ABSTRACT
In this chapter, the authors detail the complexity of existing infrastructures in mind and, at the same time they can construct infrastructures using more efficient technologies and new systems. In 1990s, Stockholm City Council started planning a new residential neighbourhood, Hammarby Sjostad, aimed at promoting environmental sustainability. Integrating all environmental aspects into urban planning will reveal many dilemmas and conflicts which will require an upstream conflict resolution process with broad participation. The sewage water from Hammarby Sjostad is purified at a large treatment plant just outside the area. The main source of heating in Hammarby Sjostad is district heating—in 2002, 34% of the heat for this system came from the purified wastewater, 47% from combustible household waste and 16% from biofuels. Hammarby Sjostad has excellent access to public transport, including a new electrical tram link.
