PROJECT SUMMARY & BACKGROUND The municipal water quality provided in Prince Rupert has known issues in Prince Rupert and although it is generally considered potable (safe for human consumption) it has low PH and high turbidity. Currently Prince Rupert Regional Hospital (PRR) and Acropolis Manor (ACM) are on a local boil water advisory based on the recommendation of environmental health due to the Prince Rupert source water and treatment process that could result in undetected incidents of water borne pathogens in the municipal water supply.
Due to the initial concerns of the water quality within PRR and ACM a comprehensive water quality study was undertaken that resulted in a recommendation that the best alternative to municipality wide treatment is a NH owned and operated source water treatment system for PRR and ACM. The high level solution analysis of the water quality study recommends separate treatment systems for PRR and ACM.
Based on the study recommendations and on the assumption that improved municipal water treatment is at best 5+ years away separate water treatment projects (for PRR and ACM) have been put on the capital projects list based on the high level budgets provided in the study.
The initial recommendation estimated peak demand from monthly consumption and recommended two systems in part due to the two buildings domestic water being provided by two separate services. Northern Health Authority (NHA) recognizes that a single system treating both PRR and ACM may be a more cost effective solution once there is a more detailed design (including spatial requirements and location considerations) and financial analysis incorporating life cycle and operating costs is complete.
In addition to the general water quality, issues of low PH and high turbidity the municipality has enacted boil water advisories (BWA) due to potential of Giardia and/or Cryptosporidium in the past. Currently there is no BWA due to Giardia and/or Cryptosporidium in effect; however, NHA Environmental health department has recommended that both sites (PRR and ACM) maintain the practice of boiling municipality supplied water prior to consumption and/or use-bottled water for consumption. Therefore, NHA is also considering including treatment/processing to ensure municipality supplied water is potable during a Giardia and/or Cryptosporidium caused Boil Water Advisory.
Accordingly, NHA is seeking design and consultant services from a qualified consultant (or consortium) to provide equipment recommendations/specifications, plant spatial layouts, class C capital cost estimates, operating cost estimates and 25 year life cycle costs for the following four solutions:
1) Separate Treatment Plants in PRR and ACM to manage the water quality issues (Low PH and Turbidity) only.
2) Single Treatment Plant in PRR with supply lines to ACM to manage the water quality issues (Low PH and Turbidity) only.
3) Separate Treatment Plants in PRR and ACM to manage the water quality issues (Low PH and Turbidity) and to ensure water is potable during a Giardia and/or Cryptosporidium caused Boil Water Advisory.
4) Single Treatment Plant in PRR with supply lines to ACM to manage the water quality issues (Low PH and Turbidity) only and to ensure water is potable during a Giardia and/or Cryptosporidium caused Boil Water Advisory.
Proposals are to be emailed and submitted in PDF format; to NHA using the following contact information: Phil Beaulieu – Manager, Facility Maintenance, Plant Services Northern Health Authority.
Proposals are to be submitted no later than: Thursday, October 8, 2020 at 2:00pm. NHA is not responsible for misdirected emails; please take measures to confirm receipt by NHA. It is strongly recommended that the party submitting the proposal follows up by phone upon sending the transmission to ensure the submission is received.
