ATTACHMENT B <br />Veneta/EWEB Pipeline <br />Project Overview <br />April 5, 2010 <br /> <br />The City and EWEB have been in talks over the last two years regarding the potential for <br />EWEB to supply water to Veneta in an arrangement similar to EWEB’s existing <br />wholesale contracts with various water districts. In February 2008, EWEB produced a <br />report entitled A Concept of Regionalization: Water Sales to the City of Veneta, which <br />explored, in some detail, the logistics of building a 24” diameter pipeline from the current <br />western terminus of EWEB’s system at Terry Street, to the Veneta water treatment <br />facility on East Broadway. <br /> <br />This work was conducted concurrent with the City’s update of its Water Master Plan <br />which was adopted in May 2009. This plan examined several potential water sources for <br />the City, including continued groundwater exploration. This study concluded that <br />groundwater development alone was not likely sufficient to meet the City’s long term <br />needs for a population of almost 10,000 residents in 2030. Unlike communities along the <br />Willamette River, Veneta is located at the foot of the coast range, an area composed <br />largely of fractured silt and sandstones, rather than layers of alluvial material which <br />readily and reliably transmit large volumes of high quality groundwater. These siltstones, <br />known as the Tyee formation, are extremely difficult to extract water from. Mineral <br />deposits vary greatly from place to place and drastically affect water quality, and it’s very <br />difficult to predict the location of productive well sites due to the fractured nature of the <br />rock. This all adds up to a water exploration program that is both extremely expensive in <br />terms of exploration and development and unpredictable as to quality and quantity. Even <br />though the City has developed three new wells and a satellite treatment facility since <br />2005, there have been instances in recent years where peak demand has outstripped <br />production. Fire capacity and redundancy for emergency purposes has been less than <br />desirable, a situation that greatly concerns City staff and elected officials if our <br />community is to return to the level of self-sufficiency we experienced in the early 80s and <br />90s. <br /> <br />All indications are that the highest potential for productive wells lies east of the Veneta <br />UGB. Expansion of well fields into this area may present additional problems related to <br />potential impacts on both surface waters such as Coyote Creek, and on existing <br />residential and agricultural wells. Water right restrictions on local surface waters, <br />including the federal storage at Fern Ridge Reservoir, make use of that water unlikely at <br />best, and other options such as new impoundments have political and environmental costs <br />that are simply too high to consider. <br /> <br />The City essentially has two options; continue developing groundwater sources within <br />and adjacent to the UGB as our sole supply, or connect to EWEB to supply the majority <br />of our demand. Both the City and EWEB feel that it is important to retain our existing <br />system to provide redundancy in case of emergency, and depending on the structure of <br />relationship, to supply peak demand as well. Veneta’s projected peak month demand in <br />
