Vietnam: To meet the increasing needs for water supply, an extensive expansion project was initiated in Da Nang City. The project is a national key project and is part of an overarching plan in Da Nang’s overall development.
The Hoa Lien water treatment plant is the largest plant in Da Nang, an important port city on the Eastern coast of Vietnam. To meet increasing water needs as a result of an ongoing rise in population as well as growing production and tourism sectors, it was planned to expand the plant’s capacity.
10.6 km of raw water pipeline
The expansion of the Hoa Lien plant features the construction of a spillway on the Cu De River to source water, with a 727m² raw water pumping station, with a daily capacity of 120,000m³ as well as DN1400 raw water pipelines. In a following phase 2, the plant is capable of upgrading to 240,000m³ of water.
A 1.4 m diameter and 10.6 km long raw water pipeline will be placed underground, running from the pumping station in Hoa Bac Community’s Nam My Village to the water treatment plant in Hoa Lien Community’s Quan Nam 1 Village. Ultimately, the expanded project will help to increase the capacity of water supply for residents of Da Nang city.
With the support of other AVK Group companies such as AVK International A/S, AVK Polska, Wouter Witzel Eurovalve and AC.MO S.r.l., AVK Vietnam and Hawaco put together an ideal solution for the project. Our valves meet the strict technical specifications of the installation and can ensure quality in coastal climates and potentially saline water sources.
Drinking water certifications were essential
An important factor in the product evaluation process that turned out to be our valves’ many certifications for drinking water by independent international organisations such as WRAS, DVGW and KIWA. The project stakeholders were completely assured with our products’ quality in meeting optimal operation cost, minimising water loss, and can rest assured that the water quality is kept safe for the residents and tourists in Da Nang city.
Complex installation
The dam had to be constructed between two rainy seasons in a very complex terrain. Therefore, to ensure the safety of the project, adjusting to the downstream is an extremely important matter. The construction of a raw water pipeline in a mountainous terrain entails many difficulties in the transportation of machinery, materials, and workers. AVK and Hawaco have been happy to support this important project in Vietnam.
