Sewage Treatment Options Three Approaches to Wastewater Treatment Conducting a Complete Assessment Community Process for Making Wastewater Treatment Decisions
Effective treatment – protect health & environment Affordable life-cycle costs: installation, operation, maintenance, repairs, monitoring, replacement Sustainable – water supply & economics Esthetically acceptable Reliable Manageable Adequate space Flexible – flow & waste strength Consistent with community values & culture Consistent with land use plan Fits a long range plan Community solution criteria
1) Centralized: Collection network (many homes) Central treatment facility(ies) Discharge - surface 2) Decentralized: Individual or small group of homes On-site treatment facilities (near site) Discharge - subsurface 3) Combination Three approaches to wastewater treatment -
Typical Cost Range per Connection in Low Density Areas • Design & Installation: • Decentralized - $6000 to $15,000 • Centralized - $13,000 to $40,000+
Anatomy of a Septic System • Plumbing: wastewater collection • Septic tank: primary treatment • Soil treatment system: final treatment/dispersal Homeowner Education
EPA: “Decentralized approach will work” • 1997 - EPA suggested ‘decentralized’ systems as a solution to many sewage treatment problems • Why? • Now have good on-site treatment systems • Cost is usually lower than centralized • Report: • www.epa.gov/ow-owm.html/decent/index
Decentralized systems: • Individual or multi-household (cluster) • Standard - trenches, mounds, at-grades • Alternative Systems- • pre-treatment • final treatment/dispersal • separation • Water supply options
Typical assessment: Compliant & Non-compliant More complete assessment: Compliant & ‘Could be’ Compliant & ‘Can’t be’ Compliant Determining ‘decentralized’ feasibility

Small Community: • Communities not currently served by centralized systems - “unsewered” • Include: • incorporated • unincorporated • villages • shore lands • ‘groups of homes’
What might be ‘unique’ about these small communities? • Small lots • Low overall density (perimeter of a lake) • Poor Soils • Especially valuable natural resource (I.e. lake, river) • Mix of seasonal & full-time residents • Growing or decreasing population • Income levels
How is wastewater currently being handled in ‘unsewered’ areas? • On-site Disposal - • pipe to ditch/lake • non-compliant system • other? • On-site Treatment - • compliant system
Characteristics of Successful Communities • Understand current situation clearlybefore looking at possible solutions • Use the ‘civic engagement’ model to involve diverse interests/views from the community • Have or develop effective leadership from within the community
Characteristics continued • Recognize the bias’s and self-interests of professionals they’re working with • Defines an appropriate goal and boundaries • Identify and examine all options • Keep all affected parties informed
Success or failure? Success or failure in finding a viable solution is frequently more dependent on a sound community process than on the availability of treatment options and financing!
Exploring Small Community Wastewater Treatment • Treatment Options • Management • Community Structures • Costs & Financing
Form a Task Force • Wide range of interests • Citizens and local leaders • Provides leadership for process • Oversees the process (i.e. gathers information, point of contact) • Shares information with stakeholders (especially residents)
Develop a Community Vision for Treatment • Socially acceptable • Cost effective • Provides viable treatment option(s)
The Community Process Finding a Viable Solution That provides: • Effective treatment - protects human & environmental health • Reasonable cost - Life cycle costs = capital costs & O & M • Remember homeowners need to move from costs of occasional tank pumping to regular maintenance costs. • Socially acceptable - community values, culture, esthetics • Is well managed.
Managing Small Community Wastewater Involves • Education • Process for community to select options • Treatment Options • Management of Systems • Community Structures • Costs & Financing • Working with Professionals • Community Process
Citizens of communities that succeed … • Clearly understand their current situation before they start looking for solutions • Know that only they can make the best decisions for their community • Take responsibility for and ownership of the problem • Have or develop members with strong leadership abilities • Have a clearly defined vision and mission, and set appropriate goals
Citizens of communities that succeed … • Take the time and energy to identify and examine all options before making decisions • Gather information from as many sources as possible before taking action • Keep all affected parties involved and informed all along the way • Identify criteria for making decisions and use all identified criteria.
Communities do not succeed … • When a small group makes the decisions and expects everyone to agree – and pay the bill • When the community lets engineers, consultants or funding sources dictate their choices • Result in chaos, bickering among neighbors, elected officials getting “un-elected,” and a loss of sense of community.
A community ‘vision’ or plan Civic engagement – Responsibility Ownership Setting the appropriate goals: Treatment Affordable Community values/ character Effective leadership Understanding that all professionals have biases & self interests Identify & evaluate all options Involve all interests at the table Keep everyone informed. Keys to Success Remember: This is a LOCAL project not the funders not the consultants not the engineers It belongs to the residents
Message from all of this • Heading towards everyone having a properly operating system and improved management at an affordable cost (ISTS/community) • Goal: protect human health and environment
