Purchase of Wastewater Diffuser System Repairs at the Greenfield Water Reclamation Plant for the Water Resources Department (Sole Source) (Citywide) This repair is needed because the Fine Bubble Air Header Diffuser System in Aeration Basin #3 has cracked piping throughout, causing the system to experience failures. Fine bubble diffusers are critical components in the aeration basin of a water reclamation plant, facilitating efficient oxygen transfer into wastewater. This process fosters the growth of beneficial microorganisms that break down organic matter, ammonia, and other contaminants in the water. The Water Resources Department and Procurement Services recommend awarding the contract to the sole source vendor, Environmental Dynamics International (EDI) at $180,000.
