<br />Auamentation Storaae <br /> <br />The City will require both Fulton Ditch and Windy Gap effluent storage. Since the <br />Fulton Ditch typically operates from April through October, having storage will allow the <br />City to store excess Fulton Ditch credits during the irrigation season and divert the water <br />back to the river in the winter months or other times of need. Under current projections, <br />the City will need 200 ac-ft of Fulton Ditch storage. The City has received 100 ac-ft <br />through an agreement with a developer building a storage reservoir and has the option <br />to purchase another 100 ac-ft within the same storage vessel. <br /> <br />Table 5.5 - Fulton Ditch Storage, Opinion of Probable Construction Costs <br /> <br />Item Quantity Unit Unit Cost Item Cost <br />Mob/Demob and general contract requirements 1 LS $50,000 $50,000 <br />Earthwork, grading and misc. sitework 1 LS $50,000 $50,000 <br />Raw Water Storage 100 ac-ft $2,500 $250,000 <br /> Subtotal $350,000 <br />Design and Construction Contingencies (200/0) $70,000 <br />Contractors Overhead and Profit (150/0) $52,500 <br />Construction Cost Subtotal $472,500 <br />Engineering - Design Phase Services (80/0) $37,800 <br />Engineering - Construction Phase Services (40/0) $18,900 <br /> Total $529,200 <br /> <br />The City will also need 500 ac-ft of Windy Gap effluent storage. This storage allows the <br />City to maximize the reusable component of the Windy Gap water right. The City is <br />presently negotiating 100 ac-ft with a developer. If the City is successful, the City will <br />need to purchase an additional 400 ac-ft of effluent storage. <br /> <br />Table 5.6 - Windy Gap Effluent Storage, Opinion of Probable Construction Costs <br /> <br />Item Quantity Unit Unit Cost Item Cost <br />Mob/Demob and general contract requirements 1 LS $100,000 $100,000 <br />Earthwork, grading and misc. sitework 1 LS $50,000 $50,000 <br />Raw Water Storage 400 ac-ft $3,500 $1,400,000 <br /> Subtotal $1,550,000 <br />Design and Construction Contingencies (200/0) $310,000 <br />Contractors Overhead and Profit (150/0) $232,500 <br />Construction Cost Subtotal $2,092,500 <br />Engineering - Design Phase Services (80/0) $167,400 <br />Engineering - Construction Phase Services (40/0) $83,700 <br /> Total $2,343,600 <br /> <br />The City potentially could use one of its wastewater lagoons to develop storage. <br />Storage at this location is ideal because the water can be gravity fed from the WWTP to <br />the storage vessel and subsequently released by gravity to the river. It is estimated that <br />80 ac-ft of storage could be built at the WWTP lagoons. <br /> <br />Clear Water Solutions, Inc. <br />City of Fort Lupton <br />2007 Water Conservation Plan <br /> <br />33 <br />
