HMWSSB's trenchless tech to detect water pollution in Hyderabad
HYDERABAD: The Hyderabad Metropolitan Water Supply and Sewerage Board is set to deploy the Quick Identification of Water Pollution Source, a pollution detection machine designed to pinpoint the source of water pollution in a given location, such as water pipelines and conduits. It utilises trenchless technology to examine pipelines without disruption and can help identify pollution issues and address them swiftly.
HMWSSB has invited expressions of interest from private manufacturing agencies with experience in the supply, delivery, and installation of QIWPS machines for any government sector. The scope covers the supply, delivery, commissioning and maintenance of QIWPS equipment for a period of five years.
The pollution detection machine will include an inspection camera, such as a self-levelling axial camera with a head and main body, and a CCD camera. The camera can operate up to 20 metres underwater and is equipped with high-brightness LEDs.
The QIWPS equipment includes a 120-metre-long fibreglass push cable and a stainless steel wheel with a built-in distance metre count encoder. It also comes equipped with an LCD screen, uses video encoding, and includes a wireless keyboard for data entry purposes.
The machine weighs between 23 to 28 kg, making it suitable for inspecting drinking water pipelines with diameters ranging from 60 mm to 300 mm. An Annual Maintenance Contract (AMC) is included for a period of five years.

All about Ohio bill seeking to restrict property rights of Green Card holders
Ohio lawmakers last month introduced two Bills seeking to prohibit foreign nationals and certain categories of Green Card holders from buying land near military installations and critical infrastructure. This came amid a larger trend in recent years of Republican-controlled US states moving to restrict the property rights of non-citizens citing concerns over national security and the necessity of controlling 'foreign influence'. A growing trend The Permanent Residency Card, more commonly known as the Green Card, gives holders the right to permanently live and work in the United States. As such, Green Card holders enjoy the same property rights as US citizens. But growing national security and economic concerns have prompted both federal and state lawmakers to scrutinise the ownership of American land by non-citizens. Between January 2023 and July 2024, at least 22 states enacted legislation restricting or regulating the purchase of agricultural land, critical infrastructure, and in some cases, residential or commercial property by foreign nationals, entities, or governments, said Sukanya Raman, country head, India of US-based immigration firm Davies & Associates LLC. Broader in scope The Republican-sponsored House Bill 1 and Senate Bill 88 in Ohio propose a 25-mile (roughly 40 km) restriction zone around military bases, power stations, water treatment plants, gas pipelines, and transport facilities. This list is broad enough to 'effectively blanket the entirety of the state of Ohio,' one Republican senator told local media. The Bills are also broader in scope than similar legislation enacted in states like Florida, Texas, Montana, and Utah. These states' laws have targeted designated 'foreign adversary' nations such as China, Iran, Russia, or North Korea, unlike the Ohio Bills which propose restrictions on all Green Card Holders, regardless of their country of origin. That said, provisions in previous drafts of the Bills requiring existing landowners from 'foreign adversary' countries to sell their property within two years have now been dropped. Legal challenge likely The Ohio Bills are still in their early stages, and could change significantly as they are put to vote in the state legislature over the coming months. But if passed in their current, maximalist form, they would restrict land ownership by all non-citizens, including legal permanent residents. This would be unprecedented in the US. To date, no federal law prohibits Indian Green Card holders from purchasing or owning land in the country. Under the Equal Protection Clause of the 14th Amendment, Green Card holders are entitled to due process and equal protection under the law. Any law or policy that discriminates against them based solely on immigration status may face constitutional challenges and be struck down, Raman says.

Civic body thirsts for 1cr switch to alkaline water in glass bottles
1 2 3 4 Ahmedabad: Only alkaline water, please! Ahmedabad Municipal Corporation (AMC) officials and councillors apparently want to ditch the plain old purified bottled water the corporation currently manufactures at its Kotarpur plant, and upgrade to alkaline water in glass bottles. This has been made evident from AMC water production department's May 29 tender for the upgrade and modification of the 3,000 LPH (litres per hour) packaged drinking water plant in Kotarpur, setting up a 1,200 BPH glass bottle water packaging plant and its operation and maintenance (production, storage, sale, distribution, logistics) for three years. The tender is for Rs 1 crore. There are also plans to market this alkaline water under AMC's existing drinking water brand, Jal. Sources in AMC said that a decade ago, officials, dignitaries and councillors at events such as inaugurations, seminars and meetings were served bottled water sourced externally, which cost the corporation Rs 40-50 lakh annually. To save this cost, AMC set up the plastic bottling plant in Kotarpur, and even launched the Jal brand. This plan to save citizens' money failed to work as intended. Other private brands still are roped in to supply drinking water, sometimes in glass bottles due to reasons including protocols on serving VVIPs. This costs the civic body Rs 20 to 25 lakh annually. Sources add that officials and councillors themselves are avoiding AMC's water brand, leading to 200 ml bottles being discontinued. On April 30 this year, a proposal to spend approximately Rs 1.50 crore annually on tea, snacks, meals and drinking water at govt events in the city was put up for approval. The proposal to award a rate contract for Rs 1 crore annually for tea, snacks, and meal packets at various AMC events was approved, while a proposal to spend Rs 50 lakh annually on bottled water was rejected, with instructions to retender. Now, AMC is processing the tender, rendering the current bottling plant ineffective. Caught in its own 'Jal jaal' Sources in AMC's health department said that a decade ago, as serving bottled water at events cost the civic body Rs 40 to 50 lakh a year, the then municipal commissioner, D Thara, approved a plan to set up a bottling plant for Rs 1.25 crore in Kotarpur. The plant, ready by 2014, remained non-operational for two years and in 2016, was activated under the brand name 'Jal', producing 200 ml, 500 ml, and 1,000 ml water bottles. These were sold at Amul parlours outside AMC gardens and served at corporation events. In 2019, when the central govt began implementing a phased ban on single-use plastics, the then civic chief, Vijay Nehra banned the 200 ml bottles of 'Jal'. After the responsibility for water arrangements at all AMC events was handed over to its health department, it went back to serving 200ml bottles, procured from private companies, defeating all environmental and cost-saving purposes, the sources said.

Vadaj land prices up 15-fold in 10 yrs, Kandla port trust surrenders plot
Ahmedabad: In proof of the city's booming real estate market, land prices in the western areas have skyrocketed over 15 times in just one decade, forcing Deendayal Port Trust (DPT) in Kandla to surrender a prime plot in Vadaj back to the Ahmedabad Municipal Corporation (AMC). Tired of too many ads? go ad free now This price increase came to light when the AMC's standing committee approved the DPT's request to surrender a 1,945 sq m plot in Vadaj village on Thursday. The plot, originally allocated in 2010 for a guesthouse at Rs 14,000 per sq m, was revalued at Rs 2,15,927 per sq m in 2020 — a 1,442% increase. If the plot were to be revalued again, the price could potentially be higher. The case dates back to July 2010 when the standing committee approved allocation of the plot in Naranpura TP Scheme No. 29 to DPT. The AMC set a reserve price of Rs 14,000 per sq m but included a condition requiring payment of any additional amount determined through govt revaluation. DPT initially deposited Rs 2.72 crore based on the reserve price and took possession in Jan 2011. However, the promised revaluation became a decade-long saga. "Despite the municipal corporation writing to the state govt's valuation department approximately eight times between 2010 and 2019, no assessment was conducted. The valuation finally occurred in 2020, revealing the huge price appreciation," an official said. "Following the 2020 valuation, DPT faced a massive financial burden. It was required to deposit Rs 39.27 crore to cover the price difference and an additional Rs 84 lakh for valuation process expenses. DPT appealed to pay up based on the old reserve price, but authorities rejected the request," the official added. DPT compounded its troubles by failing to fulfil the land agreement's construction requirement. Tired of too many ads? go ad free now The agreement mandated building construction within two years of possession for the designated purpose, but this was not done, in clear violation of the terms. So AMC ordered that the amount be deposited based on the valuation. It stated that proceedings to reclaim the plot will be initiated if DPT fails to deposit the amount. This prompted DPT to propose surrendering the property instead. "The standing committee's approval of DPT's proposal means the AMC will now reclaim the plot while returning the remaining amount to DPT after deducting valuation expenses from the amount deposited in 2010," an AMC official said.
