MUST READ! ~ RUST IN MUNICIPAL WATERPIPES

RUSTPHOTOPAD

CONCERNED ABOUT RUST DAMAGE CAUSED BY YOUR HOME WATER ? – SEE END OF BLOG.

Excerpts from “Rust Never Sleeps” – A lack of pipe cleaning standards contributes to perennial corrosion issues, from Mar/Apr issue of WaterCanada by Randy Cooper.

If a corroded metallic water pipe is cleaned but not coated or lined, it will simply corrode again, often at an accelerated rate. As aging water assets reach the end of their lives, leaks, breaks, and decreased hydraulic performance are increasingly evident across Canada. RUST6PHOTOPADOld metallic pipes are often rife with rust (due to corrosion), sediment, old coatings, and even biological growth that can negatively affect water quality. BURST WATER MAINAs pipes become clogged, greater pressures are required to deliver water… In water main systems, we have main bursts.

“Burst water main spout 250 ft. fountain”, published Oct. 29, 2012 – A burst water main sends a massive jet of water the height of a 13-story building raining down over a suburb in Melbourne, Australia.
TRENCHLESS2One solution for aging pipes is to clean them out and reline them using TRENCHLESStrenchless technologies.      These operations entail digging small surgical pits in the ground to gain access to buried water pipes. Once the pipe is opened and properly cleaned, a new liner can be installed and secured…
LINING2Liners are typically designed to last fifty years, greatly improving water quality and quantity, and substantially lowering maintenance costs, including leakage, main breaks, and pumping costs.
RUSTY WATER FROM PIPESA whole new set of challenges emerges as we prepare to install pipe liners. Firstly, if a corroded metallic water pipe is cleaned but not coated or lined, it will simply corrode again, often at an accelerated rate, producing foul-tasting, “red”(rusty) water in the process. In other words, while cleaning is necessary, it does not exactly solve the problem. Secondly, if the old pipe is not properly cleaned and prepared prior to lining, the new liner may eventually leak again or even fail prematurely. It is not enough to clean the pipe – it has to be cleaned properly, and this is no small 
task. SCRAPERThere are many old methods for pipe cleaning, each of which provides strikingly different outcomes. They vary from simply swabbing a pipe using a foam plug to radical intervention using a powered, metal scraper…  A judgment call determines what is actually clean. There is seldom, if ever, any quantitative measure of “clean” or “surface preparation,” or “dryness” or  “liner bond.” In fact, these terms are not defined anywhere. There is no federal,  provincial, or professional standard, nor is there any recognized manual of best practices that provides a substantive, quantitative measure for cleaning old water pipes. Given the challenge of failing  infrastructure, there simply must be.

RELINING PIPEEvery pipe liner that is brought into service will see variations in water pressure over its life, from system operating pressures to test pressures and transient surge pressures (also known as water hammer). In addition, these liners will have to stand up under soil and traffic loads, continued corrosion, temperature swings, and variations in water chemistry. In order to keep them leak-free over their design lives and tightly conforming to the old pipe, good cleaning practices need to be standardized with quantitative, measured outcomes… NACE LOGOFor instance, the National Association of Corrosion Engineers (NACE) is a professional body with expertise in pipeline corrosion.  NACE promulgates standards for the cleanliness and protection of metallic  substrates (including pipelines) against corrosion prior to coating in many related applications. Similarly, the American Society for Testing and Materials produces standards for the testing of cleanliness and bond. The adaptation and  Incorporation of these established practices and standards into a pipe cleaning  standard just makes sense. So, what are we waiting for? Government and  professional associations need to step forward now to develop and implement  a cleaning standard at the dawn of this renewal era.

POURING WATER FROM THE AIR – NEW INVENTION

SOMETHING SPECIAL FOR OUR ‘TECHIE’ FOLLOWERS – AN AWARD WINNING INVENTION FOR COUNTRIES FACING

WATER SHORTAGES:

For those facing water shortages, there is much to be thankful for when it comes to the inventive spirit. Thanks to young Australian inventor Edward Linacre, there may one day be no such thing as a water shortage for Australian farmers.

He recently won the £10,000 international James Dyson Award for a “low-tech” device – the Airdrop – that can draw water from the air, besting the work of 500 other inventors.

Linacre, a graduate of Swinburne University of Technology in Melbourne, says he wanted to solve the drought problem afflicting farmers in parts of Australia suffering from drought conditions. His solution, Airdrop, can harvest 11.5 milliliters of water for every cubic meter of air in the driest deserts such as the Negev in Israel, which has an average relative air humidity of 64 percent. A small-scale prototype Linacre installed at his parents’ house created about a liter of water a day. Linacre will use his prize money for further testing on increasing the yield.

As reported in The Sydney Morning Herald, instead of using complex, energy-intensive methods such as desalination, Airdrop’s source of water is abundant – the air – and so it can be used anywhere in the world.

Linacre’s Airdrop delivers water to the roots of crops in dry areas by pushing air through a network of underground pipes, cooling it down to the point where water condenses. The water can then be pumped to the roots of plants using drip irrigation methods.

This video interview,

posted by gizmag, helps explain the invention and the sound reasoning behind it. Linacre say he was inspired by the Namib beetle, which survives in landscapes that get just half an inch of rain per year by consuming the dew it collects on the hydrophilic skin of its back. Similarly, the desert rhubarb can harvest 16 times the amount of water than other plants in its region by using deep water channeling cavities in its leaves.

James Dyson, whose charity sponsors the award, said that the device is a low-tech solution that could be installed and maintained by the farmers themselves; it powers itself using solar panels. Dyson offered this insight into the clever invention:

“Biomimicry is a powerful weapon in an engineer’s armory. We chose Edward’s project because it was a very good and original solution to what has become a real problem.”

In addition to Linacre’s cash prize, a further £10,000 has been awarded to Swinburne University. Linacre said without the university’s help he would never have got his idea off the ground.

The James Dyson Award is run by the James Dyson Foundation and each year students of product design, industrial design or design engineering from around the world are invited to enter.
