Water Source Additions -Project No. 14196
<br />Capital projects for Water Source Additions include projects that relate to the existing Hayden
<br />Bridge intake and any work that maybe included with the fish hatchery intake. Starting in 2003,
<br />a study will be conducted to assess the existing Hayden Bridge Intake on the McKenzie River to
<br />identify Capital Upgrades for the structure, piping, pumps and screens.
<br />Another study on the horizon will be a cursory look at whether infiltration galleries on the
<br />McKenzie River will be feasible to hedge high turbidity events and hazardous spills.
<br />Approval for the development of groundwater as a backup water supply is also included in this
<br />project. Wellfield development will occur over the next five to ten years. Land acquisition for
<br />groundwater is included in the Land Acquisition Project (No. 15377)

<br />Project Description:
<br />Well fzeld Development
<br />The first well field is to be developed by 2004. In 2002, the monitoring wells and two production wells have
<br />been drilled. The 2003 budget includes more drilling of wells, construction of pipeline infrastructure and well
<br />houses. Currently, EWEB plans to dri115 to 7 wells for a total back-up supply of 10 to 15 MGD.
<br />ORIGINALLY, EWEB planned to construct the well field in two phases. However, further investigation
<br />concluded that the best approach to achieve the needed quantities of back-up supply, as soon as possible, was to
<br />combine the two phases. There is a contingency of $3,260,000 for potential treatment of arsenic and radon for
<br />the groundwater project. At this point, we are not planning to treat groundwater other than to disinfect to meet
<br />water quality standazds. This contingency is not reflected in this estimate. However, this contingency has been
<br />included in our bonding authorization in case it is needed. Refer to the December 2000 Groundwater
<br />Exploration study report for further details. _
