An existing, historic, city water works site of many acres adjoining a major river is offered for a public art proposal. My approach is to analyze, plan and design around four basic types of structural systems: 1) stochastic, 2. proportional, 3) programmatic, and 4) dynamic. The river of rapid current feeds the water system's need for unceasing flow to a major metropolis - water means life. The functions of purification, pumping, treatment, stabilization, filtration and distribution are fundamentally turbulence.
