  1900-1909  

1901 Johannesburg Water Supply: In September, the Town Council (which was appointed in May of that year), suggested that a public body representative of the mining interests and the various municipal bodies along the Rand, should be established to obtain water in bulk, which would be supplied wholesale to the mines and public bodies, who would in turn supply water to individual customers. (Ref 11).       
1902 Johannesburg Water Supply: The Rand Water Board was established with an area of supply covering 4548 square kilometres – about one quarter of the area supplied by the board today. (Ref 11).       
1902 Most severe snowstorm in memory of South Africa. Sow 1.5 m deep in East Griqualand where 13 000 sheep froze to death on 12 June 1902. (Ref.10).      

1902

Johannesburg Sewerage: A survey of the insanitary area carried out in August 1902 gave the area as 172 acres (69,9ha). The area which included the Brickfields (later Burghersdorp) and a small part of Fordsburg had a population of 5 651. (Ref 11).       

1902

The first recorded use of chlorine on a permanent basis for the disinfection of water was in Middlekerk, Belgium, in 1902. This fundamental process is still used today, (WRC - History of Water Treatment)

1902

Pretoria water supply: The  Fountains Valley  water scheme was supplemented in 1902 with a 36 inch (900 mm) diameter concrete aquaduct laid by the British Army shortly after the Anglo Boer War and the 3 million gallon (13.6 Ml) Findley Reservoir built on the southern side of the railway station. This system ensured that the suburbs of Arcadia, Muckleneuk, Sunnyside, Roberts Heights (the current Voortrekkerhoogte), Innesdale and other proposed residential areas could be supplied with water. (Ref.7)      

1903

Johannesburg Water Supply: The first chairman of the Rand Water Board was Lieutenant Colonel Fowke. (Ref 11). 

1903

Since 1903, Rand Water has been a bulk water supplier to the Gauteng area. In recent years, we have responded to social and political change by choosing to operate beyond our traditional role as a bulk supplier.

1903

Johannesburg Sewerage: In 1903 under a new town engineer, DC Leitch, formal control of sewering Johannesburg reverted to the Town Council. (Ref 11).       

1903

Johannesburg Sewerage: In January 1903 complaints were received of rats dying in large numbers in the Market buildings and at Henwood’s Arcade. (Ref 11).      

1904

Johannesburg Sewerage: In March 1904 an outbreak of bubonic plague erupted in the insanitary area. (Ref 11).       

1904

Johannesburg Sewerage: The Council wanted to use the Southern portion of the farm Klipspruit for the purpose of sewage disposal, but by 1904 it could not gain occupation because of its objections from adjacent land owners. The Government decided to appoint a commission of enquiry into the matter. (Ref 11).       

1903

The oldest evidence of a sewerage system in Pretoria is shown on a plan drawn up in 1903 by the Sanitary Engineer E.S.Prentice A.M.I.C.E. of the Central South African Railways (CSAR) Administration. It shows a system serving the Railway Depot, Hospital, Goal, Military Barracks and proposed Railway Town, all situated near the present Pretoria Station. (Ref.5)      
1904 Construction of the Hely Hutchinson Dam in the Disa River on Table Mountain. (Ref.1.)
1904 Johannesburg Water Supply: The chairman of the Rand Water Board was W. St John Carr, who resigned as Mayor of Johannesburg, to accept this post. (Ref 11).       
1904 In the year 1904, when the population of Pretoria was 36 700, the Town Engineer H.D.Badcock submitted the first plans for a sewer reticulation system for Pretoria and a purification works at an estimated R 740 000. His proposal were not fully accepted and only four purification units were constructed between 1913 and 1920 to the design of Town Engineer F.Walton Jameson. (Ref.5)      
1904 Johannesburg Water Supply: The Braamfontein Estate Company became the Transvaal Consolidated Land and Exploration Company Ltd, which was responsible among other things for the establishment of the townships of Parkview, Parkwood and Saxonwold. (Ref 11).       
1904 Cape Town water supply: The Final Report on Investigations by the Joint Water Committee of Cape Town, dated 15 December 1904, proposed the Schaufraam Dam as part of the French Hoek Water Scheme in the Berg River Hoek Watershed. The cost estimate for the dam was 930,000.00 sterling pounds. Go to  Cape Town Water Supply History for more information.

1905 Johannesburg Water Supply: In April, the board took over the assets of the various water undertakings. (Ref 11).       
1906 Cape Town water supply: The Water Supply Report, submitted to the  the Suburban Joint Water and Drainage Committee of Cape Town by Mr Thomas Stewart, dated 23 January 1906, indicated the Key Plan for water supply to the southern suburbs. This plan included the Wemmershoek Dam (construction completed in 1957), the Steenbras Dam Water Scheme (inaugarated in 1921) and the Berg River Hoek/Warm Berg water scheme (the Schaufraam Dam), which is at present under construction as part of the Berg Water Project. Go to  Cape Town Water Supply History for more information. report2.jpg (98296 bytes) report21.jpg (43676 bytes)  
1906 The "Pretoria Sewage Disposal Commission" was appointed on the 26 th day of October 1906 under the Governmental Notice No.1105 of 1906. (Ref.5)      
1906 The Pretoria Council now propose to sewer the town, to conduct the sewage by gravitation through Daspoort, to treat it in septic tanks and filters on the site proposed to be exproprated, and to discharge the effluent from the filters into the Aapies River or to supply it to irrigation. The details of the scheme are set out in the Town Engineer's Report, dated 1 st November 1904, and the Supplementary Note to that Report, dated 12 th November 1906. (Ref.5)      
1907 It is interesting to note that purification works (for sewage in Pretoria) were built during and just after the Anglo-Boer war at various military camps, including Voortrekkerhoogte, then known as Roberts Heights. Two biological fiters constructed there in 1907 are still functioning satisfactorily. (Ref.5)      
1908 Construction of the Maquassie Dam in the Maquassie River near Wolmaranstad. (Ref.1.)

1908

Johannesburg Sewerage: By 1908 the volume of sewage being spread over the land at Klipspruit was 45 00 000 litres per day. In the same period, due to depression in the labour market, the Sewage Committee decided that certain sections of the sewerage and storm water undertakings would be carried out departmentally using unskilled labour (Ref 11).       

1908

The Bongola Dam (Bonkolo) about 5 km from town on the Dordrecht road, is one of  Queenstown’s main sources of water.  The wall was begun in 1905 and was for years the largest concrete dam wall in South Africa.

1908 Johannesburg Sewerage: In order to eliminate the pumping station at Natal Spruit, which handled flow from the south eastern drainage basin, a subsidiary eastern drainage basin, a subsidiary outfall sewer was built from there to Ophirton in the south western basin      
1908 Johannesburg Sewerage: A Court injunction was granted against the Council prohibiting the depositing of slop water on the site after 1 August 1908. (Ref. 11).       
1908 Johannesburg Sewerage: After 1908 property owners were enforced in terms of the Drainage and Plumbing By-laws to connect the sewer system      
1908 Port Elizabeth water supply:  The earliest Water Workshop was part of the Municipal Depot (or stables) in the Baakens Valley. After the flood of 1908 the depot was relocated to North End and became known as the Harrower Road Depot. The Water Workshops were on the west side of the depot in Connaught Avenue. In 1991 and 1993 the Water Distribution and Water Installation Workshops, respectively, moved to the newly established Burchell Depot at Hunters Retreat. The new premises were designed around the needs of the workshops and have proved to be a major improvement. The workshop in Cuyler Street, Uitenhage have been retained. (Ref.8)

1910

My grandfather, Harry Herbert Roe, was Superintendent of waterworks in Pretoria .  He joined the Pretoria Council around 1910, and worked under George Storrar, who was Town (City?) engineer.  He then moved to Durban council for a while, and returned to Pretoria , where he became Superintendent under City Engineer Louis de Waal.  Louis was married to Genl Louis Botha's daughter, and i remember her visiting us, complete with gloves and hat. As I recall, during my grandfather's time, Pretoria 's water was brought from Fountains Valley , and he had a great deal to do with the pumping stations at Fountains - whether their initial construction, or perhaps expansion of capacity, I don't know. I also seem to remember he was involved in the initial stages of the Daspoort treatment plant. I think I was destined to be involved in water, as my late father in law - Bill Murray, was with DWAF for his whole working career.  he was a civil engineer, and involved in many major dam and irrigation projects in the country, including the raising of Hartebeestpoort Dam wall, Loskop, Breede Rivier and Hendrik Verwoerd Dam. (Ref.10)  

1910

The oldest main sewer in Pretoria is probably the egg shaped sewer of 21 inches x 15 inches (533 mm x 381 mm) which was constructed alongside the Steenovenspruit before 1910. (Ref.5.)      

1910

Johannesburg Sewerage: Legal proceedings were instituted against the Council by adjacent land owners, the basis of the complaint being “alleged nuisance” at the Klipspruit Sewage Farm. 

1910

Johannesburg Sewerage: Although sewage was first received at the Klipspruit works in 1907, it was not until 1910 that the first proper treatment plant was constructed and put into service. (Ref 11). 

1910

Construction of the De Villiers Dam in the Disa River on Table Mountain. (Ref.1.)

1910

A diversion and storage dam had been constructed in Fairy Glen, followed by the completion of a filtration and chlorination plant in 1936.  (Ref 17)

  1911 Construction of the Loxton Dam in the Soutpoort River near Loxton. (Ref.1.)
1911 Johannesburg sewerageIn 1911 a sewer untake for night soil was constructed at Bez-Valley. From here the sewage was pumped to the Main sewer at lower Ross Street and then it flowed by gravity via subsidiary outfall and main outfall to Klipspruit. The length of sewers including outfalls in the town at this stage was 120 km.  (Ref.11.)      
1913 Four purification (sewage) units for Pretoria were constructed between 1913 and 1920 to the design of Town Engineer F.Walton Jameson. (Ref.5)      
1913 Johannesburg Sewerage: When the Government passed the Native Land Act of 1913 it had the effect of driving thousands of black [South Africans] from the rural areas to the big towns. As a result of this influx, the Government urged the Council to provide more municipal locations. (Ref 9).       
1913 Land Act removes the right to own land from black South Africans. Since access to water was tied to land this in essence removed the right of access to water for productive purposes from black South Africans.
1913 The first large-scale irrigation work in the Sundays River Valley (and indeed in South Africa) as the Korhaans Drift weir completed at the end of 1913.  (Ref 14)      
1913 For more than 30 000 years, the Khoi people had relied on water flowing off Table Mountain, in a place they knew as Camissa - "place of sweet waters'.  Cape Town's water as a municipal utility began with Jan van Riebeeck establishing a Vereenigde Oost-Indische Compagnie (VOC) station in Table Bay in 1652.  Table Bay was chosen over the more sheltered anchorage Saldanha Bay because of Camissa. (Ref 25)      
1914 Construction of the Vaal Barrage in the Vaal River near Vanderbijlpark. (Ref.1.)

1914

With the outbreak of World War 1 in 1914, the (Union of) South Africa's Government drilled a series of boreholes along the Auob to provide their troops with water in case South Africa wanted to use corridor to invade South West Africa. Guards were recruited mainly from the local community and hired to protect and maintain the boreholes. They were permitted to settle next to the holes with their families and livestock. This corridor was never used to invade South West Africa and the borehole. (Ref

 

   
1917 The Sundays River Irrigation Board was established with the sole purpose of constructing what was soon named Lake Mentz (Darlington Dam)after the Minister of Lands, Col H Mentz.A loan was provided by the State to construct the dam and the repayment of the loan was the responsibility of the irrigators by the imposition of a canal levy by the irrigation board. The Sundays River Project as it was then known, was considered unique by virtue of the fact that almost the entire area of irrigable land was controlled by companies and not by private individuals, and that the existing irrigation works, weirs, canals etc. had been constructed by the companies themselves.  Lake Mentz would be the second largest dam after the Hartbeespoort, which was also being constructed at the time. (Ref 23)

 

   
1918 Johannesburg Sewerage: The Council resolved to concentrate on a new housing area on the old sewage tipping site known as the Newlands Location. (Ref 9)

1920

A chemist (M.Lundie) for the Pretoria wastewater purification works (the first Chemist for a wastewater purification works in South Africa) was appointed by the Town Engineer F.Walton Jameson of Pretoria. (Ref.5)      

1920

Construction of the Lake Mentz later renamed as the Darlington Dam. Sundays River. Eastern Cape.

1921

Work began on the Athlone treatment plant and 240 km of sewer reticulation and was completed 2 years later.  The Athlone works incorporated state-of-the-art technology for the first time - "Imhoff' settling tanks and brushwood filter beds.  The works have since been repeatedly enlarged, roughly every decade and after the most recent upgrade completed last year, now handles 105Ml a day on average.  The treated effluent released is so clean that waterbirds, which have not been seen for decades on the Black River, have returned. (Ref 25)

1921

The "Africa District" of the Institution of Municipal and County Engineers was formed on 6 June 1921 in Johannesburg. (Ref.2.)

9 March 1921

Inauguration of the Steenbras Water Scheme. Steenbras River. Western Cape. (Prince Arthur of Connaught). Engineers in charge were Mr.D.E.Lloyd-Davies and Mr.C.R.Barlow.

1922 Nqweba dam (prevously known as the Van Rynevelds pass dam) outside Graaff-Reinet was one of the  first large dams to be constructed in South Africa.   A start was made on the foundations of the dam in July 1921. Excavation work was carried out in four sections: left flank, base excavation, river section and right flank. About 27 432 m of soil were taken out by means of donkeys and scrapers.  The dam now forms part of the Camdeboo National Park, and these days it is more noted as a tourist attraction than a main water supply (Ref.7)      
1923 Pretoria water supply:  Roberts Heights (the current Voortrekkerhoogte), which is situated in an area higher than the Fountains Valley, was supplied with water through a 12 inch (300 mm) pipeline driven by steam engines. The steam engines (the first municipal pump station in Pretoria) were replaced with electric motors and the newly erected Muckleneuk pump station situated on the eastern side of the Fountains Road was also equipped with electric motors in 1923. (Ref.7)      
1923 Pretoria water supply:  The daily water consumption was 4.47 million gallons (21.48 Ml) which was virtually the supply capacity of the Fountains in 1923. (Ref.7)      
1924 Johannesburg Water Supply: The Town Engineer, Mr GS Burt Andrews, mentioned that the greatest quantity of water taken in one day was over 6,3 million gallons on the 18th January. (Ref 9).       
1925 Johannesburg Water Supply: In June, Mr GS Burt Andrews, the Town Engineer, gave a radio talk on the water supply and its distribution in Johannesburg in which he described the extent of the distribution system. (Ref 9).       
1925 Hartbeespoort Dam:  The first foundation concrete was placed on 29 July, and by September 1922 the wall was two metres above the riverbed. By April 1923 the wall was completed, and only the finishing of the parapets and crest road remained. During the construction phase the dam impounded the floods of 1922/23. The whole scheme, including the canals, was completed in 1925. 

The dam was filled on 11 March 1925, and a maximum flood of 2 700 cusecs passed down the spillway on 26 March of that year. After completion, 97 farmers and 65 lessees made use of the water from the Hartbeespoort Dam. (Ref 15)

  1926 Construction of the Loch Athlone Dam in the Jordaan River near Bethlehem. (Ref.1.)
1927 Pretoria water supply:  As a result of the limited  capacity of the Fountains of 5.06 million gallons per day (23 Ml/day) and the increasing demand for water, Messrs George A Storrar and F Walton Jameson were requested in November 1927 to evaluate various projects and continue with the planning of a supplemental water scheme. (Ref.7)      
1928 March 1928 saw Lake Mentz overflowing for the first time. (Ref 14)

1928 Johannesburg sewerage:  On 5 September 1928 Johannesburg was elevated to the status of a city. All the residential suburbs on the northern side of the watershed were still served by the primitive night soil pale collection system while bath water was either disposed of via French drains or conservancy tanks which were emptied on a regular basis.  (Ref.11.)      
1929 Johannesburg sewerageThe first of the northern basins to be tackled was the eastern basin which drained to the proposed Bruma Works in Kensington. In 1929 Dr.E.J.Hamlin had initiated construction by contract just prior to becoming City Engineer. The surrounding residents were not very happy about a sewage purification works so near to them and at one famous public meeting Dr.Hamlin drank a glass of purified effluent to demonstrate his complete faith in the stone trickling filter system.   (Ref.11.)      
1929 Pretoria water supply:  In 1929 the Council instructed the Consulting Engineers to commence with an in-depth study of the Rietvlei-Grootfontein scheme and the drawing up of a report to be submitted to Parliament for the approval of the dam construction with purification works and the collection of water from the Rietvlei Fountains and Grootfontein. The proposal was not supported by the Department of Agriculture. (Ref.7)      
1929 Pretoria water supply:  The run off of the Hennops River was measured from 1904 to 1927 at a measuring station at Zwartkop near Wierda Bridge and the proposed construction of Rietvlei Dam would have neglible influence on the Hartebeespoort Dam inflow. As a result hereof, Parliament approved the scheme in 1929. (Ref.7)      
1929 Pretoria water supply:  During 1929 the Council decided to purchase the water rights of the Rietvlei dolomitic fountains and Grootfontein as well as the property on which the proposed Rietvlei Dam would be constructed. The farm was approximately 3 500 morgen (3 000 hectare) in extent. (Ref.7)      
1929 Johannesburg sewerage reticulation and treatment: Prior to the 1930’s, the Klipspruit Sewage Farm was the only facility Johannesburg possessed for handling its wastewater.  Klipspruit served the whole area, much of the areas draining to the north being served by recourse to the pail system. Dr E J Hamlin, the then City Engineer, gave priority to sanitation and sewage treatment plants were established in four of the north flowing stream valleys.  The new works were named in alphabetical order according to Harold Wilson; Antea-the first; Bruma-a wet place in the Bible; Cydna- after the river Cydnus (on which the ancient city of Tarsus was sited and which flowed into the Mediterranean Sea at a point about 75 miles north of the northernmost tip of Cyprus); and Delta the fourth works after the 4th letter of the Greek alphabet. (Ref.6)      
1929 The storage potential of the Riviersonderend was realized as far ago as the 1800s, but it was the Irrigation Department who started the first serious investigations into the possibility of a scheme here in 1929. This mountainous region has one of the highest rainfalls in South Africa (as much as 5 000 mm/year). A provisional dam design had actually been completed by 1952, and by 1964 the focus has zoomed in on the Theewaterskloof as the best storage site available. When the Greater Cape Town again started experiencing water shortages following the construction of the Wemmershoek Dam, it was de-cided to go ahead with the Riviersonderend-Berg River scheme. The scheme would not only supplement water supply to Cape Town, but would also be used to provide irrigation water during the dry months to farmers in the Boland. The project was described as „one of the most impressive civil engineering projects of the 1980's

1933 The wastewater flow for Pretoria averaged 9 megaliters per day (Ref.5)
1934 Pretoria water supply:  Mr Chas E. Stewart, Chartered Engineer was commissioned to plan and design the Rietvlei Dam. The construction of the dam and purification works commenced in 1930 under the supervision of Mr B.G.Twycross who was appointed as the Resident Engineer. This work was carried out thoroughly and conscientiously and the project was completed 4 years later in 1934. Most of the dam wall pitching, stone walling and the dam spillway was constructed by hand due to the shortage of construction machinery. Material for the earth fill wall was conveyed by ox wagons and donkey carts. Excavations and building work for the purification works were also carried out by hand. (Ref.7)      
1934 Johannesburg sewerageThe North Western Basin drained northwards to the Delta Works opposite Craighall Park. Delta wa built in 1934/35 using the activated sludge process.  (Ref.11.)      
1935 The Boegoeberg Dam in the Orange River (near Upington) was constructed during the economic depression of the 1930's as a measure to relieve unemployment. 
1935 The Clanwilliam Dam (Olifants River) wall was completed in 1935, approximately 38 m high.
1936 Devastating hailstorm with hailstones the size of coconuts reported at Settlers on 1 February 1936. Ten people killed by hailstones. Several head of cattle also killed. Nine people killed by raging water. 380 mm of rain fell in 15 minutes. (Ref.10).      
1937 History of WISA: The first creative steps were taken at a meeting held at the Cydna Biochemical laboratory in Johannesburg on May 4. 1937, when the following resolutions were passed:

That it is unanimously agreed that an Association shall be, and is hereby formed, the objects of that Association being set forth in pages 13 to 15 of the Articles of Association of the (British) Institute of Sewage Purification.

That this Association shall forthwith take steps to become recognised as the South African Branch of the Institute of Sewage Purification.

That a temporary committee be elected to deal with local by‑laws and necessary correspondence, the committee to consist of: Messrs H Clausen, JA McLachlan, BR Spencer and H Wilson.

Those present at the inaugural meeting were Messrs Alison, H Clausen, JA McLachlan. KA Murray, J Pollock, J Richardson, P O'Reilly, J Sampson, BR Spencer. H de Vaal, P Vosloo, and H Wilson. Membership of the Branch increased at a satisfactory rate and additional Group committees were formed in Durban, Cape Town and Port Elizabeth.  (Ref.6)

   
1938 Johannesburg sewerage: The first use of sewage effluent for power station cooling in the Republic of South Africa was in 1938/1939. at the City's Orlando Power Station, when effluent from Klipspruit Sewage Works was used.   (Ref.11.)      
1939 SOUTHERN CROSS INDUSTRIES (PTY) LTD commenced business as the "SOUTHERN CROSS WINDMILL AND ENGINE CO" during 1939 in then the Union of South Africa. At that time it was effectively controlled by the SOUTHERN CROSS ORGANISATION with headquarters abd factory in Toowoomba, Queensland, Australia.

1939

The pier at the foot of Adderley Street was demolished in 1939.  While almost all other engineering work was postponed for the duration of hostilities, harbour work was of strategic importance, and the reclamation continued throughout the war years.  A Dutch contractor, H.A.M., was engaged to complete the job by dredging the new harbour area and depositing the fill on the landward side of the new quays.  Work proceeded round the clock in order to complete the facilities for accommodating wartime traffic, and the expected boom in international trade in peacetime - and the City Engineer was not part of the process! Suddenly somebody realised the several stormwater outlets that discharged into the bay along the old shoreline had been completely forgotten!  The basements of buildings in Adderley Street were already subject to winter flooding, and now the big Dutch dredgers were adding to the problem.  A further complication was that the cooling water ducts to the new Table Bay Power station were being rendered ineffective, and the vastly experienced engineer on that job, former SAICE President D.P. Howells, was scathing in his criticism and refused to cooperate.  The Dutch smiled smugly and reached for the claim forms.  The Harbour Advisory Engineer, Jack Craig, was red-faced with embarrassment, but not as red in the face as Stanley Lunn, the City Engineer.  Something needed to be done in a hurry! The solution was to depart from the time-honoured City Council process of in-house design and to hand the work to a young consulting engineer who had been making quite a name for himself in the country districts.  The call went out to Ninham Shand. (Ref.3.)

   
1939 Uitenhage water supply: Over time improvements were made at the Springs. Stone wall enclosures were constructed which prevented storm debris entering the pipeline. Gauging and pipes were upgraded. The yield was closely monitored and when boreholes at nearby Sandfontein and Balmoral were installed this declined. Disinfection of the water by chlorine gas was introduced in 1939. (Ref.8)

1950

The Berg River was the first river in South Africa on which a detailed limnological and chemical study was conducted. A.D. Harrison and J.F. Elsworth undertook the study and sampling spanned a period of 3 years, beginning in May 1950. Although initially intending to determine the biological effects and indicators of pollution, the objectives of the study shifted to assessing the biota and conditions of life in an unpolluted South African river. The data obtained from the study provides a firm basis for the historical faunal communities and zonation patterns occurring along the river course. This study was not only the first of its kind in South Africa, but aided in the development of methods and provided fundamental concepts for South African river biology. (Ref 21)

1950's

The construction of sewerage reticulation schemes for Pretoria lagged behind the development of the town. This resulted in the necessity of running an intensive "bucket" service, with horse-drawn wagons rattling through the quiet of the night while the barking of dogs indicated where they were changing buckets. This service could only finally be terminated in the 1950's when in the unsewered areas, it was replaced with a vacuum tank service. (Ref.5)

About 6 km south of Gouda is Voelvlei Dam, an important element in the complex water supply system of the Western Cape.  What was originally a little more than a muddy marsh was converted into a dam in 1952 to augment and control the water delivered by the Berg River to places such as Saldanha and Vredenburg near its mouth on the west coast.  (Ref 13)

1956, anthropologist  AC Myburgh discovered a pre-colonial irrigation site on a farm near Carolina, in Mpumalanga (Tempelhoff, 2008).  There were a number of canals on a fairly level tract of land and a dam of sorts had been built to take water from the Gemsbokspruit.  Consequently, a floodplain was formed and water could siphon through the lands.  Myburgh noted that the canals were obviously made for the purposes of irrigation because there were no direct indications of a settlement in the vicinity of what must have been a patch of agricultural land. (Ref 23)

1981

THE LAINGSBURG FLOOD - 25 JANUARY 1981 Television was still a novelty in South Africa when rain started falling gently over the head waters of the Buffalo River on 25th January 1981. The local farmers were at first grateful for the rain; the desolate semi-desert was parched and dry and even hardy sheep were struggling to survive. But the bluish shale soil of the area doesn’t absorb much water, and most of the rain drained straight into the river. A six meter high wall of water build up and ripped through Laingsburg, carrying away people, houses and the N1 road bridge. The Buffalo River that flows North-South through the town, bursts its banks. The confluence of the Wilgehout, Baviaans and Buffalo Rivers, resulted in large waves near the railway bridge. The streets running parallel to the river acted as swift flowing unobstructed water courses for the flood. This meant that residents could not cross these streets even when the water was less than a meter deep. Trapped by the fast running and swiftly rising water, the only course of action was for people to seek refuge on the rooftops of their houses, until these too were swept away by the flood. 425 mm of rain fell in two days. (24th and 25th of January 1981. The average annual rainfall is 175 mm) 104 people died and 184 houses were destroyed. Only 21 houses were undamaged. High-water marks are today indicated on lamp posts. (Ref 16) Flood4.png (119300 bytes)

Planning for the Berg river dam began in 1989 by the South African Department of Water Affairs and Forestry. The process started with an analysis of future needs and water resources in the region, and was subjected to rigorous public participation process and debate. In 1995/6 a comprehensive "Evaluation of Options" study was undertaken, a process in which more than 1,100 individuals and organisations took part. Extensive environmental and social impact studies were undertaken during 1996 and 1997. The Department of Environmental Affairs and Tourism approved the project in 1999. In April 2002, the Cabinet approved the construction of the dam on condition that the City of Cape Town reduces the demand for water by 20% by 2020. Construction began in July 2004. The dam started storing water in July 2007 and was full a year later thanks to good rainfall. According to the South African government, the decision to build the dam was taken only after an extensive review of the alternative options. It also involved an intensive public consultation process.
