RE: Customer Water Demand, May 2022
We completed our analysis of the May 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 May was 18.06%(see Chart 1)and fiscal year-to-date
water conservation was 23.36%(see Chart 2).
• Historically,customer demand peaks in the month of May.The total water demand for May
was 466.7 million gallons(MG).The total demand for water increased from the prior month
by 70.8 MG. Chart 3 shows the total water pumping over time with seasonal variations.
• Total WTP pumping has decreased 18.06%from the 2008-2009 base year' even though the
number of active residential customers has increased.
• Based upon our analysis of the May 2022 residential billing data,we conclude the following
-a items:

L o Tier 1 customers use an average of 101 gallons per day(gpd).
o Tier 4 customers use an average of 868 gpd, which is approximately eight(8) times
the usage rate of Tier 1.

Customer total reclaimed water demand increased by 59.86 MG from the previous month.In
May, 21.43% of reclaimed water customers had zero usage. The average reclaimed water
demand per customer account was 431 gpd.
