2010 is to investigate significant flood events and make our findings public.
In line with policy, we define a significant flood as one where either 5 or more residential buildings or 2 or more commercial properties were affected.

Greater Manchester Integrated Water Management Plan – Hindley
In September 2021, a Memorandum of Understanding was signed by the Greater Manchester Combined Authority, Environment Agency & United Utilities, creating the first Partnership looking to manage water differently across the city region.
The Greater Manchester Integrated Water Management Plan (GM IWMP) sets out the vision, ambitions and objectives which we aim to achieve by 2050. At the core of this initiative is the need to achieve continuous advancement through sustainable water management, enhancement of the natural environment and the development of resilient infrastructure to withstand flooding and the effects of climate change.
The IWMP team with Wigan Council have collaborated to support a place-based programme for the area of Hindley and Platt Bridge. This project team aims to develop and implement a comprehensive strategy addressing both flooding and water quality, through a multi-agency approach. By creating this strategy, true integrated water management can be deployed in the area, fostering a safer, healthier and more resilient and sustainable environment.
