- Clarion Water Treatment Plant: The City of Clarion contracted with ISG to assist them with the planning, design, and construction of a new reverse osmosis water treatment plant capable of producing approximately 1 million gallons of water per day. The reverse osmosis system includes the membranes as well as pressure filters, holding tanks, transfer pumps and chemical feed systems necessary for the proper treatment of the water. Also included in this project were the installation of three vertical high service pumps and the rehabilitation of a well house. This project was funded through USDA and SRF funding sources. ISG provided the preliminary engineering report, pilot water plant assistance, funding assistance, survey, design, permitting, bidding, and construction phase services for this project. The water treatment plant is currently under construction with a completion date scheduled in mid-2024.

- Rockwell City Water Reclamation Facility Improvements:  The City of Rockwell City contracted with ISG to assist them with the planning, design, and construction of improvements to their existing water reclamation facility to provide for the treatment of a daily average of 350,000 gallons of sewage, with a total capacity to handle up to 3.8 million gallons of sewage per day during a wet weather event.  The reclamation facility consists of headworks, equalization basin, and an activated sludge treatment process consisting of anaerobic, anoxic, and aeration basins and sludge pumping, storage, and handling facilities.  Also included in this project was providing uv-disinfection of the effluent prior to discharge along with a process building and associated mechanical, electrical, and plumbing systems.  ISG provided the preliminary engineering report, funding assistance, survey, design, permitting, bidding, and construction phase services for this project.  The facility improvements were completed in 2023.  

- Sanitary Sewer and Wastewater Treatment Plant Improvements – ISG developed cost – savings solutions to lower the chloride and e. coli effluent levels to meet State standards for the City of Pocahontas’s wastewater treatment plant and recommended efficiency improvements to its aging sanitary sewer system.
