Water System Supply and Demand
*Maximum available water supply: C/A WTP Maximum Sustainable Operating Capacity is 16.00 MGD, Raleigh Maximum Water Purchase of 4.5 MGD, **Maximum water capability from Durham through Davis Drive pump station is 4.2 MGD (at normal operating pressures), and Apex purchase from Raleigh is 0.23 MGD. The maximum available supply from C/A WTP has been increased to 16.00 MGD due to recently completed raw water pipeline upgrades.
** Cary's Durham water purchase is contractually 3.5 MGD, with a variance of 80% to 120% (or 2.8 MGD to 4.2 MGD). Morrisville's water purchase which comes through the Cary system is contractually 1.5 MGD, with a variance of 80% to 120% (or 1.2 MGD to 1.8 MGD).
*** Rainfall data is from the Raleigh Durham Airport vicinity and does not reflect local isolated showers. "T" stands for trace and is not measurable.
