Att dimensionera vattentorn / To design water towers
The article discusses how knowledge has been accumulated by water engineers for optimizing the size of water reservoirs in drinking water supply systems. The most important knowledge for proper sizing has always been to know the water demand. How much water is consumed per day in the net-work? Second most important fact is the production capacity. It is important to be able to produce water from a water resource at sufficient amount. Then comes the demand for fast distribution from the reservoir to the net-work. The earliest reservoirs were built to contain at least a day’s water demand, or even more. A technical break-through came when electricity powered pumps could be used instead of steam-powered pumps. This opened for smaller reservoirs. Another technical change came with the reinforced concrete, that facilitated cost-effective larger reservoirs. Experiences from successful and less successful plants and reservoirs have always been very important for improving the
rules of designing.
