Question

A drastic turnaround in WSU’s football program has created national and international recognition of WSU. Enrollment has increased significantly, and many new staff and faculty have been hired. As a result, the City of Pullman’s previous population projections are no longer accurate. Find the total capacity of the water towers (reservoirs) in Pullman from the website. Assume this capacity is for one day of usage. Using the City’s 1990 census population, assume it is increasing geometrically to 40,000 in 20 years. In how many years will the demand exceed the water towers’ capacity? Use the same average daily usage that you used in question 3 above.

Total capacity of water towers = 7.7 million gallons

1990s census population = 23,478
