Global Water Center Field Trip, Saturday Nov. 15, 2008

Please join us for a guided tour of the Global Water Resource's state-of-the-art Global Water Center in Maricopa, Arizona. Global Water Resources is an Arizona-based water utility known for its leadership in water conservation through recycling and reuse. The Global Water Center is the first Leadership in Energy and Environmental Design (LEEDİ) Silver Certified utility facility in Pinal County . Ultimately, the Global Water Center will serve over 100,000 homes, care for over 300,000 customers, and create over 100 jobs for the city of Maricopa . Currently, the Center educates thousands on the benefits of water recycling and has hosted both local and international conferences on long-term water sustainability. Along with those exceedingly positive effects, perhaps the most notable impact is what the Center does not do… It does not use one drop of drinkable water to flush toilets, water plants and grass, or fill a water feature. The Center uses 80% less drinkable water than a traditionally constructed building of the same size. It does not consume nearly as much power as a typical building. Taking maximum advantage of natural light and high-efficiency heating and AC, the Center uses only two-thirds the electricity of an average commercial structure. It does however, have countertops, concrete form walls, ceiling tiles, carpet, asphalt paving, and metal parking canopies all constructed from recycled materials. And at least 50% of construction, demolition and land clearing waste was recycled or salvaged, effectively diverting it from landfills. Contact Ted Lehman (480-222-5709) if you are interested in attending. He will be organizing a carpool from his office in south Tempe ( 8400 S. Kyrene Road ) for interested persons. The tour starts at the Global Water Center at 9 am, so we’ll plan to leave Tempe about 8:15 am to make sure we arrive with time to meet our tour hosts. You are also welcome to meet us at the Global Water Center . Hope to see you there!


Zuni Basin Fossil Field Trip, near Springerville, AZ
Trip has been rescheduled: Date TBD

The Phoenix Chapter along with assistance from Erin Young, Fluid Solutions, & Richard Brose, Four Corners Environmental, of the Flagstaff Chapter are coordinating a field trip to a very unique spot in northeastern Arizona to examine real life dinosaur fossils! Our tour guide will be Doug Wolfe, Renaissance Environmental Management, L.L.C.

The trip has been rescheduled, date to be determined. Remember its four hours to Springerville and then an hour of so of dirt to get to the site. So interested participants will probably need to leave early afternoon on Friday to get to Springerville for the early Sat. departure. Folks can plan to stay in Springerville at Reeds Lodge on Friday and Saturday and return home on Sunday evening. The room rate we’ve been offered is very reasonable, running between $45 and $63 per night depending on the room type. Yes, camping is cheaper but is logistically more complicated and slows us down a lot based on Doug’s experience. However, you’re welcome to meet us at Reeds Lodge Sat. for an 8:30 am departure.

The field excursion itself will take place on Saturday and Sunday. We’ve decided to let individuals figure out their own food logistics, but we encourage cooperative efforts. Lunch will be on the road but breakfast and dinner can be rounded up in the Springerville area. The sites are at 7000 feet or so and very remote. People need to be in pretty good shape (probably no problem for this group.) We will limit the number of vehicles to 2 or 3. We investigated renting vans, but the cost is pretty high. So, if an interested party has a 4WD suburban or large crew cab, please let us know!

People will need to know there can be no private collecting. The sites are permitted Federal property. We will have to have people sign a statement accepting these conditions and agreeing to keep the sites confidential. We basically say the field vehicles leave from Reeds each morning about 8:30 to the site. If not on the bus, please enjoy beautiful downtown Springerville. Doug says you will see why this is necessary if you come. We will see dinosaur bones, fossil trees etc in the field and trackways and explore some promising territory.

Ted Lehman plans to arrange a carpool from Tempe Friday afternoon Oct. 10 for interested parties in the Phoenix and/or Tucson areas. He has room for two or three others. Erin and Richard will also be leaving from the Flagstaff area. Contact them for additional details.

Persons interest in the field trip in the Phoenix or Tucson areas should contact Ted Lehman or those in the Flagstaff area contact Erin Young (eyoung@flusol.com).

Thanks again to Doug Wolfe for volunteering to share this great field experience with AHS.


Surface Water Issues Workshop – Great Success!

The Phoenix Chapter’s second Technical Session was held on May 15, 2008 at ADWR. We had an excellent, highly informative day with nearly 70 attendees! Our primary beneficiary, 2008 Herman Bouwer Intern, Cheri Topel, was also in attendance and provided assistance with the day's event. Thanks in part to our sponsors, ADWR, Arcadis, EEC, EL Montgomery & Associates, Golder Associates, Lewis & Roca, and PBS&J, Cheri's intern stipend is more than adequately funded!

We’d like to thank our sponsors, speakers, and participants for a supremely successful event. We look forward to another technical seminar in the near future.

We would also like to send special thanks to all our AHS volunteers who made this event happen. In particular, we'd like to thank Lee-Anna Walker for spearheading this effort and Matt Beversdorf for coordinating with ADWR and maintaining our website for the event. If you see Lee-Anna or Matt, please express your thanks.
