Fats, Oils & Grease Program
Grease is a problem. In the sewage collection and treatment business, grease is singled out for special attention because of its poor solubility in water and its tendency to separate from the liquid solution. Large amounts of oil and grease in the wastewater cause trouble in the collection system pipes and the wastewater treatment plant. It decreases pipe capacity and, therefore, requires that piping systems be cleaned more often and/ or some piping to be replaced sooner than otherwise expected. Grease in a warm liquid may not appear harmful. But, as the liquid cools, the grease or fat congeals and causes nauseous mats on the surface of settling tanks, digesters, and the interior of pipes and other surfaces which may cause a shutdown of treatment plant units or messy backups in your home or business.
Industrial Pre-Treatment Program
Clean Water Services recognizes that businesses and industries discharging stormwater and non-residential wastewater may face a complex and often confusing array of regulations. For this reason, the District’s Industrial Pretreatment Program provides an introduction to the rules and regulations associated with the District’s Source Control Programs.
Industrial Stormwater Program
The Tualatin Watershed resources—its streams, lakes, wetlands, groundwater, and the Tualatin River—play an important role in the quality of life we enjoy. They provide us recreation, irrigation and drinking water; support tourism and salmon; and are used by business and industry. These waters, however, are vulnerable to pollution from a wide variety of human activities. Many of our water pollution problems are due in large part to pollutants that are washed off the land by rainstorms. The quality of stormwater from public facilities, commercial and industrial businesses, and agricultural lands is an increasing concern nationwide. Many people believe that stormwater is clean and does not harm water quality. This perception is understandable since the amount of pollution from any one spot is not usually significant by itself. But when all these small amounts are combined, they can cause significant water quality problems.
