This powerpoint presentation begins by providing background information on Tampa Bay Water that includes: historically groundwater supply-oriented;
extensive water supply litigation in 1990's
related to environmental degradation;
agency reformed in 1998 as Tampa Bay
Water;
permitting tied to reformation;
groundwater reduction agreement; and,
Master Water Plan developed for
alternative water supply sources. The presentation outlines how historical events supported the need for improved
water shortage planning, along with Water Shortage Mitigation Plan (WSMP) trigger criteria should be based on
supply reliability, and Enhanced Surface Water System (ESWS) supply reliability drives the need for a shortage plan. Water Shortage Mitigation Plan (WSMP)
objectives include:
can water shortage definitions be linked to
conditions corresponding to high risk of
surface water supply exhaustion; and,
can mitigation activities (demand
reduction, supply augmentation)
quantifiably reduce risk of surface water
exhaustion? Objectives for WSMP Triggers include:
Level 4 Water Supply Crisis - critical water supply
shortage, ESWS shutdown imminent;
Level 3 Water Shortage - extreme water supply
shortage, reduced ESWS reliability with decreasing
reservoir elevation;
Level 2 Drought Warning - reduced rainfall and
stream flow, reservoir storage adequate but
decreasing; and,
Level 1 Drought Alert - reduced rainfall or stream
flow, indicating potential for water supply shortage. Development of water shortage levels and
triggers,
demand management actions, and
supply management actions are all presented.
