Surface Water Drainage
What is surface water drainage?
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.
Types of Surface Water Drainage
Manholes
Manhole covers are used to create an easier access to underground drainage systems, while also ensuring animals, humans and unwanted materials are kept out. It is essential that manhole covers are up to a high standard, mainly because of how they are placed in the middle of paved roads and areas. Due to the resilient material of Howarth’s manhole covers, they are strong enough to be able to hold a lot of weight, such as vehicular traffic.
Drain Channels
Drain channels are installed to support the removal of water from roads, driveways, and other paved areas, to prevent the risk of puddles from forming. ACO rain drain is a renowned supplier for drain channels, as their drain channels are designed to provide surface water drainage for a range of both domestic and light duty traffic applications. Reinforcement mesh is necessary in preventing excess water from draining away, as the mesh is used with steel. So, by adding the reinforcement, it will help to strengthen the overall structure.
If you are interested in purchasing any surface water drainage products, or are just seeking further advice, please contact your local friendly Howarth branch.
