Fixing the economics of water conservation | Tom Ash | TEDxUCRSalon

[@droughtdietproducts4400]

Great talk and financial model - but i also think that there should be a elasticity price of water based on the two factors 1) amount of water in our reservoirs and 2) amount of water in our groundwater tables. The new California Sustainable Groundwater Management Act (SGMA) could change the item 2 as it become a law to maintain groundwater levels. Another model we have been playing with is changing the payer. In a Los Angeles City project, we had the water / electricity agency pay for energy savings of trees to shade a house and irrigated with greywater. The end results was a 40 year amortization to cool the house with natural shade, but at the same time the utility payed to divert the greywater to irrigate the trees and landscape, cutting the outdoor water consumption. The economics are in the energy and not the water.

Very good and understandable presentation.

A simplest way to save water in the world with no cost as follows: Step 1: At a washbasin - Just turn water tap maximum and measure total volume of water in a minute. That’s around 9 liters or more. Step 2: There is a knob below every wash basin. Step 3: Turn it little to reduce water flow. Step 4: Water tap maximum volume of water in a minute should be equal to 6 liters or near it. So, you save water 33% or more at the wash basin with no cost, time, or much effort. This makes it to be the Simplest way to Save Water in the World and it comes with no cost.

I love this video. It is no different than when you sign up for a data plan for a cell phone. If you have a 5 GB a month plan and you go over for the month you get charged more for going over your limit.

Mr. Ash, Excellent piece and well delivered. It appears your 34 HCF = 34 CCF (in our local terms) or 34 * 748 gallons...which are horrible units (HCF or CCF) on which to subject the masses. This is another thing the water industry needs to abandon in favor of 'gallons' or 'Kgals' when communicating to the public via billing or other outreach media. Thank you for this presentation.

Hi Tom - great presentation. Can't wait for updates.

A good talk to introduce key concepts but I am not sure how catchment management consideration and costs - to keep water clean, or factored into the equation? Or if this sustainable rate considers equity? For example, if I am rich, and have a big plot of land I am entitled to more cheap water than my less landed poorer neighbour?

[@allstatemademehomele]

Your point well taken

[@ergriffiths]

can anyone help me convert the calculation into metric units?

[@americanmeetsworld]

I like this talk. I love how you schooled Mr. and Mrs. Smith they're ignorance and entitlement was showing. I learned something too. Great talk!

I do not believe it, there has always been enough water. But I do believe a person can use to much water. A lack of a thing is always the first sign the water bill goes thru the roof. greed
