Efforts to provide clean water in the summer

(Baonghean) - In the situation of prolonged hot weather greatly affecting the supply of raw water for the operation of the water plant, Nghe An Water Supply One Member Co., Ltd. has applied many solutions to ensure enough water to serve the clean water needs of people during these summer months.

The raw water source for Hung Vinh Water Plant - Vinh City is mainly exploited from Dao River - Nam Dan. However, the recent prolonged dry weather has greatly affected the water source of Dao River. From May to now, there have been many times when the water level of Dao River (at Cau Muou) has dropped to -0.3m compared to the designed low water level. Faced with this reality, Nghe An Water Supply One Member Co., Ltd. has dredged mud, cleared the flow at the raw water collection pits of Cau Muou and Cau Duoc Water Pumping Stations, and reinforced the barrier system and prevented oil and grease from being discharged by ships on the river.

Mr. Le Duc Thang, Deputy Director of Hung Vinh Water Plant said: “To meet the raw water supply for the Plant's operation, every day Cau Muou and Cau Duoc Pumping Stations must supply more than 60,000 m3 of raw water/day. Due to the depletion of water sources in the rivers, we have renovated the suction lines of the pumps such as connecting an additional 30 cm of pipeline to the suction lines of 4 raw water collection pits at Cau Muou, thereby maximizing the suction capacity of the raw water pumps when the river water level is low”.

Operation of Cau Muou - Nam Dan raw water pumping station.

Cau Muou Pumping Station is the place where raw water is exploited from the source to serve Hung Vinh Water Plant, so the protection of water sources is of great concern to relevant levels and sectors. The unit, together with local authorities in Nam Dan and Hung Nguyen districts, regularly organizes propaganda sessions, mobilizing people not to litter indiscriminately into the river, to join hands in protecting water sources and to place warning signs in the raw water intake area.

Mr. Pham Viet Phung, Head of Cau Muoi Pumping Station, said: “In the past time, the local government and people have coordinated very well in protecting water resources and limiting the situation of people littering in the river, contributing positively to ensuring water resources. Currently, due to low river water levels, the station always has to adjust the pumping mode to suit the situation of depleted water levels. With these practical actions, Cau Muoi Pumping Station promptly provides raw water for Hung Vinh Water Plant to operate.”

In order to promptly meet customers' water needs in the summer, along with efforts to exploit and ensure raw water sources for the factory to operate, Nghe An Water Supply One Member Co., Ltd. also developed a plan to provide clean water to people, which is to increase the water supply operating time, ensuring water supply 24 hours a day. Regulate water supply zones appropriately to ensure uniform water supply in all areas. Organize a shift-based production department, receive information, and handle incidents related to the water supply system, including holidays and weekends. Deploy mobile booster pump clusters to increase water pressure for suburban areas far from the water plant such as Hung Loc, Hung Dung, Trung Do... invest in installing additional local booster pump stations on Nguyen Duy Trinh Street, Hung Dung Ward.

Despite many efforts to promptly meet the people's need for clean water (currently there are more than 70,000 customers in Vinh City and surrounding areas using clean water), in recent times, at some locations in Vinh City such as Xuan Bac, Xuan Nam blocks, Hung Dung ward, Ben Thuy ward, Trung Do ward, there has been a local water shortage and the unit has applied a method of timely water supply by specialized water tankers and has been highly appreciated by the people.

One of the highly effective activities in management and operation, especially water supply in the summer of Nghe An Water Supply One Member Co., Ltd. is the successful application of the Scanda management system using high technology with modern computer equipment, helping the unit monitor water pressure on the entire water supply pipeline network, thereby proactively regulating and providing timely water to customers in the area. Great support for timely water supply for customers this summer is the water supply project in the vicinity of Vinh and the industrial parks that has been completed and put into operation (in Nam Dan).

Currently, with the connection and connection of water from Cau Bach Water Plant (water supply project in Vinh vicinity and industrial parks), 500 - 600 m3 of water is supplied daily to the Northeast area of ​​Vinh City. An issue that Nghe An Water Supply One Member Co., Ltd. is very concerned about is monitoring water quality from the source to the customer. Currently, the company has invested in building a laboratory with modern equipment that can test 15 indicators (criterion A) and monitor and check the quality of water after treatment 24/24h. At the same time, it coordinates with the Provincial Center for Preventive Medicine to regularly take water samples for testing, thereby managing and adjusting the quality of clean water...

This summer, the unit pays great attention to ensuring the quality of domestic water and, along with strengthening industrial hygiene such as: Flushing the ditch and trough system, discharging mud according to regulations, and adjusting to increase preliminary chlorination before putting raw water into treatment (to increase safety in disinfection, treatment of organic compounds, odors, etc.).

Also to ensure clean water quality, recently Hung Vinh Water Plant has boldly used PAC water treatment chemicals to replace traditional alum. This method increases the cost, but ensures the stability of clean water quality for people.

In order to facilitate investment projects according to the province's policy of promoting and attracting investment, Nghe An Water Supply One Member Co., Ltd. has recently signed a contract in principle to use raw water sources invested by Tuan Loc Construction Joint Stock Company in a raw water system that takes water directly from Lam River in 2016. Thus, with a stable and high-quality raw water supply, it will greatly support the unit in performing well the task of providing clean water to the people of Vinh City and surrounding areas, and industrial parks.
