Field testing setup.

Focus for testing will be functionality, operation and maintenance, ease of training local community to manage the facility. From time to time the flow rate will be checked and samples collected. It will also be assessed how the unit performs over a little longer period.

Initially, the unit appear very attractive for emergency relief situations with flooding etc. After a 6- to 12 months period, a field not will be prepared giving operational experiences gained from running the plant.

MRRD/ NORPLAN and NCA will be following up the plant performance and functionality. The RuWatSIP water testing lab will provide water testing support.


This is the drinking water people collect and use

It has been cecilie and Yasir who has been running the tests at MRRD for the first treatment unit so conficence in the technology is high. But how will it work when placed in a village for community manangement? The test should give some good answers.
Cecilie is a horse owner in Norway and could not leave without testing an Afghan riding horse!

NCA provided a tent for the operators / security men Operator serving a user coming from a nearby house.

Water quality looks great!

- only one thing- the water in the outlet tank being served is quite hot being stored in the hot sunshine. A shade to cool the water is needed, otherwise great!.
