Drainage

The drainage of rainwater is significantly important when starting a construction project, as without any efficient drainage we would be prone to increased flooding, which could ultimately cause problems for buildings and the land itself.

Howarth Timber & Building Supplies works closely with ACO to provide solutions for surface water control, and our plastic drainage systems are lightweight and easy to use while offering flexibility and strength.

Our rainwater plastic plumbing systems are designed to collect and move rainwater to either allow for harvesting (ideal for watering the garden) or direct it into the main drainage system. This is especially important to do around buildings to prevent damage caused by a build-up of water. 

If you are interested in purchasing any drainage pipes or products, or are just seeking further advice, please contact your local friendly Howarth branch.
