Construction Phase
Construction may only begin after the pre-construction meeting is held. Should the start of construction be delayed and extend to more than a month after the pre-construction meeting is held, Southgate may require a subsequent meeting prior to construction starting.
Southgate will designate a representative for construction observation – this representative will be the Point of Contact for construction-related coordination and issues.
The Applicant is responsible for constructing the system facilities per the approved plans. Any deviations from the approved plans require prior written approval from Southgate.
Construction Water
Construction water is available by purchasing a hydrant-use permit.
Service Connections
The property owner is not authorized to use water or discharge sewer until after Southgate has approved your service connection license application. Service connection license applications will be approved after Certificate of Project Acceptance has been issued and payment received; however, Southgate will approve Stub-ins after main line testing is complete and before Project Acceptance. Stub-ins permit the contractor to install the service line from the main to the edge of ROW/easement in order to accommodate paving. No physical connections between the stub and the served premises are permitted until after the system connection charges have been paid and licenses approved by Southgate, Denver Water (water), and the City of Englewood (sewer).
The penalty for an unauthorized service connection is two times the system connection charge (tap fee).
Project Acceptance
For system extension projects and fire hydrant installations, a Certificate of Acceptance will be issued to the Property Owner/Developer after completion of the following requirements:- For water system extension projects: passing hydrostatic, chlorine and clear water tests and applicable test results submitted to Southgate
- For sewer system extension projects: passing low pressure and deflection tests, and video inspection results submitted to Southgate
- Post-construction punchlist items addressed to the satisfaction of Southgate (coordinate your post-construction walk-through with your inspector)
