How venting systems improve wastewater network performance

How venting systems improve wastewater network performance

To keep wastewater networks operating safely and efficiently, modern systems use specialised vents that manage airflow and pressure within underground pipes. Two key components in this process are in‑duct vents and e‑duct vents, each playing an important role in maintaining the reliability and safety of the network.

What are in‑duct vents?

In‑duct vents allow air to enter wastewater pipes, helping to balance internal pressure as water moves through the system. This prevents common issues such as:

• slow or uneven drainage
• gurgling noises in household plumbing
• sewer gases being drawn into buildings

By stabilising pressure, in‑duct vents support smooth wastewater flow and protect the internal surfaces of the pipes.

In‑duct

What are e‑duct vents?

E‑duct vents release built‑up air and gases from the network safely above ground. This controlled ventilation helps:

• reduce odours at street level
• prevent pressure build‑up in pipes
• maintain a safer environment for the community and maintenance crews

These vents ensure that gases are directed upwards and away from populated areas.

E‑duct

Why these vents matter

Working together, in‑duct and e‑duct vents help:

• keep wastewater moving efficiently
• protect infrastructure from pressure‑related wear
• reduce community odours
• support overall public health and safety

You may sometimes notice these vents along roads or near wastewater infrastructure, they are a normal and essential part of a well‑designed, modern wastewater network.
