Water Management

SCG established Water Management Committee in 2014 to collaborate in defining a clear direction and strategy for integrated water resources management. This includes management of water balance and improvement of manufacturing processes, developing products that consume less water and increasing cycle of water usage and participated in water resources management with public and industry sectors.

Target

Within 2020, reduce the water withdrawal per production unit by 20% compared with 2014.

Strategy

 1. Reduce water-related risks

Manage water-related risks that may lead to production interruption and conflict with the community.

 2. Reduce water usage by increasing the efficiency of production processes and products

Continuously improve the production process to reduce water withdrawal from natural sources with expansion throughout the entire supply chain.

 3. Reuse treated water

Install a high-efficient water treatment system and advance water treatment process to reuse treated water instead of discharge.

 4. Capability building of water management personnel

Raise awareness and understanding of the importance of water sources, the social and environmental impact, through training and actual practices. To cultivate business development skill.

Actions in 2017

Preparedness of the eastern economic zone

SCG Chemicals has factories and manufacturing units located in Rayong province in the eastern region of Thailand, where demands for water are mainly for residential sectors, agriculture, industry and ecosystem rehabilitation. The three main reservoirs in Rayong are Dokkrai, Nongplalai and Klongyai. The piping system of these three reservoirs is connected to the Prasae Reservoir. Moreover, there is a project to connect this series of the piping network with reservoirs in Kaeng Hangmaew District, Chantaburi province. Once completed, this network will regulate water for both drought and floods in the future.

SCG Chemicals drew up a water situation scenario to forecast the water volume in the three main reservoirs. The findings show that the water is sufficient for the needs of the entire province of Rayong in 2017-2018.  SCG Chemicals also assessed a worst-case  scenario where there is a water scarcity, insufficient for all stakeholders, and integrated with Business Continuity Management assessment (BCM), to come up with a Business Contingency Plan (BCP) as guidelines for crisis management, as well as a  provision of reserve water resources to mitigate impact and damage.

Water Institute of Sustainability

SCG participates in the integrated water resources management collaboration with the Federation of Thai Industries (FTI). In 2016, Mr. Somchai Wangwatanapanich, Senior Vice President, SCG Chemicals was elected as a vice president of FTI, with the task of managing the Industrial Environment Institute and Water Institute for Sustainability (WIS). WIS’s mandate is to promote, support and improve the industrial environmental management, efficient water resource management, and ECO industrial town development, under the public-private sector and stakeholders’ collaboration for sustainable development.

Reducing Water Withdrawal from External Source

SCG increased the efficiency of production process and reuse treated water which reduced water usage from external sources by 3.92 million cubic meters, or 3.2% compared with BAU of 2914. In addition, SCG recycled water of 7.52 million cubic meters which was 6% of SCG total water consumption, SCG water withdrawal intensity (Revenue from Sales) of 0.26 liter/baht

Water for Agriculture

Siam Kraft Industry Co., Ltd. and Thai Cane Paper Public Company Limited. implemented the distribution of treated wastewater to farmers for agricultural activities including growing rice, sugarcane, eucalyptus and other seasonal crops totaling about 4.6 million cubic meters.

Water-Efficient Flushing

One of the most household use of water is the sanitary ware and each one has a long lifespan. A development of efficient flushing system therefore plays a key role in optimizing water usage for household. Siam Sanitary Ware Industry Co., Ltd. the producer of COTTO sanitary ware conducted a research and development of a highly efficient flushing system to reduce water use since 1989. This innovation is able to reduce water use by 30%, from a normal toilet ware that requires 9 liters of water per flushing. Working on the R&D have been being continued and currently COTTO sanitary ware uses only 2.5/4 liters of water. COTTO sanitary ware received Australia’s certification of Water Mark and Water Efficiency Labeling and Standard (WELS) Scheme. The consumers of COTTO sanitary ware contributed to water savings of 60 million liters/year (calculated from the average water use per day according to LEED standard) compared with the average water use of sanitary wares, according to industry standard.

Water Footprint

SCG has applied Water Footprint assessment tools with various companies, and has been preparing personnel capability so that they can utilize these tools to benefit the business operation. In 2017, SCG sent its employees on a study visit to the Water Resource Agency (WRA) in Taiwan to study the application of Water Footprint assessment tools. WRA is the policy advocacy unit for the public water resources management, by supporting industrial factories to conduct water footprint assessment, and using the data to manage water usage within the factory. The goal is to reduce water loss in production processes, and for the public sector to obtain water usage data in the industrial sector to plan and formulate water resource management for the national water demand.
