Hydraulic Network Analysis Various Clients

NIES Engineering, inc. has comprehensive hydraulic network analysis (HNA) experience, extending from small 200 resident developments through full multiple city models. NIES Engineering maintains the HNA model of the City of Hammond Water System for the Hammond Water Department. The model contains nearly 2,000 pipes, and more than 1,500 junction nodes, three elevated tanks and five high service pumps. Proposed improvements can be investigated, and actual changes made are added as an on-going process. The model has been particularly effective in assessing the system's ability to accommodate additional customers. Following a set of successful scenarios modeling Griffith as an additional Hammond customer, the adjoining community is in the process of being supplied by the Hammond Water Department. Also in Hammond, Indiana, the Hammond Housing Authority has benefited from an HNA study conducted by NIES Engineering. The site has over 400 apartments, and multiple main breaks caused by ageing corroded water main were proving to be a major inconvenience. The Housing Authority called in NIES Engineering, Inc. to analyze the problem, and provide a cost-effective solution. We then conducted a Hydraulic Network Analysis to establish the most suitable water main replacement strategy. Based on our recommendations, the existing 19,000 feet of cast iron 3", 4" and 6" water main was then replaced with less than 10,000 feet of new 8" ductile iron water main. The improvements afforded greater fire flow capacity, and system pressures. New Buffalo, Michigan benefited from an HNA study by NIES Engineering that recommended system improvements and helped to size and locate a new elevated tank. In addition, the model was used to examine the effects of a proposed casino on the water system, and ensure that the short and long term effects were fully understood before the project commenced. As a result, funding was requested from the casino to pay for plant and system improvements prior to the commencement of construction and water service. HNA modeling for the LaPorte Water Department in LaPorte, Indiana helped us to correctly size and locate a new elevated tank. Following the successful completion of this project, the model was again used to size new high service pumps at both treatment plants, as part of a major Water Improvement Project. Accurate modeling ensured that the new pumps are well matched against typical demands, and the new motors are more efficient providing significant power savings. Whether you need to resolve distribution system problems, plan for future demands, or introduce new components to your system, NIES Engineering, Inc. has the Hydraulic Network Analysis experience to guide your project to a successful conclusion.
