Expand South Tacoma Aquifer |
The current South Tacoma wellfield contains 13 wells, with a combined
pumping capacity of 45 mgd. In 1995, the assumption of recharge
capability was revised and a new yield was estimated. Tacoma now
believes that the aquifer could provide an additional 29 mgd during
summer months (June 1-November 1). Recent studies also suggest that the
South Tacoma Aquifer could receive annual recharge of approximately
22,000 acre feet. The previous weekly recharge rates were increased
accordingly. Although Tacoma may need to treat this water for use as a
potable source, CRYSTAL does not address this issue. |

Expand Tideflats Aquifer |
The existing well in this aquifer currently produces 1.0 mgd. Recent
studies have concluded that the Tideflats aquifer could produce an
additional 5 mgd. Although Tacoma may need to treat this water for use
as a potable source, CRYSTAL does not address this issue. |

Extract Chambers Creek Property Groundwater |
This property (formerly known as Lone Star Sand and Gravel) has a
combined surface water and groundwater right of 21.8 mgd. Pierce County
currently owns this right. |

Industrial Conservation and Reuse |
In 1997, studies performed to evaluate industrial water conservation
and reuse suggested that water savings were available at the Simpson
Kraft and other industrial mills. Studies estimate that the industrial
mills could reduce demands by up to 9.4 mgd if additional conservation
measures were implemented. An additional 17.2 mgd may be saved if the
mills recovered and reused process water. |
