Centralised treatments using physical disinfection methods are found on the household use level too, but are technologies that can be applied on a larger scale. When moving any technology up to a larger scale, community maintenance and responsibilities as well as ease of access to supplies becomes greater; while costs reduce. However if these aspects cannot be fulfilled, communities may break up water access towards the household level use, so as to divide responsibilities and allow private use to maintain the smaller systems. However, shared knowledge and resources then become more important (community cooperation).
