Our team was tasked with developing a biosolids master plan to minimize disposal costs for a wastewater treatment plant serving the residents of Summerville.
After performing an analysis, KCI recommended a phased approach that included digester upgrades, big bubble mixing, new belt filter presses, and the future addition of solar drying technology, an energy-efficient system used to reduce the moisture content of biosolids through natural solar heating and controlled ventilation. Shortly after our recommendations, changes in landfill requirements caused disposal costs to double, accelerating the need for a more immediate solution. Based on our analysis, SCPW chose to proceed with the design and construction of an on-site solar biosolids drying facility. The drying process takes place in an enclosed structure, often designed as a greenhouse-style building, where biosolids are exposed to sunlight and mixed or turned regularly to accelerate evaporation.
KCI led the planning and design efforts, helping SCPW select equipment and coordinate a Construction Manager at Risk (CMAR) delivery method to stay on budget and meet scheduling goals. The upgrades are expected to reduce biosolids volume by over 85%, resulting in major cost savings and compliance with disposal standards. This comprehensive approach supported making an informed investment that provides long-term operational and financial sustainability.
