Major sewer improvements for Kampala, Uganda
In Kampala City, a major improvement program for its urban sewer network was undertaken, with aid of the German government. The project spanned rehabilitation, modification and extension of the existing sewer network together with the construction of a new combined sludge and wastewater treatment plant at Lubigi.
The final 5.2 kilometre section of the new sewer network posed particular challenges. The route passed through swampy waterlogged ground, with very high groundwater tables. The sewer would need to carry high volumes of corrosive waste to the new treatment plant.
The civil engineering team wanted pipes that would resist corrosion, that were chemically inert, and were exceptionally robust. Their preferred polypropylene double wall corrugated pipes would need to conform to the EN 13476 standard.
Wavin X-Stream complied with the contract’s specifications and these polypropylene, double-wall, corrugated sewer pipes would be deployed in diameters of 400, 500 and 600 mm.
Wavin Overseas provided an extensive series of support services to ensure that the pipeline would be laid right-first-time.Spencon , contractor
Wavin Overseas provided:
- On-site practical installation guidance
- Product training on storage, handling, installation and testing
- Factory visits and demonstrations showing quality assurance and product testing
For contractor Spencon, the product excellence combined with the extensive training by Wavin Overseas was very important and certainly helped completing the project to the highest standards.
PVC PressureWavin offers a full range of PVC-U and PVC-O pressure pipes (diameters ranging from 50 to 630 mm) in various pressure classes, for use in sewer systems. All the pipes, with their respective fittings, are easy to install and durable.
PVC Main sewerWhen a high dimensional, stable and a smooth wall (in and outside) pipe is preferred, Wavin has a PVC multi-layer pipe available. The pipe makes use of recycled material in the core of the pipe wall. It therefore has the highest environmental credentials.
