Thousands of projects to purify drinking water for municipalities are in planning and construction. Most of these projects are to replace plants as old as one hundred years.
The number of projects generated by demand growth is comparatively small. Changing environmental and regulatory requirements are a third driver. All these projects are tracked in North American Public Water Plants and People published by the McIlvaine Company.
A prime example of replacement of ancient systems is in Sacramento, California where $240 million has been appropriated to rehabilitate the city s two major water treatment plants. Most of the renovation will occur at the 90-year-old Sacramento River Water Treatment Plant, but work also will be done on the Fairbairn Water Treatment Plant on the American River in east Sacramento.
The Sacramento River Treatment Plant was built in the 1920s and, officials say, has outlasted its useful life. It can treat 135 MGD, but utility officials said they want to increase that capacity to 160 MGD to meet future demands.
Ithaca, New York is finally moving ahead to rebuild a 110 year old plant. The city began evaluating its options for water service in 1996. In 2005, the rebuilding of the city s system or purchasing water from Bolton Point were identified as the two alternatives for evaluation by the city, and in 2009, Common Council approved the rebuild option. Site plan review for the $37 million project was completed last year. The project will put the city in a good position for the next one hundred years. The plant will use advanced technology as the first large plant in the area to use membranes for water filtration, a technology that is becoming more mainstream.
The Southern Delivery System (SDS) will break ground this year for a $125 million facility to treat the raw water that will be pumped from the Pueblo Reservoir to Colorado Springs.
The SDS water treatment plant, which is being built near Pikes Peak, will be able to clean 50 MGD of water. Discussion of a regional water delivery system began more than a decade ago to address the water needs of a growing population in the Pikes Peak region. The project is estimated to cost $1 billion, but could come in under budget because of favorable financing conditions.
SDS is expected to be operational in early 2016, and it could take nearly that long to complete the water treatment plant.
Recently, representatives from HDR, Inc. outlined for the Yankton City, S.D. Commission approximately $28.7 million in upgrades it believes are necessary for the community s water treatment system.
The improvements include:

The improvements include:
- decommissioning Water Treatment Plant No. 1 as a treatment facility due to its 74 years of service,
- making improvements to aging equipment in Water Treatment Plant No. 2, which was built in Riverside Park in 1972,
- adding a new treatment plant adjacent to Treatment Plant No. 2 that would have the capacity to treat 5 MGD and would become the primary treatment facility, and
- adding a new water source, likely a collector well at Paddle Wheel Point that could deliver at least 5.8 MGD
Ralated Article: Pumping Without Air Inclusions
Air inclusions encountered during pumping of media pose, in many regards, a variety of problems. Pumps cannot reach their full capacity during suctioning, the motor is overloaded and foam formation complicates delivery. A venting valve from Schmalenberger provides help in this respect.
The ½ inch valve can be retrofitted and enables the rapid venting of air in the pump system. As a result, maximum pumping capacity is achieved again, rapidly and without complications, while additional foam formation in the pumped medium and dry running of the pump motor are prevented. The IPE valve was specially developed for SM series self-priming waste water pumps. In addition to relieving stress on the pump motor, the IPE valve primarily embodies economic advantages, as preventing performance losses saves energy.
Schmalenberger offers self-priming sewage pumps for clean and polluted liquids or media with gaseous inclusions. Main fields of application: coolant supply, environmental protection technology, surface technic, water supply and -filtration. Special version with sealing chamber.
The SM serie is Schmalenbergers answer to the complex challenges faced in the customers process chain: delivery without mechanical comminution, no complex lifting equipment, self-priming where even zero levels and severely foaming fluids are involved, selectively available with a sealing chamber to protect the mechanical seal, as a dry installation with space-saving and compact installation. An extremely varied model range has made the SM extremely successful favourites in mechanical engineering. A variety of uses are possible: from small machine tools to heavy metal machining, from production involving metal machining to grinding, water jet cutting to recirculation pumps.
