<strong>Hilliard</strong> <strong>Sustainability</strong> <strong>Plan</strong>for the transportation costs <strong>of</strong> hauling waste farther distances. As municipalgovernments adjust to reduced revenues from local taxes and the state’sLocal Government Fund, diversifying waste disposal methods represents anopportunity to manage rising costs.MeasureOn July 1, 2010, Rumpke began providing curbside residential solid waste,yard waste, and recycling services to <strong>Hilliard</strong> residents. 14 This contract doesnot cover the disposal <strong>of</strong> household hazardous wastes, scrap tires, bulk materials,or construction and demolition debris, nor does it serve commercialand industrial facilities. 15 Individuals are personally responsible for movingor contracting the disposal <strong>of</strong> these items at appropriate waste facilities.Monthly and annual measures <strong>of</strong> waste can be used to determine howmuch waste is being generated by the residential community, how much isbeing generated per resident, and what percentage <strong>of</strong> total waste is beingrecycled. <strong>The</strong> annual tonnage can be divided by 28,435, <strong>Hilliard</strong>’s populationin 2010 according to the U.S. Census. 16 This data can then be used to trackand promote efforts to decrease per capita waste and increase per capitarecycling. Subsequent population estimates and calculations from the U.S.Census and the Mid-Ohio Regional <strong>Plan</strong>ning Commission should be used tokeep per capita data accurate. 17DescriptionRumpke creates and manages the data associated with <strong>Hilliard</strong>’s solid wasteand recycling, and this data is reported to the Ohio Environmental ProtectionAgency and used in Re-TRAC waste reports. This data is free and availableto the city through registration at the EPA WasteWise Re-TRAC website.18<strong>The</strong> city <strong>of</strong> <strong>Hilliard</strong> generated a total <strong>of</strong> 11,787 tons <strong>of</strong> residential and commercialwaste in 2011. 19 Converting that to a more standard measure <strong>of</strong>Pounds-Per-Person-Per-Day (ppppd), the measure comes out to2.66. Of that total waste, 2,045.8 tons entered the Rumpke recyclingprogram, which equates to 0.39 ppppd <strong>of</strong> recycled material. <strong>Hilliard</strong>’sresidential yard waste constituted the remaining 2,445.1 tons <strong>of</strong> the2011 annual collection, showing 0.47 ppppd <strong>of</strong> yard waste.Per capita water useBackground<strong>The</strong> economics <strong>of</strong> water are apparent in <strong>Hilliard</strong> and all <strong>of</strong> CentralOhio, as the <strong>City</strong> <strong>of</strong> Columbus controls the water supply in theregion. In this case, water reduction on a citywide scale for <strong>Hilliard</strong>can be viewed as an economic benefit for businesses, residents, andthe <strong>City</strong> itself. According to the 2011 <strong>City</strong> <strong>of</strong> Columbus Average BillChart for water use, a single family home with two adults and twochildren will use 3,200 to 4,000 cubic feet <strong>of</strong> water and pay $300 to$364 every 90 days. <strong>The</strong> rates for commercial water use are higherthan those for residents. 20Measure<strong>The</strong> best measure at this time is water usagedata obtained from the <strong>City</strong> <strong>of</strong> ColumbusDepartment <strong>of</strong> Public Utilities (CDPU).<strong>Hilliard</strong> is not master metered meaningthat the <strong>City</strong> itself does not manage water.Because <strong>of</strong> this, the CDPU is the only sourcefor data. 21 This data should be secured andkept on file by the city <strong>of</strong> <strong>Hilliard</strong> in spreadsheetform and given to the <strong>Sustainability</strong>Commission. Using Micros<strong>of</strong>t Excel, CDPUdata can be easily used to calculate annualaverage use and costs for residents, busi-ECON.

<strong>Hilliard</strong> <strong>Sustainability</strong> <strong>Plan</strong>ECON. EXECUTIVEENERGY DEV. &SOCIAL SUMMARY WASTE EQ.REDUCTIONnesses, and other water users in <strong>Hilliard</strong>. This calculation should beperformed annually.When this data is calculated it will also be important to display itin a way that makes sense to the public. One CCF accounts for onehundred cubic feet <strong>of</strong> water. This equates to a total <strong>of</strong> 748 gallons<strong>of</strong> water or a square pool that is five feet wide on all sides and fourfeet deep. <strong>The</strong> annual data from the CDPU can easily be convertedto gallons using the conversion <strong>of</strong> One CCF to 748 gallons <strong>of</strong> water(X CCF *748 = y gal). 22Another analysis should consider the economic impact <strong>of</strong> waterusage in <strong>Hilliard</strong>. Such a study can be done by taking the currentprice <strong>of</strong> water in <strong>Hilliard</strong> in CCFs from CDPU and multiplying it bythe amount <strong>of</strong> water in CCFs that was actually used (X CCF * $ perCCF = Total Cost). This calculation will show the price tag <strong>of</strong> waterusage at this scale. More detailed information would be needed todetermine individual usage. This could be gathered by a residentsurvey, which would be used as a sample, or the <strong>City</strong> could try andrequest more detailed records <strong>of</strong> <strong>Hilliard</strong>’s water usage from CDPU.Currently the only data available is annual usage data.Description<strong>The</strong> combined cost <strong>of</strong> water to residents in <strong>Hilliard</strong> is approximately$2,628,804.76 to $3,002,547.80 per month between theyears <strong>of</strong> 2010 and 2011. 23,24,25 This price was calculated by usingdata obtained from CDPU multiplied by information obtained andcalculated from the <strong>City</strong> <strong>of</strong> Columbus. <strong>Hilliard</strong> has a total wateruse <strong>of</strong> 775,601.63 CCF, or 580,150,017.00 gallons, <strong>of</strong> water used byresidential-type service code in 2011. 26 <strong>Hilliard</strong> residents use anaverage <strong>of</strong> 6.82 CCF, or 5,100.00 gallons, <strong>of</strong> water per month. 27 Thisamount presents the opportunity to decrease water use by residents, thuslowering bills.<strong>The</strong> <strong>City</strong> <strong>of</strong> Columbus’s 2011 Average Bill Chart shows an average usage <strong>of</strong>8-10 CCF per person every 90 days. This can be compared to data that wasobtained from the CDPU Water Distribution and Engineering Division <strong>of</strong>Power and Water. This data shows annual water usage in CCF in nine servicecodes. In 2011 the city <strong>of</strong> <strong>Hilliard</strong> consumed a total <strong>of</strong> 1,218,725.93 CCF <strong>of</strong>water. In 2011 <strong>Hilliard</strong> consumed 1,090,063.83 CCF. This quantity shows a10.56% net reduction <strong>of</strong> water usage from 2010 to 2011. Between these twoyears consumers with a residential-type service class code used a two-yearaverage <strong>of</strong> 66% <strong>of</strong> the total water. This was followed by the commercialservice code using an average <strong>of</strong> 21%. Interestingly the other seven servicecode classes all used less than 2% <strong>of</strong> the total water usage. 28 See EWR AppendixCalculation Sheet 1.In 2011, <strong>Hilliard</strong> used a total <strong>of</strong> 815,367,741.85 gallons <strong>of</strong> water across allservice codes. A total <strong>of</strong> 518,903,004.01 gallons <strong>of</strong> water was used in residentialservice class codes. 29 This data can easily be compared to the 2010census figure <strong>of</strong> 28,435 <strong>Hilliard</strong> residents; 30 there would be an aggregatewater usage <strong>of</strong> 2.27 CCF per person per month. 31 This is only slightly differentfrom the <strong>City</strong> <strong>of</strong> Columbus’s estimate <strong>of</strong> 8-10 CCF per 90 days, or approximately2.6-3 CCF per month. 32 See EWR Appendix Calculation Sheet 2.This means that the average resident <strong>of</strong> <strong>Hilliard</strong> uses a total <strong>of</strong> 20,402.67gallons <strong>of</strong> water per year or an average <strong>of</strong> 1,700.22 gallons each month. Applyingall <strong>of</strong> this to cost, each resident <strong>of</strong> <strong>Hilliard</strong> must pay between $92.45and $105.59 per month, 33,34 which would account for a range between$2,628,804.76 and $3,002,547.80 per month spent by all residents <strong>of</strong> <strong>Hilliard</strong>on water. 35 <strong>The</strong>se types <strong>of</strong> calculations can be a good way to gauge and displaywater usage trends in <strong>Hilliard</strong>.
