Miscellaneous Services Hydraulic Water Modeling and Analysis: Clanton, Alabama The City of Clanton, Alabama Water Distribution Model was developed by AME to analyze existing operating characteristics, and to allow analysis and design of future additions to the system. The system model utilizes information on pipe sizes and lengths, booster pumps, control valves, storage tanks, and demands (flow requirements) to calculate steady state flows and pressures for the entire system. Included in the Distribution Model are various background images such as digital USGS quadrangles and aerial photographs. Calibration of the model is achieved by using actual fire hydrant flow data gathered throughout the whole system. The model is capable of performing extended period simulations which take into account varying storage tank levels and demand patterns over time. Proposed additions or changes to the system are easily simulated and evaluated for effects to the entire system. Utility Mapping: Clanton, Tallassee, and Roanoke, Alabama Utility mapping databases have been developed which include the locations of: sanitary sewer manholes, water and gas valves, and fire hydrants. This data was collected using a Trimble Pro XRS Global Positioning System (GPS) Receiver. After processing the data, it was incorporated into ArcView, a geographic information system (GIS) software program to produce highly accurate mapping. Uses for this data range from simple mapping to development of an interactive database for use by personnel in the field. Drainage Study: Opelika, Alabama The City of Opelika, Alabama desired to formulate a long range plan to reduce or alleviate flooding within their corporate limits. AME was chosen to conduct a study and make the necessary recommendations to achieve these goals. The study was based on current land use and zoning ordinances with the premise that future development would manage stormwater runoff so as not to adversely affect the current hydraulic and hydrologic characteristics of their watersheds. Detailed topographic information provided by the City along with USGS Digital Elevation Models (DEM's) were used to develop and analyze models of the various watersheds. Recommendations and their subsequent cost estimates were provided in the report for planning purposes along with floodplain mapping. Sanitary Sewer Flow Monitoring: Prattville, and Tallassee, Alabama The Cities of Prattville and Tallassee, Alabama have used AME to conduct flow studies at strategic locations within their sanitary sewer system. Portable doppler-ultrasonic flowmeters were used to determine wet and dry weather flows which revealed areas which were susceptible to inflow/infiltration (I/I). Those areas which were shown to be susceptible to I/I were then prioritized for rehabilitation purposes. Flow monitoring has also been used to aid in design of new additions to the sanitary sewer systems. Source Water Assessments: Clanton, Tallassee, and Roanoke, Alabama The Cities of Clanton, Tallassee, and Roanoke, Alabama chose AME to conduct their Source Water Assessment in support of the Alabama Department of Environmental Management's Source Water Assessment Plan. These reports were prepared to comply with the U.S. Safe Water Drinking Act Amendments of 1996 and the subsequent guidance document prepared by the U.S. Environmental Protection Agency (EPA). The purpose of these reports is to systematically identify possible contaminant sources within a watershed area, and to evaluate the relative susceptibility of the treatment works to these sources. A detailed topographic map of the study areas along with possible contaminant source locations was provided with each report.
