For this Haines Borough water supply project, proHNS staff designed a new impermeable roof membrane system to replace the failing timber and shingle roof. A major component of our work was review and acceptance of the membrane’s installation specifications. Our staff worked extensively with the Alaska Department of Environmental Conservation (DEC) to navigate the permitting hurdles of constructing a new non-standard roof system for an aging water tower while adhering to NSF/ANSI 61 drinking water requirements. This project was successfully constructed in the summer of 2016 without a need for change order or revision.
