CONCRETE WATER DISPOSLA SYSTEM ABL-900
WHAT FOR
Concrete water disposal system ABL-900 is designed to catch and dispose of surface, storm and melt water from improved surfaces like motorways, terminal bays and airfields.
WHAT OF
The system includes:
- The drain trough – a concrete cast serving to collect surface (rain and melt) water along the length and its subsequent diversion;
- The sand trap – a precast collecting chamber serving to settle and collect particulate matter (sand, soil and coarse litter) from surface drainage in diversion;
- The inlet grate – a removable part of the drain trough, installed on to the structure of the trough (sand trap) to let the water in and through. The grate is made of cast iron;
- Trash collector;

The troughs and sand traps are manufactured at hydraulic section widths (DN) of 100 to 550 mm.
The cross-section of the fluid ends of the troughs and sand traps may be rectangular, trapezoid, parabolic or otherwise specified in the technical documents.
The drain troughs are cast in lengths specified in the project, but at least of 1000 mm.
