This presentation summarizes the major environmental compliance steps necessary for the successful permitting/approval of seawater desalination facilities, with an emphasis on desalination plants to be co-located with power generating facilities in California....

Overview on methods for disposal of concentrate / brine from seawater desalination facilities, including open outfalls, beach discharge, subsurface / deep well injection, evaporation ponds, and examples in California and Florida....

In September 2005 California American Water Company (CAW) decided to proceed with a pilot seawater desalination program at Moss Landing near Monterey, California. The objectives of the pilot program are to develop essential design data and to test different technologies and design approaches to facilitate the design of a full-scale desalination pla...

Two examples of development of a water supply for high-end developments in a coastal beach area are discussed in this paper. These developments include five-star hotels, luxury villas, recreational facilities and championship class golf courses. This paper describes the integration of desalination technology to produce several different types of wa...

This paper investigates the efficiency of constructed wetlands for concentrate minimization as compared to traditional evaporation technologies. Using four halophyte species, it is expected that constructed wetlands may increase evaporation/evapotranspiration rates ten-fold....

A 150 gpm temporary desalination pilot facility was designed and installed to determine if potable water could be reliably and economically produced from the San Pasqual GW Basin. Five identical constructed wetland basins, one batch evaporation control and 4 flow through beds with different halophytes. Two Halophytes showed great promise. More rese...

The city of San Diego is investigating brackish water desalination for groundwater sources in the San Pasqual Valley. A three stage NF-RO-RO high pressure membrane system was designed to treat the groundwater. Iron and manganese concentrations in the source water were higher than expected and led to fouling of the membranes. A slow sand filter was ...

The new RO facility will be co-located with the existing surface water treatment plant. The RO permeate will be transferred through a degasifier and scrubber for H2S removal and odor control. The permeate will facility's clearwells, where it will be blended with the filtered water from the existing disinfected, stabilized and transferred to the fa...

This presentation provides an overview of different types of MBRs and recommends selection guidelines for them. Emphasis is placed on different manufacturers and highlights the importance of target water quality; regulatory and space constraints; power and operational requirements; and costs for making a proper selection....

The paper provides design concepts for construction of the tunnel and collector wells, and concludes with a discussion of potential advantages and disadvantages of a DIG intake for this project in comparison to submerged intake, slant wells, or seabed (shallow) infiltration gallery alternatives....

In response to mandated reductions in historical supply sources, California American Water is poised to implement the Monterey Peninsula Water Supply Project (MPWSP) as a sustainable replacement water supply solution on the Monterey Peninsula. The combination of desalination, aquifer storage and recovery, and (possibly) groundwater replenishment pr...
