Practices
Structuring a PPP to solve water and sanitation challenges
Santa Marta, a tourist city of half a million people, struggled for years with drinking water shortages, flooding, and inadequate wastewater disposal. Delayed investments, climate impacts, and lack of stormwater systems left residents paying extra for water or recovering from damage. To address these issues, the National Planning Department selected Santa Marta as a pilot for a public-private partnership. CDM Smith, with Castalia and Durán & Osorio, structured a comprehensive plan to ensure reliable aqueduct and sewerage services for the next 30 years.
Improve distribution networks
Rehabilitation and expansion works aim to reduce technical losses by 10% and extend service coverage.
Develop stormwater collection
A complete storm sewer system will be built, alongside upgrades to pumping stations and collectors.
Upgrade wastewater disposal
Plans include screening lines and a new submarine outfall to strengthen treatment capacity.
The PPP scheme will deliver a dignified aqueduct and sewerage system, guaranteeing reliable service for residents and tourists. With an investment plan of 2.8 billion pesos over 30 years, the project allocates 40% to water supply, 30% to storm sewerage, and 25% to sanitary sewerage. Results will be measured against service continuity, reduced non-revenue water, expanded coverage, and improved drinking water quality. Supported by financial modeling and a risk matrix, the project ensures legal and commercial viability. Once implemented, Santa Marta will achieve modern water infrastructure standards, securing its growth and tourism-driven economy.
