PVSC’s Plan for Promotion of Green Infrastructure

• The PVSC Sewerage District

– 48 municipalities in 5 counties

– Includes both Separate and Combined Sewer Systems

• 9 with Combined Sewer Systems

• Combined Sewer Overflows (CSO)s and stormwater runoff can impact ambient water quality

– Can be partially alleviated with use of Green Infrastructure

• Green Infrastructure components will be required in CSO Long Term Control Plans

• PVSC is dedicated to leading efforts throughout the PVSC Sewerage District to: 1) intercept stormwater runoff 2) reduce Combined Sewer Overflows (CSOs) 3) manage existing water infrastructure 4) minimize frequent flooding events

• PVSC has entered into a partnership with Rutgers Cooperative Extension (RCE) Water Resources Program to achieve these goals

• Green Infrastructure Program (Year 1)

3 Main Objectives:

1) Municipal Outreach and Education

2) Community-Based Technical Assistance

3) Green Infrastructure Demonstration Projects

May – June 2013

– Initial Stakeholder meeting

– Development of educational materials and distribution to municipalities

– Kick-off Event @ PVSC (May 16, 2013)

– Program website to be developed and hosted by RCE Water Resources Program (http://www.water.rutgers.edu/PVSC.html)

Objective 1 – Municipal Outreach and Education

June 2013

What is stormwater?

Stormwater is the water from rain or melting snows that can become “runoff,” flowing over the ground surface and returning to lakes and streams.

WHAT IS A WATERSHED? ó An area of land that water flows across, through, or under on its way

to a stream, river, lake, ocean or other body of water. ó A watershed is like one big bathtub...

watershed is?

WHERE DOES PRECIPITATION GO?

1. It can run off

WHERE DOES PRECIPITATION GO? 2. It can be absorbed by plants and used for

photosynthesis and other biological processes

WHERE DOES PRECIPITATION GO? 3. It can infiltrate through the soil surface and percolate

downward to groundwater aquifers

WHERE DOES PRECIPITATION GO? 4. It can evaporate

More development

More impervious surfaces

More stormwater runoff

The Impact of Development on Stormwater Runoff

LAND USE/LAND COVER CHANGES

LAND USE HOW LAND IS USED BY

HUMANS: • AGRICULTURE • INDUSTRY • URBAN • RESIDENTIAL • RECREATION

LAND COVER BIOLOGICAL AND

PHYSICAL FEATURES OF THE LAND:

• FORESTS • GRASSLANDS • AGRICULTURAL FIELDS • RIVERS, LAKES • BUILDINGS, PARKING LOTS

LAND USE/LAND COVER CHANGES

The Urban Hydrologic Cycle

WATER POLLUTION SOURCES POINT SOURCE POLLUTION NONPOINT SOURCE POLLUTION

Environmental Health Perspective, National Institute of Health

POINT SOURCE POLLUTION

• Comes from a specific source, like a pipe

• Factories, industry, municipal treatment plants

• Can be monitored and controlled by a permit system (NPDES)

NONPOINT SOURCE POLLUTION • Nonpoint Source (NPS)

Pollution is pollution associated with stormwater or runoff

• NPS occurs when runoff collects pollutants on its way to a collection system or water body

• NPS pollution cannot be traced to a direct discharge point such as a wastewater treatment facility

NPS = “People Pollution”

litter fertilizers

animal waste grass clippings septic systems

oil & grease from cars household cleaning products

sewage & cleaners from boats

These pollutants build up on the land then wash off

IMPACT OF NPS • Fish and wildlife • Recreational water

activities • Commercial fishing • Tourism • Drinking water quality

What is infrastructure? • Infrastructure includes

the basic structures and organizations needed to operate our cities: – roads – water supply – sewers – electrical grids – telecommunications,

Gray Infrastructure

• Roads

• Curbs & Gutters

• Catch Basins

• Sewer Pipes

• Retention & Detention Ponds

• Treatment Plants

Infrastructure

Green infrastructure is an approach to wet weather management that is cost-effective, sustainable, and environmentally friendly. Green Infrastructure management approaches and technologies infiltrate, evapotranspire, capture and reuse stormwater to maintain or restore natural hydrologies.

USEPA. 2009. Green Infrastructure Manual.

Rain Garden in Holmdel, NJ Native NJ Purple Coneflower Pervious Pavers

Green Infrastructure is ... …an approach to stormwater management that is cost-effective, sustainable, and environmentally friendly. Green Infrastructure projects:

• capture, • filter, • absorb, and • reuse

stormwater to maintain or mimic natural systems and treat runoff as a resource.

Green Infrastructure includes: Green Roofs Rainwater Harvesting Tree Filter/Planter Boxes Rain Gardens/Bioretention Systems Permeable Pavements Vegetated Swales or Bioswales Natural Retention Basins Trees & Urban Forestry Green Streets

How can we minimize the impact of stormwater runoff in our community?

It is all about controlling runoff from impervious

surfaces

The Hydrologic Cycle

We must deal with impacts from impervious cover

Are there impervious surfaces that you can eliminate?

Are there impervious surfaces that you can harvest rainwater for reuse?

If we can't eliminate it, can we reduce it?

If we can't eliminate or reduce it, can we disconnect it?

Are there conveyance systems that can be converted to bioswales?

Eliminate it!

Reduce It!

Disconnect It!

Runoff Direction

1 acre directly connected

impervious cover

2 acres pervious cover

Total drainage area = 3 acres

For 1.25 inch storm, 3,811 cubic feet of runoff = 28,500 gallons

Stormwater Inlet

Disconnect your downspout by installing a

Disconnection with Rain Water Harvesting

Impervious area is now “disconnected” from flowing directly into the storm sewer system

So Many Barrels to Choose From…

Or Larger Rainwater Harvesting Systems…

Rooftop runoff is now “disconnected” from flowing directly into the storm sewer system

Disconnection with Rain Gardens

Lots of Rain Gardens

Disconnect with a Tree Filter Box

What you can do…

Can your community benefit…

1. Does your community suffer from localized flooding?

2. Does your community have combined sewers?

3. Does your community pay too much for treating wastewater because of inflow and infiltration (I&I) problems?

4. Is your community committed to protecting the health of its residents?

Next Steps

• Discuss green infrastructure with your community leaders

• Identify most critical issues in your community

• Contact Rutgers Cooperative Extension Water Resources Program for a free consultation
