Water is essential to the lifestyle, environment and economy of Esperance. From supplying homes and businesses to supporting wetlands, lakes, parks, gardens and local agriculture, groundwater plays a vital role in the region.
Esperance relies heavily on groundwater as its primary source of drinking water. Most of this water comes from the shallow Superficial aquifer, a narrow coastal groundwater system that supports both public water supplies and private use.
Our research has shown groundwater abstraction and changing climatic conditions are contributing to rising salinity in parts of the aquifer. Because Esperance is located along the coast, with salt lakes to the north, there is a delicate balance between fresh groundwater and saltwater beneath the ground. Maintaining this balance is critical to protecting water quality and ensuring reliable water supplies for future generations.
This page brings together information and resources about groundwater management, drinking water protection, water restrictions, rural water supplies and practical ways you can help conserve water. Whether you are a resident, bore owner, business operator or interested community member, the resources below will help you better understand Esperance's water challenges and how you can contribute to sustainable water use.
Together, we can help protect Esperance's precious groundwater resources and ensure a sustainable water future for the community.
New watering arrangements for domestic bore users
From 1 December 2026, a two-day per week sprinkler roster for domestic bores will commence for the whole of Esperance Shire, plus the locality of Munglinup.
This change aligns with the existing two-day per week watering days arrangements which are already in place for scheme water customers, who will not be impacted by this change.
Sprinkler Switch Off
From 1 June 2027, a Sprinkler Switch Off will be introduced across the whole Esperance Shire, plus the locality of Munglinup.
This means sprinklers must not be used during June, July and August, when rainfall is typically higher and less outdoor watering is needed.
Why are the domestic bore watering changes being introduced?
The new domestic bore watering arrangements are designed to help reduce pressure on local groundwater resources and support Esperance's long-term water security.
