Water Treatment, Transmission and Distribution
Water treatment technology is evolving rapidly. In addition to the traditional contaminants removed by conventional water treatment, new drinking water quality issues are emerging. Bacteriological, microbiological concerns such as Giardia and Cryptosporidium must be effectively removed while new classes of contaminants are being discovered and evaluated. Emerging contaminants such as NDMA, pharmaceuticals, personal care products and caffeine, are being discovered in raw water supplies throughout the United States. Treatment technologies are being developed that are effective at removing these emerging contaminants. Particulate removal and disinfection can be accomplished in a number of ways including conventional sedimentation and filtration, sand blasted clarification, membrane technology, chlorine dioxide, ozonation, or ultraviolet irradiation. Arber has significant experience with paper research and evaluation, laboratory analysis, bench scale testing and pilot testing of each of these types of technologies that have the potential of being evaluated and incorporated into water treatment systems. Additionally, as transmission and distribution lines age, replacement and rehabilitation of these lines may be required. Further, as service areas are expanded and developed, new lines will be required. Many existing lines are located in developed areas and will result in alternative construction methods including: Lining, pipe bursting and directional drilling.
