Getting water to the home is one thing, making sure that it is safe to drink and to use for cooking, washing and domestic purposes is quite another. The advantage of groundwater sources is that the water often needs little or no treatment to be safe - however, it can get contaminated. The two main intervention treatment options are:
- Household Water Treatment
- Centralised Water Treatment for piped systems.
Water treatment should not been looked at on its own - because it adds costs, complexity and another thing to go wrong, it is often best avoided. Therefore, the starting point should be Water Safety Planning:
- Water safety plan: A field guide to improving drinking-water safety in small communities
- Water Safety Planning for Small CommunitiesStep-by-step risk management guidance for drinking-water supplies in small communities
Household water treatment is closely associated with the RWSN theme 'Accelerating Self Supply', however, it has its own network because this topic is so complex:
- HWTS KnowledgeBase: access information about HWTS technologies, projects, research, FAQs. Video on how to navigate it.
- HWTS e-learning modules: a platform with micro-learning tools related to the multi-barrier approach and HWTS. Video on how to navigate it.
- Knowledge Point: KnowledgePoint is a global Q&A forum for people who work in the humanitarian and development sector. It includes a broader set of topics, including water supply and water treatment, amongst others:
- HWTS and Water Safety Plans technical brief
- Training resources on HWTS
Other good resources include:
