What is a Critical Drainage Area in Cumbria?

Cumbria is a beautiful county located in the North West of England. Known for its picturesque landscapes, Cumbria is also prone to flooding due to its extensive river network and the fact that it experiences some of the heaviest rainfall in the UK. As a result, Flood risk is a significant concern for the residents and businesses in Cumbria.

Cumbria's drainage infrastructure is essential to mitigate flood risk. To ensure the efficiency and effectiveness of this infrastructure, Drainage Cumbria, a leading drainage company in Cumbria, undertakes Critical Drainage Area assessments that identify areas at the highest risk of flooding. These critical areas must receive specific attention by local authorities, businesses, and individuals to ensure that they are prepared should a flood occur.

In this landing page, we will cover what Critical Drainage Areas are, how they are assessed, and why they are vital for flood risk management.

What is Drainage?

Drainage is the process by which water is collected or removed from surfaces such as roads, buildings, or fields. Efficient drainage systems are vital for flood mitigation, as they help to control surface water runoff and reduce the likelihood and severity of flooding.

Drainage systems use a variety of methods to remove water. In urban areas, storm drains and sewers collect surface water and direct it into rivers or other bodies of water. In rural areas, ditches, culverts, and other open channels direct water into larger rivers or streams. Drainage infrastructure needs regular maintenance to ensure it remains effective, as blockages or damage can reduce the system's efficiency and increase the risk of flooding.

What is Flood Risk?

Flood risk is the likelihood and potential severity of flooding in a specific area. Flood risk is determined by various factors, such as land use, location, and drainage infrastructure. Areas prone to flooding are at risk of property damage, disruption of services, and potential loss of life.

To manage flood risk, local authorities develop flood risk management plans that identify areas at risk and assign measures to reduce the risk. These measures can include improved drainage infrastructure, flood warning systems, and evacuation plans.

What is a Critical Drainage Area?

A Critical Drainage Area is an area that has been identified as being at high risk of flooding due to ineffective drainage infrastructure, poor land management practices, or other factors. In a Critical Drainage Area, there is an increased likelihood and severity of flooding, which can cause significant damage and risk to life.

Local authorities have a responsibility to maintain drainage infrastructure in Critical Drainage Areas to ensure that the area can cope with the expected rainfall adequately. They can do this by improving drainage systems, increasing the capacity of watercourses, or developing flood defence systems.

How is a Critical Drainage Area Identified?

Critical Drainage Areas are identified through a process called Critical Drainage Area Assessment. Drainage Cumbria undertakes these assessments using a range of data sources, including topographical maps, rainfall data, and historical flood records.

During the assessment, Drainage Cumbria identifies areas that have a higher likelihood of flooding based on factors such as land use, slope, and rainfall. The areas that meet the criteria for a Critical Drainage Area are then prioritised for improvements to drainage infrastructure.

Why are Critical Drainage Areas Important?

Effective management of Critical Drainage Areas is essential for reducing the risk of flooding and associated damage. By identifying and prioritising areas at highest risk, resources can be effectively allocated to address the most significant problems.

Flood damage costs businesses, individuals, and communities significant amounts of money, and can have a long-lasting impact on the local economy. The impact on people's lives can be devastating, with homes and businesses destroyed and essential services interrupted.

In identifying and developing Critical Drainage Areas, Drainage Cumbria is supporting local authorities and other stakeholders in their efforts to reduce the impact of flooding in Cumbria.
