Water authorities have the critical role of maintaining our potable water, recycled water, sewerage and trade waste infrastructure. Residents and businesses rely on these services being functional to prevent hygiene issues and to ensure their sewerage system is orderly.

TDG provide services to water authorities to ensure the network is functional, assessed and maintained to prevent issues from arising. Some of the key services we provide to this industry are outlined below.

• Industrial Vacuum Loading and STP Maintenance Works: TDG has the capabilities to clean and maintain stormwater retention/detention pits, basin, pump wet wells, tanks, ponds and vessels.
• Cleaning and Maintenance of GPT & SPS: Over time, trapped waste accumulates and can lead to blockages, reduced flow capacity, and potential flooding during heavy rain events. Therefore, cleaning GPTs and SPSs are a critical aspect in stormwater management solutions for the sewer and water authorities industry.
• Bulk Liquid Transport: We use specialised waste vehicles purpose-built to transport substantial volumes of waste efficiently and safely. This can include stormwater, grease traps, sewer, oily waters, industrial wash-waters, and more. This helps prevent further issues to our sewer systems.
• Pits, Pipe and Culvert Cleaning: Cleaning and maintenance of pits, pipe and culverts are essential to ensure smooth water flow and prevent blockages or flooding to this industry.
