Water storage facilities company Rainbow Reservoirs reports that it has received enquiries from contractors working on several significant construction projects for relocatable water storage reservoirs of a similar capacity to those that the company previously supplied for the construction of the Gautrain, at the Rosebank site.
The Rosebank reservoir stores 153 000 ℓ of water. The construction site required that the storage tank have the option of repeated tank relocation.
“Almost all other locally available reservoirs of 400 000 ℓ or smaller require either a concrete base poured as a foundation for the walls, or poured across the reservoir’s entire base area,” explains Rainbow Reservoirs MD Wayne Thompson.
“This makes disassembly and relocation difficult, whereas the Rainbow product needs only a sand base. “This means it also leaves no environ-mental footprint after removal,” says Thompson.
Above 400 000 ℓ, a concrete founda-tion of some kind becomes necessary for all reservoirs.
The Rainbow Reservoir range comprises climateproof, steel-walled, panel-type designs compliant with international standards and available in capacities of 52 000 ℓ to two-million litres.
The Polokwane-based company reports that the life expectancy for reservoirs across the range is some 40 years without the need for any concrete foundation, making them ideal for installations requiring relocation.
Suitable for a variety of applications, the Rainbow product is characterised by a simple and robust structure that is easy to erect and easy to transport, says Thompson.
An integral, low-profile roof adds strength and prevents contamination.
Corrosion-resistant steel walls are internally lined with a food-grade liner to prevent contamination of the stored liquid, which can be anything except corrosive chemicals.
A fire outlet fitting makes the range suitable for use in fire hydrant installations.
Thompson is committed to rural devel-opment in Polokwane, and is interested in rainwater harvesting. Rainbow Reservoirs has supplied its water storage facilities to rural communities to promote healthy and safe water storage and use.
He explains that the local community has difficulty accessing water and currently uses handpumps to obtain water from boreholes, which proves taxing. Further, the groundwater is becoming increasingly polluted, especially with the poor housing systems and the prevalence of slums in South Africa.
Therefore, Thompson says, the company’s storage products could assist in the fight against waterborne diseases.
This all depends on the authorities’ willingness to embrace this system. He says that the facilities have achieved significant status in Australia, where a sister company supplies mores than 100 tanks, especially in the farming areas.
