He presented installation costs ranging from $9,000-$75,000 for individual 4- <br /> bedroom homes and $20,000460,000 per lot for community systems. He emphasized the wide <br /> ranges reflect custom designs, site conditions, material choices, and contractor pricing variations. <br /> He noted potential economies of scale with community systems, though site-specific factors can <br /> counterbalance savings. Tony Whitaker noted that individual homes with advanced treatment face <br /> disproportionate testing costs compared to community systems, where costs are distributed <br /> among multiple owners. <br /> Slide #14 <br /> NC DHHS Onsite Wastewater System Types <br /> OrangeInspection Inspection <br /> System Example Frequency-By Frequency-By <br /> Classification Characteristics Management Entity Mgmt.Entity County <br /> Type Composting Toilet Owner None None <br /> x Single family with d <br /> CU a Type II conventional dispersal Owner None None Q) <br /> oSome types of non- rr <br /> u Type III conventional dispersal Owner 5 years if a pump 5 years if a pump � <br /> 00 _ <br /> r bb <br /> LPP dispersal,shared Certified Operator or Annually or Semi- 0 <br /> M Type IV 5 or 3 years <br /> C elements,etc. Public Mgmt.Entity annually IMP <br /> DSE>3000 I gpd,AP< Certified Operator or I e Type V 3000 gpd,etc. Public Mgmt.Entity Annually-Weekly Annually — <br /> Certified Operator or I <br /> LTypeVl —AP>3000gpd — Monthly-Daily —Semi-annually <br /> Public Mgmt.Entity <br /> Any Community System will be classified as Type IV,V or VI. <br />
