Document Description
EVWD is proposing to construct a 250,000 gallon water reservoir to blend water containing high concentrations of fluoride with water having lower concentrations to generate water that meets State MCL requirements. Historically, water from Well 39 has concentrations of fluoride that exceed State MCL levels. This water has been blended with water containing lower fluoride concentrations from the Intermediate Zone at the two existing reservoirs located at Plant 39. This method of blending is not the most reliable and EVWD is proposing to construct the reservoir with a static mixer to blend water from the well with water from the existing reservoirs. This will be accomplished by installing a pump station to boost water from the existing reservoir. Water from Well 39 will be pumped directly to the new reservoir. The blending reservoir will provide a more reliable and efficient method of blending water for use in the EVWD system. The proposed project does not result in an expansion of use beyond that which presently exists. The project will not increase the capacity of the well or the booster pumps which supply the EVWD system. The project involves construction of a public health protection device in that it will provide a more reliable method of producing water that meets State MCL requirements.
