Lesson 1: Household measures (fixtures, leaks)

Household water use can be significantly reduced by adopting efficient fixtures such as low-flow taps and dual-flush toilets.
Simple leak detection and repair can prevent the loss of up to 30 liters/day per household, which is a common issue in Libyan urban areas .
Public awareness campaigns in Tripoli and Jefara have shown that education about water-efficient behaviors (e.g., turning off taps when brushing teeth) can cut per capita use.

Resources

Greywater (wastewater from sinks, showers, and laundry) represents up to 50–70% of domestic water outflow.
In Libya, greywater reuse is especially relevant where treated wastewater infrastructure is lacking.
Safe reuse for garden irrigation or cleaning purposes reduces pressure on freshwater demand, provided simple filtration and storage practices are applied .

Schools and mosques are key sites for water saving: campaigns have successfully promoted water-efficient ablution facilities, cutting consumption in religious settings.
In agriculture, introducing drip irrigation in Jefara farms reduced water use by 30–40% compared to traditional flood irrigation .
Community water audits help identify points of loss in local networks, mobilizing collective action for leak repairs and infrastructure upgrades.

Long-term conservation depends on changing social norms.
Behavior change campaigns in Libya emphasize religious and cultural values, linking conservation to stewardship and responsibility.
Methods: WhatsApp groups, posters in community centers, and mosque announcements proved effective in raising awareness.
Youth engagement has shown particular success in spreading conservation messages within families and schools .
