Floodings and drought disasters continue unabated due to climate impact, notably El Nino in 2023 which affected communities, society and SCG’s production. SCG therefore implements disaster preparedness through monitoring and forecasting jointly in partnership with state agencies and other organization for water piping system and network to mitigate risk to industrial production. SCG actively disseminates technical knowledge and expertise as leader of water resource managment in the private sector.


  • Reduce water withdrawal 23% by 2025 compared to 2014 base year
  • Maintain all water quality discharges (BOD, COD, TSS) above and better than standards


  • 24.09% reduction of water withdrawal compared to 2014 base year
  • All water quality discharges (BOD, COD, TSS) are better than standards


1. Reduce water-related risk through integrated water management.
2. Reduce water withdrawal by increasing consumption efficiency in production processes and product.
3. Ensure compliance of waste water treatment, monitor closely both volume and quality; incident reporting, root cause analysis; and reduce wastewater discharge.
4. Reuse treated water.
5. Restore water-related ecosystems and support water supply for community and agriculture.
6. Build capability employees to ensure integrated water management and optimization.

Replenishing water back to Nature and Community

Wet Forest Project at Lampang Cement Plant
Cement-Building Materials Business rehabilitates and conserves ecosystem inside its Lampang cement plant by implementing the “wet forest system”according to the Royal Initiaitve since 2003. This system features a network of 7,000 check dams, forest fire break along  14,000 metres, solar-powered pumps to replenish water into the forest, the Stop Log in Huay Pu creek which boosts water reserve for the “wet forest system” in the amount of 12,000 cubmic metres per year, on top of a separate water reserve system for plant consumption.

Conserving Environments from the Mountain through the Sea

SCGP (Packaging Business)’s Wangsala complex and Ban Nonghin-Khaosoong Community in Kanchanaburi jointly implemented a check dam project to address drought.  The project has a network of 10,550 check dams to date, with 500 added in 2023. The plan is to have 14,050 check dams by 2050. 

Eastern Region Water Management

Intense weather event of El Nino 2023 heightened water shortage risk in Thailand’s eastern region. SCG Chemicals (SCGC) joined with key stakeholders in collective water management to ensure adequate supply for all.

Participated OrganizationRoles of SCGC (Chemicals Business)
Eastern Economic Corridor Water Management Subcomittee under the National Water Resource Committee (NWRC)Represents the industry in water risk management planning
Water Trends Monitoring and Analysis Subcommittee of 17 Irrigation Offices nationwide, and 16 public agencies.Joins weekly preparedness and response meeting of water impact on industry.
East Coast Basin Committee, Office of National Water ResourceChosen as industry representative in the Eastern Basin Committee to give inputs in management and prioritization of water supply, drought and flooding management in Rayong, Cholburi, Chantaburi and Trad.
Water and Environment Institute for Sustainability, Federation of Thai Industries (WEIS FTI)As Institute Chair and Lead of Water Working Group, with the goal of promoting efficient water management and fostering collaboration among water users and managers at basin and national levels.

COTTO water saving products

  • COTTO sanitaryware VIZIO won the Product Innovation Awards 2023, water conservation category with 6 liters per minute through ION Mist : Sterilized Water, an innovative cleaning system that works to reduce up to 99% of bacteria buildup.
  • Showerhead model CT6216 uses water at the rate of 6.4 liter per minute for the soft version, and 7.2 liter pre minute for the hard version, saving up to  20% water compared to the standard of 9 liter per minute.

Success Cases

  1. Water usage reduction of 90,000 cubic meters per year in SCGC (Chemicals Business) factories.

In 2023, efforts continued with key projects such as:

  • Map Ta Phut Olefins boosted efficiency of its Low Pressure Steam, reducing water use by 11,650 cubic meters per year.
  • Thai Polyethlene switched conditioning chemicals in its cooling tower, to save 8,000 cubic meters per year.
  • Thai Plastic and Chemicals (TPC) uses technology to monitor and check water data usage to boost efficiency, resulting in saving 15,000 cubic meters per year.

2. Water usage reduction of 2.2 million cubic meters per year in SCGP (Packaging Business) factories.\

In 2023, efforts continued with key projects such as:

  • Treated water is reused within the sealed systems inside equipment. It is installing more of these alongside filtering system for treated water for reuse in production processes

Activated sludge Effluent treatment system, SCGP (Packaging Business) that utilizes microorganisms to break down pollutants in wastewater and transform them into microbial cells. The microorganisms are then separated from the water, resulting in treated water that better than the government standards. This treated water can be reused within the factory or supplied to farmers in agricultural areas. Additionally, it can be discharged into the environment.
