Who is in charge?
Failure of identifying the right actors, with the right capacity will result in the failure of the entire system

What is the capacity of the village?

The Catchment
… and who has the capacityof managing the risks in the village?
For the village, the catchment is the village

Who has the capacity to manage the risks in the home?

Risk management in the WSP
Having a producer without the appropriate capacity ( or an overambitious plan) will reflect in sustained failures in the opertion plans, “permanent emergency “ management, always hoping for intervention “from the next level”

Documentation, Verification and Auditing of WSP
Documents to be included into the “Livre d’Or”
names of the producers, of each water point
WSP checklists, for each water point and the catchment
WSP operation plan, for each water point and for the catchment
WSP emergency plan
any chemical or bacteriological analysis results, collection point, date, name
record of major concerns/complains from the users, and action taken
![Page 43: Water Safety Plans for Healthy Villages](https://reader033.vdocuments.mx/reader033/viewer/2022051816/546fee4faf79596d138b466d/html5/thumbnails/43.jpg)
Documentation, Verification and Auditing of WSP
Auditing will include
the revision of all WSP the documentation,
Application of the sanitary checklists (or operation plans)
Water quality analysis
When either sanitary surveys, or KAP surveys result unsatisfactory, or in the case of outbreaks of
water borne deseases in the village,
water quality analysis should be carried out. Samples should be collected at the source, as well
as at the PoU in selected households. Those analyses will foucus on the bacteriological quality
(i.e. E-coli)
