These are some of the questions that have been asked by those who have taken an interest in the future of Christchurch's wastewater disposal since the Council began examining the issue in 1996.
Wastewater is a combination of household wastes from the kitchen, toilet, shower and laundry.
It also includes some industrial wastes. These include wastes from manufacturing, food processing, catering, agriculture, hotels and other large institutions. Some stormwater also seeps into the wastewater reticulation system. Wastewater from industry is generally similar to household waste in that it contains a mix of organic and inorganic materials. However, the proportion of each will differ depending on the source of the industrial wastewater, for example some industries produce a higher proportion of organic and some a higher proportion of inorganic material in their wastewater.
