Combined Sewer Overflow Committee
GOAL: Smart Combined Sewer Overflow (CSO) Plans
Municipalities and utilities adopt innovative CSO Long Term Control Plans (LTCPs) with cost-effective
solutions that meet or exceed permit requirements and provide multiple community benefits.
4.1 Balancing Pipes and Parks
LTCPs incorporate and commit to an optimized balance of green and gray infrastructure to achieve the
goals of the Clean Water Act.
4.2 Reducing Combined Sewer Flows
LTCPs prioritize proven approaches that reduce combined sewer system flows, such as inflow and infiltration (I & I) reduction, green stormwater infrastructure and water conservation.
4.3 Serving Host Communities
Implementation of the LTCPs reflects early input of community stakeholders and delivers significant additional community benefits including improved public health, green space, economic revitalization and local jobs.
4.4 Affordable Combined Sewer Overflow (CSO) Solutions
CSO LTCPs help ensure affordability for all ratepayers by using cost-effective overflow-reduction
strategies, state and federal funding assistance, equitable rate structures, innovative financing mechanisms, appropriate implementation schedules and leveraging of other public and private investments.
