6.4.2 Efficient Water Use in Landscape Maintenance

Responsible Landscape Water Management

Universiti Malaysia Perlis (UniMAP) practices responsible and efficient water management in maintaining its campus greenery.

To ensure the sustainability of the landscape ecosystem, UniMAP has appointed three contractors, each responsible for landscape maintenance in different zones across the campus.

Watering activities are conducted twice daily, focusing primarily on newly planted species to ensure healthy establishment and growth.

Use of Recycled Water from Retention Pond

In line with UniMAP’s sustainability efforts, water used for landscape maintenance is sourced from the campus retention pond, reducing reliance on treated potable water.

Each contractor uses approximately one medium water tank (2,500 litres) per watering session.

This approach demonstrates UniMAP’s commitment to recycling and reusing water for non-potable purposes.

Water Usage Calculation

The total estimated annual water usage for landscape watering is calculated as follows:

Water needed per contractor per day: 2,500 L    

Watering frequency: 2 times daily            

Working days per month: 26 days            

Months per year: 12 months      

Number of contractors: 3             

Formula:

2,500 L × 2 × 26 × 12 × 3 = 4,680,000 litres per year

Sustainable Impact

By utilizing non-potable water from the retention pond and maintaining controlled watering schedules, UniMAP effectively reduces demand for treated water while ensuring the vitality of campus greenery.

This initiative reflects UniMAP’s strategic alignment with SDG 6.4, which promotes increased water-use efficiency and sustainable management of freshwater resources.

Through efficient water planning, careful monitoring, and sustainable sourcing practices, UniMAP continues to demonstrate responsible stewardship of its water resources, ensuring a greener and more sustainable campus environment.
