It is a high-performance drainage solution that uses negative pressure to rapidly remove rainwater from large roof surfaces with fewer, smaller pipes.
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.
