Raw water distribution EN-CV limit of supply Piping to the demi water skid heat exchanger

Demi water production Interface with the demi water distribution. Demi water distribution At the present time, the demi water distribution details are not defined yet. The integration effort is ongoing.

Procurement and Planning Full blown CERN tender procedure for Raw water production, distribution and Demi water production. Market Survey dispatched mid September, – MS-4047, EDMS N o : IT to be dispatched by mid November, 2014 The contract is foreseen to be awarded in April 2015 after Finance Committee approval in March Demi water distribution to be done within the framework of EN-CV small jobs contract or via an amendment of the main contract. System fully operational by December 2015.
