Runoff Ramblings
Water Supply, Wastewater & Stormwater: Are These Cousins Kissing or Feuding?

by David Hirschman, with contributions from Bill Stack

The following sad story was recounted recently by a kid on the playground:
"I am frustrated.  My name is Stormwater.  I have two cousins, Water Supply and Wastewater, and they don't play with me anymore.  We have the same grandparents (named Rain and Snow), but Water Supply and Wastewater are older and more sophisticated.  I just want them to play with me."
I feel Stormwater's pain.  Earlier in my career, I held a joint position between a water and wastewater utility and a county government.  The position focused on watershed management for a drinking water reservoir, recognizing that the quality of the product (clean drinking water) had as much to do with the watershed as it did with the treatment process.  The program integrated the utility's concern with water supply management with the county's responsibilities for land use planning, stormwater management, and development review. 
The key word here is integration.  These days, we are quick to evoke terms such as sustainability and integrated resource management, but it seems harder to actually accomplish the integration needed to achieve those lofty goals.  We can't even agree on spelling conventions, such as whether the "water" part of the terms "surface water," "groundwater," "stormwater," and "wastewater" should be its own word.  Why?
Certainly, part of the issue has to do with the regulatory context that puts water supply, wastewater, and stormwater into their respective programmatic silos.  The structure of local government can be another issue, with drinking water and wastewater generally handled by utilities and stormwater being housed in an engineering or planning department (not withstanding a new generation of integrated utilities discussed below).
Figure 1. The Regulatory & Programmatic Silos for Water Management
As my friend and former CWP colleague, Mike Novotney, points out, we tend to use different metrics to evaluate and manage the three systems, as described in Table 1.  These metrics are regulation and project-centric, and are not always relevant at the watershed or community scale.  Mike proposes a "water portfolio" concept to integrate water sources and needs at a watershed scale (see Novotney, 2010).
Table 1. Metrics for Gauging "Success" for the Three Water Management Sectors

Water Supply
·      Meet safe yield demand
·      Meet Safe Drinking Water Act standards
·      Meet minimum instream flow requirement below reservoirs

·      Provide treatment capacity
·      Comply with NPDES discharge permit

·      Match post-development to pre-development discharge
·      Treat the water quality volume
·      Comply with MS4 permit
Granted, each of the three regulatory and programmatic systems has accomplished tremendous things over the course of several decades.  But, the question must also be asked, what types of integration, efficiency, and creative management have been thwarted by the silo approach?  Perhaps more importantly, are we meeting human needs and protecting and preserving ecosystem services in the best way possible? What would be possible if the metrics for achieving success were integrated across the three sectors, and also integrated at the watershed scale?
Much has been written about "Integrated Water Resources Management" and "Total Water Management" (a slightly different topic), and my intention is not to review all of the theory and practice behind these topics.  Many organizations, such as the American Water Works Association and the Water Environment Federation, not to mention many academics, have written on the topic.
Suffice it to say, there are some promising trends that portend enhanced levels of integration. Among them:
Combined sewer systems (CSOs) across the country are starting to look at green infrastructure approaches for keeping more stormwater out of the combined system.  The common denominator for these efforts is volume, with efforts focusing on using the landscape and other BMPs to achieve a more natural "separation."  For examples, see Philadelphia, Cleveland Metro Sewer District, Cincinnati, Portland, Minneapolis, and many others (sorry if I left yours out).
Many municipalities are adopting stormwater utilities and housing these within their existing water and wastewater utility departments.  In some cases, the water and wastewater managers are looking at stormwater as a new and exciting challenge; others see it as a gawky and obnoxious teenager that has come to spend the summer.  In either case, as time goes by, these unified utilities will achieve heretofore unrealized levels of integration on financial and resource management levels.
A growing number of development projects are exploring rainwater harvesting, not just as a source of water for irrigation, vehicle washing, or toilet flushing, but as a way to manage stormwater runoff.  Increasingly, new stormwater ordinances and design manuals are incorporating particular standards for rainwater harvesting (for an example, see the Virginia Stormwater BMP Clearinghouse). More formalized integration exists in some states, such as Maryland, which, in 2006, adopted state legislation known as the "Water Resources Element."  This legislation requires that local jurisdictions modify their comprehensive plans to assure that existing and future development can be supported by water and wastewater resources and to provide goals, policies and strategies for conservation, pollution reduction, and prevention of water quality degradation. Essentially, the plans have to address whether there is enough water and wastewater capacity to support future growth and how much development the watershed(s) can accommodate before nutrient load thresholds (e.g., TMDLs) are exceeded.  For more information, see the Maryland Department of Planning's publication The Water Resources Element (document #26 under Models and Guidelines).  Some localities, such as Cary, N.C., have developed locally-driven integrated water resources management plans (Novotney, 2010; see the Integrated Water Resources Management Plan on the Town of Cary's website).

There are other drivers for water resources integration.  Planning for climate change is fueling a new vigor for looking more holistically at water, infrastructure, ecosystem services, and public safety.  These are not just academic concerns.  Water is limited, and our communities live within the constraints and opportunities of the hydrologic cycle.  Let's start planning and managing the system as if that really matters.  The playground is large enough for all the water cousins to play nicely together (whether they actually do is not my concern).

Center Sewage Sleuths Help to Reduce Pollution in Baltimore Streams

B'More IDDE 1Illicit Discharge Detection and Elimination (IDDE) is a requirement of MS4 permits; however, it can also be an efficient and cost effective best management practice (BMP) that communities with non-stormwater discharge (NSD) problems can utilize to meet water quality goals and TMDLs.  In addition, it has the potential to be used as tool within the framework of an integrated water management strategy for wastewater, drinking water and stormwater.  The benefits of an effective IDDE program to local jurisdictions stretch beyond the MS4 permit and into the realm of total watershed management.  The implementation of IDDE field surveys can help to isolate problems at the subwatershed and reach level and, eventually, to the source of significant pollution problems. 
The Center for Watershed Protection (the Center) conducted illicit discharge outfall screening in two subwatersheds in Baltimore, Western Run and Moores Run, as well as a portion of the Jones Falls mainstem with the following goals:
  • Inventory and collect data from all dry weather flowing outfalls
  • Work with City to eliminate NSDs
  • Calculate NSD loadings from nitrogen, phosphorus, bacteria and pollutant volume
  • Document findings in a technical memo
  • Communicate project results
The Center, Baltimore City, Baltimore County and watershed group staff, with the help of volunteers, walked over 18 miles of stream in May - July 2010 to assess 81 outfalls within the study area.  Field crews determined the illicit discharge potential of individual outfalls from physical indicators and an ammonia test and then took three grab samples that were analyzed for additional parameters including total nitrogen, total phosphorus, fluoride, anionic surfactants (detergents), potassium, E. coli and total coliforms.  This suite of parameters can help to determine a source of pollution as either wastewater, washwater, tap or irrigation water, or groundwater.
Results of the study point to a significant amount of pollution from NSDs in these watersheds.  80% of all outfalls surveyed for dry weather flow exceeded one or more thresholds for the parameters identified above.  Sewage contamination from accidental cross-connections, sewer line failures, choked sanitary stacks and so on contribute a significant amount of nutrient and bacteria load to receiving water bodies.  The nutrient load from confirmed sewage discharges found in one subwatershed of this study represent 50% of total in-stream nitrogen load, 8% of the total in-stream phosphorus load and only 1% of the total stream discharge.  In addition, it was determined that up to 550 million gallons of treated drinking water is lost through leakage in just 11 outfalls surveyed on the Jones Falls mainstem.  Approximately 50% of all outfalls with dry weather flow exceeded the EPA water quality standard for water contact recreation (235 CFU/100 ml). 
Source tracking efforts by City and County staff led to the elimination of some of the problems that were found, including several of the major sewage sources, and the remaining are being addressed or on schedule to be re-tested.  If left untreated, the illicit discharges detected through this study could contribute 12,500-37,500 lb/year of total nitrogen and 500-1500 lb/yr of total phosphorus (a range of 50-150% is reported as these discharge are often of a diurnal or intermittent nature).  The elimination of these pollution sources by tracking them down and fixing them has resulted in a reduction of 7,300-22,000 lb/year of total nitrogen and 400-1200 lb/yr of total phosphorus.  The average E. coli count for the fixed problems was well above safe levels, with an average >45,000 CFU/100 ml detected.  In addition, a major water main break was found and is scheduled for repair.  The break represents a loss of over 300 MG/yr of treated drinking water as well as a significant nitrogen load.
Overall findings of the project include the following:
  • Illicit discharge surveys can help communities to determine the impact to receiving water quality by NSDs during baseflow conditions
  • IDDE can be used as a best management practice to meet nutrient and bacteria water quality standards as well as TMDLs.
  • The MS4 and Sanitary Sewer program must collaborate on the prevention and efficient/effective fix of illicit discharge problems.
  • Minor outfalls, those less than 36" in diameter, contribute heavily to pollution and should be monitored alongside major outfalls.In this study, 45% of all flows exceeding the established criteria for dry weather flow came from small pipes and all small pipes exceeded one or more thresholds.
  • Leakage of treated drinking water is significant; 11 outfalls on the Jones Falls mainstem represent a potential loss of up to 550 million gallons per year of treated drinking water.
  • E. coli levels were pervasive throughout the study area, including in those outfalls determined to be "clean," that is, not exceeding any of the illicit discharge criteria.
  • Watershed groups and municipalities can collaborate to implement an effective IDDE program and citizen water quality monitoring groups can enhance existing program by using some of these strategies.
  • IDDE is one potential tool for integrated water management of drinking water, stormwater and wastewater.

The Eight Tools are Going Coastal!

Project Background
In 1998, the Center for Watershed Protection (the Center) created a comprehensive local framework for watershed planning known as the Eight Tools of Watershed Protection. The "Eight Tools" address land development stages from initial land zoning to site plan development and review through construction and occupancy. Since then, the Center has applied the "Eight Tools" in numerous watersheds across the country and has continuously tested, refined, and updated it. Although the "Eight Tools" framework has been used throughout the United States, many of its specific recommendations are derived from research in the Piedmont province, and it was unclear how well these recommendations would apply in regions with different physical characteristics and development patterns, such as the Atlantic coastal plain province.  The Atlantic coastal plain borders the Atlantic Ocean and Gulf of Mexico from Cape Cod down to the Mexican border. It stretches 2,200 miles in length and includes portions of 21 states (see map below).  To address this gap, the Center conducted a two-year research effort focused on developing improved watershed management tools for the coastal plain.
Coastal Plain Map
Research Methods and Key Findings

Major research tasks for this project included a watershed management needs survey of coastal plain communities and a review of literature on the impacts of urbanization on coastal plain water resources.
Coastal Needs Survey
The Coastal Needs Survey, distributed in the fall of 2008, was designed to understand how resources are currently managed in the coastal plain, and to quantify the needs of coastal plain watershed managers. Representatives from 73 coastal plain communities completed the survey.  And while survey results revealed that the majority of communities implement the eight tools of watershed protection to some extent, the tools are somewhat limited by ineffective application or incomplete implementation.   Although the communities have, for the most part, sufficient technological capacity, staffing limitations and political will hamper implementation of watershed protection practices.
Although the coastal plain has certain unique physical characteristics, many of the key challenges identified by watershed managers, such as lack of funding and limited staff resources, are not unique to the coastal plain.  The survey results suggest that communities put most of their resources towards satisfying regulatory mandates, leaving few, if any, resources to 'add' new initiatives, such as watershed planning. Greater consolidation or coordination between land use planning, watershed management, and stormwater management programs may help these communities realize efficiencies that allow them to pursue watershed protection, while simultaneously continuing to meet federal mandates.
Literature Review
In order to clarify the relationship between land use factors and coastal watershed health and translate these findings into practical management tools for the coast, we reviewed forty-six research studies that evaluate the influence of land use change on the quality of aquatic resources in the coastal plain.  Findings from these studies suggest that indicators that measure the intensity of development (e.g., impervious cover or total urban land) in the study watershed, or the location of developed land in relation to the sampling station (e.g., urban land within a specific distance from the stream corridor) are the best predictors of aquatic health. Several other non-urban indicators, such as septic system density, also showed some potential to predict aquatic health, but additional research is needed to draw firm conclusions. 
One of the original intents of the project was to develop a "coastal impervious cover model," which would relate watershed impervious cover in the coastal plain to aquatic health in these watersheds.  Taken as a whole, the research did not point to a new model, and in fact suggest that the impacts of land development in the coastal plain are similar to those in the Piedmont.  One significant difference, however, appears to be that the location of development may be more important in the coastal plain than in the Piedmont.  The flat topography and extensive wetland network found in the coastal plain offer one explanation for this finding.  While riparian buffers play an important role in the Piedmont, the relatively steep slopes of that region often create a conditions where stormwater runoff can "short circuit" the buffer, either by direct piping, or through concentrated flow conditions.  In the coastal plain, on the other hand, the extensive flat areas and wetlands adjacent to streams and other waterways create a more effective buffering and filtering mechanism to mitigate the impact of development. 
Project Products
Using the combined results of the survey and literature review along with input from researchers and managers working in the region, we developed an adapted "Eight Tools" framework for the coastal plain.  In many cases the results are applicable beyond the coastal plain to other coastal regions or to regions with similar characteristics and challenges.  A special issue of the Center's publication Watershed Protection Techniques, focused on coastal plain watershed management, presents the "Coastal Eight Tools" framework. The introductory articles in this issue provide the context for coastal plain watershed management while the remaining articles discuss the "Coastal Eight Tools" and provide examples applications in coastal plain watersheds.
The Coastal Plain Watershed Information Center, another product of this project, acts as a repository for the coastal plain information developed through this project and gleaned from others' relevant work.  The site currently includes the special coastal issue of Watershed Protection Techniques, a selection of the "best of the best" coastal watershed resources, case studies, and outreach materials for coastal managers. We will continue to add to this site as we work on a related project to address barriers to implementation of low impact development in the coastal plain.  For more information about his project, contact Karen Cappiella.
Funding and support for this project was provided by CICEET, the Cooperative Institute for Coastal and Estuarine Environmental Technology. A partnership of the National Oceanic and Atmospheric Administration and the University of New Hampshire, CICEET develops tools for clean water and healthy coasts nationwide.
Center Releases New Watershed Curriculum Module
The Center is always looking for ways to learn about the latest research and technologies to advance the fields of watershed and stormwater management to protect and restore our watersheds. We recently had the opportunity to go to the source of learning and work with three universities to develop watershed-based curriculum into existing courses. Universities play a critical role in building watershed capacity by introducing students to the watershed profession, training them on the latest watershed methods, and conducting research to improve watershed understanding and practice.
We surveyed universities throughout the United States to identify their watershed curriculum needs and initiate the development of the materials. We were pleased to find that watershed science, as well as stormwater management, is being taught in a diverse range of departments to include geography, biology, ecology, engineering, landscape architecture, as well as interdisciplinary natural science-political science programs.
An EPA Targeted Watershed Grant provided funding to work with three university partners who were selected based on their interest identified in the survey and location in different regions throughout the United States. A secondary goal was to work with a program where the subject of watersheds was not typically a part of the traditional course curriculum but would advance the student's understanding of their field of study. Our appreciation is extended to our partners who were willing to work with us to develop these new materials and test them in their classes earlier this year.  The partners were: Professors William Jones from Indiana University, School of Public and Environmental Affairs, Christina Cianfrani from Hampshire College, School of Natural Science and Ken Yocum from University of Washington, Department of Landscape Architecture.
The materials developed as a result of this project are integrated into the Center's first Watershed Curriculum Module (WCM), available at The WCM offers three units that are designed to enhance a student's critical thinking skills by applying knowledge learned in the classroom to 'real world' examples, to define and test hypotheses, and integrate multiple sources of information to analyze data and make recommendations for future management decisions. 
Unit 1: Watershed Assessment
The Watershed Assessment unit provides instructional versions of three popular field assessments to identify pollutant sources in neighborhoods, commercial & institutional hotspots, and evaluate the condition of stream reaches. The material is adapted from the Center for Watershed Protection's eleven manual Urban Subwatershed Restoration Manual series. This unit provides an opportunity for students to develop field skills and translate their findings to solutions to better manage watersheds and stormwater.
Also, check out the stormwater retrofit training videos on YouTube that were also developed as a part of this project. The videos are four and a half minutes to eight minutes in viewing time. There are three videos that introduce the concept of stormwater retrofits and how to conduct an assessment in the field. The retrofit videos can be accessed at the links below:
Unit 2: Watersheds & Growth: Land Use Planning as a Best Management Practice 
The "Watersheds & Growth" unit is a creative, hands-on group exercise for students to explore the impacts of development on watershed health and how land use planning decisions about the location and density of development may reduce these impacts. Students use Lego© pieces that represent development to decide where to place growth on a watershed map.  A supplemental photo gallery is provided to complement this unit to illustrate various site design practices and techniques known as "better site design" or "environmental site design" practices.  These practices work together to reduce the amount of impervious cover, protect natural resources and provide effective stormwater management on development sites. 
Unit 3: Watershed Treatment Model

An instructional version of the Center's updated Watershed Treatment Model is provided with an example case study and scenarios to familiarize students with an empirical model to evaluate the impact of urban development  and identify treatment options to reach a targeted pollutant load and runoff reductions. A copy of the WTM, an instructional guide and a case study is provided for students to learn more about the WTM and how to use it.

New USGS podcast about the effects of urbanization on stream ecosystems
A new U.S. Geological Survey video podcast describes the adverse affects of urban impervious cover and stormwater on stream health.  When the area of driveways, parking lots, streets and other impervious cover reaches 10 percent of a watershed area, many types of pollution sensitive aquatic insects decline by as much as one third, compared to streams in undeveloped forested watersheds.  The rapid rise and fall of stream flow can damage the living spaces of fish and aquatic insects. Stormwater from urban development can also contain fertilizers and insecticides used along roads and on lawns, parks and golf courses. Podcast participants conclude that no 'safe zone' of impervious cover exists, meaning that even the early stages of development can negatively affect aquatic life in urban streams.

"Stream protection and management is a top priority of state and local officials, and these findings remind us of the unintended consequences that development can have on our aquatic resources," said Tom Schueler, Chesapeake Stormwater Network coordinator and podcast participant.

USGS studies examined the effects of urbanization on algae, aquatic insects, fish, habitat and chemistry in urban streams in nine metropolitan areas across the country: Boston, Mass.; Raleigh, N.C.; Atlanta, Ga.; Birmingham, Ala.; Milwaukee-Green Bay, Wis.; Denver, Colo.; Dallas-Fort Worth, Texas; Salt Lake City, Utah; and Portland, Ore.

Cause of dead zone in Gulf: Tile drainage directly related to nitrate loss
A recent study by University of Illinois and Cornell University researchers shows that the most heavily tile-drained areas of North America are also the largest contributing source of nitrate to the Gulf of Mexico, leading to seasonal hypoxia. Read more about this study here

Landscape targeting matrix helps prioritize buffer restoration sites with high nutrient reduction potential
The Chesapeake Bay Forestry Workgroup recently agreed to support the use of a landscape targeting matrix developed for riparian forest buffer effectiveness.  Local jurisdictions with GIS capabilities can use the targeting process outlined in a Forestry Work Group guidance document to determine priority locations for riparian forest buffer restoration, enhancement, and conservation.  This process prioritizes forest buffer restoration sites with high nutrient reduction potential.  The process works by assigning weights to various attributes and map layers associated with buffer function such as depth to ground water, slope, land use and nutrient loading.  The resulting map provides information on the locations where buffer establishment will provide the most benefit.  The tool can help ease the pressures to meet TMDL and Milestone goals by maximizing efforts to implement effective best management practices.  Additionally, the amount of time and fuel spent searching the jurisdiction to find sites for riparian forest buffer restoration and conservation opportunities should be significantly reduced.  To learn more about the tool contact Judy Okay or Sally Claggett at the Chesapeake Bay Program at 410-267-5700.
