1. Water Supply <br /> The project will be served by a public water system (nontransient, noncommunity water system, <br /> pursuant to Health &Safety Code section 116275(k).) Test wells have been drilled to determine <br /> water quality and quantity to service the project. The test wells indicate there is ample water to <br /> meet the future development's needs. In addition,the water quality indicates that no treatment is <br /> necessary to meet the state requirements for water quality for a nontransient noncommunity <br /> water system. Prologis has elected to treat the well water to make it more acceptable for domestic <br /> use and limit issues with onsite wastewater disposal. Two wells will provide the necessary water <br /> required for the project and will pump to the water treatment facility. The treatment facility will <br /> consist of a treatment and pneumatic disinfection system, brine processing and holding building, <br /> water processing tank, brine drying beds, and miscellaneous maintenance and equipment storage <br /> buildings. <br /> 2. Domestic water system <br /> The domestic water treatment system is anticipated to be an ion exchange system to provide for <br /> the additional level of treatment to increase the acceptability of the water and to decrease mineral <br /> deposits. Initial water quality tests indicate elevated levels of Calcium, Iron, Magnesium and <br /> Manganese. Prologis will establish an operational and funding entity or contract with an agency <br /> like the Byron Bethany Irrigation District to provide for the maintenance of the system as a public <br /> water system. <br /> 3. Fire water system <br /> A storage tank will provide for the necessary capacity for fire protection for the project. The fire <br /> water system permit will be through the San Joaquin County and will need to meet the regulations <br /> of the local fire department,which is Rural Tracy Fire. Supplying the fire system with recycled <br /> water has also been considered. Booster pumps will be required at each building to provide for the <br /> required pressure for the interior fire sprinkler systems. <br /> 4. Wastewater system <br /> Wastewater will be treated and disposed of onsite and will consist of a wastewater treatment <br /> facility, sludge drying facility, and a recycled water tank. The treated wastewater will be stored on- <br /> site and become the primary source of irrigation water for the development. With the well head <br /> treatment anticipated and discussed above,the solids from the wastewater system are minimal <br /> and can be used as fertilizer for the landscaping within the development. Permitting from the State <br /> for the wastewater system is anticipated to be completed concurrent with the permitting of the <br /> potable water system. <br /> 5. Recycled water <br /> As discussed above,wastewater will be treated to the necessary requirements to be used for the <br /> landscape irrigation of the site. The proposed treatment system for the potable water system and <br /> the proposed wastewater treatment (MBR plant) has been utilized at other similar locations and <br /> uses within the State. The treated water quality will meet or exceed Title 22 of the California Code <br /> of Regulations, and thus it is anticipated the recycled water system will be a standard approval <br /> process. An on-site "purple pipe"system will be designed and installed to provide irrigation water <br /> for the project. Additionally, recycled water may be used to support the fire system water supply. <br /> Page 4 of 5 <br />
