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

Facilities will Rely on Power from Landfill Gas Cogeneration and use of Existing Outfall

Cogeneration power from adjacent landfill New 6 mw cogeneration

plant Initially, energy source:

combination of natural gas and methane

Tie to existing 5 mw cogeneration plant

Renewable energy credits

Long-term, low-cost reliable energy supply

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
