Ashirvad Siphonic Roof Drainage – Intelligent Rainwater Solutions for Expansive Roof Areas

Unlike gravity systems, siphonic drainage eliminates the need for sloped pipes and multiple downpipes, offering greater design flexibility and cost efficiency.

Yes. Akasison is well-suited for high-rise structures and reduces the requirement for vertical drainage stacks.

Yes. With appropriate hydraulic design modifications, it can be integrated into existing buildings.

The system utilizes durable HDPE piping with electrofusion joints for long-lasting, leak-resistant performance.

No. The high-velocity water flow supports self-cleaning action, minimizing routine maintenance needs.

Installation must be carried out by trained professionals. Ashirvad offers technical assistance and training to ensure proper execution.

Use certified hydraulic design, approved Ashirvad components, and proper electrofusion procedures. Conduct inspections and train installation teams with Ashirvad’s support.

Avoid mixing siphonic and gravity systems, altering layouts without approval, using incompatible materials, ignoring air-blocking requirements, or skipping proper fastening and support.

Key design considerations include roof area, rainfall intensity, outlet positioning, pipe sizing, and system hydraulics. Ashirvad siphonic roof drainage solutions are designed using engineered layouts to ensure full-bore flow, structural safety, and reliable performance in large-scale infrastructure projects.

Negative pressure enables the system to operate under full-bore flow, allowing rainwater to be drawn rapidly from the roof without air entering the pipes. Ashirvad siphonic systems use this principle to achieve higher flow rates and faster water removal compared to conventional gravity-based drainage.

Siphonic roof drainage systems are ideal for buildings with large roof areas such as airports, malls, warehouses, industrial facilities, stadiums, and commercial complexes. Ashirvad siphonic solutions are especially suited for projects that require efficient water removal, design flexibility, and minimal visual impact.
