Our Solutions
Complete System
We are capable to provide the full rainwater complete system with high quality material which including the Conventional Rainwater Drainage system, Siphonic Rainwater Drainage system and Rainwater Harvesting for any projects.
Sustainability
The implementation of fully automatic rainwater harvesting system to make the collection of rainwater easier to reuse in irrigation systems, WC System & other non-drinking uses.
Smart Backup System
Our system is perfect cooperation in terms of pipework’s' design and supply which capable to provide a hybrid backup system for any buildings by our BESSTEM Conventional Rainwater Drainage System.
THE ADVANTAGES OF 
Material Saving
BESSFLOW -- RAINPLUS requires a lower number of roof outlets and allows a substantial reduction in pipe diameters and quantities when compared to conventional systems.
Space Saving
The roof outlets are connected to single horizontal collector pipes that are fitted without gradient fall and the downpipes are positioned anywhere along the building perimeter, thus avoiding any interference.
High Performance
When in operation drainage pipes flow at 100% full bore and high velocity. Therefore draining speed is greater resulting in the self-cleaning action of the pipework.
Time And Labor Saving
Construction programmes are accelerated due to reduced installation times moreover. Less groundwork is required due to the reduced number of embedded pipes.
Design Flexibility
Complete control over downpipe location and absence of embedded pipes causes increased design flexibility of the siphonic system.
System Assurance
The system is covered by warranties which guarantee against defects in design, installation, materials and workmanship up to Ten (10) Years upon commissioning
THE ADVANTAGES OF USING THE HDPE SYSTEM
Wide Range Of Fittings
Wide range of diameters from DN 50 mm to DN 315 mm, available in SDR 26 and SDR 33 ; included access pipes, elbows, reducers and
reduced branches.
Extreme Temperature
Resistance to intermittent discharges at temperatures as high as 950C. High resistance to extremely rigid temperatures as low as -400C.
Durability
Durable, excellent abrasion resistance and mechanical strength. The pipes are stabilized to reduce dimensional variation and contain carbon black for UV light resistance.
Highly Versatile
Possibility of prefabrication to reduce assembly time on site possibility of creating special pieces for particular applications and solution.
High Chemical Resistance
High chemical resistance to substances dissolved in civil and industrial waste waters.
Compatibility
Wide range of transition fittings for connection to other waste systems such as Cast Iron, PE, PP, PVC.
TYPE OF INSTALLATION
HDPE PIPE WELDING INSTALLATION
Manual Butt-welding
The roof outlets are connected to single horizontal collector pipes that are fitted without fall and the downpipes are positioned anywhere along the building perimeter, thus avoiding any interference.
Machine Butt-welding
Butt-welding machines could weld up to 315 mm diameters. This process is extremely useful for the prefabrication of system parts that are then installed and connected on site using the other numerous jointing methods.
Electrofusion Couplings
Thanks to the use of electrofusion couplers that are available in 50 mm diameters to 315 mm diameters, all system parts can be prepared. A method that guaranteed rapid, uncomplicated and extremely reliable welding against any installation situation.
