Maybe it is a idea to get our own bottled water with the water4water logo on it that explains the project and people can buy it.
There must be companies that sell bottled water and allow your own logo on it.

Hi Arie, thanx for suggestions; already some students went to A&H supermarket and asked to donate x amount of bottles.
Maybe some students can desing a logo based upon the one on the home page? And upload a A4 landscape pdf with 2x label to put around a bottle.
Open for more ideas & options, let's think outside the box

I have found some site you maybe want to take a look at concerning the printing of the labels of the bottles:

Ofcourse I'm not the one to make decisions about these thing, just bringing uo some ideas.

Hi Edwin,
thx for tips on sites :-) Actually, the W4W project is set-up to decide together as a group.
I’ll be visiting the Elde College on December 5th around noon, you can recognize me by my white beard, red coat and white horse outside … sorry just joking.
I’ll be waiting fro you in the teachers lounge, and mr Wels promised to get you’ll together so we can discuss about W4W.
Cu on Friday, greetz, Bob.

Here is another website where you can purchase bottles of water. This company also makes bottles of water for charities, 'goedendoelenwater' in Dutch.
