EXERCISE C: The water of your community
This is the last exercise aimed at mapping out the water system of your island. It consists of five simple questions – although the answers are not so simple. It is best done sitting down with the water manager of the island. You will want to know: (1) What are the water sources, (2) How is the (raw) water treated, (3) How is water distributed, (4) Is wastewater treated, is it just a problem or is it a resource, and (5) How is the water system managed?
Having answers to these questions and the ones from exercises 1 and 2, you will have created a kind of dashboard showing the overall water condition of your society and whether the system is at risk of running dry.
1 WATER SOURCES
Which are the main sources of water for the water scheme on your island?
2 WATER TREATMENT
Most probably, you have a desalination plant on the island.
The plant is in good average bad condition
What is the geographical location of the plant and why was it installed there?
How is the desalinated water used (percentage):
How much electricity does the plant use to operate and how is it produced?
What is the yearly cost of the desalination process, total and per m3?
3 WATER DISTRIBUTION
You might either get a map of the distribution system including storage (reservoirs), pumps, pipes and meters, or you will have to make one yourself.
The pipes are in good average bad condition
How extensive are the leakages?
Is there a common sewage network?
How is wastewater treated?
Is wastewater reused for any purpose?
5 WATER MANAGEMENT
Is water management local or in cooperation with other islands/the mainland?
How is it organized?
Which regulations are there on community, municipal and regional level regarding water use, water investments, wastewater, rainwater use, agricultural and tourism use?
What is the cost of water (household/business) and how is the price calculated?
Are there/have there been any water saving activities?
What future plans are there regarding water issues?
