The whole flushing water system consists of 35 pumping stations, 54 service reservoirs with a total storage capacity of nearly 0.26 million m 3 and 1,800 km of water mains.
A process, through which flushing takes place under a. pressurized condition while the water level in reservoir remain. unchanged approximately, is called pressure flushing. This is. only an
WSD successfully extended the coverage of the seawater supply network for flushing from below 80% to 85% of the population for further reduction of fresh water demand. At present, seawater flushing has been available to buildings in Northwest New Territories (including Tuen Mun East, Hung Shui Kiu, Tin Shui Wai and Yuen Long Town Centre) and
The flushing of toilets generates contaminated aerosols, the transmission of which may cause the spread of disease, particularly in the immunocompromised or the elderly. This study investigated the emission strength of three types of airborne bacteria, namely Staphylococcus epidermidis, Escherichia coli, and Pseudomonas alcaligenes,

Step 6: Rinse With Water. After the vinegar solution has circulated for the desired length of time, it''s time to rinse the tankless water heater with water. Disconnect the pump and close the cold water inlet valve. Attach a new hose to the hot water outlet valve and place the other end of the hose into a drain or bucket.
Water storage. Water storage is a broad term referring to storage of both potable water for consumption, and non potable water for use in agriculture. In both developing countries and some developed countries found in tropical climates, there is a need to store potable drinking water during the dry season. In agriculture water storage, water is

Objectives: The water storage tank is fit and safe for the storage of water for human consumption. The water contained in the water storage tank is free from contamination or pollution. Water samples taken from the water storage tanks pass the appropriate chemical and bacteriological examinations. The water storage tank is
Seawater has been used for flushing in Hong Kong since the 1950s. Over the years, the Water Supplies Department (WSD) has been progressively extending the seawater supply network to conserve precious fresh water, i.e., potable water resources. In general, the WSD only approves the use of fresh water for flushing in

Internal water storage (IWS) is a GSI design element that can be incorporated to provide additional storage or promote denitrification. When anoxic conditions are present, NO 3 − is reduced to N 2 gas via microbial denitrification (Kim et al., 2003).
Remove any debris or sediment from the tank. Use a high-pressure water jet to clean the walls and floor of the tank. Disinfect the tank using an approved chemical such as chlorine or hydrogen peroxide. Flush the tank with clean water to remove any residual chemicals. Refill the tank with clean water.
Automatic flushing. One solution to reduce the risk of waterborne illnesses, which is quick and simple to install and will protect facilities in the long term, is an automatic one such as the Hydro-Guard Industrial Flushing System. This ensures water is pushed through the system at a sufficiently high velocity to eliminate stagnant water.
In this type of flushing, a great amount of water is released from the bottom outlets but a little effect occurs in restoring the reservoir active storage (Jansson and Erlingsson 2000).
WSD also target at expanding the network coverage of using seawater and recycled water for flushing from 85% of the total population to 90% in the long run in order to further
Step 7: Rinse and Refill the Tank. After you have added the vinegar or hydrogen peroxide, turn off the cold water supply and let it sit for at least 6 hours to allow the solution to dissolve the mineral buildup. After 6 hours, drain the tank and rinse it thoroughly with fresh water. Close the drain valve and refill the tank before turning on

Toilet flush power is crucial for effective waste removal, preventing clogs, and maintaining hygiene. Inadequate flush power can result in frequent clogs, which lead to expensive plumbing repairs. Poor flushing can also cause unpleasant odors and unsanitary conditions, Spreading germs and bacteria throughout the bathroom.

Flushing water demands are transient and influenced by occupant load variations, occupant usage patterns, installed appliances and system commissioning.
In 2020-21, the total operating and administration expenses (including depreciation but excluding staff cost) related to flushing water supply was about $976 million. The seawater supply network for flushing currently covers about 85% of the population in Hong Kong. WSD targets at expanding the network coverage of using lower grade water.
