Water and waste in Bali: what villa buyers should ask in 2026

Bali's 2026 water pressure, Suwung landfill changes, mandatory waste sorting and plastic rules, and what to ask about a villa's water and wastewater.

In 2026, water and rubbish stopped being background issues in southern Bali. Organic waste has been barred from the island’s largest landfill since April, every household has been required to sort its waste since July, and a long dry season put pressure on supply in parts of Badung. If you are buying a villa, these changes make a few practical questions more important than the view.

Water: supply under pressure in the south

Southern Bali draws its water from rivers, regional supply schemes and groundwater. All three are under strain.

  • Denpasar. In July 2026, the city water utility (PDAM Denpasar) said it produced about 1,400 litres per second from surface water, 18 deep wells and two regional schemes, while real demand at peak hour was about 1,550 litres per second. Both regional schemes were delivering well below their agreed volumes. The utility prepared tanker trucks for higher areas and said it was adding infiltration wells to help rain soak back into the ground.
  • South Badung. In September 2026, Badung officials met over a longer-than-usual dry season. Reported problems included falling flow at the Estuary Dam, tanker water costing residents in Ungasan up to IDR 60,000 per cubic metre, and saltwater intrusion from groundwater overuse reaching parts of Kuta. The Badung water utility said it plans seawater desalination for coastal areas such as Canggu and Kuta.
  • Groundwater status. In January 2025, the Deputy Minister of Energy and Mineral Resources said the ministry’s mapping placed Denpasar and Tabanan in the “critical” groundwater category.

The groundwater rule most buyers have not heard of

Indonesia regulates how much groundwater a household can draw without approval. Under Minister of Energy and Mineral Resources Decree No. 291.K/GL.01/MEM.G/2023, households using more than 100 cubic metres of groundwater a month need a groundwater-use approval. When it was announced in November 2023, the ministry said most households use only 20 to 30 cubic metres a month.

A villa with a pool, a garden and a full house of guests can use far more than an average household, and a villa run as a rental business may fall under different permit rules. The safe approach is simple: if a villa uses a well, ask whether a permit or approval is needed and whether it is in place, and have your notary or lawyer check the answer.

Waste: the Suwung landfill, sorting and plastics

Three changes matter for anyone living in or owning a villa in Denpasar or Badung.

  • Organic waste is no longer accepted at Suwung. Since 1 April 2026, the Suwung regional landfill, which serves Denpasar and Badung, has accepted only inorganic and residual waste. In March, Governor Wayan Koster said the site would close completely on 1 August 2026. In June, Environment Minister Jumhur Hidayat said the plan is to end open dumping rather than close landfills, with Suwung taking only sorted residual waste. Reports since then have differed, so check the current position with your banjar or waste collector. A waste-to-energy plant designed to process at least 1,200 tonnes a day is planned on six hectares in South Denpasar, with an 18-month build.
  • Sorting at source is now mandatory. From 1 July 2026, Bali became a national pilot for compulsory household waste sorting, covering homes, markets, hotels and offices. The Ministry of Environment reported that the ban on organic waste at landfill had already cut waste volume by up to 60 per cent in Denpasar and Badung.
  • Plastic rules are tighter for businesses. Governor’s Circular No. 9 of 2025 (Bali Clean from Waste Movement) requires hotels, restaurants and other businesses to sort waste, treat organic waste on site or through a local waste facility, and stop providing single-use plastics such as bags, straws and styrofoam, with a deadline of 1 January 2026. It also bans the production and distribution of single-use plastic drinking water bottles under one litre in Bali. Sanctions include review or revocation of business permits.

What to ask about any villa’s water and waste

Question Why it matters
Where does the water come from: PDAM mains, a well, or both? One source alone leaves you exposed in a dry season or an outage.
How much storage is there, shared and per villa? Storage covers the hours or days when supply drops.
Is the water filtered, and is there a recent lab test? Groundwater near the coast can carry salt or bacteria.
If there is a well, is a groundwater approval needed and in place? See the 2023 ministry rule above.
How is wastewater treated, and where does treated water go? A sealed bio septic system is very different from an old open soakaway.
Can the septic tank be reached for emptying? Desludging trucks need access without breaking floors.
Where does rainwater go? Infiltration wells return rain to the ground and reduce flooding.
Who sorts and collects rubbish, and is there space for it? Sorting is now compulsory, and organic waste needs a plan.

How we approached water and waste at Valora Sanur

Valora Sanur draws from two sources, a deep well and the PDAM mains, into a shared 20 m³ raw-water tank. From there, water is pumped to each villa’s own 2,850-litre roof tank and passes through a water filter in every villa. Wastewater goes to a bio septic system. Each villa has two infiltration wells, so rainwater returns to the ground on site, and rain chains guide roof water down visibly and quietly during heavy storms. If you would like to see how this is planned, visit the gallery in Sanur, open daily from 10 AM to 5 PM, or contact the team at atrea.id.
