The dewatering water would be tested to determine if on-site treatment would be required prior to reuse or removal from the site. The treatment could range from removal of sediment to removal of other constituents. The treated water would be considered for on-site reuse, including use for dust control or mixing with slurry, grout or cement materials. At this time, the volume of dewatering flows and water supplies has not been calculated for each construction site. Therefore, the need for off-site disposal of dewatering flows is not known. However, the dewatering flows would not be discharged to local drainages and stormwater facilities in a manner that would reduce capacity for continued use of these existing facilities by local lands or cause a rise in groundwater and seepage problems on lands adjacent to the drainages.
