Site Visit Day 1: May 30, 2012 (Wednesday)
75th Street Wastewater Treatment Facility
Location: 4049 N. 75th Street, Boulder, CO 80301
Time: 2.00pm
75th street Wastewater treatment plant is basically designed to treat up to 25 million gallons per day of wastewater from the City of Boulder, including the Gunbarrel Area.
The treated wastewater effluent from the plant is discharged to the Boulder Creek, just East of the 75th street.
The tour for this water team site visit is guided by Cole Sigmon. The purpose of this tour is to learn more about the treatment processes and have a clear look on how Boulder treat the wastewater from the city. We have the chance to look at the physical treatment process, biological treatment process and chemical treatment process. Besides, we also learned about the Biosolids processing and Dewatering.

Site Visit Day 2: May 31, 2012 (Thursday)
1. Center for Resource Conservation (CRC)
Time: 9.00am
Meeting with Kate Gardner, the water program manager of CRC. The CRC reaches out to and engages these individuals through programming in its energy, water, and waste divisions. Through the meeting with Kate, we learned about the water conservation issues. CRC's water division helps residents and businesses reduce water consumption by encouraging the efficient use of water. The Slow the Flow Colorado Program offers free sprinkler inspections, or indoor water evaluations, to customers of partner water providers. The Garden-In-A-Box Program sells professionally-designed, pre-planned xeric gardens to make xeriscaping easy. Free Water-Wise Landscape Seminars also cover xeriscaping and sustainable landscaping topics.

2. The Betasso Water Treatment Plant
Location: The Betasso Water Treatment Plant
Time: 11.30am
Meeting with Mr Randy. The Betasso Water Treatment Plant processes water from the Barker and Lakewood Reservoirs. Barker is fed by the Middle Boulder Creek Watershed. Lakewood is primarily fed by water from Silver Lake (a city owned watershed) via the Silver Lake pipeline, but may also receive water from North Boulder Creek and Como Creek.
We learmed the treatment processes of the water treatment plant and see how the by-product of the treatment which is sludge being disposed.
Besides, Randy also gave a short tour for us to visit the hydroelectric power plant where the electricity generated is sold to the other company and it's not used for the water treatment plant.

3. Boulder Reservoir Water Treatment Plant
Location: Boulder Reservoir Water Treatment Plant
Time: 2.00pm
Boulder Reservoir Water Treatment Plant - During most of the year, water is pumped directly from the reservoir itself. From about May through October, the Boulder Reservoir Water Treatment Plant may divert water directly from the Boulder Feeder Canal. Most of the water in the canal comes from Carter Lake and is much less mineralized (softer) than the water in Boulder Reservoir. We learned about the treatment processes in the water treatment plant and compare between the Betasso water treatment plant with the Boulder Reservoir Water Treatment Plant. The sludge in the Boulder Reservoir Water Treatment Plant is being disposed by using the method of floating.

4. Meeting with Jonathan G Akins, campus Civil Engineer, Facilities Management - Engineering and Sustainability of University of Colorado, CU
Location: Research Lab No.2 (1540, 30th Street) Room 369
Time: 3.30 pm
Jonathan G Akins is a campus civil engineer in University of Colorado. He proposed the action plan for the graywater system to be implemented in William Village which is a resident hall at the University of Colorado.
The University of Colorado's new green-themed dorm is equipped with the plumbing system needed to trap wastewater from showers and sinks, sanitize it, and then recycle the water so it can flow through toilets. However, it is now still in the process of applying the water right to reuse the graywater. As the water right in Boulder is 'first come, first use' principle.
While this graywater reuse system is using the recirculation of the graywater and go through filtration as well as disinfection with Chlorine, and finally to be used to flush toilets.
Besides, Jonathan also mentioned water from the river stream is pumped to the pond by gravity to pond in CU, then the water in the pond is being used for irrigation (water spritzer). CU indirectly used the rainwater as the source of the water for irrigation as the water from the river stream is coming from the rainwater.
