• July 1987 superstorm

– 16” of rainfall over one week in region

• 1990 MCES system evaluation

– 20% of annual flow from I/I

• 2002 MCES interceptor master plan

– Future flow will exceed capacity; not sustainable

– More cost effective to address sources than build capacity

• 2004 I/I Task Force of communities

– Begin MCES I/I Program

– Incentive and resources for communities

– Revised 2010, 2016

Energy Reduction, Cost Savings• From 2008-2015, MCES has reduced energy

consumption 23%, savings of $4M annually

• The goal is to reduce energy consumption by 10% by

2020, saving an additional $1M annually.

Through other grants, rebates, etc., MCES has saved $7M

on energy costs.

Water Supply Planning – Minn. Stat. 473.1565

2005 Legislation

– “Carry out planning activities addressing the

water supply needs of the metropolitan area”

– Twin Cities Metropolitan Area Master Water

Supply Plan- 2010

Metro Area Water Supply Advisory committee

– Municipalities/utilities

– Counties

– State agencies

Purpose

– Assist and Guide Council water supply planning

– Approve Master Water Supply Plan (2015)

– Appoint Technical Advisory Committee (2015)

• Adequate water supplies are essential for

our region’s growth, livability and

prosperity.

• Met Council Role in Regional Water Supply

Planning – A regional water supply plan

– Support Local government units making informed and

effective decisions

– Assistance to communities in developing and

implementing local plans

– Identify approaches for emerging issues, and

– Strong collaborative relationship with stakeholders.

Planning Objectives for Regional Water Supply

The Metropolitan Council is

not a water supplier. Our

intent is not to take over

local water supply

systems. The regional

planning process has been

designed and applied to

ensure local water

suppliers have control of

and responsibility for their

water supply systems.

for a year

• Industries saved $1.1 Million a year in water and energy cost

• Municipal Water efficiency Grant Program (started 2016)• 19 recipients

• 85 Million Gallons of water Saved – enough water for 2,500 people for a year

What do Stakeholders say?

• The Metropolitan Council's Water Conservation Toolbox includes information and an extensive list of resources for residents who want to use their water efficiently. (City of St Louis Park)

• Being Able to start from Metro Model to construct the groundwater model used for the New Brighton WHPA delineation made the work more efficient and cost lower. (Grant Wyffels, Former Director of Public Works, New Brighton)

• The public awareness that the Program- efficiency Grant Program-creates is a benefit as we work to educate the public on the importance of conserving water, even In Minnesota.(Mark Burch, Director of Public Works, White Bear Lake)

• The Metropolitan Council plays a valuable facilitating role in the discussions and provides a regional perspective for the group. Council funding of Southeast study was important because it isn’t always easy to get local city councils to commit funds to something that reaches beyond their borders” Steve Albrecht .(Steve Albrecht, Director of Public Works, Burnsville)

Sewer Availability

Charge (SAC) Overview

Page 58: Metropolitan Council Wastewater Utility Overview

58

• The Sewer Availability Charge, or SAC, is a one-time fee

charged to local governments. (Some local governments also

add additional fees to the SAC.)

What is SAC?

• One single family home = 1 SAC unit

• Non-residential properties require a

determination (or calculation) of the maximum

potential wastewater capacity needed for the

site.

• The Council charges SAC to local

governments, who pass it on to business or

property owners.

time and generations.

• SAC future-proofs our

communities to grow

SAC serves the community

• Acts as a savings program: capacity built up front, users only pay

when additional capacity is needed

• Promotes regional growth: development can occur anywhere in the

region

• Frequent meetings with stakeholders to verify the program serves its

constituents

SAC is only for increased

capacity• SAC is only charged when a new or

existing business increases the

capacity demand on the system

• New construction

• Remodel adds more seats

• Remodel changes use to higher

demand (e.g., bookstore to

restaurant)

• There are programs to help small to

medium businesses defer the cost

of SAC
