Hong Kong – Adjustment of chemical usage at Stonecutters Island Sewage Treatment Works

Adjustment of chemical usage at Stonecutters Island Sewage Treatment Works


     ​The Drainage Services Department (DSD) announced today (March 27) that it will start tomorrow (March 28) to adjust the dosage of sodium hypochlorite solution (referred to as bleach), a chemical used to control bacterial levels in the disinfection system of the Stonecutters Island Sewage Treatment Works. Due to the impact of the COVID-19 epidemic on freight, the supply of chemicals to the Stonecutters Island Sewage Treatment Works has recently been unstable. Therefore, the DSD needs to adjust the amount of bleach used by the sewage treatment works in a timely manner so as to make more effective use of the existing stock to maintain the sewage treatment service. 


     As part of the epidemic control measures, the Leisure and Cultural Services Department has closed all the gazetted beaches under its management, including those in Tsuen Wan. Therefore, the above temporary operational arrangements will not pose additional health risks to the public. Nevertheless, the DSD, together with the Environmental Protection Department, will strengthen the monitoring of the water quality of nearby waters.

Advantage of Chemical Free Farming

Organic farming is recognized as a sustainable agriculture practice promoting  use of   organic/ bio inputs that  takes care of environment (including soil, biodiversity)  and  human wellbeing. Organic farming practices such as crop rotations, inter-cropping, cover crops, use of organic fertilizers and minimum tillage improves biodiversity, nutrient content and water retention capacity of the soil. Organic agriculture also contributes to mitigating the greenhouse effect and global warming through its ability to sequester carbon in the soil (FAO). 

Organic foods are safe and healthy and also boost immunity. With increased awareness on organic foods, people are inclining more towards organic products and it is fact that since the advent of COVID-19, the demand of organic product has increased in domestic market. The domestic market is growing @ 17% and the projected demand of organic food market is likely to cross Rs. 87.1 crore by 2021 from the Rs. 53.3 crore in 2016 (ASSOCHAM –EY). The export market size of organic products has increased by 42% during the current year (2021) compared to last year and the volume of organic products exported from April 2020 to February 2021 is 819250 MT with value of 948 million USD.

In view of increasing demand of organic food and realizing the advantage of chemical free farming for environment and human life, Government of India has been promoting Organic farming in the country through dedicated schemes namely Paramparagat Krishi Vikas Yojana (PKVY) and Mission Organic Value Chain Development for North Eastern Region (MOVCDNER) since 2015-16. Both the schemes stress on end to end support to organic farmers i.e. from production to certification and marketing.
