Haulage of sewage is associated with which class of system?

• A. Class 2
• B. Class 3
• C. Class 4
• D. Class 5

Answer: (D)

Haulage of sewage is a way to manage waste without treating or dispersing it on the property. In the classification of on-site sewage systems, off-site removal by a licensed hauler to a treatment facility is grouped into a specific class designed for that purpose. This category recognizes that the waste is stored or collected on-site and then transported away, rather than being processed through an on-site septic system or soil absorption field. That off-site disposal approach is what makes it fit the designated class for haulage. The other classes describe systems that treat and dispose of wastewater on-site (such as septic tanks with soil absorption) rather than transporting waste off-site.
