Additionally,more <br /> restrictive discharge requirements may require advanced treatment facilities for removal of specific pollutants. <br /> Future capacity needs are based on wastewater flow and load projections. The WQCF and Collection System <br /> Master Plans define facilities that would be needed to accommodate projected flows and loads at City buildout <br /> (i.e., development to the secondary urban service boundary as defined in the 2003 general plan). The proposed <br /> project considers increasing the capacity of the WQCF by 17.13 mgd ADWF. This increase would provide an <br /> additional allocation of 2.52 mgd for the City of Lathrop and 14.61 mgd for the City of Manteca. <br /> Existing treatment facilities have also been designed to be expanded incrementally as future wastewater flows and <br /> loads increase. Consequently, some existing facilities have available capacity for future flows and loads,while other <br /> facilities are near their existing capacity and must be expanded to accommodate increases in permitted flows or <br /> loads. These increments would be large enough to provide reasonable economy of scale and small enough to reduce <br /> the potential for idle facilities.By constructing the proposed master plan facilities in phases,the City can control the <br /> rate of facility expansion if actual growth rates are slower or faster than projected. <br /> The recommended WQCF master plan site layout of existing and proposed facilities is shown in Exhibit 3-6, and <br /> the recommended pipeline alignments of the wastewater collection system master plan and recycled water <br /> Manteca WQCF and Collection System Master Plans EIR EDAW <br /> City of Manteca 3-17 Project Description <br />
