Fuss & O’Neill (WPCA’s engineers) calculated: Central Treatment System: $59.1 million for sewers + $12.2 million for the treatment facility = $71.3 million. This does not include the cost of land and operators. Cost per property owner is approx. $28,100. O & M = $500 per year. Decentralized program: $40-45 million. Cost per property owner in WWMD ranges from $0 for those who need no upgrade to $28,100 for those who need ATS (approx. 25% of WWMD). O & M = $200 every 5 years for conventional system, $600 – $800 per year for ATS.
