Pump System Report is a book found in The Knife of Dunwall.
Log Entry: Standing water, not more than ankle deep. Something must be blocking the drainage.
Log Entry: Drainage was cleared and the standing water isn't an issue any longer. Note: Pump system may be insufficient for high-volume situations.
Log Entry: Waist-high water, drainage problems again. The accountants are going to have to swim to work if something isn't done about the pump system.
Log: Last day in Rudshore: my new post starts tomorrow. I've restated my concerns about the pumps. I suggest my replacement check the valve pressures and system mechanical integrity immediately.
