Recycling Treated Municipal Wastewater for Industrial Water Use

Section 1
Introduction
1.5 Document Contents
This technical memorandum presents background information on the project and
water reuse in general, implementation considerations, and an inventory of the
industrial water demand and supply of treated wastewater.
Section 1: Presents the project vision, drivers for water reuse in Minnesota, general
water use in Minnesota in context with water used by industries, and an overview of
reuse practices and specific wastewater reuse issues for Minnesota.
Section 2: Provides an overview of considerations for the industry and municipal
supplier that affect the implementation of a water reuse project. Regulatory, technical
and institutional issues are identified to educate the stakeholders on the diversity of
issues that must be addressed for successful implementation and operation of
wastewater reuse facilities.
Section 3: Reviews the historical water use in the state for major industrial users in
context with municipal WWTPs’ location and production capacity. A more in-depth
review of industry water demand and municipal WWTP supply is provided for each
individual watershed. General information on the existing water sources in the
watersheds and areas that may be prone to water supply problems is also provided.
The Minneapolis/St. Paul metro area is examined on a WWTP basis, where industries
located within a one- and five-mile radius of each existing metro-area WWTP are
identified. The section concludes with a summary of industrial water use demand in
context with the supply of reclaimed water.
