Roofwater Drainage System

In most parts of Asia, there is heavy rainfall for part of the year. If there is no proper channel for drainage of the rainwater, it can accumulate in massive volumes and cause flooding. While level surfaces on the ground are most prone to flooding, another area prone to water accumulation is the rooftop, especially of buildings with high rise and flat roofs. Ensuring that the water on the roof drains out, no matter how intense the rainfall, requires the installation of the proper roof drainage system. Whether you will need to install a siphonic roof drainage system or a traditional one will be determined by certain factors, which must be kept in mind. Take a read to know more about these:

For homes constructed in rain-intensive zones, a key consideration is the installation of a roof drainage system which can collect the rainwater accumulated on the roof and drain it to keep the roof dry. Traditionally, different types of roof rainwater drainage systems have been employed to keep roofs dry and the building safe from water logging and seepage. These roof drainage systems are of different types and for houses, one can choose from gutters, scuppers, inner drains, and siphonic roof drainage systems. Let us take a look at the pros and cons of each system in brief:

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:

Water accumulated on top of the roof of a building can not only be extremely inconvenient but can also cause problems of seepage in the building, affecting its structural integrity. Traditional gravity-based drainage systems have reduced drainage capacity and cannot be installed on all kinds of buildings. They are particularly inefficient with large surface areas on roofs and on flat, low-rise buildings. Siphonic drainage, which sucks the water from the roof and ensures complete drainage, is more suited to such environments. More and more people around the world are now opting for siphonic systems nowadays, in domestic as well as commercial buildings. Here are some of the advantages of choosing a siphonic system which make it the ideal choice for roof drainage:

  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.        Durable materials of rainwater pipe connector fittings are also r

  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 is a health and sanitation hazard
