The first phases of Sky Ranch were within the gravity-fed portion of the collections system at Sky Ranch. As the community expands over a topographic ridge a lift station is required to deliver sewage from the southeast phases of the development to the existing Sky Ranch Water Reclamation Facility. The Facilities can be accessed during construction and occasional maintenance by first entering through the vehicle tracking control pad in use for the larger Sky Ranch development which is located east off of Monaghan Road by the construction trailers. Access the Lift station site by traveling south thereafter past E 6th avenue by existing construction roads on Monaghan Road.
