Water quality is central to the challenge of ensuring safe water for all. Here we present the third entry in a three-part blog series on low-cost, low-tech water quality testing. In previous posts, we discussed options for measuring physical and chemical aspects of water quality. In this final post, we explore low-cost, low-tech options for microbial testing.

Money from waste? Revamp your view on sanitation

As an undergraduate student in Kampala, my head was full of thoughts about how I was going to make a living after my studies. Back then Rich Dad Poor Dad was still a best-seller, and I thought to myself: I can become a billionaire if I sell a billion of something to a billion people. Needless to say, it would have to be something that anyone can afford, like toothpaste or chewing gum.
 
So, I wondered, what does every human need? It dawned on me: everyone needs water, food, and energy, every day. The next question was how I could make valuable goods from all the three as a civil engineer.

 

The shape of water for development

From July 9-18, more than 2,000 representatives from governments, businesses, civil society organizations and UN agencies gather for the High-level Political Forum on Sustainable Development. 


Water touches nearly every aspect of development. It flows through and connects the 17 Sustainable Development Goals (SDGs) by driving economic growth, supporting healthy ecosystems, cultivating food and energy production, and ensuring access to sanitation. We cannot achieve the SDGs without our collective action on water.

Avoiding pitfalls between policy and pipes

and analysis.

What motivates poor policy and investment decisions? Why do supposedly good policies not translate into practice? And how can we avoid perpetuating pitfalls between policy and pipes?
 

Our new paper ‘Aligning Institutions and Incentives for Sustainable Water Supply and Sanitation Services’, produced with the support of the Global Water Security and Sanitation Partnership (GWSP), examines precisely these issues. Through research, analysis, and case studies, the report posits that genuine, sustainable progress in water supply and sanitation service delivery is complex, iterative, and multi-faceted. Whether it’s expanding access, improving efficiency, or providing better services – all reforms require their own unique blend of policies, institutions and regulations and all take place in the context of their own unique enabling environment.

What does it take to achieve universal and equitable access to water and sanitation in Guatemala?

Water and sanitation data figures in Guatemala show a challenging reality. Nationally, 91 percent of the population has access to improved drinking water, an increase of 14 percent points since the establishment of the MDGs.
 
Despite the improvement in coverage in relative terms, in absolute terms there are still a significant number of Guatemalan households using water from precarious or unimproved sources such as unprotected wells, rivers, or lakes. In addition, water quality is a concern -- from the monitoring of 20% of the water systems in the country, 54% reported to be at high and imminent risk for human health.
