As part of the City of Delano’s Capital Improvement Plan, Delano Municipal Utilities (DMU) has committed close to one million dollars to replace and upgrade much of our aging underground water infrastructure. Some of these pipes were installed around and date back to the mid-twentieth century or even earlier.
DMU is working with a water/sewer contractor and the Engineer of Record (Wenck Associates) to identify any obsolete or damaged piping or any uncompliant materials according to the Minnesota Department of Health (MDH) drinking water standards.
Cement pipe was a very common material 70 years ago; unfortunately it also contained asbestos fiber. This fiber was used to strengthen the cement mix. DMU has identified some cement pipe (tradename Transite®) in our water distribution system and has been removing this pipe and upgrading to new MDH standards for water pipes. In addition, the new compliant pipe is stamped with the codes NSF-PW or NSF-61, ensuring that these pipes meet the American National Standards Institute (ANSI) standards for potable or drinking water.
Unfortunately asbestos goes far beyond water pipes. It was used heavily in the manufacturing of roofing, siding, insulation, flooring and wall board. Chances are if you live in a house built before 1970, it contains a fair amount of asbestos and lead material.
Both the MDH1 and the World Health Organization (WHO)2 have released studies which show there is no definitive link between cement pipe and any adverse health effects in humans. The MDH has no standards on asbestos contamination in drinking water. Delano water is tested monthly for compliance with basic water quality standards and quarterly for a rigorous barrage of tests. These tests include over 100 parameters including bacteria, organic and inorganic contamination, industrial chemicals, radiological elements and pesticides.
Regardless of these facts, it is in the best interest of our community that these old pipes be removed and replaced with safer materials. Fortunately, very little Transite® pipe has been discovered in the water distribution system, and it is being removed as soon as it is unearthed.
If you have any questions or concerns about water pipes in your area, you are encouraged to call the offices of DMU at (763)972-0557.

Main Utility Office and Generation Facilities
The photograph above shows the Main Utility office and Power Plant. The Utility Office is the central location for all operations. The Power Plant houses 5 of the 8 Utility Generators with the remaining 3 generation units and high voltage switch gear located behind the facility.
The Delano Municipal Utilities Power Plant is capable of generating a total of 24.35 MW. The picture above is a view of 4 of the 8 Power Plant Generators. Here you can see diesel engine Generators Number 2, 3, 4 and 5.
Above is a view of the Main Facility Power plant control panels. These control panels allow circuit operations and readings of important power distribution data throughout Delano.
Above is a view of Generator 9. This generating unit is jet turbine driven ( Photo Below). The jet turbine drives a mechanical reduction gear set and is connected to the main synchronous generator above. This unit is capable of generating 12.5 MW of power.

Located at the rear of the DMU facility are high voltage switch gear control panels. Above shows a lineup including the main SCADA interface computer that sends data to the main power plant.
