Reducing Stormwater Runoff Impacts
U-Tech: Underground Technology Cutting Edge Technical Information for Utility Construction and Rehabilitation
This innovative engineering project reduced the impact to downstream properties by re-directing existing stormwater runoff from a residential community that has historically experienced flooding and saturated ground conditions each winter during severe storm events, to a new surface infiltration facility (Figure 9). The facility was designed in accordance with underground injection control (UIC) regulations. In exchange for the improvements, PWB received property and a permanent disposal point for draining the 3-million and 7-million gallon reservoirs (recently obtained from the acquisition of the Powell Valley Road Water District). Construction began in the spring of 2009 and was completed in the fall of 2009, before the wet weather season began.
