When properly designed and sized, WSPs deliver high quality effluent at marginal running costs. Their minimal maintenance requirements make them relatively hard to break – the textbook example of “appropriate technology”.
The simplicity and elegance of natural treatments systems will always have a special place in the hearts of many sanitation engineers but their large footprint has made them increasingly difficult to site in rapidly growing cities. Furthermore, trends toward resource recovery are changing the calculus for “appropriate technology”; these days, maximizing net financial recovery may trump achieving the bare minimum operating cost.
This article is a synthesis of years of experience operating mechanical dewatering equipment and vetting tens of technologies. The article includes comparative costs as well as design and operational considerations.
