Recycling Treated Municipal Wastewater for Industrial Water Use

Section 3
Inventory of Major WWTPs and Potential Industrial Reuse Demands
As discussed throughout this technical memorandum, the factors that promote and
result in a water reuse application are very site specific. The inventory of industry
water demand and WWTP supply has been evaluated with broad criteria in this
document: ground water quality and quantity, pollutant discharge limitations for
receiving streams, industry diversity, available supply to meet demand, and the
WWTP capacity and location. Under Task 2 of the project, the evaluation of
wastewater reuse opportunities in Minnesota will expand to consider treatment
requirements, new facility construction, operation and maintenance needs, costs, and
the range of issues associated with implementation of facilities and practices to use
treated, municipal for beneficial uses.
