& KVIS Bob Eichinger April 22, 2015 Decentralized Wastewater
Treatment Systems (DWTS) are also known as Septic Systems, Onsite
Systems, OSWTS, ATU and ETU. A DWTS is any wastewater treatment
system that collects, treats and disperses wastewater close to its
original source. DWTS technologies can be used for residential,
commercial and Small Community (Cluster) systems. DWTS most
commonly do subsurface discharge of treated effluent but they also
do surface discharge. www.alliedcommunity.org

- DWTS & Small Community Systems Brief History in New York
State April 22, 2015 Several hundred Small Community Systems in
USA. Their use is proactively encouraged by the EPA as Green
Infrastructure solutions. DWTS Small Community Systems are eligible
for EPA/CWA funding through EFC same as CTP/Sewer. Low Income
Communities eligible for EFC/DEC Engineering Planning Grants.
Hillsdale, NY completed in 2009 most visible DWTS example in NYS.
DWTS Small Community System RFPs gaining visibility Amenia, Suffolk
County Long Island, Old Saybrook & Old Lyme, CT. NYCDEP CWC has
over 1,000 installed residential & commercial ETUs now looking
at DWTS for Small Community Systems in WOH Watershed. NYCDEP Putnam
County SRP installed 160 residential ETUs to replace failing
residential systems closest to reservoirs from 2004-2011 in Croton
Watershed. Skaneateles Lake EPA National Community Demo Project

& KVIS April 22, 2015 Cost Comparison. The average cost for a
Small Community Cluster System (SCCS) per 3-4 Bedroom Residential
House compared to ETU and Big Pipe Central Sewer Treatment. SCCS =
$15,000.00 per residence. ETU = $21,250.00 per residence. Big Pipe
- Peach Lake = $72,000.00 per residence.
- Slide 17
- DWTS Advantages & Benefits Versus Central treatment Plant
(CTP) April 22, 2015 DWTS usually have a much lower cost for
design, equipment, installation, operation and maintenance versus
CTP. Less disruption to public roads and infrastructure.
Flexibility to replace or upgrade selected properties,
neighborhoods or troubled areas versus CTP all or nothing approach.
Allows for Mix Solution. Allows for managed growth with modular
capacity. Subsurface or surface discharge option with tertiary
treatment (UV, nitrogen & phosphorus reduction etc)
Environmentally beneficial recharge of ground water aquifers and
allows for water reuse opportunities. www.alliedcommunity.org
