1 Presented to the Connecticut Association of Water Pollution Control Authorities | April 26, 2013 Community Systems 101 Presented by Thom Knowlton, P.E. Senior Water & Wastewater Engineer Milone & MacBroom, Inc.

2 Community Sewerage System is defined in statute to mean “any sewerage system serving two or more residences in separate structures which is not connected to a municipal sewerage system or which is connected to a municipal sewerage system as a distinct and separately managed district or segment of such system” CGS Chapter 103, Section 7-245(3)

3 1. Two or more residence structures: home, condo, apartment, school dormitory, etc. 2. Community sewerage systems often involve large-scale subsurface sewage disposal systems treating wastewater from multiple residences

4 Old Saybrook, Connecticut Eden Harbour Active Adult Condominium Community

5 Type / Size of SystemRegulatory Agency Systems Regulated by the Connecticut Department of Public Health (DPH) Conventional system with design flow less than 2000 gallons per day Local Health Department in the town the site is located Conventional system with design flow greater than 2000 gallons per day but less than 5000 gallons per dayDPH Sewage Program (860) Alternative treatment with design flow less than 5000 gallons per day Systems Regulated by the Department of Energy & Environmental Protection (DEEP) Conventional systems with design flows greater than 5000 gallons per day, including sites where multiple smaller systems on a single “lot” have a combined flow greater than 5000 gallons per day DEEP Subsurface Sewage Disposal Program (860) Community System Any system utilizing alternative treatment, regardless of size

6 Then why should WPCA’s be concerned about Community Sewerage Systems? CGS Chapter 103, Section 7-246(b): The WPCA shall manage or ensure the effective supervision, management, control, operation and maintenance of any community sewerage system or decentralized wastewater management district not owned by a municipality.

7 What other ways do Community Sewerage Systems impact WPCA’s? Planning? Mapping? Construction Inspection? Long-term Oversight? Yes

8 Water Pollution Control Plan CGS Chapter 103, Section 7-246(b): Plan shall include: 1.1.Areas where municipal sewerage facilities are planned and the schedule of design and construction anticipated 2.2.Areas where sewers are to be avoided 3.Areas served by any community sewerage system not owned by the municipality 4.Areas to be served by any proposed community sewerage system not owned by the municipality 5. Areas to be designated as decentralized wastewater management districts

9 Sewer Service Area Map 1.1.Current sewer system layout 2.2.Future sewer system areas 3.3.Areas of subsurface disposal, community systems, and 1. decentralized wastewater management districts 4.4.Areas not to be served by sewer 5.5.In compliance with local and State Plan of Conservation 1. & Development maps 6.6.Compliance with State C&D Plan in order to be eligible for Clean Water Funding on projects over $200,000

Other site specific requirements 2.2.WPCA 1.a. Ensure the effective supervision, management, control, and operation and maintenance of the system 2.b. Operation & Maintenance Agreement

13 Benefits of Community Sewerage Systems 1.1. Systems are designed, permitted, installed, and paid for by someone other than WPCA 2.2. Systems are owned and operated by someone other than WPCA 3.3. Environmental Improvements 4.4.Higher intensity development of land not having sewer access 5.5.Additional revenues if connected to WPCA

15 1.1.“Two or more residences in separate structures” 2.2. The WPCA shall manage or ensure the effective supervision, management, control, operation and maintenance of any community sewerage system or decentralized wastewater management district not owned by a municipality Add them to your Water Pollution Control Plan 4.4. Add them to your Sewer Service Area Maps 5.5.Develop an agreement with property owner(s) 6.6.Get involved early and stay connected
