Curve Lake First Nation (CLFN) is seeking proposals from qualified consultants to provide project engineering services in the development of our Proposed Water Treatment Plant and Water Supply Project. Curve Lake had previously completed a feasibility study in 2010 which had recommended development of a communal water system utilizing groundwater as the source water. However, due to the passage of time and subsequent studies and additional information, there remain questions as to how to best implement a communal water system. The work has been broken out into two stages as outlined in the attached Terms of Reference to Provide Consulting Engineering Services for the Curve Lake First Nation Water Treatment Plant Project. Stage 1 is based on the assumption that the currently identified wells have sufficient water quantity and that the water is of a treatable quality. The purpose of Stage 1 is to review existing documents, update design requirements, and provide a recommended path forward for the water project.
A full outline of the objectives are provided in the attached Consulting Engineering Terms of Reference. The objectives include:
Update Design Requirements
Review the existing reports, studies, reference materials and project background to familiarize himself/herself with the history and intent of the project.
Update the current population and housing numbers, and provide the ten (10) twenty (20) year, and fifty (50) year population if required and housing projections for Curve Lake, with and without the inclusion of cottagers.
The consultant, in conjunction with the project team, shall prepare a list of existing and proposed non-residential development for the 20 year timeframe, and develop projected water needs for these developments.
Update the projected ten (10), twenty (20), and fifty (50) year Maximum Day water demand estimates for Curve Lake, with and without the inclusion of cottagers.
Assess Existing Wells
Having reviewed the existing reports (including the hydrogeological study undertaken by Oakridge Environmental in 2018), the consultant will provided an opinion regarding the ability of the currently identified wells to provide sufficient water quantity. Note that the water source must provide enough quantity for the twenty (20) year growth of the First Nation (including cottagers), and be of suitable quality.
The consultant will also provide an opinion on the need for firm capacity of the wells, and if the currently identified wells can meet this demand.
If the consultant confirms that the capacity of the source and the currently proposed treatment processes (slow-sand with pre-treatment) are still the valid options, the consultant will issue a report documenting this, with an updated Class C total estimated cost including soft costs and the study will be considered concluded. At this point ISC will begin the process to get approvals for design funding.
However, if the consultant finds that the capacity of the sources is now considered deficient, or different treatments are recommended to be considered, the consultant will issue a report stating what capacities are required and what additional treatment options need to be considered.
o If the consultant finds that the currently identified wells cannot meet the identified demands, the consultant will provide an opinion regarding the feasibility of adding additional wells to supplement the currently identified wells.
o Based on the available information the consultant will provide a technical opinion of the need to revisit the feasibility of each source water option identified in the Feasibility Study (ground water, surface water, infiltration gallery, and municipal type agreement).
Stage 2 is to begin only after all the items in Stage 1 have been undertaken and approval to proceed to Stage 2 has been issued to the Consultant by the Project Team. While it is likely that there will be a Stage 2, there is no guarantee that the contract will need to proceed to Stage 2.
As Stage 2 only occurs if the opinion is that the currently identified wells and/or the currently recommended treatment are not sufficient, the purpose of Stage 2 will be to identify a way forward and to provide an updated feasibility study.
The Consultant’s scope of work for Stage 2 is described in general terms below:
Develop Groundwater Capacity
As the project team has seen indications there may be need for additional groundwater capacity to be developed and tested, the proposal for Stage 2 will include an allowance for the following;
o Engage a hydrogeologist to recommend drilling locations for 3 additional wells
o Allowance to drill up to 3 additional wells
o Engage a hydrogeologist to undertake long term pump testing and sampling to find the quality of the up to 3 new wells in addition to the wells identified in the Oakridge study
o Have the hydrogeologist complete aquifer modeling as described in the Hydrogeological scope of work listed in Appendix B
o Provide rehabilitation, retesting and GUDI analysis of Well #10
o Provide Hydraulic Fracturing (assume 4 wells)
o Follow-up well testing of Hydraulic Fractured wells
o Simultaneous Well Testing of wells to confirm capacity
The Consultants Proposal will include cost estimates and schedules for the probable recommended studies and testing that would occur in Stage 2.
Consider Other Source Water Options
As the Stage 2 work would be revising the work done in the 2010 Feasibility Study, ISC has recommended that the consultant also confirm the recommendations surrounding surface water, infiltration gallery, and municipal type agreements.
If necessary, recommend studies or tests that may be conducted to verify the feasibility of each source water option.
Potential options not discussed in the feasibility study should also be considered, if viable.
For options deemed not viable in the previous feasibility study, the consultant can choose to accept those recommendations as still valid.
For options that are technically viable, the consultant shall identify design criteria, construction requirements, estimated construction costs, estimated operations and maintenance costs and produce 20 year life cycle cost estimates.
The consultant shall (or ensure that that others shall) sample and test raw water from the preferred source and alternative sources for physical, chemical, radiological and bacteriological concentrations in order to confidently identify the best water supply source for Curve Lake.
The consultant shall provide recommendations for what additional testing is required to continue between the completion of feasibility and completion of design to provide additional confidence in the recommended water system.
The consultant shall conduct a treatability study to analyze and determine the preferred treatment option for the preferred water supply.
The Consultant shall recommend a treatment process; provide description of the Water Supply System. It shall include a schematic process flow diagram of the complete new water supply system with process units and equipment identified. For the recommended process, describe the required disinfection options. The consultant shall assess various primary and secondary disinfection strategies and recommend to the First Nation the best alternative.
A more detailed description is available in Appendix A (attached): Terms of Reference To Provide Consulting Engineering Services for the Curve Lake First Nation Water Treatment Plant Project.
The Curve Lake First Nation is located on a peninsula situated between Buckhorn Lake, Harrington Narrows and Chemong Lake. The total registered population of Curve Lake First Nation is 2,339. There are approximately 985 members who live on-territory while 1,354 live off-territory. There are approximately 372 member owned residences on-reserve as well as 230 residences on leased cottage lots. There are a number of commercial and institutional buildings including 2 gas stations, Government Services Building, Health Centre, Business Centre, Public Works Garage, Community Centre, Church and Early Learning Centre. Governance is provided by a Council is comprised of an elected Chief and eight (8) Councilors. With the exception of 58 homes connected to the Nishnawbeke Subdivision WTP, the majority of residents are serviced by individual ground water wells although a small number of residents are serviced by lake water.
CLFN operations are currently organized into the following departments: Corporate Services, Health and Family Services, Education, Culture, Lands, Economic Development and Public Works. Curve Lake First Nation employs approximately 80 full time employees and 25 casual, contract and sub-staff.
