Crossing Approval Packet

General Information

1. Water & Sewer Pipeline Crossing Permit issued by the City of Greeley Public Works Department ONLY allows the crossing of a Water & Sewer pipeline. Water & Sewer pipelines include water, sewer, non-potable, and service pipelines.
2. If a proposed installation project will cross a City right-of-way or a City-owned easement unrelated to Water & Sewer pipelines, a separate permit must be obtained from the City of Greeley Public Works Department for that crossing. The owner of the installation or contractor (referred to jointly in these instructions as “Applicant”) is responsible for determining the permits and/or approvals that must be obtained from the City.
3. The City CANNOT issue permits and/or approvals for the crossing of private property or that of another public agency. Applicant is responsible for determining which permits and/or approvals must be obtained from a private property owner or a public agency.
4. If a proposed installation project is an oil and gas pipeline, a design for special review by Engineering Development Review (EDR) must be submitted to the City of Greeley Community Development Department a minimum of two (2) weeks prior to the anticipated start of construction.
5. If a proposed project damages a Water & Sewer pipeline, even if a Water & Sewer Pipeline Crossing Permit has been issued, the owner of the installation is liable for the damage. Should a Water & Sewer pipeline be damaged, the Water & Sewer Department will repair the damage and invoice the Owner of the installation for the cost of the repair (typically, that amount is approximately $7,000). Therefore, it is required that existing Water & Sewer pipelines be potholed prior to construction, following the procedures outlined below.
6. Parking lots, sidewalks, streets, alleys, and other paved services may be constructed in City of Greeley right-of-way easements upon approval of the City of Greeley. It is understood and agreed between the parties hereto that in the event it become necessary to repair, maintain, or install pipelines the city shall NOT replace any street, alley, parking area, turf or utility lines and the city shall NOT be liable for damages to the property.
7. If you are utilizing boring, after the procedure is complete, submit your boring log to the City of Greeley. It shall show from one easement edge to the other and include the location of the easement and the existing water line.

Application Procedures

1. Applicant submits a location map showing where proposed installation will be crossing a Water & Sewer pipeline to the Public Works Department.

Minimal Requirements

The following requirements are standard and pertain to every utility that intends to cross or parallel the Water & Sewer Pipelines (shall be defined as water, sewer, non-potable, and service pipelines). These minimal standards were developed to meet the State of Colorado Design Criteria for Potable Water Systems per Colorado Department of Public Health & Environment. These are minimal standards that may be adjusted by Water & Sewer upon plan review due to field conditions, soil conditions, service line connections, maintenance/repair of pipelines, burial depth, type of utility crossing, and adjacent manholes.

Perpendicular Crossings Installation

• For bored crossings, there shall be a minimum of 2 feet clear separation above or a minimum of 3 feet clear separation below an existing Water & Sewer pipeline. When reaming, you must allow for the outside diameter of the reamer plus the applicable 2 or 3 feet clear separation
• For open cut crossings, a minimum of 18″ clear separation above or 3 feet clear separation below an existing Water & Sewer pipeline. (NOTE: The exact clearance distance, not the minimum, must be shown on theprofile drawing.)
• The encasement piping shall span a minimum of 10 feet on both sides and be centered on the existing water or sewer main.
• Any crossing that spans an exclusive water or sewer easement shall span the entire easement with the casing.
• All crossings must be at a 90-degree angle to the water or sewer main.
• All crossings shall be contained in an encasement pipe consisting of any of the following:
  • DIP Cl 51
