WHO & UNICEFToolkit for Monitoring & Evaluating
Household Water Treatmentand Safe Storage
Workshop on HWTS and Water Safety PlansNovember 14‐16, 2013
Nagpur, India
Ryan RoweWater Institute at UNC
Who really needs HWTS?
• Water safety plans – example?
Starting points
• Target those at high risk (cholera)
• People living with HIV (crypto)
• The malnourished
• Children in schools
• Emergency response
• Huge unmet need
• Need knowledge of failures & successes
• Harmonise activities by governments, donors, researchers, practitioners
• Improve quality and comparability of data
Motivation for toolkit
Correct and consistent use / Effective useneeded for health impact
Challenges in achieving full benefit
Chart source:Brown & Clasen, 2012.
• Purpose of HWTS and proven methods
• Designing and conducting M&E activities
• Choosing and using 20 harmonised indicators
• Case studies from the field
• Annexes
– Example surveys and sanitation survey forms
– Links and resources for program design, implementation
– Water quality monitoring field test options
Uses for the toolkit
• On‐site visual inspection of water sources to identify hazards to water safety
• Checklist of questions, provides a measure of risk
• Address visible risks before sampling water quality!
Know the area around your water
So, if a bird is shitting in it …
Uncovered water storage is a risk
Area around water point is
unclean

Or, if water is handled unsafely …
20 recommended indicators
• Research‐tested, common sense, stakeholder reviewed
• Sample survey available in the toolkit
• Mix and match according to your needs and constraints
• Self‐reported data not as reliable– Better to ask: Did you do anything to make the water safer to drink? How?
• Confirm through direct observation – Ask to see the treatment method, stored water; Is the device wet?
• % households with REPORTED andOBSERVED use provides a more reliable indicator of level of uptake

Reported and observed use
• Knowledge is just the first step!– Do they know how to treat? Where do they draw their water? What about vulnerable members of household?
• Then confirm through demonstrated use and alsomonitor regularly
• % households with CORRECT, CONSISTENT suggests knowledge and behaviour change
• Multi‐step products require additional training and support* but may be more microbiologically effective
Correct and consistent use
Lantagne & Clasen, 2012
• Added element of objectivity and measure of risk
• Common parameters– Turbidity, chlorine residual, bacterial indicators (e.g. presence/absence of E.coli or TTC), arsenic, fluoride
• Use field‐proven and performance tested methods!
• % of households with EFFECTIVE use derived from measuring water quality before and after
Assessing water quality

Deciding which indicators to use
Interpreting data, share lessons
What works, what does not?
Share results for feedback and improvement
Correct, consistent and effective use can reasonably be linked to health impact
