Marla Smith-Nilson is director of Seattle-based Water 1st International and has worked for decades trying to improve access in the developing world to clean water and safe, healthy sanitation.
Smith-Nilson said she welcomes the Bill & Melinda Gates Foundation decision to get more involved in water and sanitation issues. But she is concerned that their primary interest in re-inventing the toilet is focused too much on the simple fix. Here are Smith-Nilson’s thoughts:
——————————————————————————————————————————
Today, 2.5 billion people lack access to both a safe, convenient water supply and a sanitary toilet – a situation that stems from but also drives poverty, illness and inequality.
As someone who has worked for 20 years on water and sanitation needs in the developing world, I welcome the Gates Foundation’s increased interest and investment in addressing these twin problems.
But I am concerned with their emphasis on reinventing the toilet — or with any solution that is based primarily on solving the water and sanitation problems by virtue of a technological advance. I’m an engineer by training and hardly opposed to technological progress.
The fundamental challenge in water and sanitation is not so much a technological hurdle to overcome as it is a systems problem that simply cannot be resolved by trying to fix any one part in isolation.
