How Siphonic Roof Drainage Prevents Risk of Flood

In many parts of Asia, incessant and heavy rains during much of the year pose a risk of flooding, in turn putting lives and property at risk. To mitigate the damage posed by flooding, it is extremely important that buildings are equipped with the proper drainage systems that enable the seamless flow of rainwater from the buildings to the main sewerage systems. The traditional roof drainage system with gutters has now made way for the siphonic roof drainage system which is known for providing a much more efficient system for drainage from the rooftops, whatever the design plan may be.

In a siphonic drainage system, the key elements are the siphonic drain and the downpipes alongside a network of horizontal collector pipes. When the horizontal pipes in the system get filled to capacity, they create low pressure in the downpipes which causes the water from the horizontal pipes to rush into the downpipe and into the collector. Through this continuous action of pressure, the water is sucked out of the area. This ensures that there are no pools of water anywhere on the roof and this works even in the case of a flat roof design.   

As mentioned, the entire siphonic drainage system operates through suction action. The high efficiency design of the siphonic drainage system ensures that there is no air in the downpipes, thereby enabling higher suction capacity and better drainage with these systems.

The suction based operation of the siphonic roof drainage also makes it suitable for installation in low-rise buildings. Without having to construct or install a pitch, the siphonic drainage system collects the water from the roof through a series of horizontal collectors. The pipes for the collection can be installed completely in the horizontal direction without affecting the drainage.

In siphonic roof drainage systems, the pipe network is significantly less complicated and does not require too much area. There are far fewer downpipes for the drainage of the accumulated water which do not interfere with the architecture of the building either and are suited for installation even in harsh weather conditions.

Maintenance Tips for Siphonic Drainage Systems

For large and complex roof structures, ensuring proper water drainage can be a complex process. Gutters and downpipes are by themselves inadequate for flat-roofed high rise buildings and this poses a risk of allowing the rainwater to accumulate on the roof and eventually become either a breeding ground for microbes and slime, causing health and sanitation issues, or seep into the building, damaging its structural integrity. In such cases, installation of siphonic roof drainage systems is an ideal solution for water management. These systems are much more efficient when it comes to draining out the water from large and complex flat roof structures, as they drain the water out through a suction action. Post installation however, some maintenance of the system must be done in order to ensure that the system keeps working smoothly. Take a read at these maintenance tips for siphonic systems:

Some Facts About Siphonic Roof Drainage Systems

Image
For homes constructed in rain-intensive zones in Asia, and even in other areas which receive significant rainfall in the year, a key consideration is the installation of a roof drainage system which can collect the rainwater and storm water accumulated on the roof and drain it to a tank from which it can be used as required. The installation of a roof drainage system is important for several reasons, not the least of which is to prevent seepage and damage to the external structure of the house, which in the long term can also impact its life. Thankfully, now there are some excellent solutions to minimize the water damage to houses from rainwater accumulation and these are in the form of siphonic roof drainage systems. Let us take a brief look at the siphonic roof drainage systems:

Three Advantages of Installing Siphonic Drainage System for The Rooftop

Image
In areas where there is significant rainfall during part of the year, the installation of a roof drainage system is instrumental in enabling the flow of accumulated water from the roof and preventing structural damage. Conventionally, roof drainage systems are designed in a manner that there is a slope which takes the water to the lowest level, where a downpipe is positioned. However, traditional roof drainage systems have a fundamental problem in that they are dependent on gravity carry air along with water. It is here that siphonic roof drainage systems come into the picture, allowing for higher efficiency even in flat-roofed buildings. Let us look at the three top advantages of siphonic roof drainage systems:
