    I haven't dug through it yet. It's officially being released tomorrow (the 26th), but it looks like they've already posted it on the website. Hopefully this isn't a repost. I haven't seen anyone else post this, but I may have missed it.

    Link to the actual study:

    It looks like some of this will be no surprise to people who have read a lot on the topic or are knowledgeable in the area. Note, I'm not claiming I am knowledgeable.

    Just a couple points I've picked out so far:

    Toilet paper performance was a significant variable.

    They had issues with 0.8 gpf performance. This is on page 47.
    They found that 1.28 and 1.6 gpf was sufficient, if the drainline was in good condition. This is on page 48.

    BTW, we have already started seeing a problem in buildings with extended drain lines and not enough water to move solid waste.
