.75 USD or Singapore Dollars?
- ghshephard 12y agoThanks for the correction, it's actually $0.49 USD m^3. http://www.edie.net/news/3/Black--Veatch-Designed-Desalination-Plant-Wins-Global-Water-Distinction/11402/ http://www.edie.net/news/3/Black--Veatch-Designed-Desalinati... Energy Consumption is 4.2kWhr/m3 - and that was in 2006. Presumably technology is improving. With reasonable conservation efforts (low flush toilets, low-flow showers, water efficient washing machine and dish washer) the average individual needs 200 liters a day, which, with desalination, would cost $0.10/day/person or $3/month to supply, (not including transportation - which isn't too expensive for coastal cities).

The 25-year WPA will see Hyflux deliver desalinated water – through a Design, Build, Own and Operate (DBOO) model - at a fixed low price of S$0.45 (USD $.36) per cubic metre for the first year Singapore has been leading the way with desalination research, with projects hoping to reduce current energy requirements for membrane desalination from 3.5 kWh to 0.8 kWh/m3, including work on biomimetic membranes If they do get it to .8 kWh/m^3, I expect we'll see wide(r) spread deployment in arid coastal regions like California for residential use.
