From the Boulder Daily Camera (Brittany Anas):
… it may be at least another year before CU can begin recycling the dorm’s water through a planned pilot program. “It’s a simple concept,” said Moe Tabrizi, CU’s campus conservation officer. “The complexity is in the water law and water rights.”[…]
So far, CU has spent $230,000 on a plumbing system in the Williams Village North building capable of recapturing water from showers and sinks, sending it to a collection tank to be disinfected through a filtration system and then re-circulating it through separate plumbing system that would only be used for toilets, said Malinda Miller-Huey, a spokeswoman for CU’s Boulder campus.
Once CU gets the green light to use the graywater system, campus officials will need to install a collection tank and filtration system, according to Miller-Huey. She didn’t have a cost estimate for that portion of the project.
A bill introduced earlier this year would have given local municipalities greater control over graywater use, allowing them to pass their own regulations. The measure, which had Boulder County’s support, died in committee.
