About

The western Placer County region including the City of Lincoln have been among the fastest residential and commercial growth areas of California for the last several years, The increased treated water demand associated with the growth is requiring domestic water purveyors in the area, including the Nevada Irrigation District (NID) and the City of Lincoln, to increase treated water production capacity to continue to provide treated water service. NID's service area includes portions of Placer, Nevada and Yuba counties. A portion of the service area overlaps the City of Lincoln's sphere of influence (SOI). The City of Lincoln's 2005 General Plan Update estimates that approximately 20,000 homes will be constructed within the portion of the District's service area that overlaps the City's SOI over the next fifty years.

To address the projected demand, NID and the City of Lincoln joined in a cooperative study to identify a site for a new water treatment plant to serve the portion of the City of Lincoln within the NID service area, as well as unincorporated areas outside the City of Lincoln. The addition of the new water supply to the City of Lincoln, in conjunction with the City's groundwater well network, and the service from placer County Water Agency will provide the City treated water capacity through the planned build out included in the 2005 General Plan Update, Phase 1 and Phase 2.

The goal for this project was to identify the most appropriate site for the water treatment plant taking public comment into consideration. In addition to the water treatment plant itself, several related improvements and facilities were identified and included in the overall evaluation. Examples include primary and back up raw water supplies, and conveyance pipelines/canals and storage facilities. Therefore the water treatment plant site evaluation is a comparison of various combinations of treatment plant sites and supporting facilities. During the study, it became apparent that phasing of improvements would be necessary to finance and implement the project.

In 2008 and 2009, a series of public meetings were held in Auburn, Nevada City and Lincoln to introduce the public to this project. Comments were collected and incorporated into the selection of alternatives for raw water pipeline and treatment plant location.

Currently, the project is entering into its environmental phase where detailed review of potential impacts takes place. Part of this process will include a formal public comment period likely to occur in Spring or Summer 2014. Prior to this, NID is holding three public information meetings (Feb. 18, 20 and 25, 2014) to introduce current developments, the project timeline and methods of public involvement. Our goal is to encourage the public to raise any and all questions early on in the process so that the biologists and other scientists on the team will adequately study all possible environmental impacts and suggest methods to mitigate or avoid them altogether.
