When capacity looks like this?

Our process, in VA:

In other words…

We explore the entire water chain…

Catchment SourceTransport &Point of

use

…using local knowledge…

… to find the weak links.

Visualizing the issues…

… people can take informed decisions…

… on practical ways to mantain control…

…including in emergencies

Simple, but rigorous enought

…backed by comprehensive analysis…

Uses whaterver technology is available

In sinergy with supporting programmes

… and realistic documentation and auditing

I can… You can too.

Validaton

It is a Quality Control function

Verification includes validation

From the catchment to

The producers are in charge

Risk management

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

The source(s)

Who is producing the water?

Can she, be the producer?

Collection, transport…

Who is the producer in this part of the chain?

… and point of use

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

Water Vendors

Who is the producer?

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”

The Risk Analysis

The Tools: Checklists

Catchment Source(s) Transport &Point of use

The Checklists

Explains concepts like “depth of geological circulation” or “Depth of Caption”

The Checklists

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

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)
