Adequately managed decentralized
wastewater systems are a cost
effective and long-term option for
meeting public health and water
quality goals, particularly in less
densely populated areas.
US EPA 1997 Report to Congress
Adequately Managed??
EPA 2003 Voluntary National Guidelines for Management
of Onsite and Clustered (Decentralized) Wastewater
Treatment Systems
Management of decentralized systems is
implementation of a comprehensive, life-cycle
series of elements and activities that address
public education and participation, planning,
performance, site evaluation, design,
construction, operation and maintenance,
residuals management, training and certification/
licensing, inspections/monitoring, corrective
actions, recordkeeping/inventorying/reporting,
and financial assistance and funding.

Treatment Systems
Appendix A - Management Program
Elements Fact Sheets
All are guidance to assist others in
defining a cradle to grave management
system.
We need a program description from the
perspective of the system
For our discussion:
Management of decentralized wastewater
systems is a collection of competencies that
ensures a specific wastewater system is
provided and operated with sufficient
resources to ensure continued compliance.
Leads to standards aqainst which to measure
“adequate”
Competency, Compliance, Collection
Competency
Every person
Owner, site evaluator, designer, regulator,
installer, operator
Every regulation
Every permit
Every piece of equipment or material
Must be competent in his, her, or its role in
affecting the wastewater system
Compliance
Every individual or group action
Every treatment process
Every equipment function
Must achieve or maintain compliance with
public health and environmental goals
Collection (Revenue)
Owner must have or be able to collect
sufficient resources to continually provide
the required actions and functions.
The Achilles heel of adequate management
Whether the system is a simple conventional
system with no moving parts or a complex
advanced treatment/drip system, each of
these three standards must be satisfied to
be considered an effectively managed
system.
Competency Elements
Siting
Competent individuals rather than
prescriptive regs
Planners/zoning staff
Soil scientist
Engineer
Hydrogeologist
AOSE
Competency Elements
Design
Educated, trained, experienced designers
Nuclear engineers should not design
sewage systems
Site specific designs
Regulatory staff should not be designers
Accountability
Competency Elements
Permitting
Performance based regulations
Site specific permits
Minimal BPJ requirements
Competency Elements
Construction
Equipment and material properly
manufactured and compatible with site
and treatment process
Water tight tanks critical to success
Reliable third party performance
certification of complex treatment
systems
Well trained and experienced construction
personnel
Proven construction and installation
methods used
Competency Elements
Operation and Maintenance
O&M level matched to system complexity
Quarterly servicing of suspended growth
systems inadequate
Service providers trained specifically for the
system equipment and processes
Trained and regulated pumper/haulers and
septage disposal sites
Competency Elements
Owners
Competency level matched to level of
responsibility for the system
Individual vs. contractor vs. utility (RME)
Compliance Elements
Legal and policy requirements
BMPs, engineering standards, regulations,
policy requirements
Owner accountability
System owner almost always legally liable for
compliance
Regulators, designers, installers, and service
providers should have to share accountability
Collection Elements ($$$)
Money for O&M required regardless of
system size
Owners of individual onsite systems totally
responsible
Contract O&M providers at owner’ mercy
Utilities that own systems have unique
control over income
EPA’s Management Models
Level 1 – Homeowner Awareness Model
Level 2 – Maintenance Contract Model
Level 3 – Operating Permit Model
Level 4 – Responsible Management Entity O&M Model
Level 5 – Responsible Management Entity Ownership Model
Important distinction between on-site and cluster
Level 1 – Homeowner Awareness Model
Management by individual property owner with
local regulatory oversight
Should be limited to conventional systems
Many Level 1 jurisdictions include back-yard
activated sludge plants
Many areas not within a local regulatory
jurisdiction
Regulatory oversight complaint based
Few documented jurisdictions with adequate
system management by homeowners
Level 2 – Maintenance Contract Model
Service contracts with regulatory oversight
Oversight generally complaint based
Regulatory agencies unable to assign sufficient
resources to police such systems and contracts
Owners unwilling to pay for sufficient level of
O&M for complex systems
Payment provisions of contracts difficult to
enforce
Insufficient management of back-yard
activated sludge plants
Level 3 – Operating Permit Model
Limited term operating permits to owners
Permit renewal based on continued compliance
Regulatory agency oversight and enforcement
Opportunity for performance based permitting
Slow and ineffective legal proceedings
No mechanism to ensure revenue generation
Insufficient management of back-yard
activated sludge plants
Level 4 - Responsible Management Entity
O&M Model
Operating permits issued to RME
Regulatory agency oversight and enforcement
Primary accountability with RME not owner
More incentive on RME to perform
Unless RME is a regulated utility, it has limited
ability to guarantee revenue generation
More likely associated with new, multi-property
wastewater systems
Level 5 – Responsible Management Entity
Ownership Model
RME owns the wastewater system
Direct enforcement link between regulator and
owner/operator
All permits issued to the RME
RME generally required to be Public Utility
Regulation under PSC provides some business
and revenue protection
Ability to force customers to pay for service
Wastewater System/Management Level
Low density conventional systems
Well suited to Level 1 management program
High density conventional systems
Require Level 1, 2, or 3 program with increased
resources
Onsite aerobic systems with or without drip
Require a Level 5 or strong Level 4 (Trapper
Davis)
Level 5 suited to high density
Clustered STEP/STEG, treatment, drip systems
Should be limited to Level 5 public utility RMEs
Ensuring Cradle to Grave Management
Demand competency of all personnel,
functions, and processes through life of
system
Expect compliance with all regulations,
policies, and public heath and
environmental goals
Ensure mechanisms for generating
collection of sufficient revenue to pay for
lifetime O&M and system replacement
But do we have the organizational,
regulatory, and political structures in
place to accomplish?
Will we ever?
