Water management in construction project

The Company places importance on water management in construction project in every process in order to have the least impact. The policy has been established for construction contractors and juristic persons to organize wastewater treatment management system and control and inspect the quality before releasing as required by law. The operating principles are as follows:

1.Create drainage system and temporary treatment system in the project before releasing water into public water channels. Water used in the project must be passed through the project’s temporary treatment system, consisting of sedimentation pond, waste trap, water retention pond, temporary drainage channel, and dredging public pipes. An aerated wastewater treatment system has been used to help reduce dirtiness of wastewater in the form of Biochemical Oxygen Demand (BOD) by up to 80-95%. The aerator which, in addition to increasing oxygen in the water, also causes the mixing of the water in the pond. This causes the decomposition of organic matter thoroughly within the pond in order to treat water so as not to affect the water quality of water sources near the project and to have good treatment before releasing it outside as much as possible. Additionally, staff are assigned to regularly clean, excavate ditches, drains, pipes, pits, and the drainage system both inside and outside the project.

2.Establish hygienic sanitation system within the project by building bathrooms to be sufficient for the number of workers, separating men and women, along with creating wastewater treatment system, adding microorganisms to eliminate unwanted odors, providing grease trap, and cleaning the bathroom regularly for good hygiene.

3.Check water quality within the project before releasing it into public pipes. Arrange for water quality inspection every month. The wastewater released from the construction project must have water quality measured, such as the acidity – alkalinity (pH), the number of suspended solids (SS), total dissolved solids (TDS), etc. From the water quality inspection, it was found that every project meets the standards of the Ministry of Nature and Environment before being released into public water sources.

4.Campaign to use water economically within the project. In construction projects, there is a campaign for everyone to use water economically to create awareness in using resources with value.

5.Reuse water in the reservoir All of the Company’s construction projects incorporate a process for reusing treated wastewater within the project site. Wastewater that has been properly treated is reused for various purposes such as watering plants, cleaning public roads, washing vehicle tires before exiting the site, and spraying water to suppress dust within the construction area. This approach enhances water use efficiency and reduces the discharge of wastewater into public drainage systems.

Sediments collected in the wastewater holding ponds are repurposed for land leveling and site preparation within the project area. Furthermore, the Company has initiated the measurement and monitoring of reused water volume in a pilot project, namely Origin Play Sri Udom Station, where treated water from holding ponds is reused effectively within the project. Based on monitoring results, the project achieved a water use reduction of approximately 120–160 units per month, representing around 10% of the project’s total water consumption.

In 2024, the Company set a target for at least 70% of construction projects to adopt water management practices that reuse no less than 10% of treated wastewater during the construction phase. For completed residential developments, the Company aims to implement treated water reuse systems, with a goal of establishing such practices in at least two pilot projects within the year.

These green spaces are capable of absorbing approximately 10,095 kilograms of CO₂ equivalent per year. The green space area in these projects represents 39.44% of the total area, in compliance with the Environmental Impact Assessment (EIA) requirements.

However, this figure is slightly below the company’s target by 0.56%, primarily due to the nature of the projects completed this year, most of which were smaller-scale developments with limited space. As a result, it was not possible to allocate as much green space as originally planned.

Despite the limited space, The Company has prioritized selecting tree species with effective carbon dioxide absorption capabilities, such as the Rain Tree, as well as plants that contribute to ecological balance and aesthetics. This approach aims to create a pleasant environment and enhance the quality of life for residents, bringing them closer to nature.

For 2025, The Company remains committed to prioritizing green spaces in every new project it develops. The goal is for new developments to have a green space ratio of no less than 40%, reflecting its dedication to sustainable and environmentally friendly real estate development.

Environmental Conservation and Management in Construction Activities

The Company has implemented operations in accordance with the guidelines set by the Ministry of Natural Resources and Environment. The Company maintains a policy to hire architectural, landscape architectural, structural engineering, and MEP (mechanical, electrical, and plumbing) consultants who are knowledgeable and competent in designing projects that meet the environmental standards set by the Office of Natural Resources and Environmental Policy and Planning (ONEP) under the Environmental Impact Assessment (EIA) framework. The policies, measures, and plans are divided into two key areas:

1. Project Safety (SAFETY PLAN)

The Company recognizes the importance of safety at every stage of project development. Therefore, a safety-focused plan is established from the site preparation stage, through construction, and post-construction. These safety measures are detailed in the EIA report and included in contracts with all contractors. They cover:

Construction areas, adjacent areas, and protection for workers (e.g., safety equipment and protective gear)
Safety protocols for authorized visitors entering the site
Emergency response and accident prevention plans, which are mandatory for every project to ensure preparedness of all involved parties

2. Environmental Management

To minimize environmental impact both within the project site and surrounding areas, the Company enforces various environmental protection measures, such as:

Water management
Dust control
Tree conservation and integration into project design

For sites with large existing trees, the Company incorporates those trees into the project layout. Certified arborists are engaged to inspect and provide guidance on tree trimming and maintenance, instead of cutting them down. The findings are discussed during weekly site meetings to define control measures, preventive actions, and corrective steps—following, or even exceeding, EIA standards for environmental care.

Environmental Complaints Related to Business Operations

The Company operates with a strong sense of responsibility toward the community and society. It places importance on minimizing environmental impacts and avoiding activities that may negatively affect the quality of life of surrounding communities. To facilitate transparency and responsiveness, the Company has established communication channels and designated departments to handle social and environmental complaints. These channels are intended to make it as convenient as possible for affected individuals to file a complaint.

A dedicated unit is responsible for investigating and addressing all complaints, as well as communicating the resolution back to the complainant or related parties through the designated complaint channels.
