PJV Network- Before committing to monthly villa rent on Bali take a few focused checks on official flood data and past weather patterns. These sources give concrete evidence of risk and help you choose a property that will stay dry during heavy rains.
Where to access official flood and hazard maps
Request maps from the local district office and the provincial disaster management agency and consult national hydrology records kept by government services. Local banjar or village offices often have community level maps showing historical watercourses and known flood zones. Ask the host to provide any municipal documentation they have on the parcel.

Key weather records to review
Look at at least five years of monthly rainfall and recent extreme one day totals to understand frequency of intense events. Pay attention to the wet season months and any recorded river gauge spikes or storm surge incidents for coastal properties. Tide and river level history matters for beachfront and riverside villas.
How to turn maps and data into a practical decision
Compare the villa elevation to nearby water features and prefer properties on higher ground or with visible raised foundations. Ask the host for evidence of past flooding dates and photos and confirm whether the villa has functioning pumps and backup power. If the data shows occasional flooding choose a villa with clear evacuation access and staff familiar with local emergency routes.
Use these official sources and weather records to make a specific choice rather than a guess. A short verification now reduces the chance of disruption during your one month stay.
Evaluate on‑site drainage features gutters and grading
Inspecting drainage on the property gives a reliable sense of how the villa will cope with heavy tropical rain. Visible systems and simple measurements often reveal problems that photos alone will not show.
Plan a short walk around the grounds and note any low spots where water collects after a storm or heavy shower. If possible ask the host to show the property during or immediately after rain to see real performance.
Gutters and downspouts Check that gutters run the full length of rooflines and are free of rust and blockages. Downspouts should direct water away from the foundation and not simply dump at the base of retaining walls.
Downspout discharge points Verify where water is released and whether it flows into a defined drain or open ground. Ideally water is routed at least two meters away from living areas or toward a dedicated channel.
Site grading and slope Look for a consistent slope away from the villa on all sides to prevent water pooling against walls. A gentle fall of just a few degrees is often enough to move surface runoff safely downhill.
Surface channels and culverts Note any paved channels, stone drains or concrete culverts and test their capacity by observing water flow. Blocked or undersized channels are common causes of local flooding around structures.
Permeable landscaping and retention Check for gravel, porous paving and planted swales that absorb rain rather than shove it toward buildings. Retaining walls with adequate weep holes help prevent trapped water behind terraces.
Document any deficiencies with photos and clear notes to discuss with the host before booking. Small fixes such as extending a downspout or clearing a channel are often simple to arrange and greatly reduce disruption during a month long stay.
Key questions to ask hosts about past flooding and pumps
When enquiring about a villa for a month ask direct and specific questions about any prior flooding and the condition of pumps so you can make a clear decision before booking. Ask whether the property has ever flooded and for the exact dates and highest recorded water level in living areas and outside spaces. Request photos or dated messages showing the incidents and ask how long water typically remained before receding. Ask what the documented cause was such as river overflow blocked drains poor site grading or coastal surge. For pumps ask whether an automatic sump pump is installed its rated flow in litres per minute and the date of the last service. Request proof of recent maintenance such as service receipts and ask whether there is a tested backup power source and how long that backup will run during a power cut. Ask if there is a manual pump or portable pump and whether staff know where it is and how to operate it. Verify whether drainage channels and gutters are cleaned on a scheduled basis and when that was last done. Ask if the host has an emergency plan including contact numbers for local pump technicians and whether staff have an evacuation route to higher ground. Request clarification on any previous insurance claims related to flooding and whether the property has had mitigation upgrades such as raised thresholds flood vents or sealed electrical panels. Finally ask the host to perform a live pump test while you are on site or to provide a short video of the pump running and the location of discharge so you can confirm practical readiness before committing to a one month stay.
Onsite inspection checklist for water entry points and utilities
Begin with a walkaround that focuses on obvious entry points and evidence of past water intrusion. Check door and window thresholds for raised sills and continuous seals and look for water marks or mold on interior walls and skirting boards. Inspect external vents and laundry or bathroom exhausts to confirm they are elevated and have backflow protection. Examine the base of retaining walls terraces and garden beds for erosion or scoured channels that could divert runoff toward the building. Note any pooled water or soft ground near foundations and test gutters and downspouts visually to ensure they discharge well away from living areas. Take dated photos of every suspect area to support any follow up with the host.
Turn attention to utilities and mechanicals and confirm readiness for heavy rain events. Verify the electrical distribution board is mounted above expected flood level and that external sockets and switches are sealed or raised. Ask the host to show the main water shut off valve and the sewer or septic access lid and to confirm whether backflow preventers or float switches are installed on pumps. Request a demonstration of any sump pump and of backup power systems and note the rated capacity and last service date. If anything looks undersized or corroded request maintenance or a written plan for rapid response while you stay. Keep clear records of the inspection and require the host to acknowledge any promises in writing before you commit to a one month booking.
Mitigation steps insurance and emergency plans to request
Prior to booking a month at a villa ask for specific mitigation measures insurance proof and an emergency plan so you have clear expectations. These items reduce uncertainty and ensure both host and guest understand responsibilities during heavy rain or flooding events.
Essential mitigation measures to confirm
Request confirmation that the villa has raised thresholds sealed electrical panels and functioning gutters that discharge away from foundations. Ask for details on pumps and drainage equipment and a minimum rated capacity to expect. A sump pump rated at six thousand litres per hour or higher is a reliable benchmark for small to medium properties. Verify existence of backup power to run pumps and a plan for fuel or battery duration during extended outages.
Insurance documents to request
Ask the host to provide a copy of the property insurance policy showing flood related coverage and the policy expiry date. Confirm whether the policy covers structural damage and contents loss and whether guests have any right to claim for personal items. Request contact details for the insurer and the local claims agent and a simple summary of how a claim was handled in any prior flooding event.
Emergency plan staff and local response
Evacuation route and assembly point
Ensure there is a clearly described route to higher ground a safe assembly point and estimated travel times under normal and wet conditions. Ask staff to demonstrate the route if possible.
Contact list and escalation steps
Obtain a short list of staff emergency contacts local pump technicians and nearest medical and emergency services. Ask the host to outline who will coordinate on site and the sequence for contacting outside help if the situation worsens.
Collect written confirmations or dated photos for every promise and keep them with your booking papers. Clear documentation makes a one month stay more secure and gives you practical options if heavy weather arrives.
