SECTION 9WASTEWATER FLOWS9.1 GeneralWastewater flows are generated from domestic, industrial, and commercial uses.Inflow and infiltration are terms used to describe the groundwater and stormwaterseepage. Inflow enters the system at direct connection points while infiltration isthe groundwater that seeps in through cracks and leaks in the system.The domestic water that is returned to the treatment facility comes from sinks,showers, tubs, lavatories and toilets. In an average system, 60% - 90% of thepotable water is directed to a wastewater treatment facility or an on-site septicsystem. Water not returned to the wastewater treatment plant is typically used forirrigation and industrial applications.The rate of return flow determined for the study was developed by comparing theaverage daily water use and average daily wastewater flow. Lockhart and Lulingwere the only systems that had data available to evaluate.9.2 Wastewater FlowsLimited wastewater flow data exists for Caldwell County. Large portions of thecounty are served by OSSF systems that are regulated by the County or city.Lockhart and Luling provided the only data in the survey to determine averagedaily wastewater flows and peak flow factors. The average daily wastewater flowranged from 0.4 MGD to 1.2 MGD with an average of 0.8 MGD. The averageflow was considered to be the base flow and the peak flows considered asinfiltration and inflow.Given the sewer base flow and population, a per capita value was determined. Thesewer populations for Lockhart and Luling were estimated to be 13,464 and 4,9789-1Klotz Associates Project No. 0972.000.000Caldwell County Regional Water and Wastewater Planning StudyJanuary 2010Final Report
