§ 33-471. Quantified five- and ten-year conservation goals.

The objective of the City of Waxahachie's Water Conservation Plan is to: (1) Establish water conservation strategies to achieve efficient use of water and reduce the gallons per capita per day (gpcd) consumption of water to meet specified goals. (2) Establish a program to reduce unaccounted-for water in the system and improve the quality of data in water loss estimates expressed in percentage and gpcd to meet specific and quantified goals. The City of Waxahachie is a municipal water supplier with approximately ten (10) major industrial water users, numerous commercial establishments, and continues to experience strong residential and economic growth. The total gallon per capita per day (GPCD) water use for the calendar year 2013 was one hundred eighty-two (182) gpcd, which is not excessive considering there are several major industrial water users in the city and their respective water uses are included in this gpcd calculation. The residential water use for 2013 year was one hundred ten (110) gpcd and the water loss was eighteen (18) gpcd. The gpcd's are not excessive as compared to industry standards, however there is still a need to reduce the water use to provide a more sustainable water supply during drought times. In the calendar year 2013 the City of Waxahachie used a total of 2,111,859,000 gallons of water, with the city's population estimate of thirty-one thousand seven hundred thirty-one (31,731).

Water conservation and water loss goals for the city are as follows:

5- AND 10-YR GOALS FOR WATER SAVINGS

City of Waxahachie

2014 Water Conservation Plan

	Historic 5-yr Average	Baseline	5-yr Goal for year 2019	10-yr Goal for year 2024
Total GPCD	168	168	167	165
Residential GPCD	110	110	109	108
Water Loss (GPCD)	20	20	19	18
Water Loss (Percentage)	12%	12%	11%	11%

 

1.

Total GPCD = (Total Gallons in System ÷ Permanent Population) ÷ 365

2.

Residential GPCD = (Gallons Used for Residential Use ÷ Residential Population) ÷ 365

3.

Water Loss GPCD = (Total Water Loss ÷ Permanent Population) ÷ 365

4.

Water Loss Percentage = (Total Water Loss ÷ Total Gallons in System) x 100; or (Water Loss GPCD ÷ Total GPCD) × 100

_____

The city has set a goal for the maximum unaccounted for water loss in the system to be no greater than eleven (11) percent for the next five (5) years and no greater than eleven (11) percent by 2024. This goal is generally recognized in the utility profession as an acceptable level of unaccounted for water loss. The un-accounted for water for 2013 for the City of Waxahachie was ten (10) percent, with the previous three (3) years ranging from ten (10) to twelve (12) percent and 2009 was at seventeen (17) percent unaccounted for.
