Safety and durability were of paramount concern, along with engineering design expertise that could ensure there was a near complete elimination of significant debris within the ring main.
We knew that any material used in the proposed system would need to be extremely hard wearing and a temperature resistant alloy. Gunmetal cast material was the ideal solution, so we constructed hydrant housing made from this alloy, an essential piece that was vital for success.
In order to eliminate debris in the ring main and enable a constant flow of water when required in emergencies, we installed the uniquely designed Knowsley SK ‘8 port’ flushing. It’s a drain valve at the base of the hydrant which enables the valve to remain closed and debris free, but when opened, provides enough space for waste to be dispersed.
