KC Water maintains and operates water collection, treatment, and distribution systems; wastewater collection and treatment systems; and stormwater management systems for 170,000 residential and business customers in Kansas City and for 32 wholesale customers in the Kansas City region. The operation is funded by fees charged to customers based on their use or impacts on the water, wastewater, and stormwater utility systems.
KC Water needs science and engineering assured capabilities and workflows that can be fully build-out and relate our systems to the real world. Historic data can be inaccurate, or altered by other work. A significant percentage of our data is no longer available to staff. Original drawings were redrawn into scaled map quadrants and the regional data, and even some of the redrawing have been lost and heavily altered by redevelopment. A significant percentage of data simply no longer exists, or was never drawn (was not possible or practice in those days). Some re-drawings show a pipe connecting to an inlet built in 1907, but nothing on size of pipe or inlet. The result is many sources, all with variations in completeness and accuracy, resulting in a compilation of GIS that has had many rounds of editing, but all relative to the regional conversion using the regional data and its limitations.
Without accurate asset information, everything else is compromised particularly in this modern age of analysis that so critically depends on having this accurate information for other critical needs such as: modeling, asset management, condition assessment, life-cycle cost and planning for assets and for improvements or sharing of critically needed underground and surface information for redevelopment and critical improvements needed within our city.
KC Water seeks a solution that allow the department to;
- Accurately identify the location, type, dimensions, connectivity and the accurate absolute x, y, z to known datum with absolute accuracy of 2 CM vertical and horizontal, or better of the selected or discovered assets in the field.
- Determine and develop methods of accurate asset and condition assessment through use of above ground and/or below ground Drone technologies.
- Develop and compare these approaches to methods of scanning and digitizing paper and microfilm data.
- Compare methods for a small area or set of plans for a portion of system as the project deliverable.
- Create a comparison of scanned and digitized data vs. field collected data for the select area to show the differences, benefits and issues/needs of each method.
- Drone and Survey work with 2 CM absolute vertical and 2 CM absolute Horizontal accuracy.
- Have a comparative estimate of accuracy/quality vs. the time needed to develop and deliver per unit area or length.
