First High Reservoir, Baltimore District, Maryland. As part of a three-year Indefinite Delivery Contract with the Army Corps of Engineers - Baltimore District, NCS received its first Task Order to evaluate structural and hydraulic issues associated with the operations of a finished water service main and reservoir, which serve one of the four service areas by the Washington Aqueduct. To supply potable water to more than one million customers, the Washington Aqueduct treats the Potomac River water at the Dalecarlia and McMillan Water Treatment Plants. Finished water from the Dalecarlia Water Treatment Plant is pumped into the First High Reservoir through the First High Service Main. The First High Service Reservoir was built in 1924 and has been repaired several times for structural cracks and leaks. The reservoir has a capacity of 14.5 million gallons. Besides the structural issues, a number of hydraulic issues (such as commissioning of the new altitude valve and its concurrent operations with the first high main surge valves) will be studied as part of the Task Order. |

Agua Fria, AZ. NCS is assisting Arizona American Water Company in developing a strategy for incorporating a new surface water treatment plant into the service area of Agua Fria Water District (AFWD). NCS developed a new network that combined the two existing infrastructures into a single model. A detailed steady state and extended period calibration was carried out on the system. This was further used with advanced techniques, such as genetic algorithm, to develop an optimized cost efficient operational strategy that maximized usage of the White Tanks Water Treatment Plant without risking water quality violations at any location. This was achieved by using hydraulic modeling, water treatment plant modeling, NCS' genetic algorithm technology for advanced trial and errors, as well as water quality modeling. |
Rio Rancho, NM. Well 23 Equipping and Treatment. Due to an increase in population, the City of Rio Rancho continues to develop new water resources. A new well, Well 23, is being installed by the City. Based on its water quality, treatment would be required for total dissolved solids, arsenic, iron and potentially for radionuclides. The treatment train would be refined based on a preliminary engineering report (PER), which is underway. Design and construction of treatment and other related facilities (pumping station, storage tank, transmission main, etc.) for a 2,400 gpm facility would begin after completion of the PER. |

Santa Fe, NM. Buckman Wellfield Pilot Testing Study. The project consists of developing an arsenic treatment master plan for the Buckman Wellfield, owned and operated by the City of Santa Fe, New Mexico. As part of the project, pilot investigations will be conducted for three adsorptions (adsorption refers to the accumulation of material at the interface between two phases [water and solid media]), one ion exchange and two coagulation/filtration technologies. The pilot units have been assembled at Well 12, and the pilot study began in April. |
