This meant extensive dewatering, confined space entries, and deep shoring. The gravity feed line was laid on a minimal grade, which extended for 3km through the main road into Waiuku, with a range of existing services to work around. We were restricted by the hours in which we could work due to the residential location, and traffic management restrictions. All material that was removed to allow installation of the pipe had to be replaced with a certified, compacted aggregate.
Despite these challenges, we were able to meet deadlines, watercare standards, grade and invert levels were achieved.
