People benefit

Recently, Mr. Tran Van Thanh (Ut Tich Street, Tan Binh District) no longer has to go to Tan Hoa Water Supply Joint Stock Company (District 5) to reflect the unstable situation in the process of using domestic water. Thanks to the smart water meter, his family knows the amount of water used every day. If the amount of water increases abnormally, the pre-installed software on the phone (directly connected to the water meter) will sound an alarm to the user. From there, his family can actively check the pipes as well as related equipment to find water leaks, and at the same time notify a technician to come and handle it. "For more than five months now, the monthly water bill has to be paid less, and the water usage is more economical," said Mr. Thanh excitedly.

As a place often lacks water, but so far the people of Nha Be district have benefited from a smart water supply system. Ms. Le Thi Xuyen (living on Nguyen Binh Street) said that every time there is a problem related to the water supply process such as water supply pipe tank, water leakage and problems related to the water supply process, All of her family have application software available on Smart phones to proactively notify Nha Be Water Supply Joint Stock Company and have it resolved quickly within a day. The city water industry has also used water meters to read numbers remotely to avoid trouble for each household.

Currently, Tan Hoa Water Supply Joint Stock Company provides safe water for production, business and daily life in two districts of Tan Binh and Tan Phu. Up to now, in the area managed by the company, 100% of households have used clean water. Deputy Director Tran Cong Le said that in the past, the reception, handling, monitoring and management of incident points on the water supply network were mainly manual, causing many difficulties and slow resolution. Overcoming the inadequacies, the company has researched the software "Troubleshooting on mobile phones and PCs".

This solution has helped Tan Hoa quickly record customer requests about the status and problems of water supply; collect information, location, image of incident test results at the scene by mobile phone, even when there is no 4G or phone signal... From there, it is possible to quickly fix the problem . The software also helps monitor the location and route of employees in the field through the employee monitoring interface right on the web or mobile device.

Also in charge of providing clean water to people in central districts, Cho Lon Water Supply Joint Stock Company is currently supplying clean water to people in districts 5, 6, 8 and Binh Tan. With more than 287 thousand water meters and 1,312 km of level 3 pipelines, these areas are densely populated, noisy and traffic is crowded, so leak detection has faced many difficulties in the past. According to Mr. Nguyen Anh Kiet, Deputy Technical Director of the company, in order to detect water leaks, workers must go through the pipes during the day to identify them and then make a small area to continue detecting at night. “The situation of water supply workers having to go down the drain for hours on end looking for water leaks is commonplace. However, the detection rate is also very low," said Mr. Kiet.

From the above difficulties, the company has applied the Chowagis program to manage the database of water supply network assets, information about tank detection, notification of water outage status to customers, and management of information about contracts. total pool (DMA) on computers and smartphones. The unit also applies the regional worker management model (Caretaker) to localize, set up and manage the operation of DMAs, to improve efficiency and reduce loss of revenue. As a result, 136 DMAs in the area were controlled with a rate of more than 90.84%.

According to Director of Ho Chi Minh City Department of Construction Le Hoa Binh, in the coming time, the Department will work with a group of foreign experts to study and rebuild the water supply planning. In addition, the department also inspects reservoirs, water pipes, and reviews water treatment and supply processes. The Department will apply technology to detect leaks and damage to water transmission pipes to reduce the rate of water loss.

Science and technology is the savior

Currently, Ho Chi Minh City's water source is exploited from two main sources, including: surface water accounts for about 95.2% (taken from Saigon and Dong Nai rivers), underground water source is about 4.8% (exploited from Dong Nai river). mining in District 12, Hoc Mon and Binh Chanh districts).

Regarding the implementation of modern scientific and technological applications in the production and supply of clean water to the people, Saigon Water Supply Corporation (Sawaco) informed that, over the years, the city's water industry has had many applications. successfully applied modern technological solutions and brought many benefits in life such as: Successfully converting to use liquid PAC (Poly Aluminum Chloride) as a coagulant to replace aluminum alum in water treatment; equipping factories with inverters to help adjust the operating mode of pumping stations flexibly to suit the requirements of the water supply network; successfully applied hydraulic software (WATERGEMs) to operation management and development of water supply systems. At the same time, the GIS (geographical information) system was deployed for the city's water supply network, contributing to improving the water supply management capacity, systematizing the database for the operation of the water supply system. country.

In particular, the water industry has successfully applied the construction solution to connect the water supply pipe with the technology of using the Linestop valve to relocate the water supply pipe. As a result, the construction process did not interrupt water supply activities as before.

In addition, Sawaco Deputy General Director Bui Thanh Giang said that smart management online monitoring devices have been piloted in some areas to monitor water quality continuously. This helps to control incidents such as pipe breakage, water pollution, and network operation effectively. The above applications and reforms bring about high efficiency, saving time, human resources and costs in operation...

Currently, the city's water sector is implementing the overall operation management of the water supply system according to the model of the Center for overall management and operation of modern water supply systems in the world in order to improve management capacity. operation and modernization of the water supply system. The infrastructure construction phase will invest in and integrate SCADA systems of water supply networks, SCADA systems of water plants, SAWAGIS systems, WATERGEMs hydraulic software, quality monitoring and monitoring systems. water as well as other components; at the same time prepare human resources to implement overall operation management in the future.

According to Mr. Le Hoa Binh, in the coming time, Ho Chi Minh City's water industry will continue to promote the application of information technology in association with reforming administrative procedures, simplifying documents; improve work processes, word processing; building and developing new functions for the electronic office such as task management, project management... The goal by 2025, the city will manage and operate the water supply system in the direction of automation, modernization.

According to Vice Chairman of Ho Chi Minh City People's Committee Vo Van Hoan, the water supply planning needs to be reviewed, adjusted or made a new one, becoming urgent. City water supply planning must be associated with regional water supply planning. When planning, must pay attention to water security and pay attention to the economical use of water, efficient water supply for people and businesses.
