Yadkin County wishes to conduct a Water and Wastewater System Asset Inventory and Assessment (AIA) and rate study. GPS surveying will be conducted to develop a GIS database of the Yadkin County water systems, County owned wastewater system, and develop an updated CIP for future improvements to the water system. Initial data collection and mapping task will include:
- Valves and hydrants on raw water mains, yard piping mains valves, valves and hydrants on transmission mains, all distribution main valves and hydrants, and any ground storage water tanks are to be GPS located. County staff will assist selected firm in locating valves not easily located by visual observations. County staff will assist in locating meters with GPS.
- Selected firm will utilize historical pictorial maps of the water and wastewater system and project records to help locate valves and line routes.
- Water lines and wastewater lines will be inserted to connect GPS located points. County staff will identity water line routes by painting routes near valves where water line routes are not obvious.
- All graphical information to be delivered in a GIS database.
- Rate study to analyze existing rate structure and provide recommendations to ensure rate equity and long term viability of the systems.
