This course will introduce you to small flow waste treatment systems such as septic tanks, waterless toilets, filtration and reuse systems, Imhoff tanks, and packaged treatment plants. You will learn about subsurface absorption and how to conduct percolation tests. You will learn how to utilize leaching wells, sand filters, mound systems and other methods of waste disposition. The systems you will be introduced to in this course will generally be applicable to facilities with a waste discharge requirement of less than 1.0 million gallons per day. This course will give engineers and others an introduction to small flow waste treatment systems that will be a foundation upon which to build their knowledge and skills needed to address small flow waste treatment design and construction issues on day-to-day projects.

Learning Objectives

• Learn the population limitations of septic tank systems
• Learn the importance of detention time when using septic tanks
• Learn how subsurface absorption is used in conjunction with septic tanks
• Learn the subsurface soil conditions required to utilize leaching wells
• Learn how to determine soil percolation rates
• Learn about humus composting toilets
• Learn the pros and cons of incineration toilets
• Learn how intermittent sand filters are used to treat waste from Imhoff and septic tanks
• Learn when conditions may dictate use of a mound system rather than a leach field
• Learn the soil and site factors that limit the use of mound systems
