Regulation Watch · Environmental Compliance · Indonesia. The regulation applies nationally to homes and buildings that generate domestic wastewater, including hotels and other accommodation, apartments, offices, healthcare facilities, schools, shops, markets, restaurants, recreation venues, industrial sites, ports, airports and transport terminals. It also governs central and local governments, wastewater system operators and licensed wastewater service businesses.
New Wastewater Rules Reach Hotels, Villas and Commercial Buildings
Permen PU 20/2026 requires homes and buildings that generate domestic wastewater to use a compliant wastewater system, connect to an available centralised network and keep wastewater separate from drainage.
- Published
- Established in Jakarta on 16 September 2026 and promulgated on 13 October 2026 in State Bulletin 2026 No. 687. The Ministry of Public Works published the official record through its JDIH.
- Effective
- 13 October 2026, the date of promulgation specified by Article 91.
- Added to Watch
- 15 October 2026
Who is affected
Property owners, developers, landlords, tenants and operators of hotels, villas, apartments, housing, offices, healthcare facilities, schools, shops, markets, restaurants, recreation venues, industrial sites and transport facilities; PT PMA and PT PMDN companies that own, lease, develop or operate those properties; directors and facility managers; wastewater system designers, contractors and operators; and provincial, regency and city governments.
Practical impact
Every home or building that generates domestic wastewater must provide a compliant SPALD. A property within the service area of an already constructed centralised system, or SPALD-T, must connect unless it cannot technically be served. Wastewater and stormwater drainage must be separate. Commercial and higher-risk sources, including healthcare, retail, markets, restaurants, industry, ports, airports, stations and terminals, must add pretreatment before wastewater enters the collection system. Plans still being prepared and construction not yet started must follow the new regulation, while SPALD construction already underway may finish under the revoked 2017 regulation. The new instrument replaces Permen PUPR 04/PRT/M/2017 and sets detailed planning, design, construction, operation, maintenance, monitoring and business-operator requirements.
The Ministry of Public Works established Permen PU 20/2026 on 16 September, promulgated it in State Bulletin 2026 No. 687 on 13 October and made it effective that day. The regulation replaces Permen PUPR 04/PRT/M/2017 with a comprehensive framework for planning, constructing, operating, maintaining, monitoring and supervising domestic wastewater systems.
Its building-level reach is broad. Domestic wastewater includes toilet and non-toilet wastewater from houses, apartments, hotels and other accommodation, healthcare facilities, schools, offices, places of worship, shops, markets, restaurants, meeting venues, recreation areas, industrial sites, ports, airports, railway stations, terminals and correctional facilities. Article 7 requires every home or building that generates this wastewater to operate a SPALD under the new regulation.
Article 14 adds a direct connection rule. A home or building within the service area of an already constructed centralised wastewater system must connect to that system unless it cannot technically be served. Where a centralised connection is not available, the property must still use an onsite or other compliant system. Factory-produced treatment units require product certification, and effluent from both onsite sludge treatment and centralised plants must meet the environmental quality standards in force.
The regulation also changes property design and operations. Wastewater systems and stormwater drainage must be separate. Commercial and higher-risk premises such as healthcare facilities, retail premises, markets, restaurants, industrial sites, ports, airports, stations and terminals must provide pretreatment before wastewater enters the collection network. Within a connected property, the user is responsible for operating and maintaining in-parcel pipes, grease traps and control chambers, while the SPALD-T operator maintains the inspection infrastructure allocated to it.
The transition provisions matter for active developments. Plans still being prepared and projects whose planning is finished but construction has not started must comply with Permen PU 20/2026. Only SPALD construction already underway when the regulation took effect may continue under the 2017 regulation until completion. Property teams should document which transition category applies rather than assuming that an earlier design date protects an unstarted project.
The rule gives cities time to complete the physical separation of wastewater and drainage systems, with a deadline of 13 October 2036 for metropolitan and large cities and 13 October 2046 for medium and small cities. These dates do not defer the immediate rules for new planning, unstarted construction, technically available centralised connections, pretreatment, certified equipment, effluent quality or operation and maintenance. Owners, developers and operators should now reconcile engineering drawings, local service coverage, environmental approvals, PBG and SLF records, operating contracts and maintenance evidence.
Required action
- Map every owned, leased, developed or operated property that generates domestic wastewater and identify its use, wastewater sources, current treatment system, discharge route and responsible operator.
- Ask the competent local authority or SPALD operator whether each property is inside the service area of a constructed SPALD-T. Arrange a connection where service is available, or retain a documented technical basis where the property cannot be served.
- Confirm that wastewater pipes and treatment systems are separate from stormwater drainage. Review site drawings, as-built records, PBG and SLF files, environmental approvals, technical approvals and operating procedures for consistency.
- For hotels, restaurants, shops, markets, healthcare facilities, industrial premises and transport facilities, verify the required pretreatment, including grease and oil control or other measures needed to make the wastewater compatible with the collection system.
- Apply Permen PU 20/2026 to SPALD plans still being prepared and to projects whose planning is complete but construction has not started. Record the transition basis for any construction already underway under Permen PUPR 04/PRT/M/2017.
- Verify that factory-produced onsite treatment units or centralised treatment plants hold the required product certification, that effluent meets the applicable environmental quality standards and that sludge is removed and treated through an authorised route.
- Assign and document operation and maintenance responsibilities within each property. Users are responsible for in-parcel pipes, grease traps and control chambers, while the SPALD-T operator maintains the inspection infrastructure identified by the regulation.
- A business that provides SPALD services should confirm its cooperation arrangement and licence from the competent central or local government before operating.
