Design Risk Assessment for Wastewater
Infrastructure Standard Details
Connections and Developer Services Construction Requirements for Self-Lay Developments December 2017 (Revision v4.01)
Document IW-CDS-5030-02
IW-CDS-5030-02 Rev. v4.01 December 2017
Background Technical Documentation has been developed by Irish Water’s Connection and Developer Services which outlines the requirements for wastewater services infrastructure within developments. Standard details have been developed to outline Irish water’s requirements to developers in the provision of wastewater infrastructure that is to be installed in developments and that would be connected to Irish Water’s networks and subsequently vested in Irish Water. The aim is to provide details to developers for wastewater infrastructure, which will outline design and construction requirements to ensure consistency in the provision of materials, equipment and workmanship, etc. The standard details will also provide the basis for developers’ detailed design proposals for wastewater infrastructure, leading to the provision of infrastructure that is suitable for connection to Irish Water’s networks and easy operation and maintenance of the new infrastructure. The standard details are based on best practice within the water industry. They take account of the experience of Local Authorities in the provision of these services to new developments. They have been successfully used by Irish Water’s own internal functions for a variety of projects and they are in line with water utility industry norms. There are 36 No Standard Details dealing with wastewater infrastructure covering all aspects of such infrastructure. The standard details for wastewater infrastructure are contained in Document Number IW-CDS-5030-01. Design Risk Assessments (DRA) have been prepared to outline the residual health and safety responsibilities of developers and their designers/contractors in the provision of infrastructure in accordance with the standard details and these are included in Document No IW-CDS-5030-02. The residual risks outlined herein shall be taken into account in the detailed design of wastewater infrastructure. .
Design Risk Assessment For
Wastewater Standard Details
The Standard Details show the acceptable typical details and outline the minimum
standards that are required by Irish Water for the provision of wastewater pipes and
related infrastructure which are to be connected to the Irish Water Network. The
Standard Details shall be used in conjunction with the Design Risk Assessment that
has been developed which identifies the risks that designers shall take into account
in the detailed design of the wastewater pipes and related infrastructure to be
connected to the Irish Water Network. The pipes and related infrastructure to be put
in place within developments shall comply fully with these Standard Details. Ultimate
responsibility (including, but not limited to, any losses, costs, demands, damages,
actions, expenses, negligence and claims) for the detailed design, construction and
provision of such pipes and related infrastructure shall rest entirely with the
Developer, his/her Designer(s), Contractor(s) or other connected party. Irish Water
assumes no responsibility for and gives no guarantees, undertakings or warranties in
relation to the pipes and related infrastructure to be provided in accordance with
these Standard Details.
