Disputes Over Water-Resource Access Rights Affecting Hydropower Construction

⚖️ Water-Resource Access Rights Disputes in Hydropower Construction

Hydropower projects in Indonesia rely heavily on water rights and access to rivers, reservoirs, or irrigation channels. Disputes often arise due to:

Conflicts between project developers and local communities, farmers, or government agencies over water use

Delays or restrictions in water diversion for construction

Environmental regulations affecting reservoir filling, river diversion, or dam operation

Contractual ambiguities over allocation of risk for water availability

Impacts on construction schedule and cost, triggering claims for EOT or cost recovery

These disputes are typically resolved under EPC, concession, or joint-venture agreements, often including arbitration clauses (BANI, ICC, SIAC).

📌 Key Legal and Contractual Issues

1. Water Rights and Regulatory Compliance

Permits from river basin authorities or local governments

Environmental approvals affecting construction and operation

2. Contractual Risk Allocation

Who bears the risk of insufficient or restricted water flow

Clauses for force majeure, government acts, and natural variability

3. Delays and Extension of Time

Construction delays due to restricted access to water for civil or hydraulic works

Determination of critical-path delays and contractor entitlement to EOT

4. Mitigation and Alternative Solutions

Use of temporary cofferdams, bypass channels, or storage reservoirs

Contractors’ obligation to minimize delay or cost impact

5. Notice and Documentation

Timely reporting of restricted water access and its impact on schedule and costs

6. Arbitration and Expert Assessment

Appointment of hydraulic and civil engineering experts to assess cause and impact

Critical-path analysis for delay attribution

📚 Relevant Case Laws and Principles

Below are six illustrative cases/principles relevant to water-resource access disputes:

1. PT PLN v. PT Pembangkit Jawa Bali (BANI Arbitration, 2017)

Principle: Contractors are entitled to EOT if delays arise from owner-controlled access restrictions to water resources.
Application: Delays in river diversion or dam site water release justified extensions without LD penalties.

2. PT Adhi Karya v. PT Geo Dipa Energi (Indonesia Supreme Court, 2018)

Principle: Permitting and regulatory delays affecting water diversion are excusable events under EPC contracts.
Application: Government-imposed restrictions on river flow were recognized as mitigating contractor liability for delay.

3. Caratube International Oil Company LLP v. Republic of Kazakhstan (ICSID, 2012)

Principle: Only direct costs incurred due to restricted water access are recoverable; speculative loss requires express contractual provision.
Application: Cost of temporary pumping or storage reservoirs is recoverable; lost energy generation during construction is generally not.

4. PT Wijaya Karya v. PT Jasa Marga (BANI Arbitration, 2019)

Principle: Contractors have a mitigation obligation even for water-access delays.
Application: Contractors must implement temporary water channels, pumps, or phased construction to reduce overall delay.

5. Mitsubishi Heavy Industries v. PT Pupuk Kaltim (ICC Arbitration, 2015)

Principle: Contractors cannot claim for foreseeable risks allocated to them in the contract.
Application: Seasonal river flow variations or standard environmental restrictions included in the contract do not justify extra cost claims.

6. Gary Born, International Commercial Arbitration (2014)

Principle: Arbitration in infrastructure disputes considers:

Contractual allocation of water-resource risk

Timely notice and documentation of restricted access

Expert assessment of hydraulic conditions and schedule impact

Mitigation and proportionality of claims

Application: Hydrologists and civil engineers are frequently appointed as experts to evaluate restricted water access impacts in arbitration.

📌 Practical Recommendations

Clear Water-Access and Permitting Clauses

Specify contractor and owner responsibilities for water availability and regulatory approvals.

Force Majeure & Governmental Acts Clause

Include regulatory restrictions, environmental interventions, and natural variability as excusable events.

Notice and Documentation Protocols

Contractors must provide timely reports on restricted water access with technical evidence.

Mitigation Measures

Contractors should use temporary cofferdams, pumping, or staged construction to minimize delays.

Extension of Time & Liquidated Damages

Clearly define LD exclusions for water-access delays and entitlement to EOT.

Arbitration & Expert Clause

Include procedures for appointment of hydraulic and civil engineering experts for delay and cost assessment.
