Project Expep4ence <br />treatment, well development, geohydrology, and aquifer storage and recovery, reservoir <br />and transmission facility design, water rights, and public involvement. <br />La Junta 117ate7- Ti-eatn,.ent Plannirzg Project <br />Boyle conducted a pilot plant study to compare the performance of two membrane <br />treatment processes: reverse osmosis and nanofiltration for the City of La Junta. <br />Throughout the pilot study phase, water quality changes in the Arkansas were continually <br />assessed. Prior to final design and construction, a pre- design report, environmental report <br />and funding assistance plan were also developed. <br />The water quality issues in La Junta are significant. The Arkansas River, the City's current <br />water source, exceeds the proposed EPA standards for sulfates and radon, and contains <br />unacceptable levels of hardness. The treatment process ultimately selected must resolve <br />the City's water quality problems, provide a high degree of service reliability and not <br />unduly burden the public works staff. Consequently, Boyle engineers will work closely with <br />the City to ensure proper startup, and continuity during transition of the plant to public <br />works staff. <br />Prior to the pilot plant study phase, Boyle performed a study to quantify and analyze <br />existing water resource data and information to develop a comprehensive <br />recommendation on how to develop the La Junta Water Treatment System over the next <br />20 years. Available water supplies, including groundwater, Arkansas River water, and <br />wastewater reuse were evaluated with respect to quality and quantity. Local water <br />demands were similarly evaluated and alternative supply system configurations to satisfy <br />these demands were prepared. We are recently prepared the final designs for this <br />advanced treatment plant and it is currently in Bid - phase. <br />Denver eater Recyclizzg Pi -oject <br />Boyle Engineering was retained by Denver Water to assist in the development of the <br />Board's Nonpotable Recycling Project, the largest reclaimed water system in Colorado. <br />The $100 million project includes a treatment plant with an ultimate capacity of 45 mgd, <br />and a reclaimed water distribution system that will serve Denver International Airport, <br />redeveloped areas of the former Stapleton Airport and Lowry Air Base, a number of parks <br />and golf courses, and industry/commerce. The water will be used for non - potable <br />purposes, including industrial cooling and turf irrigation. <br />Boyle's role in the project includes applying its nationwide expertise in customer demand <br />and quality requirements, coordinating with State of Colorado regulators, developing a <br />scheme and hydraulic model for the distribution system, and serving as the lead consultant <br />on the project's final design. Boyle is the lead consultant for the design and construction <br />services of the 30 mgd (expandable to 45 mgd) treatment plant, source water pump <br />station, and conversion of an existing potable pumping and storage facility to reuse. <br />Dil lon Mater T7-eati72ent Plant Capacity anti Ti- eabiient Imzproveiizents <br />Located in Summit County, the Town of Dillon has been experienced substantial growth <br />and needed to expand the water treatment plant. The existing conventional plant will be <br />expanded using microfiltration based on ease of operation (mostly automated) and the <br />40 <br />
