Building SY038 in the South Yard of the HMNZ Naval Base is the wastewater treatment plant for the Drydock (Calliope Dock) operations. The influent to the plant is generated by hull cleaning operations on the vessels and can include a number of substances.
The purpose of the plant is to treat the influent so that it is suitable to discharge into the council sewer.

The existing plant includes a 250 cu.m influent storage tank and a 20 cu.m equalisation tank and both of these tanks require replacement due to their deteriorating condition.

The proposed works include the construction of a new raised concrete slab adjacent to the existing plant and the erection of two new stainless steel ‘settlement’ tanks (at approx. 40 cu.m capacity each) and two new timber stave influent storage tanks (at approx. 130 cu.m capacity each). Also included in the works is the required pipework, valving and instrumentation to integrate these new tanks into the existing plant. Other items of work include roadmarking and signage for the adjacent carpark, walkways and security fencing.
