Drainage & Rainwater Management

Efficient drainage is a key part of many construction projects to prevent flooding and waste build up, which would allow bacteria to thrive and increase the potential for the spread of disease. 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.
