MUST READ! ~ RUST IN MUNICIPAL WATERPIPES

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.

GREAT IDEAS FOR MOVING WARM WATER AROUND THE HOME

WATER PIPES

The following is an excerpt from the Nov./Dec. edition of Water Canada‘s magazine.

“Rethinking pumps and pipes” – Hot ideas for moving warm water around the home, by Michael Anschel and Kerry Freek.

Even though hot water can be the first or second largest use of energy in many homes, not a lot of thought is given to moving it through buildings efficiently. Add domestic hot water use, filtration, and distribution networks, and the energy value of water becomes significantly larger than generally acknowledged. Think about turning on a shower. In many homes, it takes three or four minutes for hot water to reach the point of use. Meanwhile, a large volume of treated, potable water, pumped at a great cost through aging municipal distribution networks to residential taps is lost down the drain. When you turn up the thermostat, hot water flows through the entire radiator system, not just the rooms which need heat. From the simple to the extreme, here are a few possibilities for saving water and energy while maintaining a steady supply of hot water in a home.

Picking efficient water heaters and pumps:  The first step in any home is to secure an efficient water heater. Generally speaking, there are four options: tank, tankless, combi, and hybrid. A tank heats water and stores it for when it’s needed.  At its best, it is 54 per cent efficient. Tankless and combi units can reach 98 per cent efficiency and eliminate the risk of combustion gas spillage in the home. Combi units have the added benefit of replacing your boiler, making them attractive from a cost perspective. Hybrid tank heaters are marginally more efficient than tank heaters at more cost, headache, and negative side effects… Over the years, pump technology has become increasingly more efficient – today’s pumps use a fraction of the energy that older models do. A smart pump could make a significant difference, radically improving an old system… A smart pump can also learn patterns and makes predictions. For example, if you wake up and take a shower at 7 a.m., the pump will run the line at 6:55 a.m. and, by the time you get to the shower, hot water is ready and waiting. The same pumps can send heat to your bedroom, bathroom, and kitchen in the morning selectively, rather than to the entire home…Re-circulating systems can provide some of these same benefits. The pumps that control these systems can be operated by switch, motion detector, or remote control. Pushing a small button on the way to the bathroom in the morning, for instance, could trigger a small pump that silently runs the hot water line, returning the cooler water in the line back to the tank and drawing piping hot water up to the shower valve so that it’s hot when you get there…

An efficient system is half the battle:  Switching from a tank to tankless system or replacing old model pumps with smart pumps may not make as much of an impact on energy bills if the delivery systems – that is, the pipes are inefficient. Switching an old 50 per cent efficient tank water heater to a high-efficiency tankless system will save energy, but in many cases even greater savings can be found by replacing or modifying inefficient delivery systems: the pipes. In many homes, the hot water heating station is a healthy distance from the point of use, such as a faucet. Residential systems may be better off with a new design approach – particularly in new construction. Here, the opportunity to completely rethink the layout of water pipes can yield the greatest amount of efficiency with the least amount of energy and resources…

Picking our battles: Understanding the value of a systems approach to hot water delivery and the opportunities that exist with high-efficiency smart pumps on our heating systems is an important first step. With minimal expense, we can easily modify existing systems and install new systems to be exponentially more efficient. We have an obligation to each other to make these changes a priority in our retrofit and new construction process.
