<br /> Table 14 summarizes the data tabulated in Tables 11-13. Based upon the above data set,on average, Orenco Effluent Sewers have construction
<br /> costs that are 41% less than gravity sewers.
<br /> Table 14.Constructed Collection System Costs:*Three Collection System Technologies(USD 2014).
<br /> Type Average Median Minimum Maximum
<br /> STEP $9,702 $9,283 $6,666 $15,687
<br /> Gravity $16,394 $15,304 $10,247 $25,112
<br /> Grinder $11,468 $11,258 $6,488 $15,693
<br /> USD 2014 costs adjusted per ENRCCI.
<br /> Note that STEP systems integrate primary treatment into the collection system,thereby eliminating influent screening, primary clarification, and
<br /> other primary treatment processes common in secondary wastewater treatment facilities. Pressure sewers(STEP and grinder)are low pressure
<br /> and watertight,therefore nearly eliminating 1/1,which enables smaller secondary and advanced treatment processes.
<br /> Phasing Considerations
<br /> Developments or communities that anticipate slow growth are often well suited for Orenco Effluent Sewers.The front-end infrastructure (main-
<br /> lines) represent less than 20%of the overall cost of the collection system; the majority of the costs (on-lot equipment) are deferred until the home
<br /> is constructed or connected,and they are generally financed with the home.
