Our History

HTC Group Fire

Keith Lees founded Hydraulic Testing and Certification in 2006 conducting water mains and fire hydrant flow and pressure testing for his own hydraulic consulting company. He started testing for his hydraulic consultant colleagues and continued to expand in the Sunshine Coast and Brisbane.

Dan purchased the business in 2015 with the aim to maintain Keith’s reputation in the industry. Since 2015, we have built a small but dedicated team that uses the most up to date technology and equipment to offer a consistent and high-quality service.

In 2018 we built a pump appliance to allow us to commission boosted fire hydrant systems. In 2022, Hydraulic Testing and Certification was rebranded to HTC Group as part of the introduction of fire protection services.

HTC Group believes in the small but valuable role we play in supporting our clients in all things relating to fire hydrants and reticulation mains.

Giving Back

HTC Group donates a small percentage of our profits to the Shantipara Association for Education in the remote town of Satkhira, Chittagong District in Bangladesh. The Shantipara Association for Education was established in 2009 and their first target was for “no child to miss Primary School (Grade 1 to 5)”.

That goal has now been achieved and 100% of the children in the area are completing Primary School. More exciting is that four students have graduated from college and two have returned to help teach the students.

Donations have contributed to a number of initiatives aimed at meet the needs of the community.

In 2016 and 2019, we donated books, bags and stationary to make educating that little bit easier.
From October 2019 until completion in March 2021, we have been constructing a third level on the school building for students to continue studying throughout the wet season.
In May of 2021, we donated sacks of rice, potatoes, lentils, onions and oil to help people living on the fringes meet their basic needs.
