The history of Edinburghâ€™s water supply is long and fascinating. As the South Loch (todayâ€™s Meadows) dried up, supplies from beyond the city limits were sought, first in the 18th century in the area of Comiston Springs and then in the Pentlands in the 19th century. These involved several on the northern edge of the Moorfoots. Talla followed in the early 20th century, to capture the abundant rainfall of upper Tweeddale, others nearby somewhat later. The huge schemes had long ceased to be exclusive to the city but involved the whole region.
