Title

Junction City Elementary School Water Filtration and Treatment System Upgrade Project

Description

The Junction City Elementary School District (JCESD) water system provides potable water to approximately 80 students and staff during the school year. Water demand increases during special events and on occasions when the school serves as an emergency relief staging area during wildland fires. The existing water treatment and filtration system was constructed in 1990 and is over 30 years old. The water source for the school are two wells located immediately adjacent to the Trinity River; therefore, the water source is considered to be a surface water source, and is treated using a conventional filtration process and then disinfected using a solution of sodium hypochlorite. The treated water is stored in a 12,000-gallon welded steel water storage tank and then booster pumped using a hydropneumatic tank to maintain pressure throughout the school. The JCESD does not currently have an emergency power generator on site for the water treatment plant (WTP). Additionally, there are several components of the water treatment system that have failed or are at the end of their useful service life and risk failing soon. The purpose of the proposed project is to provide potable drinking water to the students, staff, and others that use the facilities. Proposed improvements to the JCESD water filtration and treatment system include retrofitting and upgrading the WTP by replacing filtration media, pumps, and appurtenances; recoating the interior and exterior of the WTP unit and the 12,000-gallon storage tank; installing a new concrete pad, 150-kilowatt propane-fueled emergency power generator, automatic transfer switch, two 1,000-gallon propane tanks, and fencing around the equipment; and constructing a concrete or block (concrete masonry unit) retaining wall. Temporary water filtration and storage tanks would be installed during construction to supply the school with a water supply. The temporary water filtration process would be removed upon project completion, or it could remain in place as a permanent backup filtration process in the case of an emergency. Staging of materials and construction equipment would occur at the project site. Site grading and removal of two trees would be required to facilitate the installation of the generator and propane tanks.
