Bath Road Sewage Lift Station Improvements
Bath Road Sewage Lift Station is located just west of Little Cataraqui River between Bath Road and the Frontenac Mall parking lot, as shown on Figure 1.2. The pumping station receives sewage from the mall and from residential and commercial development north of the Mall and east and west along Bath Road, and conveys it westerly for treatment at Kingston West Water Pollution Control Plant.
Bath Road Sewage Lift Station was constructed in the 1960's and is operating with original equipment and technology. The station is in need of rebuilding, as described below.
Utilities Kingston has retained Totten Sims Hubicki Associates to provide engineering services for a condition assessment, class environmental assessment, detailed design and construction administration for Bath Road Sewage Lift Station. The condition assessment and preliminary design work is now complete. The purpose of this mailing is to advise you of the recommended solution.
A condition assessment of Bath Road Sewage Lift Station has been completed and has observed the following:
- the generator control building is in need of extensive repair to doors, roof and flashings;
- sewage pumps have exceeded their useful life and need to be replaced;
- equipment installations do not meet current electrical safety regulations, particularly with reference to clearances and proper conductor over current protection;
- the diesel generator and transfer switch are very old and indications are, even with good maintenance, the unit cannot be relied on to start when it is needed;
- ventilation systems in the various enclosures are non-standard or non-existing;
- pumping station capacity has been measured at 48 to 49 litres per second (L/s), which exceeds the stations rated capacity of 44 L/s. A firm capacity of 48 L/s or greater is required. (Pre-design has determined that a new firm capacity of 50 L/s is required).
The purpose of this environmental assessment is to plan for improvements to Bath Road Sewage Lift Station to ensure reliable service, to comply with current safety standards, and to meet current and future demands of the existing fully developed service area.
Public and Agency Consultation
A Notice of Study Commencement was advertised in the Kingston Whig Standard and in Kingston This Week with the first insertion on April 11, 2006. Copies of a brochure, similar to this one, were circulated to residents and businesses within 120 m of the Bath Road site. Copies were also forwarded to a long list of interested review agencies.
As a result of the above circulation one request to be added to the mailing list was received from a member of the public and four agencies responded in writing that they have no concerns/objections to the proposed improvement. Utilities' staff also responded to telephone callers requesting additional information
Analysis of Alternative Solutions and Selection of recommmended Solution
An analysis of alternative solutions has been completed and is documented in a Phase 1 and 2 Report. Options including "Do Nothing" and "Rebuild at a Different Location" have been evaluated. Replacement of the existing facility, with higher capacity, on the same site is the recommended solution.
The recommended solution can be further detailed as follows:
- Construct a new, in ground wet well of pre-cast concrete sections. Decommissioned existing pumping station wet well.
- Install two new submersible pumps of 50 L/s capacity to meet current and future needs of the existing service area.
- Provide standby generator capacity of 55 kW, sufficient to operate one pump, heating, ventilation, and controls. Install a new generator in a new 6.0m by 4.2 m control building. Demolish existing 3.8 m by 2.4 m generator building.
- Install new electrical systems with new instrumentation and controls, to current safety standards and with remote monitoring.
The recommended solution includes a listing of commitments that are summarized on the following table:
|Construction Impacts||City noise by-law will be enforced.|
|Blasting for new works will not be allowed.|
|A silt fence will be required adjacent to the road side ditch that outlets to Little Cataraqui Creek.|
|Standard specifications regarding no work in watercourses, refuelling areas remote from watercourses, and reporting of spills will be included in construction documents.|
|Restoration will be completed as quickly as possible.|
|Management of Surplus Materials||Surplus materials generated by construction will be handled in accordance with Ontario Provincial Standard Specification 180.|
|Maintenance of Service||Capacity to pump sewage will be maintained at all times during construction.|
|Noise||Noise suppression will be installed on new generator facilities. MOE Certificate of Approval (Air) will be required.|
|Maintenance of Sewage Collection System||Ongoing maintenance of sewage collections system will be required to ensure that the new pumping capacity is sufficient for all future needs.|
|Agency Approvals||Applications will be made for amendment of MOE Certificates of Approval for pumping station and for standby generator facility.|
Class EA Process
This project is being undertaken in accordance with procedures for a Schedule B project as set out in the Municipal Class Environmental Assessment, June 2000. Schedule "B" projects are those with modest impacts which are approved subject to a defined screening process.
The Class EA process provides for public and review agency input to allow all concerns to be identified and addressed when evaluating solutions. Notice of Completion of this EA has been issued through circulation of this brochure, and through newspaper advertisements. The project file, which consists of the Condition Assessment Report and a Phase 1 and 2 Environmental Assessment Report, is available for review. Comments on the Recommended Solution are invited. If concerns arise regarding the project which cannot be resolved in discussion with Utilities Kingston, a person may request that the Minister of the Environment make an order for the project to comply with Part II of the Environmental Assessment Act (referred to as a Part II Order), which addresses individual environmental assessments. If no concerns are received within 30 days of the issuance of the notice of study completion the project may proceed to construction.
