Drainage and sewerage
The Council's Drainage Division is responsible for two essential services, wastewater (including sewage) and stormwater.
The Drainage Division maintains over 300km of sewerage pipes and 400km of stormwater pipes, treatment plants in Bluff, Omaui and Clifton, and also ensures Invercargill and Bluff's drinking water and water supplies meet health and safety standards.
See links at left for more information on blocked drains, culverts, facts and figures, history, septic tanks, trade waste, and water treatment. The treatment section has information on the Clifton wastewater treatment plan (including a four-part video overview), the biosolid project (including a slideshow), the Bluff plant and Omaui treatment.
