The buy local food movement has grown in recent years. But here is a more effective movement: drink local water. Yes, water infrastructure is the need of the hour to reduce water wastage and increase resources to harness it efficiently. Today we will delve into the transformative power of modern technology, showcasing its ability to revitalize aging urban water systems, ensure localized supply networks, and pave the way for sustainable water management in our rapidly evolving cities.

In Deep Water: How Today’s Technology Can Localize and Restore Urban Water Infrastructure

Municipalities centralized water systems and neglected water infrastructure. This leads to rationing, flooding, and sewage overflows. Water line bursts and pipe leaks are common in the US. To fix this, we should localize urban water systems and restore water infrastructure using current technologies.

Factors for sustainable local water systems

To save money and protect the environment, governments and utilities can follow these processes:

  • Prioritize reusing and recycling water.
  • They should also consider conservation policies, leak repairs, and water recycling before transporting water.
  • Instead of relying on dams or desalination plants, they could explore alternative cooling or fracking methods.
  • Real estate owners can also reuse stormwater and black-water onsite for irrigation and other non-potable needs.
  • Localizing the water system leads to better service and reliability at a lower cost.

Steps to take to localize an urban water system.

To localize an urban water system, it’s important to understand the watershed surrounding the city and be able to design and analyze new possibilities in that context. This includes gathering data on current conditions and evaluating different designs, as these groups have already done.

Restoring water infrastructure

In order to fix water infrastructure, it is necessary to attract long-term funding at reasonable rates. This can only be achieved if the government inspires confidence, ratepayers are willing to contribute, and private investors can expect a return on their investment.

Localized Water Infrastructure

To localize and restore urban water infrastructure the government introduced Localized Water Infrastructure. It refers to dispersed facilities that are located near or at the point where they are used. These facilities aim to improve water efficiency indoors and outdoors, promote onsite reuse, implement green infrastructure, and reduce lead exposure. LWI is often installed through consumer incentives, as they are not owned or controlled by the city or water utility.

LWI can decrease demand and create new local water sources. In 2019, cities and utilities in the EPA’s WaterSense program saved the same amount of water that all U.S. Households used in 6 months since 2006.

MMSD, a utility in Milwaukee, is focused on managing stormwater. They plan to capture 740 million gallons of stormwater per storm with Green Infrastructure by 2035, which is 220 gallons more than what their deep tunnels can capture.

Protecting and restoring source watersheds is considered a form of water infrastructure. Central Arkansas Water, for instance, pays private landowners with bond proceeds for conservation easements. This has resulted in the protection of nearly 3,000 acres of land in the source watershed, as of 2017.

Lead service lines pose a serious health risk, especially in under-resourced areas and communities of color. There are approximately 6.1 million lead service lines still in use nationwide. The federal government plans to invest $15 billion in replacing these lines over the next five years under the Bipartisan Infrastructure Law. While some cities are waiting for this funding, Madison, Wisconsin took action earlier by completing the first city-wide lead service line replacement program in 2011. This program has already saved them $2.5 million by eliminating the need for ongoing chemical treatment.

In addition to providing water services, LWI also offers social equity benefits. As LWI is present throughout the community, it guarantees a fair distribution of costs and advantages. Moreover, LWI installations can be prioritized for communities that are disproportionately affected by issues like combined sewer overflows, polluted urban run-off, contaminated drinking water, flooding, and drought. The investments made in LWI demonstrate that these distributed approaches are truly effective water infrastructure solutions. They fulfil the three essential functions required in urban areas and promote equity and affordability.

Urban Water Supply Automation

Automation is a comprehensive set of theories and methods that enable a system to function seamlessly and effortlessly. In the context of urban water supply, automation plays a vital role. A key aspect of automation lies in the feedback principle, where a sensor measures a specific variable, such as concentration. A computer then validates the measurement, followed by an algorithm that determines the necessary corrective actions. These actions are subsequently executed by mechanisms, such as pumps or valves, without any human intervention necessary.

Provide the goal to the controller when using automation. The main component of automation is a system that can represent any part or process in the water supply system, or even the entire system. It is important to have a true understanding of people at all levels when using automation technology to avoid misunderstandings and failures.

Automation can help in three main areas: uncertainty, feedback, and complexity. Managing disturbances is a key challenge. Future urban areas will need to integrate the management of the entire water cycle for sustainable operations. Automation is essential for making integration possible in complex systems.

Application of Smart City and Smart Water Management

Cities need to install water sensors in their water networks to manage water effectively. These sensors will measure flow rates and detect leakages. They will also monitor water quality by measuring pH, dissolved oxygen, and turbidity.

Installing smart water meters can enhance people’s intelligence by providing:

  • Real-time information about their water consumption
  • Users can effortlessly monitor their own water usage and compare it with others in their vicinity, stimulating a sense of competition and awareness.
  • Additionally, these meters will automatically transmit data on water consumption, streamlining billing procedures for a hassle-free experience.

Smart meters have the capability to not only notify customers about sudden surges in water usage, but also prompt the utility company to provide water conservation tips in the subsequent water bill, including guidance on detecting and addressing leaks.
