Uppsala is one of the oldest cities in Sweden. Today it is also one of the fastest-growing cities in the country. Over the next few years, completely new neighbourhoods with approximately 14,000 new homes will be built in southern areas of the city. Weholite ensures safe and reliable transportation of stormwater and waste water - and safety is of utmost importance because the newly installed pipelines will run through a water protection area.

Uppsala with its population of 170,000 is Sweden´s fourth-largest city, and today faces strong pressures to grow and develop. During the next few years, approximately 7,000 new homes will be built in Rosendal, a district located a few kilometres south of the city centre. In addition, plans to build approximately the same number of homes in Ulleraker, close to Rosendal, are being drafted. Since large parts of these districts do not have water supply or sewerage, the municipal water utility Uppsala Vatten och Avfall is building new main pipelines for both stormwater and waste water between the Rosendal, Kungsängen and Ulleraker districts.
