Water bills… landlord’s job or tenant’s responsibility?

Water supply

Landlords must ensure the property has a reliable water supply. If there’s no town (piped) water connection, it’s the landlord's responsibility to provide a system that collects and stores sufficient water, such as tank supply.

For properties within a unit-title complex, any body corporate rules related to water supply or charge allocation become part of the tenancy agreement. Landlords should make tenants aware of these rules before the tenancy begins.

Fixed water charges

Water suppliers often charge a fixed fee regardless of consumption. Who pays depends on how the supplier bills:

  • If the fixed charge applies regardless of whether the property is occupied, the landlord is responsible.
  • If it only applies when someone is living at the property, the tenant may be responsible.

Metered usage and wastewater

If water is billed based on actual consumption and the property has its own separate meter, tenants are usually responsible for water use. This only applies if the charges can be clearly linked to the tenant’s usage.

Some suppliers calculate wastewater based on metered water. In those cases, landlords can pass on wastewater charges to tenants if it directly relates to their water use.

Under the Residential Tenancies Act, tenants are only required to pay for outgoings when they are exclusively attributable to their occupancy and usage.

How billing should be handled

The water account must remain in the landlord’s name. The landlord pays the supplier directly and then recovers any tenant-related charges. Best practice is to send the tenant a copy of the bill (with personal information removed) when requesting reimbursement.

Some water suppliers, with landlord approval, can provide a copy of the bill directly to the tenant.

If payments aren’t made

If water is disconnected because the landlord did not pay the account, it is the landlord’s responsibility to restore the connection.

If the tenant fails to pay their portion after being invoiced, this is a breach of the tenancy agreement. The landlord may issue a notice to remedy. If it remains unpaid, the matter can be escalated to the Tenancy Tribunal.

Tank water properties

Where the property relies on tank water, the landlord should provide a full tank at the beginning of the tenancy. The tenancy agreement should clearly state that the tenant will arrange and pay for any refills during the tenancy.

Landlords are responsible for ensuring the tank is suitable in size (typically 22,500L for an average home), properly connected for rainwater collection, and free from leaks and contamination. General pump maintenance is also a landlord responsibility unless damage results from incorrect tenant use, such as running the pump when the tank is empty.

Written instructions on how the tank system operates should be provided to the tenant.

Why clarity matters

For landlords, correctly managing water billing prevents disputes and avoids issues that may lead to Tribunal action. For tenants, understanding what you’re required to pay helps prevent unexpected costs.

Property managers play an important role in ensuring these responsibilities are clearly outlined in the tenancy agreement from the start.
