screen and consists of longitudinal rectangular ribs (rods) and horizontal beams

(wires) of Trapezoidal cross-section.

The jacket ribs shall contact the pipe base raising the horizontal beams above the

base of the ribs to allow water flow between the jacket and the pipe base.

The Jacket is position on to pipe base so that the ribs are located at the perforations

edges and not across the middle of the perforations.

onto the pipe base at 45° angles and at distance 0.75m from the bell end 0.5m from

the spigot end.

The jacket diameter should be less or flush with the bell diameter
