Kaka Point Wastewater Treatment Plant - Clutha District, Otago, New Zealand

Kaka Point wastewater treatment plant is located in the Clutha District of Otago, New Zealand, serving a small community of 473 residents. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. As a coastal facility within 10 km of the ocean, it operates under New Zealand's regulatory framework, which requires resource consents for discharges to the environment. The plant's discharge volume of 322.03 cubic meters per day reflects the scale of the small population served. Under New Zealand's National Policy Statement for Freshwater Management, wastewater treatment plants must meet stringent water quality standards to protect receiving environments. Secondary treatment is typical for small communities, though coastal plants may require additional nutrient removal to prevent eutrophication in sensitive marine areas. The treated effluent is discharged into the local coastal waters of the South Pacific Ocean, which support diverse marine life including seabirds, fish, and invertebrates. The Otago region's coastline is known for its ecological significance, with habitats for species such as yellow-eyed penguins and New Zealand sea lions. Proper treatment is essential to maintain water quality and protect these ecosystems.

The plant discharges into the coastal waters of the South Pacific Ocean near the Otago coastline. This area supports a rich marine ecosystem, including important habitats for seabirds and marine mammals. The receiving waters are part of a dynamic coastal environment where nutrient inputs from wastewater must be carefully managed to prevent algal blooms and maintain water quality for recreational and ecological uses.
