Additional Baffles Increased the EVF from 0.4 to 0.6 and CT Cap. I.e., the Equiv. Max.-day capacity of the Clearwell is 9.3 MGD, but the EVF is now 0.6 instead of 0.4: 9.3 MGD Equiv. Max.-day X 0.6 = 14.0 Equiv. Max.-day 1 0.4 Now – the Clearwell component capacity no longer limits the Approved Capacity of this 10-MGD WTP 22
<strong>To</strong> Increase the Approved Capacity, the <strong>Water</strong> System could also . . . • Decrease the “Ratio” of Pk.-hour of treatment to Max.-day water production (e.g., install VFDs on both source-water and finished-water pumps), • Decrease the “Ratio” of Pk.-hour water production to Max.-day water production (e.g., construct additional distribution-system storage), • Request a “seasonal CT” approved capacity for the Clearwells (particularly if the Summer, Max.- day water production is significantly larger than the Winter, Max.-day water production) 23
