I understand the Question refers to housing estates relying on Developer Provided Infrastructure (DPI) for their water services.
Funding is provided by my Department under the Multi-Annual Developer Provided Water Services Infrastructure Resolution Programme to progressively resolve issues with DPI across the country.
Funding of €68.5 million has been allocated, under the National Development Plan, for the period 2021-2025, to resolve these issues (this sum includes a small allocation for domestic lead pipe remediation).
I have approved funding of over €18m for projects under the programme to resolve issues in locations across the country that enables to estates concerned be taken in charge.
I can confirm that from 1 January 2024 Uisce Éireann, as the national water authority, have assumed responsibility for the remediation of DPI infrastructure.
