Dam Breach Risk Assessment
October 23, 2020
Acquiring planning permission can be tough, especially when dealing with the Lead Local Flood Authority (LLFA). In a recent project we were approached by an agricultural client to assist in gaining the necessary planning permission for winter storage reservoirs, to capture rainwater for summer irrigation.
The LLFA raised concerns regarding the potential impact downstream, in the unlikely event of a breach of the reservoirs. Our surface water team developed a 2D hydraulic model to analyse and provide a detailed understanding of flow pathways and potential flood extents. The complex numerical analysis was presented in a simple way that all stakeholders could understand.
The team’s innovative techniques to work within a short timescale, in combination with providing a strong evidence base allowed the development to successfully progress through the planning process. Find out exactly how we did it below.
Our specialists have the technical expertise, experience, and the tenacity to assist with a wide range of developments. If you require more information, advice or help relating to flood risk, get in touch with our technical lead,

Since December 2024, the Environment Agency (EA) have released a series of flood and coastal erosion risk assessment updates, offering a clearer, more comprehensive picture of both current and future flood risk across England. What makes these updates so important? With approximately 6.3 million properties in England at risk of flooding and 3,500 properties at risk of coastal erosion by 2055, these updates are absolutely critical in order for you to protect and enhance your developments against the threat of climate change and extreme weather events. Whether a commercial or residential development, Envireau Water specialise in flood risk management and sustainable drainage solutions across the UK. By leveraging our technical expertise and deep knowledge of the UK regulatory system, we are known for achieving a positive outcome for even the most complex of challenges. Keep reading to find out what these updates mean for you.

Climate change is an urgent issue we cannot ignore, and requires the collective action of communities across the globe if the worst effects are to be mitigated. From rising sea levels, extreme weather events to a loss of biodiversity, the potential impacts are widespread. However, this world water day, the focus is rightly on glacial preservation - our planet's largest natural freshwater reservoir. Why is it important? At Envireau Water, we recognise the widespread impact that glacial meltwater has across the whole planet, leading to the escalation of more extreme weather events as a result. Not only does this impact the environment with the disruption of ecosystems and water cycles, but also has a profound impact on society and industries reliant on a stable water supply. As a team of water scientists, we have witnessed first-hand the undeniable impact that flooding and drought events have had on the mineral, agricultural, industrial and development sectors, from failing crops and flooded farmland to a halt in distilling operations and delayed development projects, the ripple effects of these events are felt across communities and businesses alike.

It is safe to say that Envireau Water have had a long line of success stories over our years of operation across our four sectors of expertise, with permitting and licensing being just one of our many service offerings. So, what has fuelled our success? To get some insight, we turned to our Specialist Water Resources team for their perspective. Penny , can you expand on Envireau Water's success in this area? 'Water is a vital resource across many industries, without which they would not be able to operate effectively. However, this does not come without certain regulatory constraints, which must be abided by. That's where we come in.

Achieving nutrient neutrality is a challenging task, and is one that developers all over the country have battled to achieve over the last 5-6 years. In March 2022, Natural England issued a directive to Local Planning Authorities, County Councils, the Environment Agency, the Planning Inspectorate, Natural Resources Wales, and DLUHC stating that, in specific river catchments, developments should not be permitted if the LPA cannot definitively ensure that it will not adversely impact protected environmental sites due to increased levels of nitrate and/or phosphate. While the current approach is efficient, robust, and objective, it can also be slow, costly, and overly complex—leading to potential project delays and increased expenses for housing developers. To address these challenges, the government released the Planning Reform Working Paper in December 2024. This initiative aims to unlock approximately 28,000 homes across seven areas in England that had been stalled due to nutrient neutrality concerns, backed by £47 million from the Local Nutrient Mitigation Fund.
