Water in Johor is supplied by Ranhill SAJ. Households with their own meter pay RM1.05 per cubic metre for the first 20 m³, RM2.35 for 20–35 m³ and RM3.50 above 35 m³ (after a 35 sen increase from 1 August 2025), with a minimum charge of RM10.50 a month. Scheduled disruptions are announced at least 24 hours ahead on Ranhill SAJ’s website and social media, and new owners or tenants open an account at a Ranhill SAJ counter with their NRIC and S&P or tenancy agreement.
Moving into a JB condo raises a set of small but important questions. Who supplies the water? How much will the bill be? What happens when there is a water cut, and how do I put the account in my name? This guide answers them with Ranhill SAJ’s own published rules and recent news coverage, so owners, tenants and landlords know what to expect from day one.
Who supplies water in Johor Bahru?
Ranhill SAJ Sdn Bhd is the licensed water operator for the whole of Johor, including JB. It treats and distributes water, reads meters, bills customers and handles disruptions. Electricity, by contrast, comes from TNB, which we cover in our TNB electricity tariff guide.
Most of what you need is handled through three channels: the MySAJ 2.0 mobile app, the Ranhill SAJ website, and the toll-free hotline 1800 88 7474.
Ranhill SAJ water tariffs: how much will I pay?
Domestic water is cheap by regional standards, and most households stay in the two lowest bands. Rates were revised on 1 February 2024, and on 1 August 2025 only the top band and bulk meters went up.
| Domestic category | Rate per m³ | Notes |
|---|---|---|
| Individual meter, 0–20 m³ | RM1.05 | Unchanged in Aug 2025 |
| Individual meter, 20–35 m³ | RM2.35 | Unchanged in Aug 2025 |
| Individual meter, above 35 m³ | RM3.50 | RM3.15 plus 35 sen from 1 Aug 2025 |
| Individual meter, minimum charge | RM10.50 a month | Unchanged |
| Bulk meter (strata), flat rate | RM2.75 | RM2.55 plus 20 sen from 1 Aug 2025; minimum RM25.50 in the 2024 schedule |
Ranhill SAJ said tier one and tier two users make up most domestic accounts in Johor, so the 2025 change left most households’ rates unchanged. One cubic metre is 1,000 litres.
What this means for you: a couple in a 2-bedroom unit who stay within 20 m³ a month pay the lowest rate on every unit. Usage only gets noticeably more expensive above 35 m³, which is more typical of large families or a leaking toilet cistern.
Individual meter or bulk meter?
Some strata buildings take water through one bulk meter and the management body then bills each unit from sub-meter readings. Others have an individual Ranhill SAJ meter for every unit. Ask the management office which applies to your building, because it decides who you pay and which rate you see.
How do I set up a water account as an owner or tenant?
New accounts and changes of name are handled at Ranhill SAJ counters, and the deposit and charges depend on the premises type. Your licensed plumber can submit a new supply application for you.
| Applicant | Documents listed by Ranhill SAJ |
|---|---|
| Owner | Copy of NRIC; witness’s NRIC; S&P agreement; land title (for new supply, also the CCC or tax assessment) |
| Individual tenant | Copy of NRIC; witness’s NRIC; tenancy agreement; statutory declaration, owner’s confirmation letter and supporting letter; property tax assessment |
| Company tenant | Applicant’s IC; tenancy agreement and property tax assessment; SSM certificate; Forms 24 and 49 |
- Fill in the application form and print the Services Agreement from the Ranhill SAJ website.
- Submit them with your documents at a Ranhill SAJ counter.
- Once approved, pay the deposit, stamp duty and any connection charges.
- For a new individual meter, Ranhill SAJ says installation takes place within two working days of paying the deposit.
Ranhill SAJ does not publish fixed deposit amounts on these pages, so confirm the figure at the counter or on the hotline before you go.
Tips for landlords
Many landlords keep the water account in their own name and ask tenants to reimburse actual usage, as with electricity. It saves repeated paperwork between tenancies. Record the meter reading at move-in and move-out, and state in the tenancy agreement who pays the bill and by when. Our property management guide for JB covers handover checklists in more detail.
Water disruptions: how often, and how do I get notified?
Most disruptions in JB are scheduled maintenance or pipe work, and Ranhill SAJ commits to giving at least 24 hours’ notice through its official social media channels, with updates on its website.
- Follow Ranhill SAJ on its official social media and check the website’s announcements.
- Install the MySAJ 2.0 app to manage your account and bills.
- Call 1800 88 7474 to report a disruption, burst pipe or low pressure.
- Join your condo’s residents’ group, where management usually relays notices quickly.
Planned works can be lengthy. In July 2025, maintenance at the Sultan Iskandar Water Treatment Plant in Pasir Gudang caused a scheduled 26-hour cut affecting more than 30,000 accounts in parts of JB, including Tebrau, with water tankers sent to hospitals, dialysis centres and other critical sites.
Water tanks and storage in condos
High-rise condominiums store water in building tanks and pump it up to the units, which can help smooth out short interruptions. How long that storage lasts depends on the building’s design and how much residents use during the cut, so it is sensible to prepare for scheduled disruptions anyway.
- Fill a few containers for drinking and cooking before a scheduled cut.
- Avoid heavy use such as laundry while supply is limited.
- After supply returns, run the taps briefly if the water looks cloudy.
- To check for hidden leaks, Ranhill SAJ suggests noting your meter reading at night when no water is in use and comparing it the next morning.
How do I pay my water bill?
Bills are typically monthly. Ranhill SAJ accepts payment through the MySAJ 2.0 app, its website, JomPAY (biller code 3673), online banking, Ranhill SAJ counters and PayQuick kiosks, 7-Eleven, Pos Malaysia counters in Johor and other agents.
But what if my bill is suddenly much higher? Ranhill SAJ points to two usual culprits: an overflowing tank or an internal plumbing leak. Run the overnight meter test above first. If the meter moves while nothing is in use, call a plumber; a running toilet cistern is a common cause. If the meter is steady and the bill still looks wrong, contact Ranhill SAJ, which also offers meter testing on request. For landlords, a quick check of the bill each month is the easiest way to spot a leak in a tenanted unit before it becomes expensive.
