Title
Continued discussion of Draft Reverse Osmosis Preliminary Engineering Report and Water Rate Study; Formation of subcommittee.
Previous Board Action:
The Infrastructure Board first heard this item on August 31, 2020.
Summary:
Some members of the Infrastructure board have requested the ability to study the matter further as a subcommittee. There is no issue with forming the committee, but it needs to be formalized in a public meeting. The board would need to take an action to form a subcommittee, name members and schedule meetings. All meetings of 2 or more meetings would need to be publicly noticed, and we are able to facilitate them through ZOOM. All attachments to this item are the most recent copies of the reports the board has reviewed.
Previous Summary:
If the Town wishes to continue with potable water production, a new Reverse Osmosis (RO) treatment plant is recommended to reduce chloride and TDS concentrations and to address ongoing operational, maintenance and safety concerns at the water treatment plant (WTP). Two reports are provided as attachments; each with executive summaries of their own, but should be considered together for purposes of discussion of future direction of the system.
Besides developing preliminary engineering requirements for the proposed RO WTP systems, the PER was developed to provide the Town with capital and operations & maintenance (O&M) costs for the proposed WTP. Also, a potential phased implementation plan was developed that focuses on using the existing WTP infrastructure to the extent possible to reduce initial capital costs. In addition, the phased approach implements new treatment processes and modifications, only as needed, to address chloride and TDS levels projected to increase over time
In conjunction, with the proposed costs of conversion to RO a water r...
