If you are planning to attend the Pumper & Cleaner Environmental Expo International in Indianapolis next February, why not spend two days over the weekend attending one of the two pre-Expo workshops sponsored by NAWT? Consistent with our name change to the National Association of Wastewater Technicians, the classes emphasize the service connection. The inspection certification course will be offered, as it is every year, to anyone who would like to learn the NAWT standard for inspecting existing onsite systems. But we are excited to offer a course on the Principles of Septic System Design for the first time.

Over the years, NAWT has hosted a variety of courses during the two days leading to the Expo. The design principles course is the answer to numerous requests NAWT has received for such a program over the past year. Course content is from the perspective of what a service technician needs to know about design criteria. This will allow the technician to evaluate design plans so they understand why systems are installed a certain way, but also will help the service provider recognize potential problems that require their attention.

The first day of the course is in the classroom, discussing design principles. The second day is in the field, providing hands-on experience. You'll find out what impact the user has on system choices and design parameters. The most common mistakes are soils related, and the fundamentals will be taught to learn how to avoid these mistakes. System flow lines, sizing and layout, pumps, pressure distribution and advanced technology will be other topics of discussion.

Estimating hydraulic and organic loading from different types of users and how this impacts system design choice will be discussed and practiced in the field. Participants will go through a site evaluation process to understand how information gathered impacts the design process. Finally, the class will check the system layout in the field using basic surveying techniques. This course will not make you a practicing designer, but it will give you the ability to evaluate system plans and actual layouts, which as the technician caring for the system will be invaluable in troubleshooting problems and estimating what it will take for proper system maintenance.

Working with experts in the field and others in the industry, the course will give you a better understanding of design principles. With a combination of classroom and field visits, it is an ideal learning situation, including bookwork and hands-on interaction. If you are already NAWT-certified and need your CEUs, this will qualify for recertification.

Here is the lineup of NAWT seminars for the Feb. 25 Education Day at the Pumper & Cleaner Expo:

8–9 a.m. – Introduction to Pressure Distribution: Why Use Pressure Distribution? - Kit Rosefield

9:30–10:30 a.m. – Designing Systems, Boundaries and Barriers From a Soils Perspective - Jim Anderson

11 a.m.–noon – Pump Choices and Settings: Decisions for Proper Operation - Dave Gustafson

1:30–2:30 p.m. – Operation and Maintenance of Pressure Distribution Laterals - Bob Wright

3–4 p.m. – Installing With Management in Mind: How to Get the Most out of Your System - Dave Gustafson

4:30-5:30 p.m. – Introduction to Drip Distribution -Bob Wright

As an added bonus this year, there will be some special sessions on Tues-day morning, Feb. 26, of the Expo discussing DOT driver compliance issues and how to meet the 503 requirements for land application of septage.
