Study Notes
Definition and Classification of Water Use
- Water is critical for modern civilization, with demands far exceeding historical usage.
- Cleanliness standards today require significantly more water than in the past.
- Growing populations necessitate increased agricultural land and improved storm drainage, water supply, and sewerage systems.
- Industrial growth leads to heightened water use in processes and electric power production.
Future of Water Resources Engineering
- Future engineers will engage with innovative technologies and concepts in water management.
- Key areas of focus will include wastewater reclamation, weather modification, and land management for enhanced water yield.
- Water-saving techniques and recreational water usage are also on the rise.
Environmental Considerations in Water Management
- Environmental flows (10% of available flow) are essential for maintaining aquatic habitats.
- Fish ladders support ecosystem sustainability by enabling fish passage.
Sources of Fresh Water
- Freshwater sources include groundwater, rivers, lakes, and reservoirs such as Laguna Lake and Angat Reservoir.
- Freshwater is a renewable resource, but supply is diminishing globally.
Water Demand and Supply Challenges
- Water demand often outstrips supply in many regions, exacerbated by rising populations.
- Critical resource under threat, requiring effective water management strategies.
Water Resource Usage
- Water resources are primarily for:
- Agricultural (70% of global water usage)
- Industrial (22% of global water usage)
- Residential (8% of global water usage)
- Recreational
- Environmental activities
Agricultural Water Use
- Essential for irrigation and aquaculture, impacting food security and farmer livelihoods.
- Example project: Balog-Balog Multi-Purpose Project with an irrigation capacity of 34,410 hectares, hydropower generation of 43.5 MW, and a dam storage capacity of 560 million cubic meters.
Industrial Water Use
- Key industrial applications include:
- Hydroelectric plants reliant on dam and river runoff for power generation.
- Thermo-electric power plants using water for cooling (e.g., coal, nuclear, geothermal).
- Chemical processes at ore and oil refineries.
- Water-intensive manufacturing plants utilizing solvents.
