Utah Admin. Code 309-545-7
The location of the tank and the design of the water system shall be such that the minimum working pressure in the distribution system shall meet the minimum pressures as required in R309-105-9.
Tanks shall be located at an elevation where present and anticipated connections can be adequately served. System connections shall be placed at elevations such that minimum pressures, as required in R309-105-9, will be continuously maintained.
Sewers, and similar sources of possible contamination shall be kept at least 50 horizontal feet from the tank.
The area surrounding a ground-level or buried drinking water storage tank shall be graded in a manner that will prevent surface water from standing within 50 horizontal feet of the tank.
Drinking water storage tanks shall be designed and located so that they can be isolated from the distribution system. Storage tanks shall be capable of being drained for cleaning or maintenance. Where possible, tanks shall be designed with the ability to be isolated without loss of pressure or service in the distribution system.
Potential geologic hazards shall be taken into account in selecting a tank location. Earthquake and landslide risks shall be evaluated.
The site location and design of a drinking water storage tank shall take into consideration security issues and potential for vandalism.
