How do you get sewer service to approximately 120 households in high water conditions, that won’t let traditional septic systems function, west of Lamar, Colorado? You install grinder pumps at each residence piping it through over 75,000 feet of pressurized sewer lines back to the City of Lamar sewer main. That is what Carrigan Excavating completed in 2003 for Prosperity Lane Water and Sewer Association.

New water mains, valves, and fire hydrants with a state of the art radio read meter system and a half a million gallon water storage tank was completed for the Town of Sugar City, Colorado.

The Town of Swink, Colorado received new water mains, valves, fire hydrants, and a radio read meter system on a dual water system. This dual water system has hard water for exterior use and soft water for interior use. Carrigan crews crossed existing utilities over 1500 times on this project.

Down the road another crew was installing 25,000 feet of new water mains for the McClave Water Association.

In 2005 Carrigan crews started the Town of Wiley, Colorado Water Project. It consisted of bringing new water from wells 10 to 11 miles away. While crossing very rugged terrain, from sand to rock, and under the Arkansas River, along with various State Highways, roads, and canals. This job included installing a state of the art SCADA System and a TONKA Filtration System at their main site and drilling another new well.

A Kinetico Nitrate Removal System with lagoons, fencing, and a new well site facility which was put on line for the Town of Haswell, Colorado in 2006.

In Pritchett, Colorado we had to demolish the existing 145 feet tall water tower to install a new 300,000 gallon water storage tank.

We worked with Michel’s Corporation doing excavation, grade work, and supplying aggregates for the Twin Buttes Wind Farm project in southeast Colorado.

Also the City of Fountain, Colorado water main installation was completed in 2006.

Starting in 2007, work for the Cherokee Metropolitan District included installing water mains outside the city of Colorado Springs, Colorado. The project enabled the district to interconnect with Woodman Hills and running lines to a newly drilled well.

The Town of Bethune, Colorado was unique in the fact that they had no water metering system at all. Carrigan Excavating helped bring them into the 21st century by installing new water mains, valves, and fire hydrants throughout the entire town. Also installing a radio read meter system and a well house to work along with the new 300,000 gallon water storage tank.

A USDA Forest Service project in southeast Colorado was a change of pace for us. Our crews built a new auto and hiking trail through parts of the Comanche National Grasslands in Carrizo Canyon.

A devastating tornado swept through the Town of Holly, Colorado in the spring of 2007. During the fall and winter of 2007, Carrigan Excavating was awarded the contract to help rebuild Holly’s infrastructure including water mains, fire hydrants, valves, a touch read metering system, concrete curb, gutters, and sidewalks.

Offices for the National Park Service at the Sand Creek Massacre National Monument were completed with wells, water lines, and sewer service.

In 2008 the Town of Kanorado, Kansas water line improvement job was completed by installing new water lines, fire hydrants, valves, and a touch read meter system.

A few months later Genoa, Colorado acquired a 30,000 foot new raw water line along with a well house, fire hydrants, and valves.

At the end of 2008 and the first part of 2009 we are working on the Kim, Colorado project. They received more than 30,000 feet of of water lines. The entire town was set up on a new touch read meter system. Soon we will be building them a quarter million gallon water tower which will provide for the town's water needs for many years to come. They also received a 228,000 gallon bolted steel potable water storage tank that was 17.5 feet in diameter and 127 feet in shell height. The new tank will provide for the town's water needs for many years to come.

Also in 2009 we are working in Bent County for Smartt Ranches installing 40,000 feet of water lines, stock tanks, float chambers, a well house, booster pumps, and solenoid valves. All of this project was a Carrigan Design Build.

The Lamar Municipal Airport put a fencing project out for bids early in 2009. It was very good to have a project in our own backyard and our employees enjoyed being home for awhile. During the spring and summer installation of 20,000 feet of 8 foot high woven wire wildlife fencing was completed around the entire perimeter of the airport.

Later in 2009 we started another project in Lamar. The Lamar Light and Power Stormwater Management Drainage System Construction project was our next job. It included building access roads with concrete curb and gutter, retention ponds, holding areas and a drainage system. Over 30,000 tons of aggregate was supplied by our aggregate division, Riverside Aggregates, LLC. Our crews completed the project for the new coal fired power plant addition in the spring of 2010.

Simultaneously we started work on the Town of Seibert, Colorado Water Systems Improvements Project. The winter of 2009 - 2010 was very severe. Our devoted crews had to work through a long winter with numerous days of incredibly cold, snowy, and blizzard conditions along with frost deep into the ground. Over 10 miles of transmission water main line was installed along Highway 24 in between Seibert and Vona. The town was such a pleasure for us to work with, but it happened to be one of the first American Recovery and Reinvestment Act Stimulus Package projects in the state of Colorado. To say that the additional paperwork, to verify all of our parts were adhering to the Buy-American requirements, was grueling is a huge understatement. This was a great challenge for the town, engineer, suppliers and our office, but we are proud to say that we did everything we possibly could do. In town improvements were completed with a state of the art SCADA System and a top of the line Back-up Generation System, along with bulk water loading station dispensing unit.

In the fall of 2010 we were blessed to land the City of Ashland, Kansas project. The water system improvements project includes installing 10,000 feet of 6" C900 PVC pipe, 4,000 feet of 1" service line, fire hydrants, and valves. We are looking forward to working in their warmer temperatures this winter.

These just highlight some of the projects we do. These projects go on while we also take care of many local customers, including several feedlots, farmers & ranchers, and local contractors. We strive to treat our customers, employees, and subcontractors with integrity, respect, and fairness. This philosophy has lead to substantial growth in our company. We look forward to more growth and the challenge of bringing our customers project to completion in the most cost effective manner.
