DENVER, CO -- The City of La Junta's New Water Treatment Plant and Denver Water's New Water Reuse Facility were both honored by the American Council of Engineering Companies (ACEC) at the 2005 Engineering Excellence Awards Competition in November.

Richard P. Arber Associates provided design services for both of these projects. La Junta's new water treatment facility produces 6.6 million gallons per day of water, making it the second largest Reverse Osmosis Membrane system in Colorado. The Southeastern Colorado City of 7,600 had over 50% of its residents drinking bottled water. With the new water system in place, residents have been able to do away with their home water softeners. Also, plumbing corrosion and soap use have been reduced, and the use of bottled drinking water has dropped below 5%.

Joe Kelley, Director of Water and Wastewater for the City of La Junta stated, "Through implementation of the Reverse Osmosis system our overall cost of water treatment has been reduced in La Junta and our customers think the water quality is great. The Engineers were able to create a Win - Win situation for all parties involved in the project and their dedication and attention to detail allowed the City to successfully complete the largest public project in the City's history."

The Denver Water Reuse Project was awarded an Engineering Excellence Award and will go on to compete in the National ACEC competition. The reuse facility supplies over 17,000 acre-feet of recycled water per year to both irrigation and industrial customers. The facility is the largest water reuse plant in Colorado and capable of producing 30 million gallons per day. The distribution system contains over 50 miles of pipe with 3 major pump stations and storage facilities.

Richard P. Arber Associates is an employee owned professional consulting engineering firm helping municipalities, special districts and federal clients in the U.S. The firm provides planning, design, and construction services for water, wastewater, and water reuse systems.

Water Safety : Sandia, Tenix, and CH2M Hill To Develop Automated Sensors

LIVERMORE, CA -- Sandia National Laboratories, CH2M Hill, and Tenix Investments Pty. Ltd. today announced a multi-year, multi-million dollar partnership to develop an unattended water safety system that offers the unique capability of detecting currently unmonitored biological agents such as bacteria, viruses, and protozoa that could threaten water supplies.

Current real-time, remote water quality monitoring is limited to detecting more traditional water-quality parameters, such as turbidity or the presence of dissolved solids, pH, nitrates, and ammonia.

“We applaud this first major agreement announced by Sandia to develop technology with such strong potential for homeland security applications,” said Carol Linden, deputy director of the Science-based Threat Analysis and Countermeasures for the Department of Homeland Security’s Office of Research and Development, part of the Department’s Science & Technology directorate.

“Our nation’s critical infrastructures can be better-protected through commercialization of national laboratory technologies such as Sandia’s microfluidics-based detection technology, µChemLab™ [MicroChemLab],” added Sandia/California Vice President Mim John, who also leads the lab’s homeland security efforts.

“CH2M Hill and Tenix have worked together in the past on water quality projects in Australia. With this project, they will deliver to the U.S. public a water safety system that is based on technology that Sandia developed,” said Matt Simmons of Tenix. “CH2M Hill is very excited to be associated with developing a cost effective solution that protects our nation’s water and wastewater systems,” said Tom Searle, president of CH2M HILL’s water business group.

“We are gratified that our earlier investment in research and development in this technology will be paying off for the nation’s security,” said Larry Adcock of the Department of Energy/National Nuclear Security Administration’s Sandia Site Office.

Tenix, Australia’s largest defense and technology contractor, working with Englewood, Colo.-based CH2M Hill, Inc., is funding research to develop, pilot, and demonstrate an Unattended Water Safety analyzer for use in potable water, reclaimed water, and wastewater systems. The analyzer is intended to add functionality and ease of use to Sandia’s µChemLab™ detection capabilities.

Initial commercial units and wider deployment are anticipated from late 2005 to mid 2007. The analyzer will respond rapidly to chemicals, biological agents, and biotoxins; provide a low level of false alarms; and can be deployed as part of an integrated water and/or wastewater monitoring and management system.

SPRING HOUSE, PA -- Siemens Energy & Automation introduces a new, maintenance-free, battery-operated magnetic flowmeter for irrigation applications including, measuring the water transport to farm outlets. Meters range is size for 2 inch to 12 inches in diameter.

The high accuracy and long battery life of SIEMENS MAG 8000 flowmeter offers a competitively priced alternative to propeller-style flowmeters. They feature higher accuracies up to 1% of actual flow. The MAG 8000 flow meter can also be installed directly on the water well discharge, which results in lower installation costs without sacrificing accuracy.

There are no propeller or bearings to replace, and the MAG 8000 is obstruction-free and with no moving parts. The only maintenance needed on this flow meter would be a 5-minute battery replacement. The MAG 8000 flowmeter will operate maintenance free for 6 years in a typical application.

The MAG 8000 is easy to install. Its low-flow tube design improves low-flow performance with minimal pressure drop. Each unit comes with an IP68/NEMA 6P enclosure, integrated data logger, and open communications platform. The MAG 8000 flowmeter complies with most international approvals.

Siemens AG (NYSE:SI) is a leading global electronics and engineering company with reported worldwide sales of $80.5 billion in fiscal 2003. With its United States corporate headquarters in New York City, Siemens in the U.S. has sales of $16.6 billion and employs 65,000 people throughout all 50 states and Puerto Rico. Eleven of Siemens' worldwide businesses are based in the United States. With its global headquarters in Munich, Siemens AG and its subsidiaries employ 417,000 people in 192 countries.

Peter wants to know an operating strategy:

Our plant has 4 - 4pass plug flow aeration basins with total volume of 20MG. The design capacity is 30MGD. But, normally we just run them at 8-10MGD. So, we just put two of them on line. When the wet weather comes, we need put all the basins on line quickly to take maximum flow we can.

My question is whether we can run all of them at low flow (8-10MGD) and at low energy cost. So, we can respond very quickly when storm come in.  Is there any suggestion about how to run the plant at low energy cost at low flow? (Click here to post a reply)

Ms. Barnes needs help with lagoons:

I am a grant writer and I am trying to help a small rural (pop 780) community with a lagoon system installed in the early 60's that is now holding to full capacity on each - almost at crises point.

I need input from some more educated minds that what is available at their level. They were told that sludge bugs (activated sludge) could cause even more problems if not handled right - But isn't it cheaper to have someone who knows how to handle their environment than install all kinds of new equipment?

I have no engineering knowledge in this area and trying to get some intelligent input.  (Click here to post a reply)
