U.S. Water Week Highlights Technology and Water Protection

At Aqua, we know that water is the most essential resource to the world. Each day, the Aqua team works to provide clean, safe drinking water to the millions of people we serve, while at the same time being environmentally sustainable.

This year’s U.S. Water Week, which is recognized from April 15 to 21, focuses on how crucial it is to improve water and water infrastructure funding in the United States.

According to Aqua’s Chief Environmental Officer Chris Crockett, America’s current infrastructure is sorely neglected and failing: service outages are increasing, advance refunding has been taken away, and increasing regulations inhibit protection of our water resources.

Surprisingly, U.S. water usage has actually declined over the last decade or so. From 1996 to 2016, average annual indoor household water usage has decreased by 22 percent. However, staggering population growth, both in the U.S. and around the world, pose a serious challenge to declining natural water resources.

According to the World Resources Institute, a majority of the United States is under high risk concerning water quantity, which will have a short or long term impact on water being available to those living in the region.

Technology can help solve the water system challenges we are facing, but people have to advocate education efforts to policymakers about the importance of water infrastructure funding.

In order to think about water and all of its interconnections, Crockett asks us to think about how we would manage water and wastewater if we were to build a city from scratch. Think about the water cycle, the drinking water and fire suppression systems.

In the end, though, Crockett says that nothing beats nature.

“Nature must be more fully integrated into our communities to clean and protect drinking water as a first step,” he says. While technology will help us in solving some of the challenges our water infrastructure system faces, we need to focus on how we can help preserve the environment.

Aqua tries to make environmentally sustainable choices in everything we do, because we know the importance of water. By cleaning the wastewater produced by the communities we serve each day and returning this safe water back into local rivers, we work to prevent pollution, protect wildlife and champion the environment.

Plus, since 2005, we have partnered up with Treevitalize and the Pennsylvania Horticultural Society to plant 43,658 trees at 277 locations, and Aqua volunteers have been involved in cleaning up rivers and fundraising for fire departments.

It’s necessary to protect and preserve nature in order to maintain safe water for generations to come, and as a company, we’re proud to say our team continues to work year-round to do just that.

Why Water Mains Break

One of the biggest concerns for water utilities during extremely hot or cold weather is water main breaks. Water mains are expected to last a long time – as long as 100 years in many cases. But with many miles of pipe buried underground, it’s reasonable to expect a particular section of pipe will fail or break at some point. The challenge for water utilities is to work proactively to minimize the number of breaks and to respond effectively when a main does break.

While the oldest water mains were made of wood, by the late 1800s, a variety of iron pipe was being used to construct water distribution systems. Common iron varieties included cast and galvanized in the early part of the 20th Century, with galvanized used primarily for smaller diameter pipe. Cast iron pipe was used until the late 1950s when stronger, more flexible ductile iron pipe became common. Plastic pipe, including Polyvinyl Chloride (PVC) and High Density Polyethylene (HDPE) became common in the 1970s. The primary difference between these two plastic pipes is that PVC is stiffer than HDPE, which is more flexible. Even though pipe is expected to last for decades, that doesn’t mean it won’t break at some point. While it is impossible to predict specific pipe breaks, we know that environmental conditions are a major factor in water main breaks.

In the northern and northeast areas of the country where winters are more extreme, cold soils and cold water combine to add stress to pipes, which can—and often do—result in breaks. Iron, like all metals, contracts as temperatures drop. This problem is more common when the source water is surface water (rivers and lakes). These waters are significantly affected by air temperature and can drop to near freezing in the winter. A temperature difference of just 10 degrees in water or air temperatures can cause pipes to contract or expand. Additional stress inside and outside the pipe occurs as temperatures near the freezing point, making the pipe vulnerable to breakage. Water temperature changes more slowly than air temperature changes so the impact of cold water on pipes can cause breakage to take place as many as a couple days after temperatures freeze. Water systems with groundwater sources (wells) have more stable water temperatures because the water is not affected by air temperatures, and therefore, not as significantly impacted. 

Just as pipes are adversely affected by cold weather conditions, they are also affected by severe heat. In some groundwater systems in the southern and southwestern states, the soils are like sponges and hold lots of water. However, during extended periods of hot temperature when high demands for water increases water withdrawal from the aquifers, the soil becomes very dry. In these conditions, the soil contracts and subsides, pulling away from the pipe and diminishing support for the water main. The absence of support for the main can cause it to break. This particular problem led the City of Houston, Texas to begin to convert its groundwater supply to surface water.

Although older mains are generally more susceptible to breaks, breaks can occur on newer mains. This is most likely the result of improper installation or a manufacturing issue with that particular section of pipe. By examining trends in water main breaks over time, a utility is better able to identify categories of pipe that are more prone to breaks, and thus proactively target that pipe for replacement. Aqua employs such tactics in determining which mains to replace. By the end of 2013, Aqua expects to have spent $170 million of its $325 million capital improvement program on water main replacement and associated work.

5 Things You Didn’t Know Needed Water

1. Chocolate

Chocolate is many things – delicious, indulgent, maybe even addictive – but it’s also a heavy water user. Over 2,400 gallons are used to process just one pound of chocolate. 

 

2. Your Laptop

The average laptop uses the water of 70 washing-machine loads before it ever reaches your desk – including some stuff called “ultrapure water”.

 

3. Your iPhone battery 

Calling it “juice” isn’t that far off – charging a cell phone uses half a liter of water at the power plant supplying the electricity.

 

4. Your clothes

We’re not talking about throwing them in the washing machine – before you ever put it on, a cotton shirt uses 1,000 gallons of water in its manufacturing process, and a pair of jeans uses 900 during production.

 

5. Your car 

Building a new car uses a whopping 39,000 gallons of water, including the tires, which consume 2,000 gallons a set.

Top 10 Ways to Save Water This Summer

1. Make soup from cooking water. 

Who doesn’t love soup? Better question – who doesn’t love making soup more than a water-conscious superchef? Cooking, steaming, and blanching often leaves whole pots of water that is full of nutrients: throw in some stock ingredients, peas or lentils – whatever you love in a soup – and get cooking!

 

2. Water your lawn or garden from a rain barrel instead of the faucet.

As summer heats up, your garden is probably going to need more and more watering. You could spike your water bill by hooking up the hose or loading up your trusty watering can – or you can take advantage of the free water that literally falls from the sky by setting up a rainwater harvesting system. 

 

3. Ditch the hose for outdoor cleanup.

 

Summer means lots of outdoor work; it’s easy and really wasteful to hose away grass clippings and spilled soil from your driveway or patio. Instead, use an old broom at the end of a project to save water – and money!

 

4. Dehumidifier = Plant Water Machine.

Dehumidifiers are great for damp basements, and as an added perk, they give you a pretty much unlimited supply of instant free water for your plants or garden.

 

5. Wash your farmer’s market haul in a pot, instead of running water.

 

You probably wash fruits and veggies under running water. There’s a better way, and it’s pretty simple: Fill a pot. Wash your goodies. Use the leftover water to give your plants a drink.

 

6. Have a pool? Cover up!

No, we’re not urging modesty here – you do you! – but you should cover your pool when you’re not splashing or lounging. You’ll keep your water free of debris, but most importantly, you’ll keep water from evaporating away, especially on hot summer afternoons!

 

7. Don’t feed the weeds.

 

Healthy lawns and garden plants love a good drink. Unfortunately, so do weeds – and they’ll fight your plants for all the water. Getting rid of weeds regularly will keep your plants quenched and happy – plus it’ll save on water that would have been wasted on weeds!

 

8. Defrost frozen meats in the microwave, not under the tap.

If you’re not grilling this summer, you’re doing it wrong. Also doing it wrong: Running frozen foods under water to thaw them. Instead, turn to that king of kitchen efficiency – the microwave! It even has a setting for it and everything.

 

9. Handy with a wrench? Upgrade your shower head/faucet to a WaterSense model.

 

Modern shower heads save water without sacrificing the water pressure we all love. That WaterSense label means that the shower head performs at least as well as a standard model, while also being 20 percent more water efficient. It’s a satisfying project for a weekend afternoon, and you can save LOTS of water!

 

10. Use a shower bucket and put that cold water to work.

There’s no getting around it – your shower takes some time to warm up. So keep a bucket in the shower and fill it while the shower warms up. Once the water is warm enough, set the bucket aside, enjoy your shower, and afterward you can use that cold water for your plants or humidifier.

Diving In: Touring the Ashtabula Bunker Tank

The light-gray interior of the steel cylinder warped and echoed the near whispers of James Parker and Joseph Flahiff as they stood in a shaft of a daylight squeezed through a port hole far above their hard hats.

They were inside one of the city’s best-kept secrets, a structure whose interior rarely receives a human visitor. Surrounded by trees and a high fence, only neighbors and astute drivers know of the water tank, which has been off-line for the past month while interior restoration work was performed by Tank Industries Consultants of Indianapolis.

Parker, inspector with the company, and Flahiff, production manager for the tank’s owner, Aqua Ohio, opened the tank to a media tour. It was a rare chance to crawl inside a time capsule of sorts; the interior was last painted in the 1980s, although there have been periodic inspections that required human intrusion. 

Last year, two inspectors entered the tank from an access port and, using an inflatable raft, inspected the top section of the interior. The inspection was necessary to obtain a cost estimate for the interior painting job ordered by Aqua Ohio as part of its wide-reaching plan to upgrade the Ashtabula water system.

With the tank work nearly complete, Flahiff and Parker proudly showed off the fresh paint job as if they were unveiling a commissioned work of art. 

Repairs were made, the corrosion sandblasted away and an inert coating certified safe for potable water applied. Flahiff said coatings have improved greatly in the past 30 years, and the modern paint will do a better job of protecting the water supply.

The project is part of a major reinvestment plan to improve the area’s water treatment and distribution system. Aqua spent $1.4 million replacing pipe, valves and hydrants last year. Another $300,000 went into the chemical building at the treatment plant and $800,000 went for exterior painting and structural rehabilitation of the Bunker Hill tank.

All of the tanks provide a reserve of water and help maintain consistent pressure at faucets across the system, from a spacious Tudor on Bunker Hill to a bungalow on Lake Erie, where the water we take for granted begins and ends its journey.
