Why rely on pumps for backwash in lieu of the water tower?

Backwashing via pumps and/or elevated towers are common method of providing backwash water to the type of filters proposed. The concept design started with pumps for direct backwash water supply due in part to the time and cost for maintenance of pumps versus pumps plus elevated towers plus flow control. During design, it was thought that the capital cost of elevated storage with lower horsepower pumps would be less than direct pumping. Costing of the project found the direct pumping for backwash to be a lower capital cost. Direct backwash pumping allows for a lower capital cost, a lower maintenance cost, and the pumps may be dual-purposed for finished water pumping.
