Data centers help Texas town solve water shortage problem

Despite debates over environmental consequences and public concerns, towns like Childress have found a way to cope with the chronic water shortage problem thanks to the boom in data centers across the United States.

The town in northwest Texas, which lacks its own water sources, relies on the Greenbelt reservoir located about 100 kilometers away and managed by state authorities. However, the water level in it is gradually dropping due to years of drought in the region, according to Childress mayor Cary Preston, speaking to Lusa agency.

Preston acknowledged that the drought is likely to last several more years, and the reservoir's water level is a serious concern. The state agency responsible for the lake's outflow is investing in water wells that will only become operational by the end of next year. Nevertheless, the construction of data centers in the area has provided the town with benefits it could not refuse, especially regarding water supply.

Within 10 kilometers of the city limits, the Texas company Lancium acquired over one hundred hectares where it is building and expanding a data center that will serve companies such as Meta. The construction has already transformed the landscape, and the scale of work and earthmoving attracts attention from heavy truck and machinery traffic. Huge power lines, powered by an extensive solar power plant, are being brought to the construction site.

Only in Texas are there over 300 operating data centers, with another two hundred planned for construction in the state. Their appearance raises anxiety and criticism among residents due to high energy and water consumption for cooling, as well as atmospheric, visual, and noise pollution. Issues surrounding data centers have become a central theme of the November 3rd midterm election campaign in the United States, particularly in Texas.

While Republican Senate candidate Ken Paxton advocates for their expansion, Democrat James Taralico shares the concerns and objections of the population worried about the impact of these facilities on quality of life and calls for restrictions.

Cary Preston, aware of the 'nightmare stories' of other Texas communities, is confident that Childress is 'lucky.' The local groundwater is brackish, and although it is used for server cooling, human consumption requires purification. Lancium 'offered' Childress and other small towns in the region the construction of a purification plant and an aqueduct through which four million liters of drinking water are planned to be supplied daily. This project represents investments worth tens of millions of dollars, which the city could not secure on its own, and Preston noted that the water could arrive in April of next year.

In one year, the construction of data centers has had a noticeable impact on the population, doubling it from approximately 5,500 people. This has led to a sharp rise in rent, as the city was unable to accommodate such a large number of people. Since 1985, Childress has seen no significant increase in housing stock, and owners have found a way to earn money by raising rents, a matter the local administration has no right to influence.

Landowners have invested in converting plots into trailer parking lots that house data center workers. Consumption in the city has sharply increased, boosting revenue from municipal consumption tax. Preston explained that these taxes help maintain infrastructure, keep streets in good condition, and support fire services.

In addition to water supply, taxes collected by the state of Texas from data centers will be directed to the county education system to implement projects for building new schools and improving existing ones.

Preston suggested that the town is 'lucky,' acknowledging that such significant population growth has overloaded existing infrastructure but has also stimulated the city's development.

Despite the population increase, foot traffic in Childress's historic downtown, established in 1887, remains rare. On Main Street, which resembles an open museum, traces of past life remain, such as an old cinema closed since the 80s, or the old newspaper Childress Index. The situation is changing at the intersection with Highway 287, which runs through Texas from the Gulf of Mexico to Oklahoma, where the roar of trucks is constant. At the other end of town, another noise and a familiar horn indicate the passage of a train carrying hundreds of containers on the old Burlington line, which served the American Midwest states from Colorado to Texas until the 1970s.

Preston, whose main job is related to an insurance brokerage founded by his grandfather, concludes: 'We are a small rural community. I think we are only seeing the tip of the iceberg of people coming to build and work in data centers. But the problems this has brought regarding coexistence with those who lived here before are the same as before. It's people complaining about a neighbor's dog barking at night, or loud music from another passing car.' He added that 'we will certainly have growing pains, but I think the star of Childress will shine again in Texas,' expressing hope.

Rainwater harvesting experience in Chennai may help Hyderabad solve water shortage problem

Rainwater harvesting experience in Chennai may help Hyderabad solve water shortage problem

In 1995, Professor Sekhar Raghavan noticed an unusual phenomenon: the tap water in Chennai had become brackish. This occurred against the backdrop of declining groundwater levels, causing seawater to seep into the city's underground freshwater reserves, making its use increasingly difficult.

The problem was not a lack of rainfall, as Chennai received a significant amount of rain. However, most of this water flowed into roads and drains into the sea instead of replenishing the groundwater beneath residents' homes.

This fact prompted Raghavan to ask himself: if rain falls over the city, why is so little of it conserved? His answer was to convey the idea of rainwater harvesting to the public. Armed with a bicycle and a simple message, he began visiting neighborhoods, going door-to-door to convince residents to collect rainwater and direct it back into the ground.

Nearly three decades later, his campaign offers a valuable lesson to another Indian city facing a water deficit—Hyderabad.

When it rains, but wells dry up

The city, home to about 1.5 million people, struggles with a severe shortage of drinking water. Causes include uneven regional distribution of water resources, competition between agricultural and industrial needs, and monsoon deficits.

According to data provided by the State Irrigation Department, more than 330 out of over 600 mandals in Telangana were classified as drought-affected, and only about 500 of the state's more than 6000 lakes contain water.

Pressure on water resources is evident in the city's growing reliance on tankers. Daily orders have risen to 6,000–8,000, prompting Ashok Reddy, Managing Director of the Hyderabad Waterworks and Sewerage Board, to instruct staff to bring in additional tanker operators and begin their registration.

In some parts of Secunderabad Cantonment and on the outskirts of Hyderabad, residents report receiving drinking water only once every three or four days. It is also reported that one of the city's main reservoirs has dropped to about 13% of its capacity.

However, the shortage is not only related to the amount of incoming water but also to how much the city can retain it. This is where the Chennai experience becomes relevant.

One bicycle, one neighborhood at a time

When Raghavan started his campaign in 1995, rainwater harvesting was not a common practice for most urban households. He aimed to change this situation by explaining how rainwater collected from roofs, driveways, and other surfaces could be filtered and directed into replenishment systems, allowing it to seep into the soil and restore underground aquifers.

Instead of letting rainwater run off into drains, households could capture it and help replenish the groundwater they depended on.

Nevertheless, convincing people proved harder than explaining the scientific principles. Raghavan cycled through neighborhoods, talking to residents and encouraging them to install collection systems. Many initially rejected the idea, but he continued to work with communities, demonstrating how it could be implemented.

Through the Rain Centre, which he headed, he also collaborated with teams of plumbers and well diggers to survey systems across the city and demonstrate rainwater harvesting on model houses.

How Chennai turned an idea into law

In October 2002, the Tamil Nadu government passed legislation making rainwater harvesting mandatory. In June 2003, a decree extended this requirement to all existing buildings across the state, including Chennai.

Property owners were required to install systems by October 11, 2003. Non-compliance could result in fines or disconnection of the municipal water supply.

A government announcement in November 2003 stated that 99.5% of Chennai residents had implemented rainwater harvesting in their homes and complexes.

However, installing a system and ensuring its functionality are two different processes. An inspection conducted by the Rain Centre in a residential area between October and November 2003 showed that about half of the residents had implemented rainwater harvesting inadequately.

Even among those who installed systems correctly, many focused only on collecting rainwater from roofs, ignoring another important source: rain falling on the rest of their property.

In housing complexes, this surface runoff could account for twice the volume collected from roofs. Although this water may not be suitable for direct domestic use, it can still be directed into the soil to replenish groundwater. As it moves through the soil, natural filtration helps remove pollutants.

The missing piece: what happens outside the roof? Raghavan's work also highlighted a broader gap in Chennai's approach. While households were responsible for collecting rainwater on their premises, public spaces represented another opportunity. Roads, parks, and playgrounds receive significant amounts of precipitation. Nevertheless, most of the water running off Chennai's storm drains is directed to the city's waterways and ultimately discharged into the Bay of Bengal.

Instead of letting all this runoff disappear, the Rain Centre advocated for directing appropriate urban runoff into replenishment systems. However, this requires careful planning. Road runoff carries solid waste, fine silt, and other pollutants that can clog collection systems. Therefore, systems must incorporate filtration, waste removal, and regular maintenance.

The city also needs adequate open spaces and properly designed replenishment systems to prevent water stagnation and flooding. In other words, rainwater harvesting is only one part of water management.

What the Chennai experience teaches Hyderabad

The results of Chennai's efforts became clearer after the return of rains. Tamil Nadu received below-average rainfall in 2003 and 2004, which made it difficult for residents to immediately observe the benefits. The following year brought heavier rains, which allowed for a clear demonstration of what could be achieved with functioning collection systems.

After the 2005 rains, the Rain Centre recorded an increase in groundwater levels by approximately 20 feet in the areas under its control, prompting the team to continue its work. For nearly 15 years, rainwater harvesting helped Chennai strengthen its groundwater reserves. However, the 2019 water crisis revealed limitations related to infrastructure that was no longer being maintained properly. Clogged filters, abandoned recharge pits, and poorly functioning systems weakened the effect of the initial initiative.

Today, Chennai is exploring additional approaches, including 'sponge parks' and underground rainwater harvesting systems, to improve its ability to retain precipitation. For Hyderabad, the lesson is not simply to copy Chennai's legislation or install collection systems on buildings. It is about creating a system where households, communities, and civic authorities share responsibility for rainwater harvesting, maintaining recharge systems, and protecting groundwater.

Raghavan's journey began with a brackish tap and a bicycle. It was followed by a city-wide dialogue that helped turn a lost resource into a priority of urban water resource management.

Three Indian cities implement various methods to combat road dust and improve air quality

Although a clean road does not guarantee clean air, three Indian cities are offering unique approaches to solving the problem of road dust. For instance, on November 5th, the Air Quality Index (AQI) in Delhi reached 370, classifying the capital as being in the very poor category. In the Jahangirpuri area, the index rose to 459, falling into the severe category.

As winter approaches in North India, it is customary to intensify street cleaning, spray water, and inspect construction sites. However, there is an issue with cleaning methods: a street may look immaculate, yet fine particles still rise into the air. Transport can then re-suspend this dust, exposing pedestrians, cyclists, and residents to pollution.

The question is not simply whether municipalities should clean more often, but whether they can remove dust in a way that prevents it from becoming airborne. Three Indian cities are demonstrating different solutions to this problem: Lucknow has expanded mechanized cleaning, Parwanoo has focused on repairing dust-generating surfaces, and Chandigarh is testing a method combining water washing with treatment and mechanical cleaning.

Lucknow goes beyond simple sweeping

In September 2026, Lucknow ranked first in the Swachh Vayu Sarvekshan among cities with a population over 1 million. Its 70th ward in Zone 4 also became the national leader among wards with a population exceeding 30 thousand. This recognition resulted from city-wide efforts to combat various sources of pollution, including road dust, transport emissions, and waste burning.

The Lucknow Municipal Corporation deployed 97 electric mechanized cleaning vehicles. These machines use rotating brushes to collect debris, and suction systems help capture finer material instead of just displacing it. Furthermore, the city paved approximately 559.85 km of roads, reducing the amount of open surfaces that can be disturbed by passing vehicles. Officials noted that the combination of mechanized cleaning and paving contributed to controlling re-suspended road dust.

The ward-level recognition is particularly important because air pollution is felt locally. A city might have an ambitious clean air plan, but residents experience its outcomes right on the street near their homes. The achievement of the 70th ward shows how actions to improve air quality can be assessed at the neighborhood level. Nevertheless, the award does not determine how much the pollution caused by individual measures in that ward has decreased. The task is to turn recognition into sustainable, measurable improvements in the air breathed by residents.

Parwanoo addresses the source of road dust generation

In Parwanoo, a town in Himachal Pradesh, officials started with a different question: what if the road itself is the source of the dust? A study conducted by IIT Kanpur covering an area of 8.5 sq. km in the city identified road dust as a significant source of air pollution. The municipal response was aimed at repairing surfaces and conditions that allowed dust to accumulate.

A 9 km stretch of road was upgraded using paving stones and interlocking blocks, replacing deteriorating surfaces. Drainage systems were improved to prevent erosion, and construction and demolition waste came under closer scrutiny. The city also created 0.27 acres of green buffer zone, intensified afforestation efforts, and restricted illegal dumping.

The results were measurable. The annual average concentration of PM10 in Parwanoo decreased from 66 micrograms per cubic meter in the 2017-18 period to 39 micrograms per cubic meter in the 2023-24 period, representing a reduction of approximately 41%. PM10 refers to particles with a diameter of 10 micrometers or less, and road dust can contain such particles that enter the respiratory system. This reduction cannot be attributed solely to paving; Parwanoo's efforts included a range of measures, and the city's experience demonstrates the value of eliminating dust at its source rather than relying solely on post-accumulation cleanup.

Chandigarh tests the effectiveness of washing

Chandigarh is approaching the problem through a pilot project. In September 2025, the Chandigarh Pollution Control Committee instructed officials to launch a dust control initiative along a dust-prone corridor. The plan combined road washing using treated water, mechanical sweeping, and roadside cleaning.

Roadsides are important because loose soil and litter along the edges can be repeatedly disturbed by vehicle traffic. Cleaning only the central lane might leave a significant dust source untouched. The committee planned to monitor PM10 levels during the pilot project and use the data to decide on potentially expanding the intervention city-wide. The project also fits into broader efforts to control construction and demolition waste. Authorities mandated institutions and agencies to suppress dust at storage sites, cover loose soil with vegetation, and use sprinklers or anti-smog installations where appropriate.

It is important to note that the Chandigarh project was announced as a pilot, not a proven city-wide success. Its value lies in testing whether the combined approach of road washing and mechanical cleaning, along with air quality monitoring, can establish their effectiveness.

What Delhi can learn

Air pollution in Delhi is caused not only by road dust. Transport emissions, industrial activity, construction, waste burning, agricultural fires, and winter weather conditions all contribute to episodes of poor air quality in the city. However, this does not make road dust control insignificant; it only underscores the importance of targeted measures.

Lucknow demonstrates the value of mechanized cleaning and ward-level action. Parwanoo shows why repairing damaged roads and controlling construction waste can prevent dust accumulation. Chandigarh is exploring whether treated water washing and roadside cleaning can improve results. The broader lesson is that road cleaning should not be measured only by the amount of dust collected or the number of machines deployed. Municipalities must measure how much dust remains on the roads, how quickly it returns, and whether the concentration of particulate matter decreases.

For a city like Delhi, where winter pollution can become a public health emergency, clean roads are not a complete solution. But it is a tangible civic intervention that can be planned, monitored, and improved. The true test of a clean road is not how it looks after a cleaning machine passes, but how much dust remains in the air afterward.
