Evaluating Green Infrastructure: A Combined Sewer Overflow Control Alternative for Long Term Control Plans

The intent of this document, Evaluating Green Infrastructure: A Combined Sewer Overflow Control Alternative for Long Term Control Plans, is to provide guidance to Combined Sewer Overflow (CSO) permittees within the State of New Jersey to evaluate green infrastructure (GI) as part of their Long Term Control Plans (LTCPs).

LTCP implementation will be a long and expensive process. Many of the alternatives that will ultimately be implemented to address CSOs will be built on publicly owned land, the cost of which will be borne primarily by the rate payer. GI, however, can and should be implemented both on publicly and privately owned land, allowing the cost of GI to be shared by both the rate payers and private developers.

This guidance is not intended to be the sole resource for evaluating this alternative. This guidance provides case studies, links, and resources to assist
a CSO permittee with including GI as part of its CSO Long Term Control Plan.

Water Needs through 2040 for New Jersey Public Community Water Supply Systems

The New Jersey Department of Environmental Protection (NJDEP) contracted with Rutgers-The State University of New Jersey  to estimate water demands in New Jersey for each Public Community Water Supply system to the year 2040. The project results will support future water supply planning by NJDEP, including the Statewide Water Supply Plan. This project made several important advances regarding our understanding of water supply demands and demand forecasting.

This report provides a detailed technical discussion of the methodology, data collection, data analyses, model development and assumptions, and results for the project. It is not written or intended for general public use.

 

 

Asset Management Definitions Guidebook

The Asset Management Definitions Guidebook defines terms commonly used in water utility Asset Management practice. American Water Works Association’s Asset Management Committee developed it to help improve learning, consistency, and communication in the water industry. The Committee encourages professionals throughout the industry to use the guidebook, and expects the terminology in products that the Committee sponsors (e.g., publications and presentations) to be consistent with it.

As Asset Management practice in the water industry matures, its terminology is likely to change. Thus, the Committee plans to revise this guidance periodically to reflect changes, and invites people that use the document to send the Committee comments on how it can be improved.

Holistically Analyzing the Benefits of Green Infrastructure

This document is intended for smaller local governments with stormwater programs that are responsible for regulatory compliance with municipal separate storm sewer system obligations. It outlines an approach to holistically evaluate the benefits of implementing green infrastructure. The guidance places emphasis on first understanding the goal and scope for assessing benefits. It uses the goal and scope to step the user through: (1) differentiating between direct benefits and co-benefits of GI, and (2) understanding when and how these benefits need to be characterized, quantified or monetized.

The report is organized into three sections with attachments.

  1. The first section introduces the concept of green infrastructure and describes some of the most common GI practices.
  2. The second section discusses the range of benefits and co-benefits often attributed to GI.
  3. The third section outlines an approach to assessing the benefits.
  4. Finally,the attachments provide case studies that illustrate how this guidance can be used.

Joint Legislative Task Force on Drinking Water Infrastructure’s Final Report

The Joint Legislative Task Force on Drinking Water Infrastructure convened on Jan. 8 and voted unanimously to adopt the findings and recommendations in its report.

In response to concerns over the condition of the State’s drinking water infrastructure, on Jun. 30, 2016 the Legislature passed Senate Concurrent Resolution No. 86 and Assembly Concurrent Resolution No. 161, establishing the Joint Legislative Task Force on Drinking Water Infrastructure. The task force was charged with studying and making recommendations concerning issues related to drinking water infrastructure in New Jersey, and identifying both short-term and long-term solutions to address the quality and condition of drinking water infrastructure in the State. Read the Joint Legislative Task Force on Drinking Water Infrastructure’s final report.

Pursuant to these resolutions, the task force held three public hearings at the State House Annex in Trenton, New Jersey on Nov. 30, 2016, Dec. 14, 2016, and Jan. 26, 2017. At the first two hearings, the task force took testimony from invited guests on the current condition of the State’s drinking water infrastructure, what improvements are necessary to ensure a safe and adequate drinking water supply, and potential funding mechanisms for those improvements. At the third hearing, the task force took testimony from invited guests and members of the public on the issue of lead in drinking water. Transcripts for these hearings, including written testimony submitted by witnesses, are available on the Legislature’s website.

During its deliberations, the task force took testimony from a wide variety of government agencies, stakeholders, and experts in the field of water infrastructure, as well as members of the public. Over two dozen witnesses testified before the task force, including representatives from the New Jersey Department of Environmental Protection (DEP), the New Jersey  Environmental Infrastructure Trust (NJEIT), the New Jersey Department of Education (DOE), and the New Jersey Board of Public Utilities (BPU); investor-owned utilities, municipal utilities, and utilities authorities; nonprofit scientific and educational organizations; environmental advocacy groups; and the academic community. The input the task force received from witnesses serves as the basis for the findings and recommendations in this report.
