Why should I contribute? Network members are encouraged to contribute to achieving the mission of achieving ‘safe drinking-water for all’. By sharing the results of the work you are doing and the lessons you’ve learned, you can help others to improve their programs. Successful program examples are useful, but we also want to hear about your failures too. By showcasing where you went wrong, it provides a valuable service to the entire community.

What can I contribute? Contributions to the newsletter are welcome. Material considered relevant includes recent publications (peer-reviewed or otherwise), presentations, events, resources, calls for papers/proposals, etc. An example of a contribution which is acceptable is a request for assistance in improving your product or approach to implementing HWTS. Or you may be a researcher and would like to share your research question with others or seek input or contacts for your work. You may also refer to a previous issue of the newsletter for additional examples (browse the archives below).

What should my contribution include? Please adhere to the following contribution guidelines when evaluating whether you have something to share. Your contribution should:

  • Include descriptive text, limited to 150 words.
  • Be recent, factual and not self-promoting (no new product announcements or requests for funding).
  • Share insights or knowledge from your work for the benefit of others.
  • Include links to your organization’s own website and any attendant publications.

Note: If you do not have a website and wish to make a publication of your work or project results available online to the public, please email it to us at along with a description adhering to the above guidelines.

When will my contribution be published? We will work to include your contribution in the next issue of the newsletter, which is produced every six to eight weeks. However, please note this is an invitation to contribute not a promise of publication. The Network Secretariat (WHO, UNICEF and the Water Institute at UNC) may choose not to publish your contribute or may delay it for a future issue of the newsletter.
