Potential and Strategies for

Campus Water Reuse

All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.

------ Arthur Schopenhauer

Setting The Stage … WHY ?

"The earth belongs to the living. No man may

by natural right oblige the lands he owns or

occupies to debts greater than those that

may be paid during his own lifetime. Because

if he could, then the world would belong to

the dead and not to the living."

Thomas Jefferson

Yeah … BUT

Obstacle/Strategies: Public Utility –

Partner, Collaborator, or

Adversary? Centralized vs Decentralized

Very Situational

Partner vs Adversary

Win – Win Necessary

You want to put WHAT on my campus?!?

Decentralization Creates New Dynamics: Safety, Aesthetics & Footprint

VS.

Obstacle/Strategies: Aesthetics Good neighbor in tight spaces

Natural Systems

Odor Control

Early involvement and attention

Hydroponics with Submerged Fixed Film Media

A Natural Habitat is Utilized to Break Down Waste

Plant Racks

Aeration Grid

Root Zone

Textile Media

MBBR

Obstacle/Strategies: Footprint Small Footprint Systems – MBBR, MBR,

IFAS

Flexibility to work in disjointed spaces

Flexibility to scale or network

Obstacle/Strategies: WQ Fear Same thing, only different

Early involvement of staff and 3rd parties

Obstacle/Strategies: Capex/Funding Alternative Delivery – DBO, DBOO/WPA

Negotiated Turnover/Assumption

Flexibility in approach

The Lessons Opportunity Abounds

Perspective … its not recognized by

everyone

Nor viewed similarly by everyone

So Listen Now, or talk/convince/defend a

LOT more later

Stretch a lot, you’ll need flexibility

Pace yourself, it’s a marathon not a sprint

“It’s a little like wrestling a

gorilla. You don’t quit when you

get tired - you quit when the

gorilla gets tired.”
