  • flash floods

​​​​​​​A Dar es Salaam-based company—Plasco Limited has developed new technology aimed at addressing frequent floods in the metropolitan city.

Addressing journalists in Dar es Salaam yesterday Plasco Limited chief operating officer, Alimiya Osman said that the new technology provides solutions to city dwellers who face challenges whenever it rains as it makes almost all roads impassable.

According to him, the technology involve the use of weholite pipes, which proved to be lightweight, large diameter and made from high density polyethylene (HDPE) and they are used in low pressure and gravity applications for storm water management, sewage treatment systems, culverts, marine pipelines and irrigation water distribution.

“So, the use of weholite pipes, the problem could be avoided, and in doing so, living standards could be raised for generations to come,” he said. Weholite Pipe is a large diameter, flexible, lightweight and durable structured wall pipe made from High-Density Polyethylene (HDPE) resin.

He described the technology as unique and far better option for urban flood management.

“The pipes are available in sizes up to 2200mm internal diameter which makes it ideal for carrying large volumes of water away from troubled areas thus providing much needed relief to the residents,” said Osman.

The expert noted that other exceptional qualities of Weholite includes provision of a value engineering proposition which far exceeds that of concrete pipes.

Othman added: “Weholite pipes are durable and have load bearing properties; all these qualities make it the best solution for stormwater management. To put things into perspective, most of the current drainage systems are outdated and becoming overwhelmed by the current demand for evacuation of storm water, but with the new technology we can design systems that will provide solutions for the next 100 years.”

The firm has been working with Tanzanian municipalities and the private sector through various construction companies providing weholite pipe solutions in different construction projects, one of which is the storm water drainage line for the Julius Nyerere International Airport (JNIA) Terminal III project in Dar es Salaam. According to the engineers of the main contractor for the project, BAM International, Weholite’s innovative technology enabled a speedy and cost effective installation amid the rainy season.

Weholite systems are a new, innovative pipe solution which can bring great value to the residents of Dar es Salaam as it is locally manufactured and a proven technology which has been used in South Africa, Europe, North America and now, in Tanzania.

Plasco Limited is committed to deliver innovative and sustainable results and solutions to its stakeholders by manufacturing and supplying reliable plastic piping systems within Tanzania and neighbouring countries.

The Weholite technology was developed in 1983 and since then it has provided great value to the construction industry.
