Document Summary

Water usage is a huge significance in the lodging industry. In recent years, water and sewer costs have risen at a rate much greater than inflation.

In most cases pumps will bring water to user.

Water sources: local utility, well, stream, lake, desalinization, tanker. System components: pipes, valves, pumps, filters, softeners, water heaters, storage tanks, fixtures. Pumps, wells & water pressure: concept of water pressure 1 psi, a column of water 2. 3 ft high will exert 1lb. of pressure on 1 square inch.

Water quality concerns: potability, color, odor, taste, clearness, mineral content, acidity/alkalinity.
