This powerpoint presentation begins by providing a brief overview of the drivers for watershed-based performance standards. Project background information includes a brief overview of BWWB, the largest
water utility in the state
of Alabama, providing
water to over 675,000
customers.
It operates two reservoirs
and two "run-of the river"
water sources, with
development mostly
prevalent in the Cahaba
River/Lake Purdy
watershed. Challenges for watershed protection are presented, and the approach, or technical basis of the plan included: evaluate present operation
at the Shades Mountain
filter plant relative to
historical/existing water
quality conditions;
evaluate point and non-point
sources that drive reservoir water quality (WQ);
determine changes in
water quality that will
significantly increase operation and maintenance
costs and/or necessitate
major capital
improvements;
evaluate reservoir WQ
(assimilative capacity); and,
develop watershed protection
policy that minimizes the risk of
the threshold identified in step 2
being exceeded. Present operational costs, treatment plant impacts, basis for watershed protection, watershed protection policy focus, and applicability are all presented. Includes tables, figures.
