MIUS technology evaluation: water supply and treatment

Water treatment is one of the services which may be performed within a Modular Integrated Utility System (MIUS). A MIUS can serve from 100 to 3000 dwelling units and their associated facilities. The small size and self-contained nature of a MIUS create special situations with respect to the application of innovative water treatment and distribution technologies. This report evaluates current and future technology on the basis of its suitability for application as part of a MIUS development. A MIUS may include water treatment for domestic use or fire protection. The conventional technology evaluated in this report is, for the most part, appropriate to the treatment of surface water supplies, and the small pre-engineered plants described are designed primarily for surface water treatment. In some situations separate components, rather than a complete pre-engineered plant, may be most appropriate when designing a MIUS supply. A MIUS must provide adequate disinfection as a part of the treatment process, and in some cases a desalting process is necessary. The cost of water treatment will vary as a function of water source quality and use. In order to insure adequate plant operations, personnel must be provided in accordance with appropriate regulatory agency standards. Some automationmore » may be possible, but it is doubtful that all manpower can be eliminated. Improper operation or maintenance can result in water unfit for human consumption or other MIUS uses.
