Choosing the Pipes for Roof Rain Water Drainage

Surface drainage of roofs is an important consideration for the construction of any building, particularly those with flat roofs. In larger buildings, there is also the matter of efficiency to be taken into account, as all water accumulated must be efficiently drained out. There are two different systems widely used for roof rainwater drainage, which include the traditional gutters and the advanced siphonic based drainage systems. These systems show higher efficiency with minimal pipe networks, thereby saving precious space too. In the installation of roof drainage systems, the pipe networks are supplemented by the right connectors and fittings to secure the connections. The choice of these fittings must be made by taking into account the following qualities and properties:

1.    Material: When selecting pipes for roof rainwater drainage system, the right choice of material is of the utmost importance. Since the pipes will be exposed to incessant and heavy rains, it is important that they are resistant to corrosion and rusting from the water.

2.    Function: The choice of roof water drain pipe must also be done keeping in mind the exact function to be served. Pipes for gutter or gravity-based rainwater drainage systems will be different from those for a siphonic drainage system.

3.    Durability: The pipes to be installed in the roof drainage system or rainwater management system must be durable and withstand damage even under extreme stress conditions. Pipes which are made from durable materials like plastic are hence to be given priority.

4.    Ease of installation: Installation of the rainwater pipes must be easy and must not take too much time or labour. At the same time, the systems must be securely connected to ensure that there are no leakages in the system and there is durability in the entire network.

5.    Service life and maintenance: In the installation of pipes for roof rainwater drainage system, the service life and maintenance requirement of the pipes must also be taken into consideration. Pipes which can function optimally for longer durations are important. Also, rainwater drainage pipes must be easy to clear of debris and must be resistant to scaling to ensure better functionality.

Key Considerations For Choosing Rainwater Pipe Fittings

  Installation of rainwater drainage systems is crucial for the optimal drainage of accumulated rain on the rooftops as well as surface roads. For rooftops, the rainwater drainage system consists of a range of downpipes and fittings that drain the pipe from the top of the building to discharge it into a tank for reuse or into the main drainage system. Rainwater pipe fittings are of crucial importance in the rainwater management system as they connect the pipes to ensure seamless drainage of the excess water. Here are the key considerations to keep in mind when choosing rainwater pipe fittings: 1.        Choose the fittings for rainwater drainage according to the requirement. From securing pipes to filtering out the debris, fittings serve different purposes. Choose from elbows, tees, crosses, sand traps and filters according to the requirement of the pipe network to ensure seamless drainage of the rainwater. 2.        D...

Disadvantages Of Not Installing Proper Roofwater Drainage System

  With the scarcity of water being felt in many parts of the world, there has been felt an increasing need for sustainable water management practices. However, there continues to remain a shortfall in the measures undertaken to efficiently conserve water and put it to proper use. One of the inadequacies also arises in the form of lack of adequate infrastructure for water management. In flood-prone regions and areas which receive heavy rainfall, the installation of rainwater drainage systems for rooftops is of essence, in ensuring proper drainage and preventing of floods. Read on to know the various disadvantages of not installing the correct systems for rooftop rainwater drainage: 1.        In area where rainwater management systems are not installed, in case of excess rainfall, there accumulates surface runoff on the roof. This accumulated water, if not drained off using a roof rainwater drainage system can lead to flooding on the roof. This in turn...
