Bali villa wells: household use and commercial permits

A working tap does not prove that a villa may lawfully use its well. The file must identify who draws the water, which well supplies it, what the water is used for, how much is taken and what monitoring exists.

Energy and Mineral Resources Minister Regulation 4/2026 separates groundwater used for business from specified non-business uses. Tourism, housing and other commercial operators apply for a business groundwater permit, called Izin Pengusahaan Air Tanah, through Indonesia's Online Single Submission licensing system (OSS). Certain non-business users instead apply for a groundwater-use approval called Persetujuan Penggunaan Air Tanah. The under-100 m³/month exception in this regulation concerns basic daily needs per household or group; it should not be used to label water consumed by a commercial villa operation as automatically exempt.

The confusion comes from mixing the building with the use

A villa can look like a home and still be operated as tourist accommodation. The applicable permit follows the actual use and applicant, not the architectural appearance or the name on an electricity bill.

Permen ESDM 4/2026 expressly lists tourism, tourism areas and other services, as well as housing, offices and commercial areas, among the activities that require the business-groundwater permit. The regulation separately describes non-business approvals and limited situations in which a non-business approval is not required.

So the correct first question is:

Is water from this well used for a business, basic household needs, another non-business purpose, construction drainage, monitoring or aquifer recharge?

Do not start with the 100 m³ number. Start by classifying the use. For example, a bore well supplying guest rooms, a pool and villa staff remains connected to a commercial accommodation activity even if a meter shows less than 100 m³ in a month. That figure alone does not establish a household exemption.

What a buyer should identify before signing

For every bore or dug well, create a one-well record:

• map pin and decimal-degree coordinates;
• physical location, depth, construction drawing and visible condition;
• construction date and drilling contractor, if known;
• legal holder/operator and the entity that pays any groundwater tax or charge;
• actual purpose: household, guest accommodation, staff, pool, irrigation, construction/dewatering or mixed;
• abstraction estimate in m³/day and monthly meter history;
• existing permit/approval number, issuing authority, issue and expiry date;
• meter, recharge well and monitoring/reporting evidence;
• inspection, warning, fine or complaint history; and
• alternative supply and closure/remediation plan.

If the seller cannot locate the well or explain who holds the document, “water included” is not a due-diligence answer.

New application does not mean one universal form

For the non-business approval described in Permen ESDM 4/2026, the application data include identity, address, decimal-degree coordinates, intended use, planned abstraction in m³/day, an undertaking to build a recharge well where applicable, and a construction plan. The authority can limit the approved withdrawal volume according to the conservation zone and hydrogeological data.

For business abstraction, the application is through OSS, while the detailed requirements and obligations also depend on the risk-based licensing rules for the energy and mineral-resources sector. No single authority, document or processing time can therefore be promised for every site.

Existing unapproved wells require immediate classification

The regulation creates regularisation and administrative-fine mechanics for unapproved or expired groundwater use. Its Article 15 three-year filing period is stated for non-business Persetujuan Penggunaan Air Tanah; do not apply that period automatically to a commercial villa's Izin route. For a business well, confirm the applicable regularisation process, possible fine and deadlines with the competent authority and a groundwater specialist.

As of this article's review date, do not market Article 15 as an open amnesty. An old unapproved well should go directly to a specialist for status, fine, application, closure or replacement advice.

Approval is not the end of the file

For the non-business approval route, obligations in the regulation include following technical conditions, installing an outlet meter except for monitoring wells, building a recharge well, allowing inspections, reporting hazards, remediating environmental damage and paying applicable public charges. Approvals for uses other than basic daily needs are generally issued for no more than seven years; an expired approval not extended can trigger a duty to close the well within 30 calendar days.

Supervision can be periodic through technical reports or incidental through site inspection. Administrative sanctions can progress from written warnings to temporary suspension and revocation.

Read the exact obligations from the business permit and the applicable risk-based licensing rules. Do not copy a non-business checklist into a commercial operator's file without validation.

Five deal questions that prevent an expensive surprise

1. Which person or entity draws the water after the purchase?
2. Is the use business, non-business or mixed, and who confirmed that classification?
3. Does the document identify this exact well, its coordinates, its use and the approved withdrawal volume?
4. Are meter, recharge, reporting, tax and inspection records current?
5. What happens to operations if abstraction is reduced, suspended or the well must close?

The answer should feed the operating budget: connection or tanker alternatives, storage, filtration, testing, meter work, recharge, renewal, professional fees and downtime.

Questions owners ask

We use less than 100 m³ a month. Are we exempt? Not necessarily. The exception cited in Permen ESDM 4/2026 is framed for basic daily needs, not as a blanket exemption for a tourism business.

The landowner drilled the well years ago. Can the villa company use it? Do not assume so. Match the holder, actual operator, use, coordinate and transitional status.

We pay groundwater tax. Does that prove the well is licensed? A payment record is useful evidence, but it is not a substitute for the applicable permit or approval.

Can this note determine which authority issues the document? It can help classify the case and prepare the evidence file. The competent authority and current application process require site-specific confirmation by a specialist.
