Conclusions

Take home message

- It is possible to monitor water quality for both safety

and security purposes. However, if technology

installed is only aiming to protect the water utility

from intentional attacks, it will probably be

forgotten. It needs to be integrated on the daily basis

operation of the drinking water network.

- Not necessarily a big investment is needed for

security approach. Existing assets can be used. Level

of protection desired is key.
