CHAPTER 8 – WATER MAINS
8.01 Ownership. Denver Water owns all water mains located in the City and County of Denver and owns or has dominion over all water mains located in areas served under Total Service or Total Service Improvement Distributor Contracts. The Distributor owns water mains providing service to premises located in areas served under Read and Bill, Master Meter and Master Meter Maintenance Distributor Contracts. Private systems are the responsibility of the Licensee, and may be subject to regulation by the Colorado Water Quality Control Commission.
8.02 Operation and Maintenance.
8.02.1 Mains Owned by Denver Water. Denver Water operates and maintains all mains and appurtenances it owns. Denver Water will repair any mains damaged by the acts of third parties and will charge the expense of repair to the responsible third party.
8.02.2 Mains Owned by Distributors. All mains owned by Distributors under Rule 8.01 shall be operated and maintained by the Distributors in conformity with Denver Water’s Engineering Standards and these Operating Rules.
8.02.3 Unauthorized Operation. Denver Water may assess civil penalties against any person who operates any valve or fire hydrant or modifies any portion of the Water System without approval from Denver Water.
8.02.4 Variations in Operation. Water pressure and water flow in a main may vary as part of normal operations of the Water System. Denver Water reserves the right at any time, without notice, to modify water pressure or shut off the water in a main as part of its operation, repair, replacement, modification and maintenance of the Water System. Denver Water is not responsible or liable for damage resulting from pressure changes or stoppage of the flow of water through the Water System.
8.03 Construction of Water Mains.
8.03.1 Denver Water May Require Construction. In order to provide adequate water service to property within its service area, Denver Water may in its discretion require construction of new mains or modifications to existing mains. Such required construction may include oversizing of new mains, up to 20 inches in diameter. The applicant for service or the party whose activities create the need for modifications shall pay the full costs of construction, including the costs of any oversizing. Denver Water reserves the right to design and install mains and to install connections to its conduits or mains, at its discretion and at the responsible party’s cost.
a. Enlargement of Mains. If an applicant requests new or increased service which, in the determination of Denver Water, will impose a demand in excess of the capacity of the existing main, Denver Water may require that the existing main be replaced with one of appropriate size, which may be larger than required solely for the applicant’s needs.
b. Extension of Mains. No person may extend, modify, replace or relocate any main without the specific permission of Denver Water. Denver Water will establish procedures for applying for main extensions or modifications.
c. Looping and System Improvements. In order to provide adequate water supply and fire protection service, and to protect water quality and system integrity, Denver Water may require that the water system be replaced, extended or otherwise modified. Except in rare circumstances, Denver Water will require that mains be “looped", i.e., connected to more than one main owned or controlled by Denver Water or a Distributor. Denver Water in its discretion will determine the extent of looping required.
8.03.2 Main Extensions Inside Denver and Total Service and Total Service Improvement Areas.
a. Responsibility for installation. In most circumstances, the applicant will install all mains that are 20 inches in diameter and smaller, and Denver Water will design and install all mains that are larger than 20 inches in diameter. Denver Water reserves the right to install connections to its conduits or mains at its discretion. Regardless of who installs the main, the applicant shall pay all costs for designing, constructing or modifying the water main, including all appurtenances and fire hydrants.
b. Location. Unless Denver Water decides on another arrangement, mains and appurtenances must be attached to a Denver Water owned or controlled main.
c. Deposit for Denver Water Work. If Denver Water determines that it should perform all or any portion of the work, the applicant shall deposit the estimated cost of the work before design begins. The deposit will be applied against actual final cost of installation to be paid by the applicant.
d. Work Performed by Contractor. If Denver Water determines that the main extension is to be performed by a contractor, the applicant shall:
(1) Submit plans and specifications prepared by a registered professional engineer for the proposed installation, which plans and specifications must be approved in writing by Denver Water prior to award of contract and commencement of installation.
(2) Pay all costs of plan review and inspection as determined by Denver Water.
(3) Ensure the work is performed by a contractor pre-qualified by Denver Water.
8.03.3 Main Extensions in Other Distributor Contract Areas.
a. Ownership of Mains. In Read and Bill and Master Meter Distributor Contract areas, the Distributor will own and maintain all water mains installed in its service area that distribute water provided by Denver Water to its customers. In Master Meter Maintenance areas, the Distributor will own the mains, and Denver Water will maintain them, pursuant to the Distributor’s contract.
b. Responsibility for Installation. The Distributor or the individual applicant for service shall pay all costs for extending the water main, including plan review and inspection costs. Denver Water reserves the right in its discretion to install connections to its conduits and mains at the Distributor’s cost.
c. Approval of Main Extensions. The Distributor shall submit plans and specifications prepared by a registered professional engineer for the proposed installation, which plans and specifications must be approved in writing by Denver Water prior to award of contract and commencement of installation.
8.04 Engineering Standards. The criteria and scope of extensions or modifications shall be determined by the Director of Engineering. Specific requirements for minimum design or operating criteria, preparation of plans and specifications, and construction practices are prescribed in the Engineering Standards of Denver Water or will be determined by the Director of Engineering.
