Midi tanks designed for small to medium storage requirements Developed by Structa Technology’s engineering team, the new Circotank range draws on vast experience gained in the design of industrial and petrochemical storage vessels and tanks.

The introduction of the Circotank series meets the growing demand for practical water storage solutions across a diverse user spectrum that includes commercial and industrial clients, agriculture, rural and peri-urban communities.

Manufactured from galvanised steel sheet cold-rolled with a stiffening profile, each tank comes equipped with a replaceable PVC liner for extended durability and reliability. Ease of shipment and installation is a further key feature of

these modular tanks, which are designed to be transported to the remotest sites in pre-rolled segments. Supported on a cast in situ concrete ring beam foundation, the tank is then erected using a simple strake lifting system, with full installation services provided by Structa’s specially trained teams.

Made to last

During research and development, Structa interrogated the Circotank’s design using finite element analysis techniques to check for collapse and other failure modes. Materials and joints were also thoroughly tested during the development phase to confirm overall durability, quality and reliability.

Midi and Maxi

Two product lines are fielded, namely the Maxi and the Midi. The Maxi range caters for large-scale water storage projects ranging from 100 000 up to 1.5 million litres. Typical applications here include industrial water storage, fire-fighting and potable bulk water supply schemes.

The Midi range is targeted at small to medium installations and fills a gap not covered by typical moulded plastic tanks. End-users encompass schools, clinics and small rural communities.

Midi storage capacities range from 5 000 to 20 000 litres and work optimally when placed on stands to provide distribution pressure. Both the tank and stand are supplied as an integrated system.

Local manufacture

The Circotank range is manufactured at Structa Technology’s Meyerton factory in

Gauteng, where the equipment used for the semi-automatic punching and profiling were custom developed. In-built flexibility within the industrial engineering process provides the capability needed to custombuild Midi or Maxi tanks according to the client’s requirements and conforming to Structa’s ISO 9001 quality system.

It is said the best inventions are the simplest. In Circotank’s case, that translates into an exceptional return on investment in terms of the total cost per cubic metre of water stored.
