Costs, utility rates, permits, inspections, environmental duties, health requirements, safety rules and equipment standards vary by country, province or state, municipality, building use, equipment type and project scope. Qualified local professionals and the authority having jurisdiction must determine what applies. Water appearance, taste or a single test result cannot establish safety. Treatment must be selected from appropriate testing, intended use, local health requirements and qualified professional review. This site does not diagnose contamination or certify water as safe.
