Q. Limitations of the five year period of analysis?
A number of restrictions to the analysis potentially arise
- The approach doesn't take account of future benefits/costs after five years either continuing or new
- No information on contract length from the Water Authorities which may be longer than five years
- Other cheaper resources perhaps available over a longer period e.g. it may be cheaper to buy machines rather than rent them
- Analysis doesn't take account of the potential for physical site capacity increases that may turn into available after five years.
