Patented in the 19th Century, vacuum sewers are making a comeback. Vacuum is created and maintained at a central collection station and extended, through a network of collecting pipes, up to interface units connecting with standard plumbing. The technology has become competitive enough that engineers are now routinely comparing vacuum sewage collection with other collection options. This article describes in detail one such project in Canada in which the cost of the vacuum system was found to be up to 30% lower than that of the other alternatives.
