Advisory Committee on Water Supplies fully supports Hong Kong's First Five-Year Plan to develop Hong Kong into international hub for high-quality development of country's water sector
The following is issued on behalf of the Advisory Committee on Water Supplies:
The Advisory Committee on Water Supplies (ACWS) discussed at its meeting today (October 9) the major policy strategies and initiatives relating to water development set out in the First Five-Year Plan for Economic and Social Development of the Hong Kong Special Administrative Region (2026-2030) (Hong Kong's Five-Year Plan) and the Chief Executive's 2026 Policy Address. Members unanimously expressed support for the relevant strategies and initiatives.
The ACWS is pleased to note the Government's commitment to developing Hong Kong into an international hub for high-quality development of the country's water sector, developing advanced standards for water-related affairs applicable to the Guangdong-Hong Kong-Macao Greater Bay Area, and capitalising on Hong Kong as an international demonstration platform for Mainland water-related technologies, where pilot testing, transformation and application can be conducted. These initiatives will assist technologies and enterprises of the Mainland and Hong Kong in going global and provide the international water sector with high-quality and cost-effective water solutions. At the meeting, members offered suggestions to the Government on the relevant strategies and initiatives.
The Chairman of the ACWS, Mr Edmund Leung, said, "The Water Supplies Department (WSD) and the Drainage Services Department will jointly organise the inaugural Hong Kong Water Expo in April next year. The event will provide a new high-level platform for exchanges among water professionals around the world, promoting the close integration of strategic thinking, research and development achievements, and practical applications. It will also facilitate water-related technologies and enterprises of the Mainland and Hong Kong in expanding into international markets. We look forward to the WSD continuing its proactive efforts in taking forward the water-related directions set out in Hong Kong's Five-Year Plan and in developing Hong Kong into an international hub for high-quality development of the country's water sector."
Mr Leung added that the ACWS will continue to provide professional advice to the Government on matters relating to water supplies and promote the continuous enhancement of Hong Kong's water supply services. The ACWS will fully support and align with Hong Kong's Five-Year Plan, actively contributing to the future development of both the nation and Hong Kong.
FEHD releases first batch of gravidtrap indexes for Aedes albopictus in October
The Food and Environmental Hygiene Department (FEHD) today (October 9) released the first batch of gravidtrap indexes and density indexes for Aedes albopictus in October, covering 17 survey areas, as follows:
| District | Survey Area | October 2026 |
| First Phase Gravidtrap Index | First Phase Density Index |
| Central and Western | Central and Admiralty | 0.0% | N/A |
| Kennedy Town and Shek Tong Tsui | 5.6% | 1.0 |
| Eastern | Chai Wan | 1.6% | 1.0 |
| North Point and Quarry Bay | 3.3% | 1.0 |
| Shau Kei Wan and Sai Wan Ho | 7.1% | 1.0 |
| Southern | Deep Water Bay and Repulse Bay | 1.7% | 1.0 |
| Wan Chai | Tin Hau and Causeway Bay | 2.0% | 1.0 |
| Wan Chai | 0.0% | N/A |
| Kwun Tong | Lam Tin and Sau Mau Ping | 9.4% | 1.2 |
| Yau Tong and Cha Kwo Ling | 3.4% | 1.0 |
| Wong Tai Sin | Diamond Hill and Tsz Wan Shan | 1.7% | 1.0 |
| Wong Tai Sin East | 2.1% | 1.0 |
| North | Fanling North | 2.3% | 1.0 |
| Fanling South | 4.7% | 1.0 |
| Sha Tin | Sha Tin East | 8.2% | 1.0 |
| Tsuen Wan | Sheung Kwai Chung | 1.9% | 1.0 |
| Tuen Mun | Tuen Mun South | 5.5% | 1.0 |
The FEHD continues to carry out a series of mosquito prevention and elimination measures, including:
- interdepartmental collaboration: convening special meetings of the interdepartmental task forces on anti-mosquito work to co-ordinate relevant departments and stakeholders (such as construction site contractors, schools and property management companies) in strengthening mosquito control work at venues;
- precise risk assessments: carrying out intensive and targeted mosquito control work at locations with more serious mosquito infestations, including stepping up inspections, eliminating mosquito breeding and potential breeding grounds, applying larvicides, conducting fogging operations to eradicate adult mosquitoes, and placing mosquito trapping devices at appropriate locations;
- promotion and education: organising exhibitions with relevant departments and stakeholders, and distributing leaflets and posters to enhance public awareness of mosquito control and prevention; and
- rapid alert mechanism: notifying residential estates that have subscribed to the gravidtrap Rapid Alert System, and advising property management companies and residents to stay vigilant and work together in taking mosquito prevention and elimination measures.
Public participation is crucial to the effective control of mosquito problems. The FEHD appeals to members of the public to continue to work together in strengthening personal mosquito control measures, including:
- tidying up their premises and checking for any accumulation of water inside the premises;
- removing all unnecessary water collections and eliminating the sources;
- checking household items (those placed in outdoor and open areas in particular), such as refuse containers, vases, air conditioner drip trays, and laundry racks to prevent stagnant water;
- changing water in flower vases and scrubbing their inner surfaces thoroughly, and removing water in saucers under potted plants at least once a week;
- properly covering all containers that hold water to prevent mosquitoes from accessing the water;
- properly disposing of articles that can contain water, such as disposable meal boxes and empty cans; and
- scrubbing drains and surface sewers with alkaline detergent at least once a week to remove any mosquito eggs.
Starting in August 2025, following the completion of the surveillance of individual survey areas, and once the latest gravidtrap index and the density index are available, the FEHD has been disseminating relevant information through press releases, its website and social media. It aims to allow members of the public to quickly grasp the mosquito infestation situation and strengthen mosquito control efforts, thereby reducing the risk of chikungunya fever (CF) transmission.
Following recommendations from the World Health Organization and taking into account the local situation in Hong Kong, the FEHD sets up gravidtraps in districts where mosquito-borne diseases have been recorded in the past, as well as in densely populated places such as housing estates, hospitals and schools to monitor the breeding and distribution of Aedes albopictus mosquitoes, which can transmit CF and dengue fever. At present, the FEHD has set up gravidtraps in 62 survey areas of the community, with a surveillance period of two weeks. During the surveillance period, the FEHD will collect the gravidtraps once a week. After the first week of surveillance, the FEHD will immediately examine the glue boards inside the retrieved gravidtraps for the presence of adult Aedine mosquitoes to compile the Gravidtrap Index (First Phase) and Density Index (First Phase). At the end of the second week of surveillance, the FEHD will instantly check the glue boards for the presence of adult Aedine mosquitoes. Data from the two weeks of surveillance will be combined to obtain the Area Gravidtrap Index and the Area Density Index. The Gravidtrap and Density indexes for Aedes albopictus in different survey areas, as well as information on mosquito prevention and control measures, are available on the department's webpage (www.fehd.gov.hk/english/pestcontrol/dengue_fever/Dengue_Fever_Gravidtrap_Index_Update.html#).
