Maintain your attenuation tanks with COVAC’s specialised tank lining and repair service. Attenuation tanks have an important role in water management, controlling water flow to prevent flooding and erosion. They also temporarily store the excess rain water, directing it to the main drainage system in a controlled way. This means they need to be kept up to standard to ensure longer lifespan, prevent structural wear and bacteria growth.

COVAC specialises in tank lining, using a range of high-performance coating systems to protect your tank from wear and damage. Benefit from a service tailored to your needs, addressing specific issues with your attenuation tank and providing you with complete peace of mind.

What are the typical problems with attenuation tanks?

The common problems you might encounter include structural degradation, leaks or sediment build up. Structural damage and leaks often come from weathering or general wear and tear and can compromise the efficiency of your tank. It’s essential to inspect and maintain your tank regularly to improve its longevity and ensure optimal performance.

What is the difference between a soakaway and an attenuation tank?

A soakaway absorbs and disperses rainwater into the soil, while an attenuation tank temporarily holds excess rainwater, gradually releasing it to prevent flooding and manage water flow.

Do they need regular maintenance?

Yes, your attenuation tank requires regular maintenance to ensure it remains in good condition. Routine inspections are essential to identify and address potential issues as promptly as possible. This way you can maintain the effectiveness of your tank for longer.
