Storm water and drainage systems protect against water damage

Superior rain water and underground drainage systems prevent structural moisture, mould, and frost damage. Effective systems can also prevent flooding in basements, pooling in yards, and slippery sheets of ice in passage ways. A building's drainage pipes include rain water pipes, drainage chambers, and basic water chambers for collection and storage.

Uponor has a complete range of storm water and underground drainage pipes, components, and chambers for all types of building foundations and properties. Superior drainage and storm water pipes are both easy to use and durable—their smooth interior surface prevents the accumulation of deposits. The double-layered pipes are rigid and easily installed at the desired angle.

Compatible components and chambers ensure that the system works well and is reliable.

House drainage system

Drainage and rain water pipes run alongside each other in the same trench. The water flows into the basic water drains from which they lead to the municipal storm water chambers. Underground drainage chambers are located in the corner of each building. These serve as the inspection and maintenance drains of the underground drainage pipes. Generally, rain water is also lead to the same basic water chambers, in which case the drainage pipe connections have ball valves to prevent water from flowing back into the drainage pipes during a flood.

Uponor underground drainage systems include everything needed for the construction of a functional and safe system:

  • Underground drainage pipe 110 SN 8
  • Underground drainage chamber 315 and raise component
  • Flexible connections
  • Yard chamber package

Storm water system

When left uncontrolled, rain and melt water can cause pooling and slippery sheets of ice. Over time, this can result in moisture damage to structures.

Rain water, otherwise known as storm water, must not be allowed to flow into underground chambers. This is because heavy rain will fill the chamber, which will in turn begin to push water into the building foundations, causing the pipes to work in exactly the opposite way they should. This will also happen if discharge pipes become blocked, such as by freezing up. Storm water systems are built to discharge rain water safely and to the correct place.

The Uponor storm water system includes the following components:

  • Storm water pipe 110 SN 8
  • Sealing rings
  • Drainage chambers
  • Flexible connections
  • Yard chamber package

Smart storm water handling

The significance of storm water management is growing in urban areas, where storm water drainage on a property often needs to be slowed down before it enters the municipal storm water chambers. The Uponor selection for small buildings includes storm water retention and collection tanks as well as storm water tunnels. The systems slow down the discharge of storm water or absorb storm water into the ground. Storm water collection tanks can be used to store rain water when there is a need to use rain water later, such as in watering gardens.

Storm water tunnels suitable for absorption serve as temporary reservoirs from which the water is absorbed steadily into the ground. A system consisting of tunnel modules and end plates can be installed in one or more lines without length restrictions. One tunnel has a volume of 300 litres.

Storm water retention tanks have a retention volume of 2,500 litres and lead to the municipal chambers. The Uponor retention tank is a simple, reliable solution from a domestic manufacturer. It is low in height and can be installed below ground.

A storm water collection tank safely collects rain water running off the roof into a tank for later use. The tank is made of polyethylene, which is a durable and lightweight material. An overflow pipe ensures that the tank water never rises above a specified level. Excess water is led into the storm water chamber, the absorption area, or a ditch.
