We are for water for life.
As an on-site sanitation solutions company our core business is the provision of solutions to treat wastewater safely and effectively, for re-using purposes or to replenish aquifers. We protect a precious, life-giving resource and further advance water security in order to help safeguard the well-being of individuals, their communities, and the environment.
Our Heritage
Calcamite originated in 1967 as Telford Plumbers and Drain Layers, founded by Paddy Telford. One of its first projects was connecting Pretoria to the municipal sewer line, leading to the creation of Calcamite. The name, derived from the materials in a concrete pipe: calcareous material and dolomite, symbolises innovation and entrepreneurial spirit. Calcamite’s legacy is a testament to South African resilience and pioneering.
Ownership
In 2019, JoJo Tanks recognised the synergy that Calcamite offered to its mandate to transform into a water solutions company. Calcamite was subsequently acquired by JoJo Tanks. The manufacturing facility in Klerksoord, on the outskirts of Rosslyn, has been retained, while common corporate functions are being merged with JoJo. This integration ensures that the JoJo values are woven into the Calcamite business and brand.

Roto-moulding Capabilities
Calcamite stands alone as the only packaged wastewater treatment company possessing in-house expertise to roto-mould larger containers specifically designed for various sewage treatment applications.
The Process
Roto-moulding is a specialised production technique where a heated mould filled with plastic powder is used to create large plastic parts. By heating and slowly rotating the mould both vertically and horizontally, the resin is evenly distributed and fused to the inner surfaces of the mould.
These roto-moulded components are manufactured exclusively for Calcamite’s on-site wastewater treatment plants of different sizes. Assembled in Rosslyn, Pretoria, the only outsourced components are pumps, blowers, and Bio-reactor media, all sourced from local distributors.
The Material
Calcamite’s roto-moulded components are crafted from the highest quality LLDPE (linear low-density polyethylene), locally sourced from Sasol. This ensures the integrity and durability of our products.
The Benefits
Seamless Construction:
Our roto-moulding process produces watertight containers that are robust and corrosion-resistant, essential for preventing harmful sewage spillages.
Customisation:
Additional plastic can be added in high-stress areas to prevent buckling under water or soil pressure.
Cost-Effective:
When compared to conventional construction methods and imported alternatives, roto-moulding is a quick and cost-efficient production method.
Pan-African Reach:
Our unique capabilities enable us to service projects throughout Africa, extending our impact and commitment to water treatment solutions.
