Deficit analysis: service capacity assessment and planning in developing countries - case study in the Philippines

Area of Science:

• Environmental Engineering
• Public Health
• Urban Planning

Background:

• Existing demand analysis methods inadequately address chronic deficits in water supply, sanitation, and waste management.
• Municipal sanitation systems (MSS) often face challenges with service quantity and quality.
• A formal approach is needed to define and analyze these service deficits.

Purpose of the Study:

• To propose a formal analytical model for municipal sanitation systems (MSS) experiencing chronic deficits.
• To introduce definitions and notation for describing deficit states in sanitation services.
• To enable effective demand analysis for MSS with service quantity or quality issues.

Main Methods:

• Development of a novel analytical model for municipal sanitation systems (MSS).
• Introduction of specific definitions and notation for deficit states.
• Application of the model through a case study in Bacoor, Philippines.

Main Results:

• The proposed deficit analysis model provides a formal framework for understanding sanitation service shortfalls.
• The model allows for the evaluation of options to reduce identified deficits.
• The case study demonstrates the practical application of the deficit analysis model.

Conclusions:

• The deficit analysis model offers a structured approach to managing chronic service deficits in MSS.
• Formal analysis is crucial for improving the quantity and quality of drinking water supply (DWS), wastewater treatment (WST), and municipal solid waste (MSW) services.
• This framework supports evidence-based decision-making for enhancing urban sanitation infrastructure.
