Build – Operate – Tranfer

Shared investment resources – Optimized operations – Long-term value creation

Developing water and wastewater treatment facilities requires substantial capital investment, specialized technological expertise, and a comprehensive plan for managing the facility throughout its life cycle. For industrial parks, manufacturing plants, and infrastructure developments, selecting an appropriate investment model can directly influence capital efficiency, risk management, and long-term project sustainability.

Build–Operate–Transfer (BOT) is a cooperation model in which an investor or designated project entity arranges the construction and operation of a facility for an agreed period before transferring it to the receiving party under predetermined contractual conditions.

With specialized expertise in water treatment, wastewater treatment, and water reuse, Koastal Eco Group seeks to work with investors and partners to develop environmental infrastructure solutions aligned with actual demand, investment conditions, and long-term operational objectives.

BOT models for water and wastewater infrastructure

In the environmental sector, the BOT model may be considered for centralized wastewater treatment facilities in industrial parks, industrial water treatment systems, factory wastewater treatment plants, and other environmental infrastructure projects with stable, long-term operating requirements.

Depending on the project characteristics and cooperation structure, the parties will agree on the investment scope, construction responsibilities, operating arrangements, payment mechanisms, cooperation term, and transfer conditions.

Each project must be assessed in terms of technical feasibility, financial viability, legal requirements, and the facility’s long-term operating potential.
Areas of cooperation with Koastal Eco Group

1. Site assessment and feasibility evaluation

• Assess water or wastewater treatment demand, anticipated capacity, and influent characteristics.
• Evaluate site conditions, supporting infrastructure, and treated water quality requirements.
• Identify water demand, wastewater collection arrangements, and treatment requirements.
• Conduct preliminary assessments of alternative technologies, investment options, and operating models.
• Work with investors and relevant stakeholders to establish the technical basis for project development.

2. Technology and investment planning

Develop treatment solutions suited to project requirements and operating conditions.

• Propose system configurations, design capacities, and facility components.
• Evaluate initial capital expenditure, operating costs, and life-cycle maintenance requirements.
• Assess alternative arrangements for investment responsibilities, operational management, and risk allocation.
• Provide technical inputs to support project negotiations and the development of cooperation agreements.

3. Facility design and construction

Within the agreed contractual scope, Koastal Eco can participate in engineering design, equipment supply, civil construction, and the integration of process, electrical, instrumentation, and automation systems.

Project execution focuses on consistency between design and construction, practical operability, and compliance with the project’s quality and schedule requirements.

4. Facility operation and management

During the operating period, the parties establish clear responsibilities for plant operation, maintenance, treated water quality monitoring, equipment management, and other facility-related obligations.

Depending on the cooperation structure, operating activities may include:

• Day-to-day facility management and operation.
• Monitoring treatment performance and treated water quality.
• Equipment maintenance and management of operating materials.
• Control of electricity, chemical, and other operating costs.
• Operational reporting and recommendations for technical improvements.

Performance indicators, payment mechanisms, incident response responsibilities, and risk allocation should be clearly defined in the relevant contracts.

5. Facility transfer

Upon expiry of the cooperation term or fulfillment of the agreed transfer conditions, the facility is transferred to the receiving party in accordance with the contractual arrangements and applicable laws and regulations.

The transfer process may include facility condition assessments, as-built documentation, process and equipment manuals, operational records, and the necessary instructions to support the receiving party in taking over, managing, and operating the facility.

Benefits of the BOT model for investors

• Flexibility in resource mobilization: Provides a framework for the parties to consider investment and operating responsibilities suited to the project’s objectives.
• Integration of technology and operational requirements: Considering design, construction, and operation together helps reduce the risk of facilities being developed without sufficient consideration of long-term operational needs.
• Improved life-cycle management: Maintenance requirements, treatment performance, and operating costs can be addressed from the early stages of project development.
• Clear allocation of responsibilities: Cooperation arrangements and transfer conditions are established contractually, providing a basis for managing schedules, quality, and obligations throughout each project phase.
• Long-term environmental performance: Facilities are developed to meet applicable treatment requirements, use resources efficiently, and support sustainable operation.

A technological foundation for long-term cooperation

Koastal Eco Group focuses on three core areas of expertise: water treatment, wastewater treatment, and wastewater reuse and resource recovery. With nearly 200 professionals, more than 240 projects in Vietnam, over 500 projects internationally, and a combined wastewater treatment capacity exceeding 600,000 m³/day, based on company-provided figures, Koastal Eco has experience supporting environmental infrastructure projects of varying scales.

Each BOT opportunity requires an individual assessment based on actual demand, technological feasibility, financial arrangements, the applicable legal framework, and the allocation of responsibilities among the parties.

Koastal Eco Group – Partnering to develop sustainable water infrastructure

Koastal Eco seeks to establish long-term partnerships with investors, infrastructure developers, and organizations planning to develop and operate water and wastewater treatment facilities.

By combining technological capabilities with appropriate project delivery and operational strategies, the parties can explore cooperation models that improve investment efficiency, manage life-cycle risks, and respond to increasingly stringent environmental requirements.
