up with fresh water using a windpump. This arrangement was put in place following research by the Landscape Architect Fraser Borwick, which revealed that ground water had historically been extracted to supply various industrial processes using wind power. After checking the borehole results of the Jubilee line construction team, it was established that large amounts of potable water were available, and a borehole 80 metres long was sunk into the ground. The borehole is lined for 60 metres, and the bottom 20 metres is into chalk. The investigation of how best to keep the lake topped up with fresh water was the result of some damage to the lining of the old dock during construction works in the 1980s. Another solution considered involved securing a water supply from the flooded tunnels of London Underground, but this was considered too risky.
