Father’s Day is an opportunity to tell dad how much you appreciate him. New dads, experienced dads, granddads, dads-in-law, stepdads, like-a-dads, girl dads, serious dads, goofball dads…There must be a million fatherly types out there, and without a doubt, there are at least that many reasons to honor them on Father’s Day said by Keely Chase. The San Jose Water District – Contract Monitoring Unit Family celebrates Father’s Day by giving some of our concessionaires a token of appreciation. #HappyFather’sDay

Astronaut drink
by Catherine Hours
The western French department of Vendee is joining the fray, announcing plans last month to turn wastewater into potable water by 2024.
The water will go though several stages of filtration and disinfection before being discharged into a reservoir.
"Everyone now understands that we must be frugal with groundwater" said Nicolas Garnier of Amorce, an association of cities.
In the past two years, 90 percent of communities in France have had to restrict water use due to droughts, Garnier said.
Europe represents a small percentage of the global recycled water market, according to Water Reuse Europe, a non-profit association.
It is five times more expensive to treat wastewater than water from a river or a lake because it is much dirtier, Connor said.
More than 80 percent of the world's wastewater is dumped in the environment without treatment, especially in poor countries, according to a 2017 UN report that called wastewater the "untapped resource".
"We have to find ways, especially in developing countries that don't have the funds, to pay to treat water", he said.
One way to reduce costs would be to take sludge from the treated water to obtain biogas or extract nutrients such as nitrogen and phosphorus which can be converted into fertiliser.
But the "yuck factor is not just for drinking", Connor said, even though the food people consumed has been safely grown thanks to reused water.
Connor points out that astronauts on the International Space Station drink water that was recovered from the crew's sweat and urine.
"No astronaut has ever gotten sick from the reuse of water"; he said.

A Project in Southern France recycles wastewater to irrigate fields
by Catherine Hours
Treating wastewater to put it back into public use can help against water crises around the world, according to the United Nations, though the practice has to overcome the "yuck" factor among the public.
Wastewater that has been through a treatment plant is typically discharged into rivers.
But there is a push to tap recycled water—also known as water "reuse"—in order to ease pressure on sources of freshwater threatened by growing populations, pollution and climate change.
Water reuse for sure will just increase and increase worldwide, because there's no other option," Richard Connor, editor-in-chief of the United Nations World Water Development Report published by UNESCO, told AFP.
Namibia's capital, Windhoek, has been a pioneer, transforming wastewater into potable water since the 1960s, while Singapore has also developed a much-vaunted recycling system.
A potable water project is in the works in western France.
Turning recycled water—also known as reclaimed water—into something you can drink is not the main purpose of the technology.
In Mediterranean countries as well as Texas and Mexico, reclaimed water is used for irrigation in agriculture, which consumes two-thirds of freshwater abstractions around the world.
