cincinnati's approach for a city of the future
DESCRIPTION
The Metropolitan Sewer District of Greater Cincinnati (MSDGC) is using a watershed-based approach for wet weather management and water quality improvements - approaches that consider existing conditions, leverage additional resources and investments, and develop “factor conditions” to support communities of the future. Focusing on a direct enabled and “inform & influence” strategy, as well as source control, MSD has developed an approach to evaluate sustainable infrastructure and systems opportunities within the service area. The goal is to provide: cost effective water quantity management, water quality improvement, and community enhancements.TRANSCRIPT
Communities of the Future:
Cincinnati MSD’s Approach to Align Economies, Communities & the
Environment for maximum benefits
October 4, 2011
Tony ParrottExecutive Director
MSD of Greater Cincinnati
MSD Background• Population Served
• 850,000 in Hamilton County, Ohio• 220,000 connections
• Double Governance• Hamilton County Sewer District• City of Cincinnati
MSD Current Environmental Challenge
MSD is among the Top 5 CSO dischargers in the US3
What’s the Challenge?
Cincinnati is one of 772 cities in the United States with a combined sewer system.
Consent DecreeThe Consent Decree mandates that MSD:
(1) Capture, treat, or remove annual overflows from CSOs to a minimum control of at least 85%
(2) Eliminate all sanitary sewer overflows (SSOs)

Business Case for Wet Weather Strategy
Real Time
Control
• Low cost/gallon removal• Limited opportunity – 4 locations within Lower Mill Creek: installation
complete• Estimated reduction of approximately 610 MG (400 MG credited towards 2 BG)
Storage,
Conveyance & Treatm
ent
• High Capital Cost - Phase 1 Tunnel (7600 ft) to capture 1.6 BG• High O&M Cost: pumping & treating large volume of stormwater
Source Control
• Lower cost/gallon removal• Strategic focus on large scale opportunities • Lowers future O&M cost by removing stormwater from pumping & treatment• Improves water quality and increases natural drainage to Mill Creek

Focus on the Lower Mill Creek Watershed
MSD is focusing on watersheds within the Lower Mill Creek that experience high volumes of combined sewer overflows (CSOs).

DEPTH VS. VELOCITY EXAMPLES
• A rule-of-thumb for ‘safe’wading’ says that the product of velocity in feet/second times depth in feet should be less than 10 for safe wading in streams
5 fps (velocity) * 2 ft (deep) = 10
• A moderate sized person begins to lose stability at 2 fps in 3 ft of water
• Swift flowing water can knock a person down in depths of only 6 inches

Public Infrastructure Projects as Catalyst for Development• Creates jobs and business revenues for local contractors and tradesmen
working on sewer improvement projects;• Promotes the use of small, woman-owned, and minority businesses on
sewer improvement projects;• Increases property values in homes that previously experienced chronic
sewage backups requiring disclosure to prospective buyers;• Increases property values in areas that previously experienced chronic
overflows resulting in poor water quality after rains, odors, and sewer debris; and
• Promotes business growth - new business development or existing business expansions - in the MSD service area through the creation of sewer connection credits.
