Eliminating Sanitary Sewer Overflows in New England
Eliminating Sanitary Sewer Overflows in Rhode Island: Assistance
Smoke coming from a gutter downspout, taken during sewage system smoke testing, shows a common source of rainwater inflow into a town sewage system. I/I (Inflow and Infiltration) is essentially clean water that takes up collection and treatment system capacity, causing sewer overflows into streets and waterways, sewer backups in homes, and unnecessary costs for treatment of the water. (Source: EPA Region 1)
In our effort to address Sanitary Sewer Overflows (SSOs) in Rhode Island, EPA is using an integrated approach that combines a strong technical assistance program with traditional enforcement actions under the Clean Water Act. EPA and its partners are offering a variety of activities and resources to help municipalities identify and prevent problems with the operation and maintenance of their wastewater collection systems and develop plans for long-term infrastructure management.
Services available from EPA regional technical staff include workshops and other training events, on-site assistance, telephone consultations and the development of useful tools and information.

Workshops and Other Events
Asset Management Committee for Wastewater Systems in Rhode Island
In response to the increasing need for local governments and public utilities to incorporate Asset Management practices within their main business functions, the Narragansett Water Pollution Control Association has formalized an Asset Management Committee to facilitate member education on Asset Management. The program, assisted by EPA-New England Region I and the RI DEM, meets monthly for two hours at wastewater facilities around the state. Contact Joe LaPlante (jlaplante@narrabay.com or at 401-461-8848, ext.213).
Asset Management Software
Asset Management is helpful in determining system condition and assessing the risk/urgency of system repair and maintenance. Two free EPA-sponsored software programs are available to assist with electronic asset management. Hands-on demonstrations of these programs can be arranged for interested wastewater operator groups. Contact Gina Snyder or Jack Healey at EPA for more information.
ENERGY STAR Benchmarking for Wastewater Treatment Facilities in Rhode Island
Training has been provided to many wastewater treatment plants in Rhode Island on how to enter and interpret results of energy use information with the EnergySTAR benchmarking tool. Participants learned how to use the tool to track energy use and impacts, calculate the carbon footprint, and understand what the benchmark means in terms of improvements on the baseline score. The tool uses facility information such as Average Influent Flow, Design Flow (MGD), Influent and Effluent Biochemical Oxygen Demand (BOD) Concentrations, and all sorts of energy use at the facility. To learn more about the ENERGY STAR wastewater benchmarking tool, contact Jason Turgeon (turgeon.jason@epa.gov or (617) 918-1637).
Innovative Energy Approaches for Rhode Island Wastewater Systems
The Narragansett Bay Commission (NBC), with funding for a State Innovation Grant (Sustainable Energy Management Practices for Wastewater Treatment) is working with the Rhode Island Department of Environmental Management and the University of Rhode Island on two projects:
Energy Focused Environmental Management Systems
NBC and its partners will develop an energy management program to reduce energy use and improve energy efficiency at Rhode Island Waste Water Treatment Facilities. The project is using energy audits, a series of trainings and roundtable meetings, EPA's benchmarking tools, and the plan-do-check-act approach to continuous process improvement as described in the EPA's Ensuring a Sustainable Future: An Energy Management Guidebook for Wastewater and Water Utilities (PDF) (113 pp, 1.9MB)Fats, Oil and Grease as a Potential Renewable Resource
NBC will institute an Environmental Results Program (ERP) for the restaurants in its service area through its discharge pre-treatment permitting program. The ERP program will help these businesses improve oil/grease discharge compliance and create incentives to encourage the use of collected used oils and grease as a renewable energy source.

Assistance to Facilities
EPA regional technical staff is available to help individual Rhode Island communities, upon request, on a wide range of topics, including:
- CMOM Assessment Checklist
- Preventive and reactive maintenance and other elements of a comprehensive CMOM program
- Asset management and the TEAMS software program
- Geographic Information Systems (GIS) and mapping
- Energy usage and efficiency
Assistance can be provided via telephone, e-mail, or through an on-site visit. We’re also available to meet with municipal officials to discuss maintenance and other collection system infrastructure issues.
Tools and Resources
Wastewater Collection System Capacity, Management,
Operations and Maintenance (CMOM) Self-Assessment
Checklist, June 2007
This checklist was developed by EPA New England as a revision to Chapter 3 of
the U.S. EPA Guide for Evaluating CMOM Programs at Sanitary Sewer Collection
Systems. Completion of the checklist, as part of each system’s assessment
of the adequacy of its collection system maintenance activities, is a requirement
for the recipients of the Administrative Orders sent as part of this Rhode Island
effort. If you would like a copy of the EPA New England Checklist, please
contact Jack Healey or Gina Snyder as noted above.

Template for Developing Sewer Collection System Preventive Maintenance and Sewer Overflow Response Plans, U.S. Environmental Protection Agency, Region 1 (MS Word) (114 pp, 4.3MB)
A good preventive maintenance program is key to keeping a wastewater collection system in good repair. It helps preserve capital investment while preventing service interruptions and the excessive infiltration/inflow (I/I) and system failures that can result in Sanitary Sewer Overflows (SSOs). The EPA Region 1 assistance office has drafted a Preventive Maintenance and Sewer Overflow Response Plan Template for collection systems to use in developing their own preventive maintenance plans. It is designed to help communities document knowledge as well as better understand their collection system. And by knowing the condition and critical areas of their collection system, a community can improve operations and implement preventive maintenance practices to help reduce or eliminate Sanitary Sewer Overflows (SSOs). As a template document, this must be customized to fit any particular system.
