Wastewater Upgrade
The construction areas contain a proportion of clay which retains moisture for long periods and has an impact on the accessibility and safety of the work site. This required necessary adjustments to the contractor’s program of activities.
The bulk of the new storage lagoon embankments are constructed from compacted earth with an additional finishing layer of quarry material that forms the base for the final poly liner. Due to an unexpected high rainfall event, some of the finishing layer was damaged which delayed the fitting of the poly liner.
A simple regrading of the embankments to original construction finish was all that was required to rectify the situation.
Where practicable, the contractor has continued to undertake works at the site including fitting out of the pump station with equipment. Larger civil/bulk earth works have been kept to a minimum until the dryer periods forecast for spring.
Council estimates that the Hampden Road pump station and adjacent storage lagoons will be completed, commissioned, and placed into service in October/November 2023, subject to spring weather conditions.
