In 2009 the Rotherham suburb of Aston suffered significant property flooding both internally and externally. In response Rotherham MBC applied to DEFRA for a grant to install property level flood protection in the area affected. The grant application was successful and the Council appointed Phoenix Adam Ltd to undertake property level flood protection surveys for over 100 properties in Aston.

We provided the following services;
- Flooding expert representation at local public meetings,
- Detailed site level survey within each property boundary,
- Resident face to face interviews to obtain historical impact evidence,
- Site survey of all potential flood water entry points,
- Strategic overland flood route assessment,
- Mitigation measures specification for each property,
- Mitigation measures install survey for each property.
We used numerous data sources to establish a design flood level for each property, including eyewitness interview, previous strategic flood risk reports, previous 2D modelling studies.
We proposed various flood protection measures for each property, such as:
- Flood doors
- Flood barriers
- ‘Smart’ Air bricks
- Sealing of cable entry points
- Sealing of permeable brickwork
- Non-return valves on external and below ground plumbing
At certain locations we were able to propose more strategic options by land-forming to direct flood water away from property. Low cost, high impact solutions were implemented simply by re-profiling grass verges.
We produced a two stage report for each property. The first stage was a pre-install survey report assessing flood risk from all sources and potential flood water entry points for internal flooding protection. The second stage was a post-install report to confirm that the measures proposed had been installed properly and were working effectively to the resident’s satisfaction.
The initial project covering just 44 properties was delivered on time and within budget. We received positive feedback from Rotherham MBC who then extended the scope to include a further 57 properties in the same locality.
