Foundations Give Way, Two Homes on Klungkung Riverbank Collapse
Two homes on Jalan Srikandi V, Banjar Sangging, Kamasan village, Klungkung district, Klungkung, Bali, collapsed after the foundations on the riverbank gave way. Both houses were empty at the time.
“I don’t know exactly when it collapsed because I was at an event at the time,” one of the homeowners, Ni Kadek Astini, 58, told detikBali on Tuesday (20 October 2026).
Astini suspects her house collapsed at around noon on Monday (19 October). She said she was shocked to find it had fallen down.
“When I got home, it was already like this. The other house had been unoccupied for about a month,” she added.
A visit to the site showed that police lines had been put up around both properties. The buildings that fell into the river had not yet been removed.
Klungkung Police public relations chief I Dewa Nyoman Alit Purnawibawa said the homeowners reported the incident at about 9am on Tuesday. He said both houses stood on leased land.
“The two affected homeowners are Ni Wayan Muliani, 53, a secretary at Akah village administration, and Ni Kadek Astini, 58, a temporary employee who rents land belonging to Anak Agung Gede Rai Adnyana,” Alit said.
Damage to Muliani’s home included the collapse of a five-metre section of the southern retaining wall. The incident also caused the garage to collapse, cracks in the house walls and damage to the floor. Total losses are estimated at Rp75 million.
At Astini’s home, a section of the southern retaining wall and a seven-metre stretch of boundary wall gave way. A small shrine and a concrete chicken coop belonging to Astini also slid into the Tukad Subak Toye Hee river channel, with losses estimated at around Rp20 million.
“Material losses at the two homes total Rp95 million,” Alit said.
The two houses are in the Srinadi Klungkung Cooperative Housing complex, directly above the retaining wall along the Tukad Subak Toye Hee river channel.
Work is currently under way on a riverbank reinforcement project in the channel, led by the Bali-Penida River Basin Authority (BWS Bali-Penida). The homeowners have asked the housing developer and the authority to explain what happened and accept responsibility. However, according to initial coordination, the owners have not been able to produce building permits.
I Wayan Juliarta, the authority’s official in charge of irrigation and swamps, said BWS Bali-Penida was willing to help rebuild the riverbank retaining wall. This would be conditional on the homeowners complying with applicable rules, including keeping buildings at least one metre from the river channel.
The initial assessment is that the retaining wall’s failure may be connected to the buildings’ position above the river channel, the condition of the fill soil and the impact of the riverbank construction work. “However, the precise cause is still awaiting the results of a technical examination,” he added.
