GHA’s expertise spans a wide range of water and wastewater system operations, from managing potable water treatment facilities to operating pump stations, we also work closely with private labs for water testing quality to meet all EPA standards and reporting, and Supervisory Control and Data Acquisition (SCADA) systems. We understand the importance of preventive maintenance programs and are equipped to respond swiftly and efficiently to emergencies. A key aspect of our work is managing overall water and wastewater systems to reduce Inflow and Infiltration (I&I) in sanitary sewer systems, demonstrating our commitment to maintaining water system from daily operation to all required field inspection of assets, and this is a based on the long-term functionality of these critical utilities.


GHA has embarked on a comprehensive investigation and management project of the Village of Wheeling’s storm sewer system. Our team utilizes GPS technology to locate approximately 530,220 linear feet of storm sewer pipes and conducts thorough inspections of more than 10,000 storm structures. Through personalized GIS data integration, we provide a comprehensive stormwater master plan to the Village, offering valuable recommendations for their storm system management.


Our Storm and Sanitary Structure Data Collection project for the City of Urbana exemplifies GHA’s commitment to meticulous data collection and efficient infrastructure management. The project, which covers approximately 80% of the city’s storm and sewer structures, employs a custom GIS-based form to gather comprehensive data and directly integrates this information into the city’s GIS data model. The anticipated use of the CUES SPiDER Manhole/Structure Scanner on around 25% of the structures enhances the project’s efficiency, offering robust 3D models that help identify potential defects. This innovative approach highlights GHA’s passion for leveraging advanced technology to serve our clients effectively and with integrity.
