A windmill is a watering source where water is pumped through wind power. It can retrieve water from wells, boreholes, ponds, fountains and rivers and this pump can also be used for draining swamps. It is mostly used for the provision of water for domestic use or to provide water to live stock. Windmills are to this day commonly found throughout the South African country and in neighboring countries.
A windmill is relatively easy to install and through the years it’s proven itself to be a trustworthy watering source. They have a very long lifespan and the maintenance is quite low and can be done on your own without contracting a company that will cost you a lot of money. It does not make use of fuel, and does not contribute to air pollution and is therefore considered to be green technology.
The main disadvantage of a windmill is that it only work when the wind blows. But the wind is not always equally strong and reliable in all areas. Windmills can be quite noisy and they are sometimes unsightly.
The first windmill in South Africa was known as a Halladay Standard. It was a wooden windmill and was erected by a farmer from Hopetown, Mr. Du Toit. One of the earliest ilustrations of a Halladay Standard windmill that existed in the country was dated 1884 on an ostrich farm.
In 1888 an Aeromotor company from the US started making windmill with steel blades which was bent in order to develop more power. In 1893, this type of windmill was imported into South Africa. That windmill cost between R50 and R300, could retrieve water 30 – 90m from the ground and would deliver 177 m3 water daily.
Because of global warming the water levels is much lower than back in the days and therefore nowadays a windmill can retrieve water from any level between 30m up to 200m deep.
