A large supermarket chain with more than 200 locations across the Northeast and Midwest experienced persistent drain blockages in food preparation areas. Fat, oil, and grease (FOG) accumulation in floor drains and grease trap lines created frequent plumbing issues, resulting in costly maintenance and operational interruptions.
To address the issue, the company implemented a biological drain maintenance program using Drain BioTreatment, designed to break down organic waste and maintain free-flowing drain lines. The program significantly reduced clog incidents and helped lower maintenance costs.
During the initial evaluation, facility personnel identified floor drains in several food preparation areas—including rotisserie/fryer stations, deli preparation areas, and butcher shop drains—as the primary sources of recurring clogs.
To address the issue, Drain BioTreatment was introduced as part of a biological drain maintenance program designed to degrade accumulated FOG and organic residues.
Automatic dosing systems were installed in key locations to provide consistent application:
Because the butcher shop floor drain was located in the center of an open room and could not accommodate an automated dosing system, manual dosing of approximately one quart every few days was implemented.
This dosing program allowed beneficial microorganisms to continuously degrade organic material within the drain lines and grease trap system.
Prior to implementation, the test location experienced 18–25 drain clogs per year, costing approximately $6,000 annually in plumbing maintenance.
Following implementation of the Drain BioTreatment program:
The reduction in drain blockages significantly decreased maintenance disruptions and associated costs.
Due to the success at the initial location, the program was expanded to additional stores across the chain. When projected across all locations, the company estimated potential savings approaching $872,000–$900,000 after product costs.
Additional operational benefits included:
The implementation of a biological drain maintenance program using Drain BioTreatment significantly reduced FOG-related clogging issues within grocery store food preparation areas.
By maintaining cleaner drain lines and reducing organic buildup, the facility was able to lower maintenance costs, improve operational efficiency, and minimize disruptions caused by recurring plumbing issues. The success of the initial trial led to expanded adoption across additional locations.
