Consider a small city with a river as a major alternate source of water supply. People on the edge of the city are not being served by a central water system. See the background data for the city in Table 6. 10. The rainfall data for this city are given in Table 6. 11. A. Determine whether the installation of a rainwater collection system in this city is feasible.

B. Prepare a list of support services needed for users/owners including what must be done, who is responsible, means to supply service, and benefits.
There are no social conditions that would prevent from the building of the rainfall storage tanks. However, special loans for owners must be arranged because they are not served by the central water system and the people who live in edge of city have low income.
