An emergency solution by HST and KSB following the collapse of an embankment on the Irrawaddy River proved so successful it will be used for other flood control systems, improving the health and safety of residents in Mandalay, Myanmar.
The land on the eastern bank of the Irrawaddy River (also known as the Ayeyarwady River) where the City of Mandalay is situated is low and prone to heavy flooding into the residentail parts of the city. The area is in need of a proper flood control system and infrastructure.
Naturally, the overflow of flood water into these areas causes great inconvenience and discomfort to the residents who are deeply concerned about the adverse effects on their health brought about by direct contact with the flood waters or indirectly from damage to infrastructure, ecosystems, food and water supplies, and social support systems.
The flow of water becomes worse during the wet season running from May through to October as heavy rainfall causes rivers to rise. In 2019, several states and regions in Myanmar were hit by heavy monsoon rainfall and flooding from mid-July that started in the Kachin and Rakhine states and the Sagaing Region.
The United Nations report stated that over 40,000 people were displaced by the monsoon flooding by the end of that month and stayed in 186 evacuation centres in Kachin, Rakhine, Chin, and Mon states, as well as Bago, Sagaing, Mandalay and Magway regions. By early August, more than 89,000 people across nine states and regions were displaced by the monsoon flooding; the country needed a well-established drainage and flood control system.
In July 2020, an embankment along the Irrawaddy River collapsed and flood control became an even greater concern for the authorities. The water from the swelling river leaked through the soil and the weakened embankment could not hold the pressure. The collapse resulted in a flood that destroyed the roads near the embankment and affected lowland areas.
More than 12,000 residents had to leave their homes. The authorities sought the technical and service support of pump distributor Han Sein Thant Engineering (HST) to help drain out the water at the collapsed embankment while fixing the damage and taking care of the welfare of the residents who lost their homes.
Due to the emergency and severity of the situation, the authorities could not allow much time for the construction of the usual concrete flood control structures to install the pumps. Mr James U Thant Zin, the managing director of HST, planned the standing support design with mobile pipelines as an immediate solution to address the situation. Since the standing support design was mobile,…
