Concrete Water Tanks – SMC Panel Alternative for Concrete Tank Replacement

Concrete Water Tanks and Their Modern Replacement

Reinforced concrete has been the default material for large water storage for most of the last century, and concrete reservoirs are still common in municipal infrastructure. For building-level and commercial storage, however, the disadvantages are becoming harder to justify.

A concrete tank has to be built in place: formwork, reinforcement, pouring and a curing period of at least 28 days before water can be introduced. For potable water it must be finished with a food-grade coating or membrane, because unlined concrete leaches lime and supports biofilm growth. Cracks and liner failures are the most common problems in ageing concrete tanks, and repairing them means draining the tank, surface preparation and re-lining it – a slow and expensive operation.

An SMC panel water tank delivers the same storage function without any of that. It arrives as finished panels with a moulded, non-porous water-contact surface, is assembled in days rather than weeks, and requires no curing and no lining. Below about 1,000 m3, a sectional tank almost always offers a lower total installed cost and a much faster commissioning timeline than an equivalent concrete structure.

• Assembled in days, with no curing period before filling
• Moulded water-contact surface, no food-grade lining to fail
• Does not crack, spall or suffer reinforcement corrosion
• Lighter structural load than a concrete tank of the same volume
• Can be installed inside an existing concrete chamber during refurbishment
• Individual panels replaceable without demolishing the tank

Applications

• Replacing ageing concrete water tanks in commercial buildings
• New build potable water storage where concrete would need lining
• Rooftop storage where concrete structural load is unacceptable
• Plant room and basement installations with restricted access
• Municipal and industrial storage below roughly 1,000 m3
