IRIS dominates this morning's House of Keys question paper.
Nine of the 19 questions are for chairman of the Water and Sewerage Authority, Tim Crookall MHK, about various aspects of the scheme, including capacity and costs.
All nine come from Onchan MHK Peter Karran, although as they appear in the latter half of the question paper, he might not get responses to all of them in the chamber this morning.
Topics in the other 10 questions include government financing of Manx Gas infrastructure, the impact of the UK emergency budget on the Isle of Man and public sector housing for returning armed forces personnel.
There's also a request for the former Transport Minister, David Anderson, to make a statement on the footpaths at Langness.
Keys questions start at 10am this morning and are broadcast live on Manx Radio's AM 1368 frequency.
Meanwhile, in the Legislative Council Alan Crowe will be sworn in after being re-elected last week.
That's ahead of LegCo going over the Misuse of Drugs (Amendment) Bill, the Civil Partnership Bill and the Fisheries Bill.
