Why We Need Innovative Siphonic Drainage System?

Roof water drainage systems play a crucial role in protecting our homes and buildings from water damage caused by heavy rains and storms. Traditional roof water drain pipes have served us well for many years, but there's an innovative solution that's changing the game, i.e. the siphonic drainage system.

In this blog, we'll explore the benefits of siphonic roof drains and why they are becoming the go-to choice for efficient rainwater management.

Understanding Roof Water Drainage Systems

Such drainage systems are designed to divert rainwater away from roofs, preventing water buildup that can lead to leaks, structural damage, and even flooding. Traditional systems rely on gravity to move water through pipes and downspouts. While effective, they can be bulky and require extensive maintenance.

The Siphonic Drainage System Difference

Siphonic drainage systems, on the other hand, operate on a different principle. They use the power of vacuum and air pressure to rapidly remove water from the roof, offering several advantages:

High Flow Rates: Siphonic roof drains can handle significantly more water than traditional systems. They create a powerful vacuum that draws water into the drain pipes, allowing for faster drainage even during heavy downpours.

Reduced Pipe Size: Due to their efficiency, siphonic drainage systems can use smaller pipes, which are less apparent and cost-effective.

Less Maintenance: Traditional roof drain systems are prone to clogging and debris buildup. Siphonic drains are less susceptible to these issues because they evacuate water with force.

Design Flexibility: Siphonic drainage systems offer greater flexibility in roof design. They can accommodate longer horizontal runs and more complex layouts, making them ideal for modern architectural designs.

Energy Efficiency: The reduced pipe size and rapid water removal of siphonic systems can lead to energy savings by minimizing the need for oversized pipes and pumps.

Installation and Maintenance

Installing a siphonic roof drain system requires expertise, but once in place, they are relatively low maintenance. Regular inspections to ensure the system is functioning optimally are recommended. Cleaning debris from roof areas and gutters can help prevent clogs and maintain efficient drainage.

To summarize

Siphonic roof drainage systems represent a significant leap forward in rainwater management. As our climate continues to change, efficient roof water drainage systems like siphonic roof drains will play a vital role in protecting our homes and structures from water damage, ensuring a safer and more sustainable future.

Different Types of Rooftop Stormwater Management Systems

In rain intensive zones, a key consideration is the installation of a roof drainage system which can collect the rainwater and storm water accumulated on the roof of a building and drain it away from the house. Now there are some excellent solutions to prevent rainwater accumulation and these are in the form of roof drainage systems which also act as systems for rain and stormwater management. These roof drainage systems are of different types, which are as follows:

1. Gutters - The traditional roof drainage system in most old homes is a network of gutters which are ideal for pitched roofs. The rainwater and storm water collected onto the roof drains into these gutters which is then disposed off through downpipes and drain pipe connectors which lead to the central drainage and sewage system. Gutters are an inexpensive solution but need to be cleaned regularly to prevent blockage.

2. Internal drains - If your house has a flat roof, internal drains are an inexpensive solution for roof drainage. Draining in the lower elevations of the roof, internal drains connect to a downpipe which drains the water to a tank or reservoir. Inner drains often have protective barriers to prevent debris from flowing into them. These pipes do not freeze in the cold weather either.

3. Scuppers – When it comes to choosing rainwater and stormwater management systems for flat enclosed roofs, parapets and terraces, scuppers are also a lesser-known choice. Scuppers are holes cut into the edges of the roof to drain the water through downpipes. To direct the flow of the water, rubber or metal seals may be fixed at the rim of the holes. The downpipes collect the water and drain it into underwater tank or reservoir. While scuppers do not need intensive maintenance, the downpipes must be checked once in a while to prevent clogging.

4. Siphonic drainage - One of the most sophisticated drainage systems for houses, these enable the roof drainage to function at full capacity. The siphonic roof drainage system does not use too many pipes and instead sucks the water from the roof through a combination of gutters and pipes. The efficiency of siphonic drainage systems is the highest, which also makes it the system of choice for large buildings.

How Does Siphonic Drainage System Work

The water logging of building roofs can be damaging to the structural integrity of buildings. This is why it is important to make provisions for ensuring that there is effective drainage of all the accumulated water. This must be especially taken care of in cases of flat roofs in low rise and high rise buildings. A roof drainage system is instrumental in enabling the flow of accumulated water from the roof and preventing seepage, water logging, etc.

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. This downpipe carries off the water from the roof to the ground, to a tank or a sewage line. However, traditional roof drainage systems have a fundamental problem in that they carry air along with water which prevents the system from functioning at full efficiency and only carries limited amount of water in the pipes. It is for this reason that a siphonic roof drainage system is being increasingly favoured for new constructions.

In siphonic roof drain systems, provision has been made to ensure that the downpipes can carry full load of water and not air. This is done by altering the design of the drainage system. An insert is included in the system through pipes of smaller diameters, which restricts and blocks the entry of air in the pipes, leading to negative pressure, and thereby ensuring smoother and faster flow of water down the pipes. The entire system of siphonic roof drainage has several collector pipes with the air-restricting function which together collect the rainwater which is accumulated in a tank at atmospheric pressure.

Since the pipes of a siphonic roof drainage system function at full capacity, fewer down pipes and outlets are required for the complete drainage of even large areas. This also frees up the space on the roof, especially in the case of surface pipes. Given that the pipes are smaller in diameter as compared to pipes in conventional systems, siphonic roof drainage systems also require fewer materials for the installation of the complete network.
