The town of Shimla in the Indian Himalayas is one of the country’s busiest tourist destinations. It receives 3.6 million visitors a year, significantly augmenting the local population of three million. Known as the Queen of Hills, Shimla has experienced an acute water crisis as its popularity increased.

The Himachal Pradesh Jal Shakti Vibhag (formerly known as IPHD) has thus developed a plan to modernize the existing lift water supply plan with construction and upgrading of old pumps to raise water from the Kol Dam on the Satluj River thousands of feet below the city. The aim was to bring safe, clean drinking water to the population with minimal water loss and minimal environmental damage.

“With smart technology and our state-of-the-art products and solutions, ABB electrification products are helping residents of Shimla to get an uninterrupted supply of water,“ said C. P. Vyas, president of the electrification business for ABB India. “ABB‘s Softstarter device ensures smooth water movement while torque control minimizes leakage and pipe damage, eliminating pressure surges. With leakages being an important area of concern for the water industry, we are proud to set a benchmark for electrification technologies that help solve critical challenges,” he added.

While demand has grown every year, the aged water infrastructure has been losing 20-25% of the total water supply to leakage. Aggravating the problem, no major body of water is available in the vicinity of the main city, and the area’s steeply sloping landscape allows rainwater to run off quickly.

For some pumping stations, the IPHD was having problems of water hammering when stopping pumps and frequent blown fuses caused by current spike. To avoid such issues, IPHD decided to install eight ABB PSTX Softstarters for the Shimla project. IPHD had a sizeable installation of ABB Softstarters in other water supply systems and had been satisfied with their performance, easy handling and ease of use.

The IPHD now estimates that, with reduced mechanical wear and 30 percent fewer service calls, PSTX Softstarters can cut pipeline damage by up to 50 percent during starting and stopping operations, leading to overall cost savings.

The Shimla installation project had a very ambitious completion deadline, but ABB was able to meet the customer’s expectations, supplying the Softstarters on time. As a result of the customer’s confidence, S B Trading, is now commissioning several orders with ABB to ensure safe, smart and sustainable water in the region.
