  1. Public Hearing - April 28, 2009Lunenburg Comprehensive Wastewater Management Plan

  2. Presentation Team • Kevin M. Olson, PE – Project Manager • Jason D. Jancaitis, PE – Project Engineer Lunenburg CWMP

  3. Lunenburg’s Reasons for Wastewater Planning • Identify and evaluate areas that may not support individualon-site wastewater systems • Population growth concerns • Secondary growth concerns • Limited capacity at neighboring municipal facilities – Fitchburg and Leominster Lunenburg CWMP

  4. CWMP Phases • Project Management and Public Involvement • Phase I – Existing Conditions and Needs Assessment • Phase II – Alternatives Identification and Screening • Phase III – Detailed Evaluation of Alternatives and Draft Recommended Plan • Phase IV – Recommended Plan Lunenburg CWMP

  5. Phase I CWMP • Existing conditions • Water demand/supply sources • Water balance • Wastewater needs assessment • Report and public meeting • May 17, 2007 public meeting Lunenburg CWMP

  6. How is Lunenburg’s Wastewater Treated and Disposed of Currently? Village at Flat Hills • On-site – Individual & I/A Systems • 57 gpd/bedroom • 93 percent of Town • Private Satellite Facilities • Village at Flat Hills – Bioclere System • Permitted flow - 14,850 gpd • Woodlands Village – RUCK System • Permitted flow - 12,500 gpd • Regional Sewer System • Leominster WWTF, IMA - 500,000 gpd • Remaining Capacity - 147,500 gpd • Fitchburg (East) WWTF, IMA - 80,000 gpd Woodlands Village Lunenburg CWMP

  7. Wastewater Needs Assessment • Which areas are on-site wastewater systems adequate for: • Sanitation? • Environmental protection? and • Growth management? • Which areas may “need”: • enhanced on-site solutions? • off-site solutions? or • a combination of solutions? Lunenburg CWMP

  8. Needs Assessment • Five Categories of “Need” • Avoid public health problems • Water supply protection • Protect surface waters • Preserve community character • Support managed growth Lunenburg CWMP

  9. Needs Assessment Methodology • Town-wide Approach • Study Areas Developed • Tier 1 • MassGIS • Data based approach • Ranking formula • Tier 2 • Observation approach Lunenburg CWMP

  10. Areas removed from analysis Previously sewered Cemeteries Protected open space Areas determined by: Watershed Sub-Basins Zoning Lot size Geographic features StudyAreas– 24Total Lunenburg CWMP

  11. Tier 1 Analysis • Utilized a “layered” approach • 12 Layers developed • Depth to bedrock • Soils drainage characteristics • Lot size • Depth to groundwater table • Numerous data sources used • Board of Health database • MassGIS • Soil conservation service Lunenburg CWMP

  12. Phase I CWMP Results Areas with a Need for Further Study • 11 Needs Areas (of the 24 total study areas) • 9 Study Areas • 2 Growth Management Districts • Phase II - Alternatives Identification and Screening Lunenburg CWMP

  13. Phase II CWMP • Identify and Evaluate Alternatives for: • Collection Systems • Treatment Systems • Treated Effluent Disposal Systems • Review Criteria • Technical • Environmental • Institutional • Economics/Cost Lunenburg CWMP

  14. Types of Collection Systems • Conventional System • Gravity service • Common pump stations • Force mains • Low Pressure System • Individual grinder pumps • Shallow installation • Private property work Lunenburg CWMP

  15. Types of Wastewater Treatment Systems Fitchburg East WWTF • Centralized Systems • Publicly owned and operated • Decentralized Systems • Individual on-site • Cluster • Satellite • Typically Privately owned/operated Leominster WWTF Lunenburg CWMP

  16. Treated Effluent Disposal Alternatives Alternatives • Rapid Infiltration • Subsurface Leaching • Water Reuse Village at Flat Hills Lunenburg CWMP

  17. Phase II CWMP Results Shortlisted Alternatives for Detailed Evaluation • Collection Systems • Conventional • Low pressure • Treatment Systems • Regional – Fitchburg, Leominster and Shirley/Devens • Decentralized – Hickory Hills Lake and Lake Shirley • Treated Effluent Disposal • Subsurface leaching Lunenburg CWMP

  18. Phase III CWMP • Evaluated Shortlisted Alternatives from Phase II • Draft Recommended Wastewater Management Plan • Submitted to Town, DEP and MEPA (Spring 2008) • Received Feedback Lunenburg CWMP

  19. Phase IV CWMP • Draft and Final Recommended Plan • Revised Draft Recommended Wastewater Management Plan based on Phase III Feedback and Public Workshops • Submitted to Town - March, 2009 • Final Recommended Plan based on Town and Public Feedback Lunenburg CWMP

  20. Revised Needs Areas • Needs Areas were refined throughout CWMP process • 10 Areas Total • 9 Needs Areas • 2 of 9 Needs Areas Designated for Further Study • 1 Growth Management District – Pioneer Drive Area • Areas Categorized as Primary and Secondary Lunenburg CWMP

  21. Areas 4 & 6 • Area 4 - Lower Mass Avenue • High groundwater • Ledge outcroppings • Small lots • Area 6 - Baker Station • High groundwater • Poorly draining soils • Portions with small lots Lunenburg CWMP

  22. Area 9 • Study Area 9 - Lake Whalom • Lot size – varied • High groundwater • Poor draining soils Lunenburg CWMP

  23. Areas 10L, 10F, 12 & 15 • Area 10L/F - Mass Ave./Beal St. • Small lots • Varied soils • Area 12 - Highland Street • Varied soils • High groundwater/wetlands • Area 15 – Rolling Acres Road • High groundwater/wetlands • Small lots Lunenburg CWMP

  24. Area 14 • Area 14 - Hickory Hills Lake • Small lots • Varied soils • High groundwater • Protect surface water quality Lunenburg CWMP

  25. Area 19 • Study Area 19 - Lake Shirley • Lot size – varied • Soils – fast perc rates • High groundwater • Protect surface water quality • Protect drinking water quality (private wells) Lunenburg CWMP

  26. Area 25– Growth Management District • Area 25 - Pioneer Drive • Leominster-Shirley Road • Commercial/Industrial Lunenburg CWMP

  27. Recommendations • Wastewater Management Techniques • Regional Solution - Leominster • Regional Solution - Fitchburg • Areas for Further Study • Hickory Hills Lake • Lake Shirley Lunenburg CWMP

  28. Wastewater Management Techniques • Septage Management Plan • Recommended for Board of Health • Most parcels to continue use of on-site systems • Manage on-site systems town-wide • Long term sustainability • Sewer Service Area Definition • Sewer Commission has developed a Sewer Bylaw • Comprised of existing sewered areas and proposed new “Sewer Service Zones” • Sewer Service Zone = Study/Needs Area Lunenburg CWMP
