Urban Sludge And Septage Management In Asia Pacific

Introduction

As sanitation systems expand beyond sewered areas, urban sludge and septage management has become a priority for governments across Asia Pacific. Many small and mid-size cities still rely on on-site sanitation systems like septic tanks and pit latrines, requiring periodic desludging and safe treatment.

Countries like India, Bangladesh, Vietnam, Indonesia, and the Philippines are now funding Faecal Sludge Treatment Plants (FSTPs), co-treatment at STPs, and public-private models for desludging services. These efforts are part of broader goals under universal sanitation and water-safe cities.

FSTPs and Desludging Contracts Are Expanding in Mid-Sized Cities

The urban sludge and septage treatment market in Asia Pacific is expected to grow at a CAGR of 8.5% from 2026 to 2035. In India, AMRUT 2.0 was launched on 1 October 2021 to build water-secure, inclusive cities by providing 2.68 crore tap connections and 2.64 crore new sewer connections across 500 cities. The Mission focuses on universal coverage of sewerage and septage management. Similar efforts are underway in Indonesia’s Kalimantan and Sulawesi provinces and Vietnam’s Mekong delta towns.

Plants typically include screening, grit removal, anaerobic digestion, and dewatering units, with compost or energy recovery as output streams. Cities are exploring partnerships with private desludging operators under performance-based O&M contracts, service-level agreements, and even franchise models.

Support from ADB, Bill & Melinda Gates Foundation, JICA, and national sanitation agencies is enabling capacity-building, monitoring tools, and local government financing.

Emerging vendors include Eram Scientific, Tide Technocrats, Recykal, Blue Water India, and others offering modular mobile FSTPs, real-time service tracking, and end-to-end operator platforms.
