Around 900 customers in Douglas will see disruption to their water supplies overnight.
Manx Utilities says it will be moving some customers in the Douglas Promenade area onto a new mains system from Midnight with the work expected to be finished by around 4am tomorrow.
As a result, the authority says supplies in that area will be shut off during this time and could result in low pressure or no water at all.
All the properties in the affected area have been notified.
