Recycling Treated Wastewater For Industrial Water Use in Minnesota MCES Project 070186 / LCMR 05-07d 4/24/07 Water Reuse for Minnesota Industries – Implementation Considerations Discussion with Stakeholders, April 24, 2007 Topic Key Points Potential Actions Partnered Project • Projects initiated, reviewed and documented by the various stakeholders will provide a resource that will encourage water reuse practices. Economic Incentives • Incentives are needed to attract industries to use a reclaimed supply and municipalities to incorporate reuse in their WWTP practices. • Water reuse systems can be funded and operated by a variety of management structures – different options should be considered to provide the best incentives and optimize system costs. • Identify regulatory, industry, municipal wastewater utility, water utility, local community groups, and other partners to form a working group that is involved with the project(s). This group would walk “hand-in-hand” through the project and provide review and assessment of the project upon completion. • Projects can be case studies of the complete project process or focus on key features of water reuse projects, such as: public information programs, specific technologies, or regulatory guidelines. • Evaluate and promote the use of the Supplemental Environmental Project (SEP) program as a source of money for water reuse projects. • Recommend state grants (LCMR) for initiation projects with in-kind contributions by partnering entities. • Evaluate SRF project selection process to identify features that would encourage water reuse projects. • Consider a pollution tax credit for equipment used in a water reuse project.

Recycling Treated Wastewater For Industrial Water Use in Minnesota MCES Project 070186 / LCMR 05-07d 4/24/07 Water Reuse for Minnesota Industries – Implementation Considerations Discussion with Stakeholders, April 24, 2007 Topic Supply Issues Key Points Potential Actions • Reliability: A reclaimed supply can be the primary supply, backup supply or supplemental supply for an industry. The management of multiple water supplies must be considered in the facility infrastructure and processes, the storage requirements to meet variable demand patterns, and related permit requirements. • Dual Systems: Future development should consider dual water systems (potable and reclaimed supplies). • Water Quality Data: There are insufficient data available on the WWTP effluent from most municipalities. This makes it difficult to assess the treatment requirements and associated costs that would be needed to use a reclaimed supply. • Water Sampling to Assure Permit Compliance and Acceptability for Intended Use: The potential unknown contaminants that could occur in a municipal WWTP effluent and the concern for industry process problems and discharge permit compliance will require additional sampling to assure established water quality goals are met. • Establish a funded program for analysis of municipal WWTP effluent for parameters of concern for water reuse applications. This program could target WWTP with highest benefits for reuse and establish a historic data base for water quality that can be referenced in the planning for water reuse projects. • Incorporate reliability, water sampling, and other supply consideration issues as key elements of study in a ‘partnered project’.

<strong>Water</strong> Reuse <strong>for</strong> Minnesota Industries – Implementation Considerations<br />
Discussion with Stakeholders, April 24, 2007<br />
Topic Key Points Potential Actions<br />
Partnered Project • Projects initiated, reviewed and documented<br />
by the various stakeholders will provide a<br />
resource that will encourage water reuse<br />
practices.<br />
Economic<br />
Incentives<br />
• Incentives are needed to attract industries to<br />
use a reclaimed supply and municipalities to<br />
incorporate reuse in their WWTP practices.<br />
• <strong>Water</strong> reuse systems can be funded and<br />
operated by a variety of management<br />

optimize system costs.<br />
• Identify regulatory, industry, municipal<br />
wastewater utility, water utility, local community<br />
groups, and other partners to <strong>for</strong>m a working<br />
group that is involved with the project(s). This<br />
group would walk “hand-in-hand” through the<br />
project and provide review and assessment of<br />
the project upon completion.<br />
• Projects can be case studies of the complete<br />
project process or focus on key features of<br />
water reuse projects, such as: public<br />
in<strong>for</strong>mation programs, specific technologies, or<br />
regulatory guidelines.<br />
• Evaluate and promote the use of the<br />
Supplemental Environmental Project (SEP)<br />
program as a source of money <strong>for</strong> water reuse<br />

entities.<br />
• Evaluate SRF project selection process to<br />
