Environmental Innovation

The Company recognizes the importance of environmental management and the potential impacts arising from its business activities. Based on the assessment of environmental issues throughout the supply chain, the Company has established measures to prevent pollution and address various environmental concerns in order to minimize impacts on the environment, while promoting environmental protection and restoration for sustainable development in accordance with the ISO 14001 Environmental Management System. The Company has been certified under the ISO 14001 Environmental Management System since 2007 (ISO 14001:2004) and continues to maintain certification under the current standard (ISO 14001:2015). The certified scope covers the Company’s water pumping stations and pipeline network control rooms, representing 31.00% of the Company’s total operational areas.

Since 2023, the Company has organized a special training program to develop engineers’ innovation capabilities under the Engineering Improvement Program (EIP). The program lasts for nine months and aims to encourage the Company’s engineers to demonstrate their potential and create innovative solutions by applying Agile and Design Thinking concepts. The program enhances employee capabilities while fostering professional ethics in engineering and business management perspectives through a combination of hands-on workshops and coaching. It also promotes the development of innovations that improve operational efficiency, reduce costs, and create added value for the business, as well as identifying high-potential personnel for future expert development. The Company also launched the Quick Win Improvement 2023 project to encourage employees to participate in the creation and development of innovations. The success of the project has been defined as one of the Corporate KPIs and Common KPIs under knowledge management, serving as an extension of the EIP training program that translates classroom knowledge into innovation concepts.

In 2024, the Company selected innovative projects from the Quick Win Improvement 2023 initiative that demonstrate benefits in terms of operational efficiency, investment value, and environmental friendliness, and further developed them in 2025, as follows:

IoT Datalogger (EW logger)

The Company faced challenges in installing control systems and monitoring systems along the raw water pipeline network, including systems for preventing corrosion of underground steel pipelines. These data are critical for analyzing water transmission efficiency, managing water resources, and planning long-term pipeline maintenance. To address these limitations, the Company developed the IoT Datalogger (EW Logger), which functions as a device for collecting and transmitting data through the IoT network. The innovation was designed and developed by the Company’s employees.

This innovation applies the operational principles of the SCADA system to replace conventional control and communication equipment that requires large installation space and high costs. As a result, the Company can effectively reduce communication equipment and construction costs.

Installation Areas and Implementation Plan :

Installation has been carried out for 11 pressure monitoring units and 6 CP monitoring units within the pipeline network in Rayong and Chonburi provinces.

Results :

  1. The IoT Datalogger (EW Logger) reduced procurement costs for datalogger equipment by 70% (approximately 595,000 Baht)
  2. Easy installation in limited spaces.
  3. Suitable for operation in real environmental conditions.
  4. Can be further developed based on the existing monitoring and SCADA systems.
  5. Reduced environmental impacts from construction activities and energy consumption.
