Arkansas - Las Animas Water System Improvements_Water Activity Summary

Home Browse Search

As of September 2006, the city has a total of 1,188 water customer taps, which breaks down to 1,046 residential taps and 142 commercial taps. Based on these users, the city’s existing average day water demand is 429,682 gallons per day (gpd) with a maximum day demand of 935,000 gpd. Based on the fact the neighboring correctional facility is in the middle of an expansion coupled with the projected population increase, the city’s corresponding water demands will increase. Increases are expected to jump to 546,700 gpd for an average day demand while the maximum day demand is anticipated to increase to 1,157,200 gpd by year 2030. In order to meet this increase in demand, the city has both in place and is making provisions for upgrades to a wide range of facilities. Currently, the city derives its water supply from ground water sources, which consist of 11 wells. Out of the 11 wells, the city currently only uses seven of the wells for the city’s potable water supply. These wells are classified as non-exempt, tributary wells, which require augmentation. Raw water is pump to the city’s water treatment plant (WTP). Reverse osmosis treatment is provided at the WTP. The treated water flows into a large ground level storage tank. The potable water is then boosted into an elevated water storage tank and the distribution system. The distribution system provides a network of piping throughout the city’s service area. The elevated water storage tank provides gravity storage and maintains relatively constant pressures within the distribution system. The City of Las Animas has undertaken a comprehensive Preliminary Engineering Report evaluating its water system. The study was expanded to cover the water treatment plant (WTP) as a result of the local correctional facility’s proposed expansion that will more than double its capacity. Construction on the expansion is in progress. The net affect of the correctional facility attaining its inmate expansion will be the city’s inability to provide sufficient treated water to all of its constituents during high demand periods. Such being the case, the city’s existing WTP will need to be expanded through the addition of another reverse osmosis (RO) train or secondary recovery. The project is needed for multiple reasons. The city needs to be in a position where it can comfortably provide water service during high demand conditions. The city’s WTP will be stretched beyond its capacity with the doubling in size of the local correctional facility. Furthermore, the city needs to have the facilities in place to obtain the raw water it is entitled to in addition to conveying said raw water to its water treatment plant. To accomplish such, the city needs the addition of a third reverse osmosis (RO) train in its WTP, needs to re-drill an existing well and install a new parallel transmission line to convey raw water to the WTP. This will bring an economic boost to an area suffering from years of natural disasters, economic hardship and the transfer of water rights out of the basin. Any form of job creation within the area and even the region is more than welcome and strongly pursued. The overall goal of the project is to bring about the provision of acceptable quantities of water with good water quality and the ability to convey the water to the constituents in the community with a system that is reasonable to operate and maintain. These facilities will bring about economic development within the city and the surrounding region by the doubling in size of the Corrections Corporation of America (CCA) Correctional Facility, the local correctional facility. The scope of work to be accomplished within this application includes the following: 1.Installation of a third reverse osmosis train or provide secondary recovery on the waste stream within the existing water treatment plant to meet all demands placed on the water system. 2.Provide raw water at the rate required to meet demand, which results in the need to bring one of the non-operational wells back online coupled with the installation of a new transmission line to the water treatment plant. 2
