Practical, plain-language guidance on choosing, installing and maintaining water storage, written by the Promax team.
From a 2,000L trailer to 15,000L chassis-mounted builds, here's how the NZ-made Promax dust suppression range keeps civil, forestry and roading sites safe, compliant and working.
Read the guideIndustrial storage is about more than litres. Here's when a standard water tank stops being enough, and what NZ businesses should weigh up for wastewater buffering, process water, fittings and seismic requirements.
Read the guideTank size is only the start. Here's what NZ civil, quarry, forestry and roading operators should check before buying a dust suppression unit: pump performance, baffling, build quality, vehicle fit and more.
Read the guideDenser sections, tighter rules, less outdoor space. Slimline tanks let new builds hit rainwater and stormwater requirements without giving up the yard.
Read the guideSpring is the turning point for a rural water system: winter has tested it, and summer demand is coming. Here's what New Zealand farmers should check and get right now.
Read the guideUnderground tanks free up land, stay out of sight, and keep the surface above them usable. Here's when they make more sense than an above-ground tank on a New Zealand property.
Read the guideSeptic planning is often left until late in a build, and that costs time and money. Here's what NZ homeowners and builders should weigh up before choosing a system: sizing, site conditions, and council requirements.
Read the guideGroundwater around an empty underground tank can compress its walls until they collapse inward. Here is how hydrostatic crush works, how it differs from flotation, and the two ways to design it out.
Read the guideGreywater reuse puts water back into jobs that never needed drinking quality in the first place: toilet flushing, laundry and irrigation. Here is what it saves, and where a Slimline tank with a built-in pump and changeover device fits.
Read the guideGround movement is not only an earthquake problem. In Auckland, where seismic activity is low but the clay is highly expansive, the soil moves with every wet and dry cycle. What that means for leak risk, B2 durability, liability and repair in integrated water systems.
Read the guideCouncil stormwater rules differ from region to region, so the tank you need depends on which rule applies to your site. Promax detention tanks and sizing calculators take the guesswork out of the number.
Read the guideFour accessories keep rainwater clean in two stages: filtering debris before it reaches the tank, then drawing from the cleanest layer inside it. Here is what each one does, and which pair matters most.
