Desal in Monterey
Jim HeitzmanGeneral Manager
Marina Coast Water District
We are building a brackish water desalination plant!
It has broad public support It is built on the California coast It also treats intruded, underground
seawater It solves environmental and
regulatory problems It was formulated in 2008 and is
scheduled to go on line in 2015

It was challenging.Are there any takeaway lessons?
yes
Break with tradition and avoid the comfort of Bureaucracy
11
Sometimes it goes fast and sometimes it don’t
12
Harness the intellect of engineering staff and others
13
Prepare for a long journey
14
Hope for an orderly process15
But be ready for a little chaos once in awhile
16
But there is a path forward... If you keep moving
17
Work to bring diverse groups together
Have your project treated like royalty 19
By not trying to solve all your problems on your own
But by working together
Hold public meetings
Find your seats, please!
Work together
Turns out working together is like a picnic in the park

Monterey Desalination Water ProjectUse brackish groundwater from a seawater barrier
protecting the Salinas Basin, to create potable water for the peninsula
Use vertical and slant wells avoiding open ocean intakes
Discharge brines within Ocean Plan regulations because brackish sources are less salty than straight seawater
Solve the regulatory and hydraulic problems in the Carmel River, Seaside Groundwater Basin, and Salinas Groundwater Basin
Use off-grid power from bio-digested waste from the landfill
26
Project Provides Significant Regional Benefits
Restoration of flows to the Carmel River – Steelhead Fish
Increased reliability Future ability to
address North Monterey County water needs
Reduced wastewater discharge to Marine Sanctuary
Reduced carbon footprint thru green landfill power
Immediate construction to aid economic stimulus
