Marina Barrage Field: A Comprehensive Guide to its Functions and Benefits

Marina Barrage Field, a world-renowned reservoir in Singapore, is a remarkable feat of engineering that has transformed the city-state's water landscape. This comprehensive guide delves into the multifaceted functions, benefits, and significance of the Marina Barrage Field, providing valuable insights into its role in Singapore's sustainable development.

What is Marina Barrage Field?

The Marina Barrage is a dam constructed across the mouth of the Singapore River, forming a freshwater reservoir in Marina Bay. Completed in 2008, the barrage is part of Singapore's ambitious water management strategy known as the Four National Taps.

Key Functions of Marina Barrage Field

Marina Barrage Field serves a multitude of essential functions, including:

Damming and Reservoir Creation

• Prevents seawater from flowing into the Singapore River, creating a freshwater reservoir.
• Stores up to 15 million cubic meters of water, equivalent to 10 Singapore Sports Hubs.
• Supplies up to 10% of Singapore's daily water needs during the dry season.

Flood Control

• Prevents upstream flooding by regulating water discharge from the Singapore River.
• Mitigates downstream tidal surges by controlling the outflows from the reservoir.

Water Supply Diversification

• Contributes to Singapore's Four National Taps, providing a reliable alternative water source.
• Reduces the city's dependency on imported water and desalination.

Hydropower Generation

• Houses six hydroelectric turbines with a combined capacity of 2.4 megawatts.
• Provides clean and renewable energy, contributing to Singapore's sustainability goals.

Recreation and Tourism

• Offers a scenic boardwalk and viewing platform for relaxation and sightseeing.
• Hosts water sports such as kayaking, sailing, and fishing.

Benefits of Marina Barrage Field

The construction of Marina Barrage Field has brought numerous benefits to Singapore and its residents:

Fresh Water Supply

• Ensures a stable and reliable supply of freshwater, reducing reliance on imported and desalinated water.
• Protects Singapore's water resources from seawater intrusion and contamination.

Improved Flood Resilience

• Reduces the risk of flooding in low-lying areas along the Singapore River.
• Protects critical infrastructure and communities from water damage.

Enhanced Biodiversity

• Creates a freshwater habitat for aquatic life, supporting a diverse range of flora and fauna.
• Enhances the ecological balance of Marina Bay and its surrounding areas.

Sustainable Water Management

• Contributes to Singapore's water sustainability goals by providing a diversified and reliable water source.
• Reduces greenhouse gas emissions associated with water desalination.

Economic Development

• Supports water-related industries and businesses, creating job opportunities.
• Attracts tourists and visitors, boosting the local economy.

How does Marina Barrage Field Work?

The Marina Barrage Field operates on a simple but effective principle:

• Low Tide: Gates at the barrage are closed, preventing seawater from entering the reservoir.
• High Tide: Gates are opened to release excess water from the reservoir, preventing flooding upstream.
• Heavy Rain: Gates are adjusted to regulate water flow and minimize flooding downstream.

Construction and Design

The construction of Marina Barrage Field was a complex and challenging undertaking:

• Length: 350 meters (1,150 feet)
• Height: 6.1 meters (20 feet)
• Materials: Concrete, steel, and rubber
• Gates: 10 radial gates, each weighing 500 tons

Recognition and Awards

Marina Barrage Field has received numerous accolades for its innovative design and environmental benefits:

• 2008: Singapore Green Building Award - Green Mark Platinum Award
• 2010: World Water Council - Green Drop Certification
• 2011: Singapore Institute of Architects - President's Design Award

Future Plans and Sustainability Initiatives

Singapore's water management strategy is constantly evolving, with plans in place to enhance the role of Marina Barrage Field in the years to come:

• Expansion: Exploring the possibility of increasing the reservoir's storage capacity.
• Energy Efficiency: Improving the efficiency of the hydroelectric turbines to generate more renewable energy.
• Biodiversity Conservation: Implementing measures to protect and enhance the aquatic ecosystem within the reservoir.

Statistics and Facts

• Annual Water Savings: Equivalent to 50,000 Olympic-sized swimming pools.
• Flood Protection Area: Covers over 10,000 hectares (25,000 acres) along the Singapore River.
• Construction Cost: S$265 million (US$198 million)
• Water Quality: Meets the United States Environmental Protection Agency (EPA) standards for recreational water use.
