The information following is from documentation I received from 1935 on completion of Glenafton Reservoir. I have amended it as far as possible to simply give the facts of why a reservoir was needed, costs, problems encountered and the areas to be supplied.
Ayrshire was seen as a milk producing county with approximately 1750 registered dairies. The milk yield was given as over 30 million gallons a year. The water requirements for dairy farming alone was one and a half million gallons. The water requirements for a population of 125000 is not given but the difficulties of provision for a widely scattered population was considerable.
By 1935 there were 36 different water sources including those from outside Ayrshire. The total amount of water required for Ayrshire was a daily supply of 6.5 million gallons and the supply available 6.8 million gallons.
Most of the water supply was from Loch Braden but overall the quality and quantity left a lot to be desired and storage was limited. Improved sanitation and higher rates of consumption put the water availability under threat in the summer months.
The Glenafton proposal would add 2 million gallons to the daily supply with improved delivery. Glenafton was chosen after consultation with engineers as being the most suitable and convenient of the choices available.
