Swimming pools at the NSC will be closed for nine months whilst extensive refurbishment works are carried out.
?4.2 million will be spent updating the competition and leisure pools which are 20 years old.
The facility will close on August 4th and is set to re-open in May next year.
Education, Sports and Culture Minister Graham Cregeen says: "I welcome this significant investment in one of the Island’s key sports facilities which demonstrates government’s commitment to sport.
"The Programme for Government sets out a number of targets around health and wellbeing: such as increasing the number of people regularly undertaking physical exercise, and increasing healthy life expectancy.
"Access to sports facilities plays a key role in realising these ambitions.
"The Island has invested considerably in sport over the past 25 years and we continue to reap rewards from this."
A new zero-depth wet play area will be created as part of the revamp – the changing areas will also be fully refurbished.
