Keeping millions of feet dry by intelligent dewatering

A new tourist area in Tianjin, China, lies below sea level. In order to avoid flooding within the reclaimed area huge pumps have been installed to lead rainwater out into the sea. This task is handled by the largest prefabricated pumping station from Grundfos.

The Water Magic Cube is the name of one of the attractions at the Binhai Tourist Area in Tianjin east of Beijing. In the water park, it is important that water is kept at the attractions, not around them. To achieve this, a Grundfos solution keeps the tourists’ feet dry in the park and its surroundings. A solution that is able to handle as much as 3,000 litres of water every second and collect water from an area of one square kilometre.

President Zhang Jiguang from Tianjin Binhai Tourism Area Investment Holding Co., Ltd, explains the choice of solution – the largest prefabricated pumping station in the world from Grundfos.

“We chose this solution because of its advanced technology. Automated draining, a modest space requirement, and energy consumption 15 per cent lower than for systems produced in China, were crucial”, he says.

The pumping station was delivered as a turnkey product, ready to use. It came fully equipped with pumps, tanks, pipes, and valves. Built-in control units makes the solution intelligent and energy saving by varying its performance according to the specific need.

Big potential
According to Zhang Jiguang, the pumping station marks only a start for Grundfos doing business in the area.

“We are certain that we can get even more from this good cooperation in the future, Zhang Jiguang foresees.

“It is not part of our tradition to work in this way with water transport, but I believe this market can be highly developed in China. That is why we want to gain an insight into advanced technology from other countries and to collaborate with Grundfos on developing innovative solutions, setting new standards for water handling.”

Small inconveniences
According to Jason Dang, senior sales manager for Grundfos in northern China, the Grundfos solution is particularly suitable for large cities, because installation inconveniences are much smaller than for other pumping stations.

“Prefabricated pumping stations can be established with a minimum of impact on the surrounding facilities within only one month, while it takes three to five months to establish a conventional pumping station on the spot. And as everything is tested before leaving the factory, the risk of errors is minimized,” explains Jason Dang.

He notes that the interest in intelligent prefabricated pumping stations is growing in China, for instance spurred on by heavy rainfalls and flooding in major cities in recent years.

“As the advanced technology contributes to minimizing the consequences of extreme weather conditions and at the same time saves energy, the market is gigantic”, he says.
