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.
