Background
Wastewater and sewerage governance in Cambodia involves both public works administration and drinking water service systems, which creates a need for coordinated billing and service rules across ministries. Sewer service fees are a utility financing mechanism that can be linked to water consumption bills when the legal procedure is clearly defined. A formal inter-ministerial prakas is used in Cambodia to set administrative procedures when responsibilities are shared between ministries.
Urban wastewater management depends not only on physical drainage and sewer networks but also on workable revenue collection arrangements. Billing integration can reduce fragmentation between clean water service provision and sewer system cost recovery. The General Department responsible for wastewater systems under MPWT has a system-level role in developing the legal framework for sewer infrastructure administration.
On 22 April 2026, Secretary of State Ros Vanna of the Ministry of Public Works and Transport led a meeting at the ministry to review a draft inter-ministerial prakas on the formality and procedures for incorporating sewer system usage fees into clean water bills. Participants included Secretary of State Sim Sitha and technical officials from the Ministry of Industry, Science, Technology and Innovation, along with MPWT officials from the General Department of Wastewater Systems, legal departments, and the drafting team working within the legal framework for wastewater systems.
Scope of Application
The draft regulation concerns the procedures for arranging the inclusion of sewer system service fees in clean water invoices. Based on the ministry statement, the instrument is inter-ministerial, indicating shared administrative responsibility between MPWT and the Ministry of Industry, Science, Technology and Innovation.
The subject matter is procedural rather than a new physical infrastructure project. It relates to how sewer usage charges would be organized within existing utility billing processes for clean water customers, under a formal legal instrument.
Key Provisions or Decisions
The meeting was held to examine and discuss the contents of the draft inter-ministerial prakas. According to the official statement, representatives of the two ministries reached final agreement on the draft.
Following that agreement, the drafting team was instructed to prepare the finalized draft for submission to the leadership of both ministries for review and signature. The source does not provide the detailed text of the draft provisions, fee levels, implementation dates, or the categories of users affected.
Implications for Investors, Businesses, or Compliance
If signed, the inter-ministerial prakas would provide a formal administrative basis for integrating sewer service charges into clean water billing. That would be relevant for water utilities, urban service operators, property managers, industrial users, and other entities that monitor utility cost structures and billing compliance.
For businesses and investors, the main long-term significance is regulatory clarity in utility charging procedures rather than an immediate change described in the source. A defined billing procedure can support more predictable wastewater service administration, especially in areas where sewer and water services intersect operationally.
