Regent’s Park, London

The Construction of a New Borehole

The Royal Parks commissioned AWS to provide a suitably sized borehole for a number of applications in Regent’s Park.

The Park had recently procured a grant from the Sports Council to upgrade the 40 or so sports pitches in the Park which are immensely popular throughout the year. Having spent a significant amount of money on the upgrades including an irrigation system, Royal Parks wished to create their own resource for watering the grass, and which would not place a burden on the local potable water supply. Additionally such an increased use of mains water would be very expensive.

Together with AWS staff the Park’s Managers made an estimate of the total annual volume which might be available for the following additional uses:

  • Filling of the Lake in the Park
  • Watering of the famous Rose Garden
  • Irrigation of the plant seedlings in the Nursery
  • Replenishment of water for the numerous fountains

The borehole was drilled and constructed with very little disturbance to the public rights of way, without noise nuisance or other interference with the day-to-day business of the Park, and is now fulfilling the uses for which it was intended.

AWS took responsibility for the appointment of the Contractor and the supervision of the works.
