Laredo Utilities Advance Water Resiliency Initiatives in Alignment with Sustainable Development Goals

On November 13, utilities staff for the City of Laredo presented a multi-pronged strategy to enhance water supply resiliency. The initiatives directly support several United Nations Sustainable Development Goals (SDGs), primarily focusing on ensuring access to clean water and building sustainable urban infrastructure.

Strategic Initiatives for Water Security and Sustainable Infrastructure (SDG 6 & SDG 11)

A series of projects are underway to diversify water sources and fortify infrastructure, contributing to SDG 6 (Clean Water and Sanitation) and SDG 11 (Sustainable Cities and Communities).

• Wastewater Reuse: The city is evaluating the reuse of its 23,000,000 gallons of high-quality treated wastewater per day. This circular economy approach supports SDG 6.3 by improving water quality and increasing recycling and safe reuse, providing a critical emergency backup supply.
• Infrastructure Interconnection: A partnership with the U.S. Army Corps of Engineers (SDG 17) will fund a $26,000,000 project to interconnect the Altaico and Jefferson water treatment plants. This enhances operational resilience, ensuring continuous water flow and directly addressing SDG 11.5 by making the city’s water infrastructure more resilient to disruptions.
• Supply Diversification Study: In a public-private partnership (SDG 17), the city is studying the feasibility of blending groundwater with Rio Grande water. This effort to diversify the water portfolio is critical for achieving SDG 6.4, which aims to ensure sustainable withdrawals and supply of freshwater to address water scarcity.

Environmental and Transboundary Water Management (SDG 6, SDG 14, SDG 15)

The city’s planning incorporates environmental stewardship and recognizes the complexities of shared water resources.

• Ecological Impact Assessment: The potential use of Lake Casablanca as an emergency water source is under consideration. This process includes addressing environmental concerns such as dredging impacts, turbidity, and fish habitat, aligning with the principles of SDG 14 (Life Below Water) and SDG 15 (Life on Land) by protecting freshwater ecosystems. Engagement with state regulators is required as the lake is within a Texas state park.
• Transboundary Cooperation: Officials acknowledged the international dynamics of the Rio Grande basin. Managing agricultural water demands between the U.S. and Mexico highlights the need for robust transboundary cooperation, a key target of SDG 6.5 (Integrated Water Resources Management).

Governance and Forward Plan

A dedicated working group, led by the assistant city manager and city engineer, is overseeing the supply diversification efforts. The next steps are clearly defined to ensure progress.

1. Advance the groundwater blending study with the private partner.
2. Continue consultations with state regulators regarding the Lake Casablanca options and associated environmental permitting.
3. Proceed with planning for the U.S. Army Corps of Engineers-supported plant interconnection project.
4. Provide regular progress reports from the working group to the city council and the advisory committee.

Analysis of Sustainable Development Goals in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

1. SDG 6: Clean Water and Sanitation
   • The core of the article focuses on ensuring a resilient and sustainable water supply for Laredo, Texas. It discusses initiatives like treated-wastewater reuse, blending groundwater with river water, and protecting emergency water sources, all of which are central to SDG 6.
2. SDG 9: Industry, Innovation, and Infrastructure
   • The article explicitly mentions a significant infrastructure project: the “$26,000,000 project to interconnect the Altaico and Jefferson plants.” This initiative aims to build resilient infrastructure to guarantee continuous water service, directly aligning with the goals of SDG 9.
3. SDG 11: Sustainable Cities and Communities
   • The efforts described are aimed at making the city’s water system resilient to potential disruptions, such as the Rio Grande becoming “temporarily unusable.” This focus on building resilience against water-related shocks and ensuring the sustainability of urban services is a key component of SDG 11.
4. SDG 14: Life Below Water
   • When discussing Lake Casablanca as a potential emergency source, committee members raised “environmental concerns, including dredging impacts, turbidity and fish habitat.” This consideration for the health of an aquatic ecosystem and its inhabitants connects the discussion to the principles of SDG 14.
5. SDG 17: Partnerships for the Goals
   • The article highlights multiple collaborations to achieve water security. These include an agreement with the “U.S. Army Corps of Engineers,” a study with a “private partner (referred to in the meeting as Legacy),” and necessary engagement with “state-level regulators.” This multi-stakeholder approach is the essence of SDG 17.

2. What specific targets under those SDGs can be identified based on the article’s content?

1. Under SDG 6 (Clean Water and Sanitation):
   • Target 6.3: By 2030, improve water quality by… substantially increasing recycling and safe reuse globally. The plan to evaluate storing or blending “23,000,000 gallons of treated wastewater of excellent quality” directly addresses this target.
   • Target 6.4: By 2030, substantially increase water-use efficiency… and ensure sustainable withdrawals and supply of freshwater to address water scarcity. The entire strategy of diversifying water sources (groundwater, treated wastewater, interconnected plants) is aimed at ensuring a sustainable supply and reducing stress on a single source, the Rio Grande.
   • Target 6.5: By 2030, implement integrated water resources management at all levels, including through transboundary cooperation as appropriate. The mention of “international dynamics of sharing water along the Rio Grande” between the U.S. and Mexico highlights the need for and challenges of transboundary water management.
2. Under SDG 9 (Industry, Innovation, and Infrastructure):
   • Target 9.1: Develop quality, reliable, sustainable and resilient infrastructure… to support economic development and human well-being. The project to “interconnect the Altaico and Jefferson plants so one plant can sustain flow if the other goes offline” is a direct implementation of building resilient infrastructure.
3. Under SDG 11 (Sustainable Cities and Communities):
   • Target 11.5: By 2030, significantly reduce… the number of people affected… by disasters, including water-related disasters. The initiatives are proactive measures to prevent a water supply crisis if the primary source is compromised, thereby protecting the population from a water-related disaster.
4. Under SDG 14 (Life Below Water):
   • Target 14.2: By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts. Although Lake Casablanca is a freshwater body, the principle of protecting aquatic ecosystems applies. The concerns raised about “dredging impacts, turbidity and fish habitat” reflect an effort to manage a water resource while avoiding adverse environmental impacts.
5. Under SDG 17 (Partnerships for the Goals):
   • Target 17.17: Encourage and promote effective public, public-private and civil society partnerships. The article provides clear examples of such partnerships: a public-public partnership with the U.S. Army Corps of Engineers, a public-private partnership with “Legacy” for a blending study, and public-regulatory engagement with state authorities.

3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?

1. For Target 6.3 (Wastewater Treatment and Reuse):
   • A quantitative indicator is explicitly mentioned: the volume of treated wastewater available for reuse, which is “23,000,000 gallons.” A qualitative indicator is its “excellent quality.” This relates to Indicator 6.3.1 (Proportion of domestic and industrial wastewater flows safely treated).
2. For Target 9.1 (Resilient Infrastructure):
   • A financial indicator is provided: the investment in the interconnection project, which is “roughly $26,000,000.” The completion of the project itself would be a physical indicator of progress.
3. For Target 6.5 (Transboundary Cooperation):
   • The article implies a qualitative indicator: the status of cooperation and management of shared water resources. The mention of “international dynamics” and complications from “agricultural water demand” suggests that the level and effectiveness of cooperation is a key metric, relating to Indicator 6.5.2 (Proportion of transboundary basin area with an operational arrangement for water cooperation).
4. For Target 17.17 (Partnerships):
   • An indicator is the number and type of multi-stakeholder partnerships established. The article identifies three distinct partnerships: with the U.S. Army Corps of Engineers, a private partner (Legacy), and state regulators. The signing of agreements, such as the “study agreement with a private partner” and the agreement with the Corps, serves as a concrete indicator of progress.
