The great defect of Bulawayo is the smallness of the water supply and the badness of it. At present the inhabitants depend on wells, and water is easily obtainable at 30 and 40 feet, but the water is of a hard and indifferent quality. Up on the Maatschesmuslopje stream, about two and a half miles from the town, there have been constructed three dams of different lengths and varying heights. Number 1 dam is the nearest to Bulawayo, and has a solid stone and cement core starting from the bedrock 10 feet wide, and decreasing by set-backs of 6 inches to a width of 2 feet at the top. Number 2 dam has a puddled core of clay faced with stone, and Number 3 is of similar construction. In April last these dams were full and overflowing, but unfortunately, through bad construction and want of care, there were several leaks, and it is now decided to demolish two of the dams and rebuild them. Numbers 2 and 3 are quite fit to retain the water catchment, and Number 1 will be finished by the end of the year. The estimated storage of water by the three dams is calculated to be between 40 and 45 million gallons. A fourth dam, about to be erected, will, it is thought, considerably increase the storage.
Several critics are of the opinion that the dams will not retain any water, though they were full last April.
We have had four copious showers of rain since our arrival on the 4th inst, but a few hours later the spruits, gullies, and watercourses were almost waterless, the streets showing scarcely a trace of the rain, so porous and thirsty is the soil. Daily it becomes apparent to me that the inhabitants of Bulawayo should lose no time in studying the art of water conservation. In a country just within the tropics an abundant supply of water is essential, and thirty gallons per head per day would not be excessive. Ten thousand inhabitants should be able to command 300,000 gallons daily, but Bulawayo within twenty years will have probably 20,000, and there is no river between here and Khama’s country that could supply 600,000 gallons daily. Numbers of little watersheds may be drained into reservoirs, but if I were a citizen of Bulawayo my anxiety would be mainly on the subject of water. The water question is not at all an insoluble one, because, for the matter of that, Bulawayo will have always the Zambesi tributaries to fall back upon, especially the Guay River.
