Behind the book
Why The Blueprint of Water
He wrote The Blueprint of Water, and his brother Quin built this site, because water treatment is too often taught as a collection of rules, targets, and procedures rather than as a system that can be understood. His goal is to help water treatment professionals understand not only what they do, but why it works, so they can see water systems as connected wholes, solve problems at their source, and become better stewards of one of the world’s most essential resources.
