RE: Customer Water Demand,April 2022
We completed our analysis of the April 2022 billing data and Water Treatment Plant(WTP)pumping
records.Based on that review,we offer the following observations:
• Water conservation for the month of April was 23.82%(see Chart 1)and fiscal year-to-date
water conservation was 24.27%(see Chart 2).
• Historically,customer demand decreases in the month of April. The total water demand for
April was 395.922 million gallons (MG). The total demand for water increased from the
prior month by 45.762 MG. Chart 3 shows the total water pumping over time with seasonal
variations.
co • Total WTP pumping has decreased 4.86% from the 2008-2009 base years even though the
number of active residential customers has increased.
g • Based upon our analysis of the April 2022 residential billing data,we conclude the following
° items:
r
o Tier 1 customers account for 64.7%of total residential customers.
o Tier 1 and Tier 2 customers account for 89.8%of total residential customers.
cc
o Tier 1 customers use an average of 102 gallons per day(gpd).
o Tier 4 customers use an average of 884 gpd, which is approximately eight(8) times
the usage rate of Tier 1.

Customer total reclaimed water demand increased by 26.41 MG from the previous month.In
April, 26.99% of reclaimed water customers had zero usage. The average reclaimed water
demand per customer account was 314 gpd.
Data from the National Weather Service (NWS) at the Jacksonville International Airport (JIA)
indicates rainfall during April was 5.22", which is 2.29"above normal. The mean temperature for
the month of April was 0.1°F above normal.
