The Jollyville water transmission main is ncessary to transport water from WTP4 to the Jollyville reservoir, where it will be distributed to Austin businesses and residents.
The Jollyville team has been studying the area since early 2009 as part of the Preliminary Engineering Phase. Several tunnel routes were evaluated with regards to:
- community impacts such as proximity to neighborhoods, schools, and historic sites; safety including traffic patterns, transportation modes and road infrastructure.
- protecting the Balcones Canyonlands Preserve (BCP), Jollyville Plateau Salamander, Black Capped Vireo, Golden-cheeked Warbler, Karst Invertebrates , groundwater, springs, and Bull Creek.
- cost to ratepayers.
- and constructability.
The recommendation is to tunnel the entire length, 50 to 200 feet underground, which adds additional costs to the project but is less disruptive to neighborhoods and the environment overall. This recommendation also includes the most direct route, which is most cost effective for ratepayers.
Technical Background on Jollyville Transmission Route:
Austin Water Utility is owned and operated by the City of Austin, Texas.
