Footnotes
(a) Annual Average Daily Demand (AADD) Finished Water Projections between 2007 and 2030 assume 155 gpcd total water system demand prior to application of credits (e.g. conservation).
(b) WASD will be undertaking the 20-year water use efficiency plan and expects reductions in per capita water consumption. Water Conservation projections were taken from comments
MDWASD submitted to SFWMD on 4/6/2007. Values reflect projections as of 4/6/2007. Real losses in non-revenue water (e.g. unaccounted-for-water) are assumed to remain at less than 10%.
(c) Tentative Alternative Water Supply Reuse/Reclaimed Water Projects to replace finished water demand. Items 1 and 2 result in credits that reduce finished water demands (demand management).
1. North District WWTP Reuse Projects. This excludes the 5 mgd that will be used by the City of North Miami Beach. See CIE Table 8, Project 29.
2. Central District WWTP Reuse Projects. See CIE Table 8, Project 30.
Total (est.)
(d) Adjusted after taking credit in finished water demand projections for reductions in finished water use associated with water conservation and reuse (demand management).
(e) South Dade (Raw : Finished) Ratio = 1.0 : 1.0
(f) Membrane Softening (Raw : Finished) Ratio = 1.25 : 1.00
(g) Beginning 2014, withdrawals from SMH WTP are considered offsets from Phase 1 GWR (23 mgd) near SMH (Metro Zoo)
(h) Base condition water use (347.0 mgd) represents values agreed to by SFWMD and MDWASD. Biscayne Aquifer base condition water use of 347.0 mgd equates to 340.34 mgd of finished water annual average daily demand (AADD) assuming a 1.02 raw-to-finished water ratio. Begining in 2012,
the base conditions water use is increased by 1 mgd to 348.0 mgd to account for the new reverse osmosis membrane softening treatment at SMH WTP in accordance with the SFWMD Water Availability Rule. South District Wastewater Treatment Plant (SDWWTP) Reclaimed Water Projects for
Groundwater Recharge (GWR) as shown in the table below and assuming a gallon-for-gallon offset. The applied (MGD) amounts represents total Biscayne Aquifer withdrawals to apply a gallon-for-gallon offset.

(j) Lime Softening UFA Blending (Raw : Finished) Ratio = 1.02 : 1.00 (Subject to ongoing field verification and subsequent adjustments.) MDWASD is in the process of improving its raw water metering/accounting system, which may result in an adjustment to the historical raw water
values.
