The Brighton Main Sewer is over 100 years old and was one of the original sewers built in metropolitan Melbourne. Melbourne Water undertook upgrades to ensure the Brighton and Hampton areas continue to receive a reliable sewerage service. The key Melbourne Water driver for this project was the rating risk of the asset due to a breakdown of the conditions of the brick sewer. An upgrade was required to avoid the risk of asset failure and further degradation. The Brighton Main Sewer is in an area of significant community amenity and is home of one of the world’s busiest road bike circuits with more than 15,000 cyclists riding on Beach Road every week. The sewer is also very close to Port Phillip Bay. The sewer services the local Bayside community ensuring that the marine and coastal environment are protected.
