Section 3 Water Sources and Supply Reliability Metropolitan’s primary sources face individual water quality issues of concern. The CRA water source contains a higher level of total dissolved solids (TDS) and a lower level of organic material while the SWP contains a lower TDS level while its level or organic materials is much higher, lending to the formation of disinfection byproducts. To remediate the CRA’s high level of salinity and the SWP’s high level of organic materials, Metropolitan has been blending CRA water with SWP supplies as well as implementing updated treatment processes to decrease the disinfection byproducts. In addition, Metropolitan has been engaged in efforts to protect its Colorado River supplies from threats of uranium, perchlorate, and chromium VI while also investigating the potential water quality impact of emerging contaminants, N-nitrosodimethylamine (NDMA) and pharmaceuticals and personal care products (PPCPs). Metropolitan has assured its ability to overcome the above mentioned water quality concerns through its protection of source waters, implementation of improved treatment processes, and blending of its two sources. While unforeseeable water quality issues could alter reliability, Metropolitan’s current strategies ensure the deliverability of high quality water. Table 3-15 shows the amount in acre-feet per year that water quality would have on supply. Table 3-15: Water Quality – Current and Projected Water Supply Impacts (AFY) Fiscal Year Ending Water Source 2010 2015 2020 2025 2030 2035 Metropolitan 0 0 0 0 0 0 3.7.3. Normal-Year Reliability Comparison MWDOC’s service area receives imported water from Metropolitan via the regional distribution system. Although pipeline capacity does not guarantee the availability of water, it does provide the ability to convey water when it is available to the member agencies. Imported water supplies discussed in this section can be conveyed to MWDOC’s service area by existing water transmission facilities. Table 3-16 shows supply and demand under normal year conditions to be fully reliable. Additional water supplies are projected to be available from Metropolitan, if needed.

Single Dry-Year Reliability Comparison MWDOC’s service area is projected to be 100% reliable for single dry year demands from 2015 through 2035 with a demand increase of 6.6% using FY 2001-02 as the single dry year. Table 3-17 compiles supply and demand projections for a single dry water year. Additional water supplies are projected to be available from Metropolitan, if needed.

Multiple Dry-Year Reliability Comparison MWDOC’s service area is projected to be 100% reliable in multiple dry years from 2015 through 2035 with a demand increase of 6.6% in each of the three years using FY 2001- 02 as the basis of the multiple dry year projections. Table 3-18 shows supply and demand projections under multiple dry year conditions. Additional water supplies are projected to be available from Metropolitan, if needed.
