In Unsustainaville, water is purified in two locations

Problems with Water Purification in Unsustainaville

There are several problems with these kinds of water purification:

  • Chlorination is effective, but it is also quite expensive and relies on the availability of chlorine, which is sometimes limited. Additionally, there is a lot of organic pollution that is not addressed with chlorination.
  • Boiling is very expensive for the local population in the low-income areas - so the very poor cannot afford it and frequently suffer from water-related diseases. Boiling with wood also puts a big strain on the forests around the city. Furthermore, it leads to indoor air pollution, causing respiratory diseases.
