Standards for Charlotte Water Private Water Design and Construction
The purpose of this document is to set forth the scope of responsibility delegated by the North Carolina Department of Environment and Natural Resources (NCDENR) to and accepted by Charlotte Water for permitting the construction and/or Extension of Private Water Mains serving two or more structures.
1.02 Definitions (See Schematics 1 and 2 for visual clarity as noted)
Extension – Proposed Private Water Main 40-feet or more in length that connects onto an existing Charlotte Water or Private Water Main, providing service to two or more structures.
Fire System – Private water piping connected to a Charlotte Water, Water Main and dedicated for the fire protection of a project or parcel(s) of land. A Fire System can consist of facilities such as, but not limited to:
Private fire hydrants
Fire Department Connections
Fire booster pumps. (See Schematics 1 and 2)
Private – Describes infrastructure owned and operated by private entities and public entities other than Charlotte Water, such as home owners associations, the Charlotte Housing Authority, owners of multi-structure developments (e.g. apartment complexes, business parks, trailer parks, etc.), property management companies, or other water providers such as Aqua Carolina or Utilities, Incorporated.
Charlotte Water – Describes infrastructure owned and operated by Charlotte Water.
Water Service Piping – Water pipe from the Water Service Connection onto the CHARLOTTE WATER or Private
Water Main to a point 5-foot outside of the structure. (See Schematics 1 and 2)
Water Supply System – The Water Service Piping, Water Distribution Pipes, and all the necessary connecting pipes, fittings, control valves and all appurtenances in or adjacent to the structure or premises. (See Schematics 1 and 2)
Water Main – A water supply pipe or system of pipes 2-inches in diameter or larger, installed and maintained by an entity responsible for water distribution. A Water Main can be owned and operated by Charlotte Water or by other Public or Private entities. (See Schematics 1 and 2)
Water Distribution Pipe – A pipe within the structure or on the premises that conveys water from the Water Service Piping or from the meter when the meter is at the structure, to the points of utilization. (See Schematics 1 and 2)
Water Service Connection – Point at which the Water Service Piping connects to a Charlotte Water or Private Water Main, providing service to a single structure. (See Schematics 1 and 2)
1.03 Delegation of Authority
As of August 1, 2010 NCDENR delegated the authority and duty for permitting Extensions of Private Water Mains to Charlotte Water. Therefore any 2-inch or larger Private Water Main providing water service to more than one structure will require a permit through Charlotte Water. NCDENR is no longer issuing permits for these types of Water Mains if connected to Charlotte Water owned and maintained Water Mains.
Note that any Water Service Connection or Water Service Piping, regardless of size that provides service to a single structure and is not intended for further Extension or additional Water Service Connections, by definition is not considered an Extension and therefore does not require a permit through this process. However, the applicant is responsible for ensuring the project conforms to all appropriate local permitting authorities and requirements.
NCDENR will continue issuing permits for Water Main Extensions providing service to projects such as subdivisions or business parks receiving their water supply from a source other than Charlotte Water. Such sources include, but are not limited to well or surface water sources or another utility provider, including Utilities, Incorporated or Aqua Carolina. In addition, typical large diameter Water Main Extensions, treatment facilities and major public distribution system modifications, such as booster stations and storage tanks will require permits through NCDENR.
Section 2 Permitting Guidelines
The construction of Private Water Mains servicing more than one structure are hereby designated as an Extension and shall require a permit in accordance with applicable law, including these Standards, NCDENR rules and regulations.
2.02 Project Classifications that Require Permitting
A Charlotte Water Private Water Permit is Required for projects such as, but not limited to:
The Extension or replacement of Private Water Mains which provides water service to multiple structures.
Major Modifications to an existing Private Water Mains as determined by the Charlotte Water Engineer or his designee. Such modifications include but are not limited to change in pipe material, location and size of large portions of the Private Water Main.
2.03 Project Classifications that Do Not Require Permitting
Charlotte Water Private Water Permit is Not Required for projects such as, but not limited to:
System Maintenance, whether routine or emergency, of existing Private Water Mains.
Such modifications include but are not limited to:
Repairs to mains in their existing location
Replacement of small portions of the Private Water Main in the same trench with same pipe size and comparable material
Any Water Service Connection or Water Service Piping, regardless of size, providing service to a single structure.
Section 3 Plan Approval
3.01 Approvals Necessary before Contracting or Constructing
No construction shall be undertaken, and no contract for construction, alteration, or installation shall be entered into unless Charlotte Water issues the authorization to construct letter. This authorization shall be issued following completion and submittal of the Water System Management Plan, where applicable, and Engineer’s Report as referenced in the NCDENR 15A NCAC 18C (NCDENR Rules) and approval of the engineering plans and specifications by Charlotte Water. Authorization to construct from Charlotte Water shall be valid for twenty-four months from the date of the letter. Authorization to construct may only be extended if the NCDENR Rules and site conditions have not changed. The authorization to construct and approval letter for engineering plans and specifications from Charlotte Water shall be posted at the primary entrance of the job site before construction begins.
3.02 Changes in Engineering Plans or Specifications after Approval (Revisions)
Deviations from the approved engineering plans and specifications or changes in site conditions affecting capacity, hydraulic conditions, operating units, the functioning of water treatment processes, the quality of water to be delivered, or any provisos stipulated in Charlotte Water’s original and subsequent letters of approval must be approved by Charlotte Water before any construction or installation. Revised engineering plans and specifications shall be submitted in time to permit the review and approval of such plans or specifications before any construction work affected by such deviations is begun. Injunctive relief under G.S. 130A-18, assessment of an administrative penalty under G.S. 130A-22(b), or revocation or suspension of engineering plan approval under G.S. 130A-23 may be sought for any violation of this provision.
