Irrigation Water Supply Borehole
Chadwell Heath, London

Envireau Water recently developed and licensed a new abstraction borehole at Cranfield Golf Academy in Chadwell Heath, Essex. The new borehole will be used to supply all the irrigation water required for a brand new golf course, currently under construction.

The borehole was constructed to a depth of approximately 107.5m to target the major Chalk aquifer at the site. During construction, the formations above the Chalk proved to be unstable, making construction of the upper part of the hole particularly challenging. Envireau Water worked closely with specialist water well drillers WB AD Morgan to ensure that the most appropriate methods of construction were employed and the integrity of the borehole was assured.

A programme of targeted acidisation was carried out to maximise borehole efficiency. Envireau Water provided a high level of support during the design and execution of the acidising programme in order to reduce the risks of developing a hydraulic connection between the chalk and the overlying deposits.

Scientific yield testing demonstrated that the borehole is highly efficient and easily capable of supplying the 45,000m3 of water per year for irrigation without causing a detriment to the local water resources and any nearby abstractors. Indeed, there should be plenty of scope for increasing the rate of abstraction in the future if so required.
