Rainwater drainage systems play a crucial role in ensuring both the environmental sustainability and structural safety of buildings.
At ARKATUN Engineering, our rainwater collection and drainage systems are designed based on the principles of hydraulic balance, environmental protection, and energy efficiency.

Our design process includes detailed analysis of:

• Local rainfall intensity and roof catchment areas,

• Gutter and downpipe capacity calculations,

• Flow rate, slope, and pressure loss optimization,
  all performed in accordance with TS EN 12056-3, DIN 1986, CIBSE Guide G, and ASHRAE Drainage Standards.

We develop gravity and siphonic drainage systems, as well as rainwater harvesting and reuse solutions that integrate seamlessly with building design.
Advanced filtration, sedimentation, and treatment units are utilized to enable rainwater recovery, supporting sustainability while reducing operational costs.

All our projects are modeled in 3D and BIM-based platforms, ensuring coordination between architectural, structural, and mechanical disciplines.
This approach eliminates on-site errors and guarantees a safe, efficient, and long-lasting rainwater management system.

At ARKATUN, our goal is not merely to discharge water but to create innovative, eco-conscious systems that preserve natural resources and contribute to a sustainable built environment.
