Mr. Todd Blomstrom Trunk Watermain Condition Assessment August 18, 2020 Page 2 geotechnical field work, and review the resulting geotechnical report. Soil testing will be conducted to assist in evaluating the potential corrosive nature of soils along the pipe alignment. A map generally categorizing soil corrosion risk as low, moderate or high will be prepared based on measurements of moisture, particle size, acidity, and electrical conductivity. TKDA will prepare an initial high-level evaluation for implementation of anodes or cathodic protection that could be considered to manage pipe corrosion. f) Review of critical infrastructure: TKDA will review the existing utilities and infrastructure in proximity to the existing watermain that would be affected by a watermain failure or that would limit repairs of a watermain failure. g) Interview public works staff: TKDA will interview Public Works staff to document their institutional knowledge of the existing trunk watermain. h) Prepare Summary Memo and Recommendations: TKDA will summarize all of the findings of the desktop study in a technical memorandum. This document will prioritize where the watermain is at most risk of failure and where a field investigation should occur to further understand the condition of the existing watermain and repairs or replacement that may be needed.
