NPCA-2020-014 - Engineering Design Services Binbrook CA Potable Water Treatment System Upgrade

Invitation to Proponents

This Request for Proposal (the “RFP”) is an invitation by Niagara Peninsula Conservation Authority to qualified engineering firms to submit a proposal to provide engineering design services for a new Potable Water Treatment System Upgrade at the Binbrook Conservation Area as further described in (Appendix D - the RFP Particulars).

The site is presently serviced by an existing, on-site water treatment and distribution systems. The on-site water system provides potable water to the splash pad (reconstructed in 2017), picnic pavilions, the boathouse, a single detached washroom facility, and a faucet at the beach.

The water treatment system obtains raw water from a single well located in the south-central end of the site. The water treatment building that houses the water treatment equipment sits right above the groundwater well. The water treatment system is provided with a flow restrictor to limit the flow to a maximum rate of 43,610 L/d (approx. 8.0 USGPM). The recommended maximum pumping rate of the well is 12.0 USGPM.
The existing water system was reconstructed in the early 2000’s and was designed to meet the attendance needs at that time. Since then, the Binbrook Conservation Area has evolved as one of the leading recreational properties in the Greater Toronto, Hamilton and Niagara area and attendance has increased dramatically. On long weekends and at high attendance events, it is not unusual for the park to run out of water. Currently, the NPCA utilizes water trucks to meet the demands of increased visitation however delivery can be problematic over the summer long weekends.

To address this issue, in 2016 the NPCA commissioned ASI Water to undertake a Water Servicing Audit and Gap Analysis to provide a description of the existing water system, document existing operations and maintenance procedures, and provide recommendations on how to meet future demand flows. A copy of this report is provided as part of this package. During their Gap Analysis, ASI assumed a Maximum Daily Flow requirement of 26,120 L/d (4.8 USGPM). Since this time, the NPCA’s strategy for the park has evolved to the point where the proposed Maximum Daily Flow rate is anticipated to be 43,610 L/d (approx. 8.0 USGPM).
