State of the State is………..
• Aging and failing infrastructure
• No source of sustainable funding
– User fees have been set below full cost of
sustainable operation
– Results in insufficient financial resources
available
• Increased regulatory requirements
add significant costs
• Climate Change
Case Study - City of Manchester
• Largest City North of Boston - 109,000 population
• Settled in 1725
• Evolved from Agricultural
to Industrial: 1725 - 1815
• Amoskeag Mills: Largest
single mill in the world 1915
• Post Industrial Depression: 1935 – 1980’s
• Revitalization: 1990 to Present
• Revitalization = “ManchVegas”

Manchester’s Water Infrastructure
Pipes, Pump Stations, and Reservoirs
•
•
•
•
500 miles of pipelines
9 Pump stations
5 Storage tanks
2 Reservoirs
“State of the City”
• Greatest amount of water infrastructure in the
state
• Aging and failing infrastructure
– Over 200 miles of pipe over 100 years old
• Systems stressed
– Not designed for this population
– Not designed for new regulations
– Not designed for this amount of impervious area
– Not designed for climate change
“State of the City”
• Investments in critical infrastructure
– WTP upgraded in 2006 - $32 million
– WWTP upgraded in 2014 - $22 million
– WWTP programed for $30 million over next 10
years
“State of the City”
• Capital Improvements Ongoing
– Two new water storage tanks ($8 million)
– Cohas Brook Sewer Project to Protect Lake
Massabesic and Cohas Brook watersheds
– $25 million over 10 years
– 4 contracts, service to over 1,000 homes
– CSO Abatement
– Phase I: West side 1999 to 2009 $58 million
– Phase II: East side 2012 to 2032 $165 million
– Phase III: East side 2032 to 2052 $200 million
“State of the City”
• Water and wastewater utilities are pro-active
in maintenance
– Cleaning/lining water mains ($0.50 million
annually)
– Water main replacement ($1.5 million annually)
– CMOMs ($1.5 million annually)
State of the City - Challenges
• Insufficient funding to fully address aging and
failing water infrastructure needs
• Increased regulations requires significant
additional funding
– Nutrients, metals, MS4
• Climate change
– Four “100 years storms” since 2005
• “Greying of the industry”
– Need to capture institutional knowledge
– Need qualified and passionate professionals
Conclusions
• NH is “water rich” but our infrastructure is
among the oldest in the country
• Need a sustainable funding source to assist
communities in addressing one of NH’s most
valuable resources, our water infrastructure
Conclusions
• Not a NH problem – A National Problem
– California Proposition 1
– $7.2 million bond
– Leverage to $25 to $30 billion
– Their infrastructure only dates back to 1930s
