401.1 
Minimum Size, Looped.
All water mains shall be a minimum of six inches (6") in size and shall be constructed of PVC pipe rated for fire protection service. All water mains shall be looped, except in the case of temporary dead ends where provisions shall be made for future extension.
401.2 
Provision for Future Extensions.
All water lines shall be extended, where necessary, to the borders of the development for future extensions of the distribution system. The City may participate in the cost of oversizing lines required to serve land areas or improvements beyond the development.
401.3 
Fire Hydrants.
Fire hydrants shall be installed as part of the water distribution system. In residential areas, fire hydrants shall be served by a main line of six inches (6") or larger and shall be located at a distance of no greater than five hundred feet (500') on a clear path to each residence. In commercial and industrial areas, main lines shall be eight inches (8') or larger, and fire hydrants shall be located at a distance of no greater than three hundred feet (300') on a clear path to each structure.
401.4 
Valves.
Valves shall be installed at the intersections of all water mains. The minimum number of valves shall be one less than the number of lines at the intersection. In-line valves shall be installed at approximately one-thousand-foot (1000') intervals.
401.5 
Depth of Cover.
The depth of cover of water mains shall be a minimum of forty-two inches (42") below finished grade or if finished grade cannot be determined, 48' below existing grade.
401.6 
Backfill.
Trenches for all lines, including all service laterals, installed across proposed or future paved areas shall be backfilled with soil having a P.I. between 5 and 20 and compacted to 95% Standard Proctor.
401.7 
Air Relief Valves.
Air release valves and/or air vacuum relief valves shall be installed at critical water line high points.

(Ordinance 122110-B adopted 1/18/11)
Service connections shall be installed and marked by stake (water “taps”) for each unit (dwelling or commercial/industrial) in the development intended for individual ownership at the time of construction of new water improvements. If individual utility connections for apartments are desired, service connections shall be installed for each apartment at the time of construction of new water improvements. Such service connections shall be the appropriate size to serve the intended use of the property, as approved by the City, and shall extend from the public water main to the lot property line or utility easement line, as the case may be. All corporation stops, service piping, curb stops, meter boxes and vaults and any other material required for the connection shall be included in the service connection installation.
(Ordinance 122110-B adopted 1/18/11)
If allowed, alternative potable water facilities shall consist of individual lot water wells or a common water well with a distribution system meeting the criteria of a Public Water System to provide service to all lots in a subdivision.
403.1 
Variance Required.
A variance from the requirement to provide water facilities may be granted by the City at the time of preliminary plat approval if it is determined that the municipal water system cannot be feasibly made available to the area of development. The City shall be provided with sufficient technical data (topography, water demand, existing water systems, etc.) and construction cost figures to demonstrate the proposed development’s need for an alternative to City water facilities. A separate water treatment/distribution system or on-site, individual facilities shall not be constructed unless such separate facilities are more beneficial to the City than constructing an adequate system extended from and connected to the existing municipal system.
403.2 
Approval of Water System.
The City shall not approve the final plat until the water system plans and water well(s) are approved by the Texas Commission on Environmental Quality.
403.3 
Construction to City Standards.
All water lines shall be placed in public rights-of-way or easements and designed/constructed to City standards.
403.4 
Dedication of Public Utility Easements.
If the City approves an alternative water facility’s installation, utility easements shall be dedicated for the future installation of municipal water system improvements.
