Textum Roofing has been trusted by PowerWater to deliver a series of critical infrastructure upgrades across the Northern Territory. Working on live treatment plants, remote regional facilities and elevated water tanks serving entire communities, each project demanded the highest levels of programme discipline, safety management and coordination with PowerWater operations staff. From Darwin to Katherine and beyond, our team consistently delivered complex refurbishment works on time and to specification — ensuring minimal disruption to essential water services throughout. Below is a 3 of the projects completed with another 4 tanks also delivered over a number of years
Ludmilla Wastewater Treatment Plant Upgrade
Project Scope:
- 1,350m² Roof Sheeting
- 145m² Soffit Linings
- 400m² Wall Cladding
- 2,500LM Roof Purlins & Wall Girts
This refurbishment involved the full removal and replacement of existing roof sheeting, wall cladding and structural purlins. As a live, operational facility, works were carefully sequenced to ensure zero disruption to the plant’s day-to-day operations. Daily coordination with PowerWater staff was essential to maintaining both project momentum and continuous plant functionality throughout the programme.
Katherine 9ML Water Tank — Roof Replacement
Project Scope:
- 5-Month Programme
- 2 Months Procurement
- 3 Months Installation
With the tank taken offline for the duration of works, on-time delivery was critical to the town’s water supply. The scope included full removal of existing roof sheeting and perimeter handrail, removal and transport of all structural steel to Darwin for blast cleaning and re-galvanising, before being returned to Katherine for reinstallation. New stepped aluminium roof purlins were fabricated to suit the tank’s triangular sections, with LT7 Permalite Aluminium Roof Sheeting, new aluminium perimeter handrails and internal stainless steel stairs all installed as part of the refurbishment. Managing long material lead times, a remote location and wet season conditions — including extreme heat and rainfall from February onward — required careful forward planning and programme discipline.
Salonika Elevated Water Tank — Roof Replacement
Project Scope:
3-Month Programme
