There are other areas of a WRRF that represent potential savings that depend on unique characteristics of the utility. Effective automation can reduce capital costs by allowing staff to maximize existing treatment capacity and facilities, enhance maintenance, reduce equipment wear and damage, reduce chemical usage resulting in reduced chemical storage requirements, and minimize chemical hazards.

Energy efficiency improvements can also yield environmental benefits by reducing greenhouse gas emissions and improving a utility’s carbon footprint. The magnitude of the effect of energy reduction measures on a utility’s carbon footprint is highly dependent on local conditions and the amount of greenhouse gases attributed to the electrical energy source. For example, utilities that obtain electricity from coal-fired power plants will typically have a higher effect than those that obtain a significant amount of energy from renewable sources such as hydroelectric generation.
