With around 80 households, Bador is a small village located in Godda district of Jharkhand. The population here consists of a primitive Paharia tribal community that is recognised as a Particularly Vulnerable Tribal Group (PVTG). Like any other PVTG, this Paharia community also led a life of hardship for several reasons, including drinking water scarcity. The village had hand pumps and wells, but due to its location on a hill slope, the hand pumps would only provide water for three months and then go dry for the rest of the year. The wells were open, and due to their location on the slope, all the dirt rolled down from the hill and entered the well. The community was left with no choice but to consume dirty water from the well as there was no other drinking water source. The population suffered from a range of health issues like jaundice and cholera. The village also suffered from high infant mortality rate. A team from WaterAid India (WAI) and SATHEE first visited the community in 2014, and engaged the community people to understand their challenges related to access to clean water, safe sanitation, and hygiene. The team organised a joint meeting involving…

Madhava Manthri dam structure across Cauvery to be rebuilt for potable water.
MYSURU,May16: Consecutive droughts and fall in reservoir levels in Cauvery basin have hit both irrigation and drinking water needs of Bengaluru and other towns.
This has forced authorities to rebuild the 900-year-old Madhava Manthri dam into a concrete structure across the river.
The dam with about one tmcft of water storage will address drinking water scarcity to an extent.
Madhava Manthri is the main source of water for 56 villages in Malavalli taluk, Purigali lift irrigation that irrigates 30,000 acres in Malavalli, a source for Muduguthore lift irrigation covering parts of T Narsipur and Belagawadi and also for hydel power project in Hemmige.
The state government has prepared a detailed project report (DPR) and invited tenders to construct the dam at a cost of Rs 70 crore as any delay will badly hit these projects and put public to hardships during drought.
Meanwhile, the Irrigation Department has completed modernisation of Madhava Manthri left bank irrigation canal that would check seepage and ensure that the farmers in tail-end also get water.
As the Krishnaraja Sagar reservoir is completely dried up, the officials utilised the situation and have reset the sluice gates at all the three levels in order to avoid wastage of water.
They have also completed modernisation of Ullahalli and Rampura canals in Kabini achukat.
Cauvery Niravari Nigam managing director Shivashankar said the water storage in these dams would be a great relief to meet drinking water needs of Bengaluru and other towns.

BRYN MAWR, PA, MAY 16, 2016 — Aqua America (Aqua) is recognizing Infrastructure Week, May 15-19, 2017, to help raise awareness about the significant need for investment in the United States’ water infrastructure.
With plans to invest $450 million in 2017, Aqua will help rebuild and replace water infrastructure in the communities it serves.
Projects are planned across all eight of Aqua’s states to ensure clean and safe water reaches each customer.
Between 2012 and 2016, Aqua invested $1.5 billion in infrastructure renewal, including replacement of more than 700 miles of water mains.
"As a leading water utility, our number one priority is delivering safe, reliable drinking water to our customers," said Bill Ross, senior vice president, engineering and environmental affairs.
The 2017 American Society for Civil Engineers Infrastructure Report Card ranked the United States’ drinking water and wastewater infrastructure "D" and "D+" and illustrates the following challenges: Drinking water is delivered via one million miles of pipes across the country, but many of those pipes are approaching 100 years in age There are an estimated 240,000 water main breaks per year in the United States, wasting more than two trillion gallons of treated drinking water It is estimated that leaky, aging pipes waste 14 to 18 percent of each day’s treated water, which could support 15 million households Aqua’s 2017 infrastructure investment plan includes replacing 150 miles of water mains across eight states, helping to save billions of gallons of water leaking from pipes and water mains.
"Aqua employees understand the challenges facing the nation over the next few decades, and we work every day to do our part to help revitalize the nation’s infrastructure," said Ross.

Far fewer people in Bangladesh have safe water than the state government has estimated, new research shows. In addition, many people who do not have access to safe drinking water are under the mistaken impression that their water is safe, drinkable, and clean. According to the latest national assessment, 85 percent of the people in Bangladesh have access to safe drinking water. However, the new research uncovers two major problems that the national statistics don’t reflect. “The most surprising and disturbing result of this research was discovering that, in the communities we studied, there was almost no reliable year-round access to safe drinking water, while most residents did not know that their water…

Borealis and Borouge, the OPEC Fund for International Development (OFID), and the the UK Government’s Department for International Development have funded a project that has helped bring safe and affordable drinking water to more than 50,000 people in Kenya. The Water for the World project was intended at Kenya’s capital Nairobi, where an estimated 60% of the population have little access to water and sanitation. The partnership has worked to improve drinking water supplies in Korogocho and Kahawa Soweto informal settlements of Nairobi. The usage of polyethylene (PE) pipes allowed to install pre-paid water dispensers, which would…

Is bottled water better than tap water?
Here are eight things to know about bottled water in Singapore: 1.
And more brands have recently been added to the shelves, including two brands of alkaline water which were introduced at the Sheng Siong supermarket chain in 2016.
They are natural mineral water, packaged drinking water, mineralised drinking water, distilled water and spring water.
Chlorine concerns Some have switched to drinking bottled water due to worries over chlorine levels in tap water, but experts have said the level of chlorine in Singapore’s tap water is within acceptable limits.
Is it better for health?
According to a study published in the BMC Public Health journal in 2004, water with minerals was found to lower the blood pressure of people with low urinary excretion of magnesium or calcium.
However, experts told The Straits Times that more conclusive results are needed to support claims that alkaline water and oxygenated water are better for health.
Fluoride levels may pose risks to children Dr Wuang Shy Chyi, domain lead for water technology at Temasek Polytechnic’s School of Applied Science, said that due to their natural sources, mineral water can contain trace amounts of elements.
Associate Professor Richard Webster from Nanyang Technological University’s School of Physical and Mathematical Sciences said that water marketed as artesian or untouched by humans is not better, describing it as a "marketing gimmick".

Neighbors complain they have not had clean water in a year.
Neighbors at the Arundel Mobile Home Park told KREM 2 they have been told for years to not drink the water or even bathe in it.
“It’s ruining my clothes, it ruins my household appliances,” said Bruce Mullen, a resident.
People living in the trailer park said they have gotten notices to not drink the water, simply because it is not clean.
Some people said the owners of the park have compensated them for bottled drinking water.
“Then all the sudden, we’ve got no pressure,” said Dan Quine, another resident.
An employee told KREM 2 they are "following the rules" and directed all other questions to the Idaho Department of Environmental Quality (DEQ).
The Idaho DEQ confirmed the trailer park is under a bottled water advisory, due to the fact their well water supply is “under direct influence of the Spokane River.” Suzanna Scheidt Miller, a senior drinking water analyst for Idaho DEQ in Coeur d’Alene confirmed a treatment system had been installed for the trailer park, but “it was determined earlier this month that the treatment did not sufficiently produce water meeting minimum treatment.” She said the issue became apparent when the river levels were recently elevated.
Miller said the DEQ met with the owner and a project engineer on Friday to talk about the water issue at Arundel, and to “evaluate other options to provide water uses with potable water as expeditiously as possible.” Miller said the owner of Arendel is required to give residents connected to Well #1 bottled water or reimbursement for bottled water until they remove the bottled water advisory.
“It makes me angry that my kids can’t go and get a cup of water,” said Amy Dillon, another resident.
