You need "The Watergod's Altar" quest. Set it as your priority, go there, then defeat the Cyclops in the main hall of The Watergod's Altar. In turn, he drops the key which is a red Misshapen Eye-looking item. Use the key at that door and you'll get access to a passage that will provide the water draining pressure plate.

If you don't have the quest, you get it by speaking to the knight just outside the gate leading to the duke of Gran Soren, after completing the Everfall quest given by Barnaby at the Pawn's Guild. When you complete Everfall, a knight gives you a Wyrm Hunting License which allows you to speak to that knight outside the duke's gate and take on a variety of quests. The Watergod's Altar quest is the option of "aiding a research team".

Hope this helps.
