This is great. I remember having to endure a few days without running water in my apartment thanks to burst pipes and wondering how I would cope - then I realised how lucky I was to be having it return eventually. I've had a few conversations with Mexican colleagues who told me how it is common to find people getting sick in some poor coastal towns because they don't know how to build latrines properly. It's such a big issue. I hope you find every success with this.
