The Cambria Community Services District will present an update on water supply options it and the Army Corps of Engineers are working on and take public comment at a workshop meeting Thursday.

CCSD staffers and members of the Corps engineering team “will review the various water supply concepts being developed, as well as evaluation criteria that the engineers are currently developing,” according to Bob Gresens, district engineer.

The Army Corps, in cooperation with the district, is working on developing a project to ensure a reliable water supply for Cambria.

Alternatives include seawater desalination, local and imported surface water, groundwater, hard rock drilling and seasonal reservoir storage.

Conservation and recycling have also been studied by the district, and some programs implemented, as part of Cambria’s overall water supply package.

The Corps is currently working on environmental reports on water supply alternatives. In February, the Corps said it expected to release a draft of that document in September.

The upcoming meeting is complementary to but not directly part of that environmental review process.

The meeting will include discussion of criteria used to choose between projects, including upfront capital costs and ongoing operational costs.

Another workshop is scheduled for July 19. The purpose of that meeting will be to rank the projects, using criteria shaped in part by Thursday’s meeting.

Discussions at both meetings will focus on engineering aspects of potential projects, Gresens said; environmental evaluations will be part of the ongoing environmental study and incorporated into the eventual report.

This week’s meeting begins at 1 p.m. Thursday at the Veterans Memorial Building, 1000 Main St. It’s expected to last two to three hours.
