H. Existing/Projected Water And Sewer Demands - Water and sanitary sewer
demands were developed using the estimated I998 population of the area and the
projected growth through the Year 2020. Demands were based upon design values for
water and sewer utilized by the Texas Natural Resource Conservation Commission
(TNRCC). These design values are I20 gallons per capita day for average daily water
demand and I 00 gallons per capita day for average daily wastewater demand. Peaking
factors for both water and sewer flows were used to estimate peak daily demands
Projected average daily water demand for the service area is estimated to increase from
138,000 gallons per day (gpd) in I998 to 264,420 gpd in the Year 2020. Similarly,
average daily sewer flows are estimated to increase from II5,000 gpd in I998 to
220,350 gpd in the Year 2020. For the purposes of this study, the water distribution and
wastewater collection systems were evaluated for the current demands within the area
and the projected demands in the Year 2020. In addition to the average daily demands,
peak hour water demands and design fire flows defined by the State Board of Insurance
are utilized in the water system design Peak wastewater flows are developed for lift
station design.. The water and sewer demands calculated for the planning area are
presented in the following Table.
