Before any downspouts are disconnected, the City needs to confirm whether or not the downspouts that go into the ground are actually connected to the municipal sanitary sewer system. To do this, the following steps must be taken:
- Preliminary property investigation
General surveys of residential lots to identify if downspouts are discharging above the ground or into the ground.
- Sanitary & storm sewer smoke testing
Smoke testing within the sanitary and storm sewer systems, which involves blowing a non-toxic, highly visible smoke through the systems and observing the exit points of the smoke. This test can identify whether downspouts that go into the ground are connected into the sanitary sewer system or the storm sewer system. In addition, the smoke test also identifies other devices/equipment that are connected to the underground sewer system.
