Over 70 years ago The Forest of Dean was designated as a National Forest Park; the first in England, offering a wealth of natural beauty and outdoor pursuits. Early last year the tranquillity was interrupted when 45 fire fighters were called to the forest because together with water authority engineers, a catastrophic DN900 high-pressure pipeline failure had accrued at the Wyelands intake pumping station, leaving many households without drinking water.

The contractor charged with the refurbishment faced numerous challenges including the replacement of 40 year old valves having imperial dimensions and working within restrictive confined spaces.

The current valve framework manufacturer was unable to accommodate the request for non-standard design configurations and therefore T-T’s valve division Aquaflow were approached. After meticulous technical discussions a contract was secured for the supply of several replacement valves.

Aquaflow therefore supplied three DN400 engineered high-performance non-slam style checks rated to 40 Bar having imperial BS10-H flange drilling, integral bypass arrangement and non-standard face-toface dimensions in order to negate costly pipework modifications. Accompanied with a DN900 wedge gate valve having a by-pass assembly rated to 25 Bar, complete with remote electrically actuated operating equipment fabricated in-house to suit site specific requirements. The valves were manufactured in robust ductile iron with all coatings and materials having WRAS approval to ensure the drinking water network does not get contaminated.
