 - Are there other reasons for fresh water shortages? - The facts and figures surrounding the usage of fresh water for Irrigation. || -Research: Use the Internet, Library, Palmerston North City council, and Encarta to help us answer our questions about Fresh water usage. - Speak to people who are high users of Fresh water; For example: Farmers, Factories (Fonterra!) || **Mixed** **together**, at a treatment plant in Palmerston North, and pumped into the Manawatu River. The Grey water is ‘surplus’ and could be put to use instead of pumped into the river. || - How could Grey water be separated from ‘waste’ water? - What is waste water treated with when it goes through the treatment plant? - Are the treatments that are used on the Grey water safe for the Environment? || - Talk to a representative from the Palmerston North Waste Treatment Plant and possibly the Palmerston North City Council. - Research other Waste treatment plants from around New Zealand, and internationally, to determine the different ways that Grey water may be treated. || - How the rate of Growth, using Grey water, compares to the rate of Growth using Fresh water, also how these compare to the rate of growth with mixed ratios of Grey and Fresh water mixed together. || - Conduct a survey with Farm owners or managers about their feelings on the use of Grey water – For example, if it is viable, would they use it? - Conduct research into the rate of growth required (for crops and grass) by farmers. (E.g. How many weeks to meet requirements etc.) || First ‘Need to know chart’ – September 3rd, 2009
