Community-Led Initiatives and SDG6: Clean Water and Sanitation

Community-led initiatives often approach water management in holistic perspective, with water provision (for domestic, agricultural and other uses) and sanitation being integrated into wider water management systems at community and landscape scale. [1] Research in the UK and Ireland shows high levels of public support for greater inclusivity and community empowerment in relation to planning and decision-making in water management; community-level control over water provision and sanitation infrastructures as well as wider catchment management can make important contributions to this.[2] A survey of 29 showcase ecovillages by Global Ecovillage Network, found that all but one were actively working to conserve, restore and/or replenish stores of freshwater. The most common techniques were efficient irrigation systems combined with mulching to reduce water evaporation from soil (73% of reported cases), behavioural measures such as mindful showering to avoid unecessary water use in domestic contexts (70%), capture and storage of rainwater (67%) and recycling of greywater (63%).[3]

In Tamera Ecovillage in the Alentejo region of Portugal, water management is a central ecological topic. The community develops and tests a wide variety of infrastructures for water retention in the landscape and usage within the community, and promotes wider discussion, reflection and innovation through yearly and various forms of collaboration with internationally recognised authorities as well as testing a wide variety of infrastructures to support and enhance the short water cycles and its storage.[4][5]

Other general approaches include:

  • Direct collection of rainwater combined with effective systems its storage of water, reallocation among households, biological and physical retention and treatment and reuse of rainwater.[6][7]
  • Reuse of treated wastewater (black and grey water) for agricultal and domestic purposes, often combined with use of composting toilets and other sanitation methods that reduce water inputs, allow hygenic onsite processing of waste and allow organic matter to be retained within and/or returned to local ecosystems, and provide new potential for installation of effective sanitation systems in sites remote from central infrastructure.[8][9][10][11] as well as more rural and less "infrastructured" places [12]
  • Nature-based sewage treatment facilities such as Biomatrix, developed at Findhorn Ecovillage in Scotland.
