20 Gallon Challenge publishes practical guidance for people who want to reduce water use without making daily life impractical. Our coverage turns water conservation into specific actions readers can understand, measure and maintain at home, at work and in their communities.
Accuracy and useful context
We aim to answer a clear question and explain what a reader can do, why it may help and which conditions could change the result. Coverage includes indoor water savings, leaks and measurement, irrigation, landscaping, drought and water supply, conservation programs, school and community projects, and business water efficiency.
Facts, calculations and recommendations should be relevant to the decision at hand. Water-saving estimates state important assumptions, units and time periods so readers can check the arithmetic or substitute their own measurements. An estimate is not presented as a guaranteed result.
Research and source selection
Research may draw on EPA WaterSense, local water agencies, state water resources, utility conservation programs, extension services, current drought and water-supply sources, manufacturer documentation, and building or fixture specifications. We prefer direct and current sources for rules, rebates, restrictions, product specifications and other details that can change.
Sources are selected for their relevance to the specific claim. Official program information is used for current requirements, while technical documents and specifications help explain fixture performance or measurement methods. Attribution should make clear where important facts, figures and reported findings originated.
Evidence, estimates and opinion
We separate sourced facts from editorial judgment. Opinions and practical recommendations are presented as judgments, with the reasoning and tradeoffs explained. Generated examples or hypothetical scenarios are identified as illustrations rather than observed results. Firsthand testing, measurements or experience are described only when documented for the article, and only within the scope of that evidence.
Readers can see this measurement-focused approach in guides such as the DIY shower-flow test and the overnight water-meter leak test. These methods help readers verify conditions instead of relying only on broad savings claims.
Corrections and updates
Material factual errors should be corrected when identified. Time-sensitive details may also be updated when rules, rebates, restrictions, specifications or water-supply conditions change. If you notice an error or have relevant supporting information, use the contact page or email contact@20gallonchallenge.com. Please identify the page and passage in question and include a reliable source when possible.
