Well Design. 2.1 Design considerations 2.2 Well of opportunity

Well Design. Ideally, xxxxx designed for characterization using techniques described in this document should be fully screened across the interval of interest, such as the contaminant plume, be constructed without an artificial filter pack, and be screened such that the top of the screen is far enough below the water table to allow placement of the pump intake in the well casing during the test. Xxxxx et al. (1997) discuss the potential influence of an artificial filter pack on flowmeter results. A coarse-grained gravel or sand pack may result in significant vertical flow through the pack prior to entering the screen. This phenomena is enhanced by use of high flow rates that result in resistance to flow through the downhole probe of the electromagnetic flowmeter. In this situation, the measured flow distribution is skewed with a high influx of water near the top of the screen. For this reason, use of a borehole flowmeter in xxxxx constructed with a filter pack of gravel- sized material may not provide meaningful data and generally should be avoided. It is also possible to observe some effects in xxxxx with filter packs constructed of coarse-grained sand if the hydraulic conductivity of the pack material is significantly greater than aquifer materials. However, use of a natural collapse well construction is not always feasible. For example, formations with a significant fraction of fine-grained materials or units may not be appropriate for natural collapse construction and may result in void space within the annulus that affects test results. Results of field applications of the borehole flowmeter indicate that it is possible to obtain representative flowmeter measurements in many xxxxx constructed using an artificial pack. In general, xxxxx specifically constructed for these tests should avoid use of artificial filter packs, where possible. If an artificial pack is used, the data should be carefully examined for evidence of bias in the flow distribution. Xxxxx that are screened across the water table may be subject to increased head loss near the pump intake. This is particularly true for xxxxx constructed with an artificial filter pack that is significantly more conductive than surrounding aquifer materials (Xxxxx et al., 1997). This situation may result in a nonuniform head distribution in the well and an increased influx of water near the pump intake. Such a situation would also bias flowmeter test results. Presence of a low permeability skin (i.e., positive skin ef...

Well Design. The CONSULTANT will provide pump sizing and design capable of serving the project site from the irrigation aquifer well. It is the CONSULTANT’s understanding that the well will feed the irrigation mains directly. The CONSULTANT will perform limited hydraulic modeling sufficient to design and size the well pumps and piping. Hydraulic model will be based on irrigation demand and minimum operating pressures determined in the irrigation design task herein. The VILLAGE understands finished well yield may vary due to site-specific aquifer characteristics. The mechanical piping specification of materials will be based upon the VILLAGE’s standard specifications (if applicable). It is assumed a suitable location for the well can be found within the existing Xxx County owned ROW, or contiguous VILLAGE owned property, and that Xxx County approves of the use and well construction in that location. The CONSULTANT shall provide post design services to include response to questions during bid, response to RAI’s and provide clarification and interpretation of the plans.

Well Design. This is a new Task. Well design shall be completed by CONTRACTOR’s sub-contractor, Xxxxxxx Hydro-Xxx-Logic, P.C., and electrical design by CONTRACTOR’s sub-contractor, Aurum Consulting Engineers, Inc.
