The Water Quality Study also recommended improvements to the handling of residuals which are a normal byproduct of the water treatment process. These recommended improvements will be designed and constructed in phases at the ESWTP. Once completed, they will allow for the separation of residual streams and will improve the quality of water recycled in the plant. In turn, this will improve the efficiency of the treatment process and allow for a more continuous and consistent residual handling operation. Since the early 1990s, ESWTP has primarily used a system of five on-site lagoons for residual management. The existing lagoons are nearing their ultimate capacity and the construction of new residual handling facilities will extend their useful life and provide flexibility in the future operational use of the lagoons.
This action will authorize construction of the first phase of new residual handling facilities at the ESWTP. Im...
