Other examples provided include our partnership in a Hennepin County U2 Framework designed to 
improve collaboration on infrastructure investments and construction among public and private entities 
to minimize disruption and reduce costs to the public.  We also provided $1.5 million for regional water 
efficiency and regional stormwater reuse grants to encourage watershed districts and communities to 
invest in community assets, with an emphasis on equity, and reduce demands on groundwater.  The 
grant programs have resulted in the conservation of more than 90 million gallons of water annually.   
Energy Efficiency 
MCES has completed or have underway all of the standard activities listed, plus several more that are 
being implemented.   We have reduced energy consumption by 260,000 MMBTU/yr since 2006, and 
leadership has established a goal to reduce fossil fuel based energy purchases by 10^ from 2015 to 2020 
through both energy reductions and increasing use of renewable energy sources.  This is accomplished 
by partnering with our energy utility, through the work of an internal Energy Team, replacement of 
facility lighting fixture with more energy efficient fixtures, continued implementation of an aeration 
efficiency program and many other activities. 
Energy Generation and Recovery.   
MCES has completed or has underway all of the standard activities listed, plus several more than are 
being implemented.   Leadership has established a goal to reduce fossil fuel based energy purchases by 
10^ from 2015 to 2020 through both energy reductions and increasing use of renewable energy sources.  
We are currently participating in solar photovoltaic projects that will generate about 10 MW of solar 
energy.   In addition, steam generated from incineration at Metropolitan Plant, our largest, is used to 
generate energy or provide heat to buildings. Anerobic digestion added at another of our plants 
produces gas that replaces 9 million BTUs an hour of natural gas demand,   and the future installation of 
a 1000kW combined heat and power will convert the plant’s digester gas to electricity.  
Water Reuse 
MCES has completed or has underway all of the standard activities listed, plus several more that are 
planned or being implemented.  We currently reuse highly-treated effluent (reclaimed water) from its 
East Bethel Water Reclamation Facility and since 2014 0.024 mgd has been used to recharge 
groundwater or augment surface water via subsurface infiltration basins.  We are engaged in feasibility 
studies with water suppliers to develop concepts and costs for wastewater reuse and to move concepts 
to implementation, and are leading by example by reusing about 8 mgd of wastewater onsite.  .Another 
highlight is that MCES is completing a one year or more sampling study to determine the quality of our 
effluent and underdrain dewatering water in order to evaluate suitability for reuse.   
Watershed Stewardship 
MCES has completed or has underway all of the standard activities listed, plus several additional that are 
listed.  From 2005-2015, communities in the region completed $145M in Infill and Infiltration (I/I) 
mitigation projects in their municipal wastewater collection systems.  Also, MCES spent $88M on I/I 
mitigation in our own system from 2007-2015 and we plan to make an additional $72M in mitigation 
through2019.  Metered flows are showing a downward trend it both base flows and peak hourly flows 
during wet weather events, and it appears the regional will avoid the unnecessary expenses, estimated 
at $1.5 Billion to build  capacity  in the system to handle excess I/I.  
The installation of numerous green infrastructure improvements at one of our plants, including a green 
roof, permeable pavers, infiltration basins and restored wetlands and other features has resulted in the
