Automated Anti-Vandal Series
Dinah Beach Darwin
A three booth Automated Anti-Vandal Series restroom at Dinah Beach Boat Ramp in Darwin. The building feature automatic self-cleaning, automatic night locking, audio notifications and usage data logging.
Pureablue was awarded a contract to design and construct a three booth toilet facility with associated civil, sewer, water and electrical works.

The project was a response to community request for modern toilet facilities at a popular boat ramp not far from city centre. The site was adjacent to a high density residential precinct, adjacent to environmentally sensitive mangroves and subject to normal urban area high use and vandal susceptibility.

The Pureablue proposal was chosen over a locally designed masonary block building, of very traditional design, with very little empathy to nearby residents outlook and amenity. Pureablue worked with DIPL in the project specification build, allowing for marine environment (salty atmosphere), auto-cleaning capacity, engineering design to cater for cyclone wind loads and predictable king tide events.

Pureablue’s team of design professionals and structural, civil, and electro-mechanical engineering associates were involved in the facility and system design featuring the Pureablue stainless + concrete R panels in 316 stainless steel , hot dipped galvanised steel structure with high build protective paint system, auto clean system with PLC management system including remote connectivity for system surveillance and fault diagnosis capability.

Sewer drainage works presented engineering challenges to Pureablue as the site contained a cocktail of unknown fill material from unsupervised land fill practices for land reclaimation dating back many years, potential acid soils and mangrove silts. Further complications was the necessity to placate noise concerns on the adjacent residents, minimisation of potential interruption to an adjacent retail business accessway and extreme environmental management requirements. The sewer system eventually developed into a rising main system.

The electrical system includes self-cleaning operation and night time automatic locking, for example, facility locks at 7pm and re-opens at 6am. If the doors do not successfully lock and close (ie there is an obstruction or interference) then a SMS message is sent to the facility manager. The locking system has functionality for emergency services to open the doors in a medical incident. And full system control is available via remote login.

The project was also delivered with political timeline pressure over the Christmas wet season. We are still drying out our boots.
