Note that you need to be on the quest Balance Must Be Preserved before it will drop. It is a followup from Disturbance at Umbrafen Lake available from the NPC [npc=17841] at level 61.
Even though the questitem says only level 59 is required, you still need a quest which is level 61 minimum.
After reading most of the comments I thought I couldent get the quest item anymore sense I had already completed the quest they say is required to get the item to drop. But while I was doing a Sporeggar quest I pulled a bunch of mobs and killed them. The schematic dropped but not off an overseer ( I have previously finished the Pump quest). I dont know what to make of it. Mine dropped off a Naga Enchantress North of Sporregar.

The schematics you've obtained show an underground system of drains and pumps that connect the lakes in the region to Serpent Lake. If the schematics are correct, there is a giant drain in the center of Serpent Lake. Confirm this and bring the news to Cenarion Refuge.
Where to go
Pins are the quest’s own POI points from the current retail client, projected onto the in-game zone map. The game marks one blob as the quest’s turn-in; the rest are objective areas. Points that fall outside a map’s window are dropped rather than guessed at.

Where this quest fits
Before this quest
Taken from the storyline's own step order.
- Balance Must Be Preserved
I cannot begin to comprehend why the naga would drain the water out of their own habitat. What I do understand is a need to put a stop to their operations. These seeds carry with them the rage of the earth. Take them to the steam pumps operated by the naga and use them on their controls.
After this quest
Taken from the storyline's own step order.
- Warning the Cenarion Circle
The Cenarion Expedition has become a large organization with a good degree of autonomy. These events are important enough that we need to warn the Cenarion Circle. Do not worry, I will not ask you to travel back to Moonglade; we have emissaries as nearby as Hellfire Peninsula.
