Secondary Water Supply Quality Monitoring Solutions
With the rapid development of urbanization and the increasing number of high-rise buildings and high-rise centralized residential communities, how to solve the problem of water supply demand safely and efficiently has become a new problem facing the urban water supply system.
In order to standardize the requirements of the secondary water supply industry and ensure the safety of residents' water, relevant government departments have successively issued a series of industry supervision policies to strengthen the standardized management of secondary water supply and provide a good policy environment for the stable development of China's secondary water supply industry.
The limits of some indicators have been adjusted, including nitrate, turbidity, free chlorine, etc., the requirements for urban-rural integrated drinking water quality evaluation have been strengthened, and the management of the whole process from water source to faucet has been further strengthened.
"Technical Regulations for Secondary Water Supply Projects" - Ministry of Housing and Urban-Rural DevelopmentThe water quality of secondary water supply should comply with the provisions of the current national standard "Living Drinking Water Hygiene Standards" GB5749, and secondary water supply facilities should be equipped with online monitoring instruments for water quality such as residual chlorine (total chlorine), turbidity, and pH.
Notice on Strengthening the Leakage Control of Public Water Supply Networks – Ministry of Housing and Urban-Rural Development/National Development and Reform CommissionCarry out intelligent construction projects of water supply pipe networks, and monitor the operation status of water supply facilities and information such as water volume, water pressure, and water quality in real time.
"Notice on Strengthening the Security of Urban Water Supply" - Ministry of Housing and Urban-Rural Development / National Development and Reform Commission / National Bureau of Disease Control and PreventionStrengthen the monitoring of water supply quality, and organize and carry out full coverage inspections of key water quality indicators of factory water, pipe network water, and secondary water supply. From April 1, 2025, urban water supply will fully implement the "Living Drinking Water Hygiene Standards".
For the water quality monitoring in secondary water supply, has launched a secondary water supply water quality monitoring program, with the Internet of Things water quality sensing technology as the core, using big data information technology, through the construction of a real-time, remote and automatic secondary water supply water quality monitoring network, to achieve the goal of improving water quality optimization efficiency and real-time accurate data, and effectively ensuring the safety of residents' drinking water.
This solution uses multi-parameter water quality sensors, flow meters, liquid level gauges and other sensing equipment, combined with the intelligent information management platform, through automatic monitoring of changes in secondary water supply water quality parameters, can also support free selection of other parameters, through high-quality data transmission modules, upload water quality monitoring data to the platform, replace the cumbersome manual water quality recording and analysis, and establish a secondary water supply monitoring solution of real-time monitoring, remote supervision, inspection and maintenance.

In order to improve the secondary water supply system and ensure the safety of drinking water for residents, a community in Lanxi City, Zhejiang Province, decided to renovate the secondary water supply pumping room and use a number of advanced water quality monitoring and analysis instruments. After market research and comparison, it was finally decided to purchase the water quality online monitoring instrument of.
In order to solve the problem of secondary water supply water quality monitoring, the water quality monitoring point of the second supply pumping station has introduced the analysis instrument: online PH, turbidity, and residual chlorine three-parameter monitoring analyzer, which can quickly obtain various water quality indicators through online monitoring to ensure the daily water use of the community.
- This project purchased 15 sets of online monitoring systems for water quality of pipe networks
- Compared with other similar brands, the colorimetric method is more stable
- Easy to install, easy to maintain and clean
- Online monitoring and real-time alarm
