Tomorrow’s Technology for Today’s Liquid Storage Needs

REL Group have launched their range of Effluent Tanks for the Agricultural Industry and Water Tanks for the Construction and Agricultural Industries.


Construction Industry Water Tanks:
REL Group have partnered with a European Supplier to fabricate robust, technologically advanced, environmentally sustainable water storage tanks for the Construction Industry in New Zealand, Australia and the Pacific Islands.

 We have recently completed the Christchurch Hospital’s Acute Services Potable Water reticulation project in conjunction with the Governments Head Contractor, CPB. 8 x 25,000 Litre Modular Bolt together, 316 Stainless Steel Tanks were designed to fit into the ground floor plumbing facility which is providing fresh potable water to all parts of the Acute Services Building. Importance Level 4 Seismic Bracing was utilized to ensure integrity of the tanks during seismic events.


Final fabrication of a 40,000 Litre, 316 Stainless Steel Modular Tank is taking place currently for the new Christchurch Convention Centre with Importance Level 3 Seismic Bracing. Installation due October 2019.


Other exciting Construction Industry projects in the future include swimming facilities, convention centres, prisons and hospitals.
