Typical Maintenance Activities
TVI stands for televised video inspection. A TVI allows us to get “eyes” inside the pipe by inserting a closed-circuit camera. TVIs are a very important part of our maintenance process, as they allow us to quickly assess a pipe’s condition and identify what may be obstructing flow or causing problems for customers.
A lateral is a section of smaller pipe that transports sewage from a customer’s property to SASD’s main sewer line in a street or a utility easement (see our 3D Sewer Diagram for a good visual). The lateral consists of a customer-owned upper lateral and an SASD-owned lower lateral. The upper lateral is the responsibility of the property owner to maintain, while SASD is responsible for the lower lateral.
