D. GENERAL BUSINESS
Todd Reynolds, Kennedy/Jenks Engineers will make a presentation to the board on his
design and the present operation of the Sand City Desalination project in Monterey,
Todd Reynolds of Kennedy/Jenks Consultants gave an overview of the project. From 2004-
2007 the Marin Municipal Water District conducted a desalination Pilot Program. Mr.
Reynolds' presentation covered the following points:
- Desal water = taking salt out of water
- 1,000 mg/L - 5,000 mg/L = brackish water. Brackish water is water with Total
Dissolved Solids (TDS) expressed in milligrams per liter (mg/L).
- 30,000 mg/l = seawater
- Can be achieved by evaporation or reverse osmosis
- Might have to add minerals
- Membranes are new technology - for a pilot study
- U.S. Bureau of Reclamation for permit required for pilot testing
- Use the beach as a filter to draw the water.
- The California Coastal Commission likes a sub-surface intake.
- 1 gallon of water = 1/2 gallon of sea water that is twice as salty.
- It takes seven to nine times as much energy as a conventional water treatment plant.
- A multi-year process if we did something in a small capacity.
- A brackish well would be the best scenario.
- What is the chemistry of the water?
- Manpower - needs maintenance - advanced water treatment
- Effects of climate change would be part of the study.
- Supply - how much you need
- Environmental and permitting
- Economics and public outreach
- Public acceptance
- Not for growth
- Need for it
Step 1: Update the "Water Supply and Demand Management Options" plan - update look at
Step 2: Feasibility study on brackish well?
The meeting was adjourned. The next regular meeting will be held at the District office on
Saturday, November 19, 2016, at 9:30 a.m.
