Info

Future growth in Caldwell County will increase wastewater production to anestimated 10.2 mgd. If 70 percent of the wastewater is treated by regionalwastewater treatment plants, the volume of wastewater produced will be 7.1 mgd.If 50 percent of the reclaimed water is reused, the wastewater to be discharged tostreams will be 3.6 mgd. If Type I reclaimed water is produced, the futurepollutant loading will be less than the current loading.

Vegetated filter strips adjacent to streams can provide significantstormwater treatment as overland flow passes through the filter strips.It is recommended that entities in Caldwell County that have regulatory authorityimplement requirements for filter strips adjacent to streams. The filter stripsshould be on each side of the stream with the width of the filter strip beingmeasured from the top of bank for the stream. The recommended filter stripswidths are presented in Table 14-7.Klotz Associates Project No. 0972.000.000January 201014-20Caldwell County Regional Water and Wastewater Planning StudyFinal Report

Capturingand filtering the “first-flush” runoff can significantly reduce pollutant loads. Inaddition, development rules that encourage limited impervious cover on tractsshould be utilized.It is recommended that entities in Caldwell County (those that have regulatoryauthority) implement requirements for limited impervious cover on tracts andrequirements to capture and filter first flush runoff. The recommended imperviouscover limits and filter requirements are presented in Table 14-8.Table 14-8Impervious Cover FiltrationRequirementsVolume ofImpervious Cover Water to BePercentageFiltered,Inches0 to 20 0.00>20 to 50 0.50>50 to 80 0.75>80 to 100 1.00Klotz Associates Project No. 0972.000.000January 201014-21Caldwell County Regional Water and Wastewater Planning StudyFinal Report
