7.1.A. - Page 19 <br /> 75 to 88 feet in diameter and 24 to 32 feet in height.The size of a 2 mg reservoir ranges from 95 <br /> to 125 feet in diameter and 24 to 40 feet in height. The reservoirs may be partially buried or <br /> aboveground, depending on site characteristics, and would be painted an earth-tone color. A <br /> recycled water pump station would be located adjacent to each reservoir. It is anticipated that <br /> the pump station will be constructed aboveground, and housed within an acoustically-treated <br /> structure designed to be compatible with surrounding land uses. If minor modifications to the <br /> assumptions about the reservoirs and pump stations occur during detailed design of these <br /> facilities, the City will determine if supplemental environmental review is required for those <br /> modifications. <br /> Recycled Water System Operations <br /> Recycled water use is strictly regulated to avoid public health risks. Water reclamation criteria <br /> are established by the California Department of Public Health to specify requirements for <br /> recycled water by category of use. Title 22 of the California Administrative Code contains <br /> standards for water quality, monitoring, reporting, and treatment reliability. These criteria are <br /> enforced by the RWQCB to ensure that recycled water projects are safe, reliable, and protective <br /> of public health. <br /> Recycled water produced by the SBSA treatment plant is treated to meet the "unrestricted use" <br /> standards as defined by Title 22. Throughout the wastewater treatment process, samples are <br /> taken and tested in an onsite laboratory to ensure high quality water is produced. The level of <br /> treatment at SBSA enables the recycled water to be used for many purposes, including irrigation <br /> of park and playgrounds, median strips, commercial landscaping, residential landscaping, golf <br /> courses, roadway landscaping, ornamental nursery stock, and sod farms. <br /> Other permitted uses include toilet and urinal flushing, recreational impoundments, firefighting, <br /> industrial processes, dust control, cooling towers, and decorative fountains. As described above, <br /> the Redwood City Recycled Water Project intends to use the water primarily for irrigation of <br /> public and private landscaped areas and medians, to serve some industrial customers, and <br /> possibly for toilet flushing and firefighting. <br /> Operation of the recycled water distribution system is similar to operation of the existing <br /> potable water distribution system, with the addition of required safeguards for use of recycled <br /> water. Consistent with Title 22 regulations, signs are posted to notify the public of areas where <br /> recycled water is being used. These signs, and the pipelines and valve facilities, are purple in <br /> color, to denote that recycled water is in use. <br /> As with the First Step Project, the City will continue to provide information and assistance to <br /> eligible recycled water customers in the expanded service areas of the project. For landscape <br /> irrigation customers, this assistance is in the form of: <br /> • Site evaluations <br /> • Soil and plant tissue analysis and recommendations <br /> 5 <br />
