Proposed IBT Notes:IBT is used to supplement 50 Yr. SY(Available Supply) so that ADD is 80% of increased Avail. Supply in 2010, 2020, and 2035

ASSUMPTIONS:
1.)The WSACC Master Plan indicated for 2000 that ADD WW flows were 88% of ADD water Demand ( or 12% of water demand is consumptive use.
2.)This same percentage is used back to 1992 and forward to 2030 to project expected Consumptive Use
