I/I Policy and Strategy

Infiltration/Inflow Program— 2000-2002: Problem identification— 2003-2004: I/I Task Force— 2005: Water Resource Management

Policy Plan

Page 6: Metropolitan Council Environmental Services A Clean Water Agency Presented to the Environment Committee January 13, 2009 Inflow/Infiltration (I/I) Program.

I/I Policy and Strategy

Water Resources Management Policy Plan— Infiltration/Inflow Policy

– The Council will not provide additional capacity to serve excessive infiltration/inflow (based on design flow standard)

Page 7: Metropolitan Council Environmental Services A Clean Water Agency Presented to the Environment Committee January 13, 2009 Inflow/Infiltration (I/I) Program.

I/I Policy and Strategy

Infiltration/Inflow Program— Communities implement infiltration/inflow

reduction programs to achieve compliance with Council design flow standard by 2012

— Starting in 2013, the Council will implement a wastewater demand charge for those communities that have not achieved compliance

I/I

Demand Charge

= a community-specific charge for excess capacity demand

Page 30: Metropolitan Council Environmental Services A Clean Water Agency Presented to the Environment Committee January 13, 2009 Inflow/Infiltration (I/I) Program.

I/I Background Facts

Required by Water Resources Management Policy Plan (WRMPP)

“Starting in 2013, the Council will institute a wastewater rate demand charge program for those communities that have not met their inflow and infiltration goal(s).” (p. 40)

Impacts community I/I efforts now

We said we’d have a public process for developing the Demand Charge details

Minneapolis asked for 3-year notice of how the Demand Charge will work

Page 31: Metropolitan Council Environmental Services A Clean Water Agency Presented to the Environment Committee January 13, 2009 Inflow/Infiltration (I/I) Program.

I/I Development Options

1. Begin development process now and implement in 2013

2. Begin development of charge now but reconsider implementation date

3. Delay development and implementation

Requires changing WRMPP

Page 32: Metropolitan Council Environmental Services A Clean Water Agency Presented to the Environment Committee January 13, 2009 Inflow/Infiltration (I/I) Program.

I/I Develop Demand Charge

Community Task Force?— Develop goals/criteria of charge

Hire consultant— Review similar charges across other metros— Identify feasible designs— Analysis of design

Consider need for legislation

Page 33: Metropolitan Council Environmental Services A Clean Water Agency Presented to the Environment Committee January 13, 2009 Inflow/Infiltration (I/I) Program.

I/IDelay Implementation of Demand Charge

Why?— Success of local programs gives MCES

ability to delay— Capital Project decisions for some growth

projects are being deferred— Cities are under a lot financial pressure with

declining property values and local government aid (from State)

Page 34: Metropolitan Council Environmental Services A Clean Water Agency Presented to the Environment Committee January 13, 2009 Inflow/Infiltration (I/I) Program.

I/I Recommended Next Steps

Establish a Task Force

Begin review of Demand Charge (decision on implementation date can wait)
