With an increasing population; urbanisation and deteriorating sanitation piping systems, the focus to improve our current sanitation systems is more important than ever in Kenya, East, and Central Africa. Double Walled Corrugated (DWC) piping system is set to revolutionise and provide a superior alternative to current solutions such as Concrete and / or uPVC.
DWC offers 3 main advantages:
- Technically superior
- a.)Higher corrosion and abrasion resistance
- b).Improved hydraulics
- c).Ability to deflect load, and transfer this to the surrounding soil, resulting in higher loading capability as a system than alternatives.
- 2. Longer lifetime
- a).Built to last for over 50 years
- b).Resilient and durable system, with high chemical resistance and impact
- 3. Economically superior
- a). Better value than the alternative
- b). Easier to transport
- c). Easier to install – lighter, stronger and no need for specialist equipment
Saniflex – the DWC system offered by DANCO, Kenya has already shown the system operating and improving lives in Kenya and other neighboring countries. Quality driven and with an eye on innovation, they have offered this solution to a number of projects with resounding success. Completed in 2021, Tilisi Development PLC is a perfect example. This is a 400-acreage, master-planned suburb that has been inspired by the vision of achieving a managed development in Kenya with world-class infrastructure, offering great accessibility, secure surroundings, and modern amenities.
The developer was therefore looking to ensure water supply to each parcel through Tilisi’s own water and sanitation system with high standard sewage treatment plants. The initial plan was to use concrete on sewers and this was abandoned in phase 2 of the project in January 2020 and Tilisi adopted the Danco Saniflex DWC Pipe due to it’s distinct features. Concrete required heavy machinery to install hence more costs on labour and transport, the short lengths of concrete meant more joints, and hence exposed to leakages, concrete is also easily corroded by the chemicals in the waste material.
