Executive Summary <br />Wastewater Capacity Charges Study <br />Wastewater capacity charges based on the City's current and recommended unit costs of capacity are <br />shown in the table below. Flow and BOD/SS strength from residential connections is considered uniform <br />among all connections in two categories - Single Family and Multiple Family. Current Flow assignments <br />for each category are changed to reflect reduction in indoor water use. Current BOD/SS strength <br />assignments for each category are increased in inverse proportion to indoor water use so that there is no <br />change in the mass of BOD/SS discharge to the sewer. Flow and BOD/SS strength from individual <br />nonresidential connections vary among a wide range. Flows shown for nonresidential connections are <br />provided only to facilitate comparison of capacity charges for different nonresidential loadings. <br />ES -2 <br />I IHP1'I VIs" c4 nlu n1, cin this -h el 'i "IIhju l Nj; l hc I11111G9lIons LIcuff ,I al the c nd c4 his flc AIII =,�i^dt <br />(gal./day) <br />Flow <br />(milligrams/liter) <br />BOD SS <br />Current <br />FY20 <br />Difference <br />Dollars Percent <br />Unit Costs of Capacity <br />Flow, $/gallons per day <br />$20.51 <br />$22.02 <br />$1.51 <br />7.4% <br />BOD, $/pounds per day <br />$838.61 <br />$938.00 <br />$99.39 <br />11.9% <br />SS, $/pounds per day <br />$961.17 <br />$993.00 <br />$31.83 <br />3.3% <br />Residential Capacity Charges <br />Single Family current> <br />189 <br />195 <br />195 <br />$4,389 <br />$3,920 <br />-$469 <br />-10.7% <br />FY20> <br />145 <br />300 <br />320 <br />Multiple Family current> <br />158 <br />193 <br />193 <br />$3,664 <br />$3,270 <br />-$394 <br />-10.8% <br />FY20> <br />121 <br />300 <br />320 <br />Nonresidential Capacity Charges <br />High Strength <br />3,000 <br />1,000 <br />600 <br />$96,940 <br />$104,440 <br />$7,500 <br />7.7% <br />Medium Strength <br />3,000 <br />500 <br />600 <br />$86,450 <br />$92,700 <br />$6,250 <br />7.2% <br />Low Strength <br />145 <br />300 <br />320 <br />$3,650 <br />$3,920 <br />$270 <br />7.4% <br />ES -2 <br />I IHP1'I VIs" c4 nlu n1, cin this -h el 'i "IIhju l Nj; l hc I11111G9lIons LIcuff ,I al the c nd c4 his flc AIII =,�i^dt <br />
