The Board of Magalies Water was originally established by Government Notice 234 of 1969, with various subsequent amendments to both its name and its area of supply. Magalies Water currently operates in terms of the Water Services Act, Act 108 of 1997 as amended.
Initially the Vaalkop Water Board was established mainly to supply the needs of platinum mines in the Rustenburg- and Thabazimbi areas. For this purpose the Vaalkop Purification Plant was constructed next to the Vaalkop Dam with a capacity of 18 Ml per day. Over time the capacity was extended to progressively cater for the needs of other consumers, such as Sun City, more mines, industries and various communities in the then Boputhatswana and RSA. During 1999 the Plant was again extended after negotiations with Rand Water to supply the rapidly increasing water demands of the Rustenburg region.
The Board systematically also became involved in other Purification Plants on the request of the Department of Water Affairs and Forestry and eventually took over and upgraded the Klipdrift- and Wallmannsthal Purification Plants. After negotiations with the De Beers Consolidated Mines the Board also took over and upgraded the Cullinan Purification Plant in 1993.
During 1996 the Board became involved in retail water supply services when it was requested to operate, maintain and supply the retail services in the Mankwe, Moretele and Odi areas of Bophuthatswana. To date Magalies Water has significantly expanded retail services throughout its area of operation. The Board of Magalies Water also took a strategic decision during 2003 to regard these services as part of its primary activities following the promulgation of the Municipal Structures Act and Municipal Systems Act and to further enhance the services to the benefit of communities.
With the changes in legislation during 2000, which transferred the status of Water Services Authorities to Municipalities, the Board started negotiations with various Metropolitan-, District- and Local Municipalities regarding Water Services Provider agreements. Agreements and/or Memoranda of Understanding have been concluded with most of the Municipalities for the provision of Water Services to them, i.e. the City of Tshwane Metropolitan Municipality, Moses Kotane Local Municipality, Madibeng Local Municipality, Moretele Local Municipality and Rustenburg Local Municipality.
Currently, Magalies Water is a regional operator, providing water services across various provincial and municipal boundaries in Gauteng, Limpopo, Mpumalanga and North West Province.
