before it shipped to Alaska’s newest fish hatcheries.

In an effort to replenish Alaska’s dwindling fish population, the Alaska Department of Fish and Game is on track to complete two fish hatcheries in Anchorage and Fairbanks. These hatcheries will be capable of producing several species of cold water fish for the stocking of area lakes, ponds and rivers at a cost of $96 million.

According to state-run website, Alaska.Gov, the new hatcheries are an integral part of a development strategy by the Sport Fish Division to ensure the continued and increased production of sport fish for the South Central Region and Interior Alaska Region. Each facility will be producing roughly six species of cold water fish: Rainbow Trout, Lake Trout, Arctic Char, Arctic Grayling, Silver Salmon, and King Salmon.

Alaska’s official website says that once completed, the 134,000 square ft. Anchorage Sport Fish Hatchery will be the largest enclosed sport fish hatchery in North America. Total production will depend on the desired species mix, release size and timing but full capacity production will allow for a 50% increase over historic stocking levels.

Metropolitan Industries was contacted by the Phoenix, Ariz. and Portland, Ore. Offices of HDR One Company to make recommendations for several booster systems for the Anchorage Sport Fish Hatchery. HDR is a global architecture, engineering and consulting firm that has recommended Metropolitan’s equipment in the past. Metropolitan was tasked with offering solutions for water pressure booster systems that would be an integral part of providing and regulating water and filtration systems within the hatchery. In order to avoid harming the fish, the systems would be designed with components that did not contain yellow metals. This improved aquaculture technology reduces the volume of freshwater required to raise the same quantity of fish and the energy required to heat water to an optimum fish-rearing temperature. It also reduces the amount of effluent water discharged from the hatchery.

HDR’s Phoenix office was in charge of designing the process water systems. These systems take tempered well water and introduce it to the hatchery’s filtration system and hold it in large reservoirs. Two of the Metropolitan packaged booster systems then take the water out of these reservoirs and “boost” it into the hatchery. The two systems handle the hot (65 -75° F) and cold (55 – 65° F) water.

The Hot Water Process System (HWPS) was designed as a triplex booster system that takes incoming well water and discharges it from a basin at the rate of up to 1,930 gallons per minute @ 50.3 feet of total dynamic head (TDH). Each pump is rated for 965 GPM at 50.3’ TDH, 20 hp, 460 volt with the third pump being a back-up.

The Cold Water Process System (CWPS) was also designed as a triplex system rated up to 2,268 GPM at 51.6’ TDH. Each pump on the CWPS is rated for 1,134 GPM at 51.5’ TDH, 25 hp, 460 volt. With the layout of the basin and control room already in place, the design selected was to use vertical turbine pumps with variable speed controls on this particular system.

Both systems required FDA approved fusion bonded epoxy coated fabricated steel piping (in compliance with NSF61) consisting of 10-inch branch and 16-inch headers according to Metropolitan Project Manager Bob Bukowski who coordinated logistics for the project. Bukowski said, given the size of the pumps, pipe work and valves, Metropolitan had to lay the systems out in a split-skid configuration. This method has each system built in two parts making up one complete system skid, which is easily assembled on site and makes handling during installation easier and shipment more practical.

HDR’s Portland office was in charge of the Influent Degassed Water System design. The degasser system functions just as the name implies, it removes the gas from the water. The water is then tempered and stored in above ground storage tanks. The layout that HDR already had in place had these holding tanks positioned above the location of the booster systems. Like the process water systems, the influent degassed water systems were designed in two parts: Influent Heater Degassed Water System (IHDWS) and Influent Chilled Degassed Water System (ICDWS). Both are designed in a duplex configuration with one pump being a back-up. The IHDWS is designed for 1,130 GPM at 50’ TDH while the ICDWS is designed for 1,261 GPM at 46’ TDH. Both systems are fitted with 20 hp, 460 volt motors and variable speed controls.

As with the process water systems, the piping on the degassed water systems is FDA approved, (NSF61) fusion bonded epoxy coated fabricated steel. All piping and valves on these systems are 10-inch. Due to the space allowed under the holding tanks, it was necessary to design a separate skid for the controls of each system. This allows for the systems to be positioned to line up with the piping of the tanks while putting the controls in an easily accessible area.

The construction of the hatchery is being managed by Kiewit, one of North America’s largest construction and mining organizations. Superior Plumbing and Heating, a sub-contractor of Kiewit, has been commissioned for the procurement and installation of the systems. All four systems shipped from Metropolitan in November of 2010.

Metropolitan Industries supplied a large air-gap break tank system that isolates processes from the source water feed for the Hanford Site near Richland, Washington.

Metropolitan Industries supplied a large air-gap break tank system that isolates processes from the source water feed for the Hanford Site near Richland, Washington.

The former uranium production facility in Hanford, Wash., one of the main locations for the Manhattan project due to its isolation and its proximity near the Columbia River, which could supply sufficient water to cool the nuclear reactors that produced uranium during World War II, has been focusing its efforts in the site’s cleanup and treating contaminated groundwater to ensure a healthy future for the Columbia River.

To accomplish this goal, Project Engineer CH2M HILL of Englewood, Col., has been working on groundwater treatment and remediation efforts through Hanford’s 100 area and Central Plateau, which includes a total of 11 groundwater operable units.

Although there is still a lot more work involved in the cleanup, the U.S. Department of Energy (DOE) recently announced that over 650 pounds of contamination from Hanford groundwater has been removed in the past two years, which has exceeded its goal by over 100 pounds.

In 2011, Metropolitan Industries supplied a large air-gap break tank system that isolates processes from the source water feed for the 200 Pump & Treatment facility at Hanford.

Working together with CH2M Hill, University Mechanical Contractors located in Mukilteo, Wa., and Metropolitan Representative PumpTech, Inc located in Moses Lake, Wa., Metropolitan Industries supplied a custom-designed triplex water pressure booster system with air gap protection for the potable water supply, a 2,100 gallon tank with a system capacity rated for 580 gallons per minute.

Other features of the system include a U.L. listed control panel with intuitive operator interface and touch screen control. This capability reduces costs while increasing quality.

According to a recent release from DOE and CH2M Hill, the ability to maintain a safe and ideal operation of its treatment technologies has allowed DOE to exceed in its groundwater cleanup goals again this year.

“Our contractor removed more chromium than forecasted this year by pulling more groundwater from the areas of highest contamination,” said DOE Richland’s Soil and Groundwater Division Director Briant Charboneau. “Having extraction wells in the right place and adding new treatment systems over the past few years has been critical to our success in removing contamination from groundwater and protecting the Columbia River.”

Metropolitan’s air-gap systems have become a major component in facilities where physical protection is needed. With the goal of protecting a city’s water supply, there is a real need for a reliable system that is a fail-safe solution to protecting the water.
