(A) Data is tracked by utility staff on a daily basis and organized to be able to track water production and deliveries to the highest practicable levels.
(B) Population. The population of the city has increased steadily throughout its history. The approved 2021 TWDB and Region L population projections, shown below, predict that the city will have over 18,000 residents by 2070.
(C) Water system. The city currently serves 4,592 connections. There are 1,850,000 gallons above ground storage in four elevated storage tanks and 2,350,000 gallons of ground storage. The city operates seven wells.
(D) Wastewater system. The city owns approximately 90 miles of collection system, five lift stations, and one wastewater treatment plant.

Treated effluent is discharged from Outfall 001 via an 18-inch pipe into the Atascosa River in Segment No. 2107 of the Nueces River Basin. Designated uses for this segment are high aquatic life uses, public water supply, and contact recreation. The plant has an average flow of 0.734 million gallons per day (MGD) and a two hour peak flow of 1,219 gallons per minute (GPM). The permitted maximum daily flow is 1.42 MGD and the maximum two hour peak flow is 2,958 GPM.
(E) Water supply. The City of Pleasanton obtains 100% of its water from groundwater wells in the Carrio-Wilcox and Queen City aquifers.
(F) Water demands. The city has averaged 630 million gallons (1,923 acre-feet) of water use annually over the previous five years.

(H) Per capita water use. Per capita water use is generally expressed in gallons per customer per day (GPCD) and is the average amount of water used by each person in the population served by a water utility. Variables that can influence GPCD include the relative amount of non-residential water uses, the rate and type of growth, economics, climatic conditions, and demographics. Residential GPCD is a superior metric measurement for understanding how much water each resident is actually using and does not include commercial and industrial uses. Currently, the city’s total GPCD is 166 and the residential GPCD is 83.
