What Domestic Wastewater Limits Apply Under PERMENLHK 68/2016?
1.0 Introduction
1.1 Regulatory Context
Peraturan Menteri Lingkungan Hidup dan Kehutanan Nomor P.68/Menlhk/Setjen/Kum.1/8/2016 tentang Baku Mutu Air Limbah Domestik establishes the regulatory framework for domestic wastewater quality standards in Indonesia. Issued by the Ministry of Environment and Forestry in 2016, this regulation implements Article 20 paragraph (2) point b of Law No. 32/2009 on Environmental Protection and Management.
The regulation addresses a critical environmental challenge: domestic wastewater from households and businesses has significant pollution potential and requires treatment before discharge into environmental media. By establishing clear quality standards and compliance mechanisms, PERMENLHK P.68/2016 creates a comprehensive framework for managing domestic wastewater pollution across Indonesia.
1.2 Scope and Applicability
This regulation applies to:
- Residential apartment buildings and multi-family housing
- Hotels, lodging facilities, and dormitories
- Healthcare facilities (hospitals, clinics, laboratories)
- Educational institutions (schools, universities, training centers)
- Office buildings and commercial complexes
- Markets and shopping centers
- Restaurants and food service establishments
- Recreation facilities and entertainment venues

Understanding these requirements is essential for facility operators, environmental managers, government regulators, and investors in Indonesia's urban infrastructure and commercial real estate sectors.
2.0 Wastewater Quality Standards
2.1 Core Parameters and Limits
PERMENLHK P.68/2016 establishes eight critical parameters for domestic wastewater quality, with maximum allowable levels at discharge points:
pH Level: Range 6-9 (neutral to slightly alkaline)
Biochemical Oxygen Demand (BOD): Maximum 30 mg/L - measures organic matter decomposition load
Chemical Oxygen Demand (COD): Maximum 100 mg/L - measures total organic pollutants
Total Suspended Solids (TSS): Maximum 30 mg/L - particulate matter concentration
Oil and Grease: Maximum 5 mg/L - hydrophobic substances
Ammonia: Maximum 10 mg/L - nitrogen compound affecting aquatic ecosystems
Total Coliform: Maximum 3,000 counts/100mL - bacterial contamination indicator
Discharge Volume: Maximum 100 liters/person/day - water consumption benchmark
2.2 Treatment Requirement
Article 2 paragraph (1) mandates that all domestic wastewater must be treated before discharge. This applies to all entities listed in paragraph (3), regardless of facility size or operational scale. The treatment obligation exists whether facilities operate individual treatment plants or connect to centralized wastewater treatment systems.
2.3 Stricter Regional Standards
Article 2 paragraph (2) permits provincial governments to establish more stringent wastewater quality standards based on scientific studies of environmental carrying capacity and available treatment technologies. When provincial standards are stricter than national standards, the provincial standards apply within that jurisdiction.
This provision recognizes regional variations in water body sensitivity, population density, and environmental conditions, allowing local adaptation while maintaining minimum national baseline protection.
3.0 Institutional Framework
3.1 Regulatory Authority Structure
Ministry of Environment and Forestry (KLHK): Establishes national standards, provides technical guidance, and coordinates national-level oversight
Provincial Governments: May establish stricter regional standards, oversee implementation within provincial boundaries, and coordinate between districts
District/Municipal Governments: Issue wastewater discharge permits, conduct inspections, enforce compliance, and impose administrative sanctions
Environmental Management Units: Provide technical assessment, laboratory analysis, and monitoring support to regulatory authorities
3.2 Facility Operator Responsibilities
Entities generating domestic wastewater must:
- Install and operate wastewater treatment systems meeting established quality standards
- Conduct self-monitoring of effluent quality at prescribed frequencies
- Maintain treatment equipment in proper operating condition
- Employ certified operators for treatment plant management
- Submit periodic monitoring reports to environmental authorities
- Respond to deficiency notices and implement corrective actions
3.3 Permit and Authorization Requirements
Article 3 requires that wastewater quality standards be incorporated into environmental licenses (Izin Lingkungan) for facilities subject to Environmental Impact Assessment (AMDAL) or Environmental Management/Monitoring Plans (UKL-UPL).
For facilities exempt from AMDAL/UKL-UPL requirements, wastewater standards are incorporated into Environmental Management Commitment Statements (SPPL), ensuring all domestic wastewater generators operate under enforceable environmental obligations.

5.0 Implementation and Compliance Pathways
5.1 New Facility Compliance
Entities planning new facilities must:
Phase 1: Planning (Design Stage)
- Incorporate wastewater treatment system into facility design
- Size treatment capacity based on projected occupancy/usage
- Select treatment technology meeting effluent standards
- Include monitoring infrastructure (sampling points, flow meters)
Phase 2: Authorization (Pre-Operation)
- Obtain environmental permit (AMDAL/UKL-UPL/SPPL)
- Submit wastewater treatment design to environmental authority
- Obtain construction permits per building regulations
- Secure certified operator commitments
Phase 3: Commissioning (Pre-Discharge)
- Complete treatment system construction per approved design
- Conduct performance testing demonstrating standard compliance
- Obtain operational approval from environmental authority
- Initiate self-monitoring program
Phase 4: Operation (Ongoing)
- Maintain continuous treatment system operation
- Conduct monthly self-monitoring of effluent quality
- Submit quarterly/annual reports to environmental authority
- Respond promptly to deficiency notices
5.2 Existing Facility Retrofit
Facilities operating before PERMENLHK P.68/2016 effective date (September 1, 2016) must:
Assessment: Evaluate current wastewater management against new standards, identifying gaps and non-compliances
Planning: Develop retrofit plan addressing deficiencies, including timeline and budget
Implementation: Install or upgrade treatment systems to achieve standard compliance within prescribed grace period
Verification: Demonstrate compliance through independent laboratory testing before resuming normal operations
Ongoing Compliance: Transition to standard monitoring and reporting requirements
5.3 Provincial Standard Adoption
Provincial governments wishing to establish stricter regional standards must:
- Conduct scientific study of local water body carrying capacity
- Assess available wastewater treatment technologies
- Consult affected stakeholders (businesses, communities, regulators)
- Develop evidence-based regional standard proposal
- Issue provincial regulation formally adopting stricter standards
- Provide implementation guidance and transition periods to affected facilities
6.0 Key Compliance Considerations
6.1 Multi-Parameter Compliance
All eight parameters must simultaneously meet prescribed limits. A facility exceeding limits on even one parameter is non-compliant, regardless of performance on other parameters. This requires holistic treatment system design addressing biological, chemical, and physical contaminants.
6.2 Continuous Obligation
Wastewater treatment is a continuous operational requirement, not a one-time installation. Facilities must maintain treatment systems in proper operating condition 24/7, preventing discharge of untreated or inadequately treated wastewater during equipment failures, maintenance, or operational upsets.
6.3 Self-Monitoring Integrity
Facilities bear primary responsibility for monitoring effluent quality and demonstrating compliance. Environmental authorities conduct oversight inspections and may require independent laboratory verification, but operators cannot defer to government monitoring to fulfill self-monitoring obligations.
6.4 Technology Neutrality
The regulation specifies performance standards (effluent quality limits) without mandating specific treatment technologies. Facilities may employ any treatment approach consistently achieving required effluent quality, allowing technological innovation and site-specific optimization.
6.5 Carrying Capacity Considerations
Article 2 paragraph (4) references environmental carrying capacity and pollution load allocation. In watersheds approaching or exceeding pollution carrying capacity, authorities may impose additional requirements beyond minimum national standards, including stricter limits, discharge volume caps, or seasonal restrictions.
7.0 Conclusion
PERMENLHK P.68/2016 establishes a comprehensive and technically specific framework for domestic wastewater management in Indonesia. The regulation's strength lies in its multi-parameter standards, clear compliance obligations, and flexible enforcement tools. By requiring treatment before discharge and establishing measurable quality limits, the regulation protects Indonesia's water resources from domestic wastewater pollution while providing regulated entities with clear compliance pathways.
Successful implementation requires coordination among environmental authorities, facility operators, certified laboratories, and treatment technology providers. Entities subject to this regulation should prioritize early compliance planning, invest in reliable treatment systems, and maintain rigorous self-monitoring programs to ensure ongoing regulatory adherence.
As Indonesia's urban population grows and commercial development expands, effective domestic wastewater management under PERMENLHK P.68/2016 becomes increasingly critical to protecting public health, preserving aquatic ecosystems, and maintaining water quality for downstream users.
