Glencorse reservoir was built in 1822 by the Edinburgh Joint Stock Water Company and at a cost of £43,000. The engineers were Telford and Rennie, but the works were carried out by Mr Jardine, of Edinburgh. Situated 8.3 miles (13.4km) by road and 9.5 miles (15.3km) by pipeline from Castlehill Reservoir, Edinburgh (NT27SE 492), it measures 52 acres (21ha) in area and up to 62ft (18.9m) in depth. It is situated at an altitude of 730ft (223m) OD, drains an area of 3694 acres (1496ha), and has a capacity of 359,373,000 gallons (1,633,709,658 litres). The cost of the works proved greater than was anticipated.
The level of the reservoir was raised by 4ft (1.2m) in the years after 1846.

This reservoir forms a major element of the Pentland Works of the Edinburgh water supply system. It was formed by constructing an earthen dam (termed an 'embankment') across Logan Burn or Glencorse Burn, a tributary of the River North Esk. Due provision was made for the supply of compensation water to the numerous mills on that river.
Unlike other schemes of this nature, no measuring house was apparently provided.
