We have a project that will treat all waste water and use it for the cooling towers. Will this use be compliant with the credits requirements regarding the compliance path 2?
The waste water will be treated to tertiary standards.
We will also treat waste water for some future buildings that will be adjacent to the project.

Yes, David—that would be an appropriate use for the treated wastewater.

Tristan, what if the cooling towers' water consumption is a lot below the treated water to a tertiary standard.
We could use the remaining for landscape but ours will be so small that there still will be some treated water without any use.
The project will not use treated water for toilets nor urinals because the project is so high that having double pipping will not be cost efective and the local engineer has experience lots of trouble with toilets and urinals turning yellow with treated water so the client does not want to use it for such uses.
Will pouring the remaining treated water to the sewage comply with the requirements given that cooling towers' water consumption and landscape has been satisfied?

David, if you pour any treated water down the drain, you can't get credit for that water under WEc2. According to the requirements, treated water must be reused or infiltrated on site.Does that make sense?

I was thinking, our poject is attached to a huge mall. I was wondering if using the remainning treated water can be used for irrigation at this building that is attached to us.
If we do this, the water will be reused (out of the leed boundary though). But it will never reach the seweage.
Will reusing this treated water in another building comply with credits requirements?
