Taking a Green Glimpse at Aqua’s Eco-Friendly Initiatives

Now that we’ve covered the different processes by which Aqua treats and distributes water, it’s time to take a step back and look at how we keep it green. With Earth Day right around the corner, we were curious about all the eco-friendly and sustainable ways in which Aqua does its part for our planet. But first, we wanted to know: why is it so important to be “green” in the first place?

To find out, we spoke with Aqua team members Krista Scheirer, environmental specialist, Mark Bubel, project engineer, and Chris Crockett, vice president and chief environmental officer. And we’re not exaggerating when we say they gave us a lot to think about.

What’s all this talk about a carbon footprint?

You’ve probably read about this concept at some point, but every person, place and object in this world has a carbon footprint.

A carbon footprint is the amount of carbon dioxide each entity releases into the air and serves as a way of measuring our impact on the environment. The larger the carbon footprint, the greater the damage is to our environment.

What does Aqua think about all of this?

Because the decisions we make today are crucial to ensuring that we have reliable sources of drinking water in the future, Aqua is always on the lookout for improvement projects and opportunities that will help us function as sustainably as possible. In fact, our processes are already quite eco-friendly!

Good to know, but how exactly?

Let’s start with the easiest process: groundwater treatment. Because groundwater is typically quite clean from being filtered in the infiltration process, it doesn’t require too much work. So even when it does require some extra TLC, we’re able to keep our treatment’s carbon footprint to a minimum.

That’s not so hard. Right?

Well, surface water treatment is a bit trickier. We protect our surface water sources as much as possible, because the cleaner the water is when it reaches the treatment plants, the less chemicals and power are required to treat it.

Additionally, we use renewable energy at many of our treatment facilities (think: LED lighting and solar panels) and frequently replace old pipes and meters, which significantly reduces water loss.

Finally, remember the various materials (hint: mainly dirt) that get filtered out of surface water during the treatment process? Well, at Aqua, we are exploring “upcycling” those waste materials to make things like bricks.

Hold up. How can you prevent waste from going to waste?

Back in the third installation in our Aquastructure series, we talked about how microorganisms are dumped into the wastewater to get rid of organic matter containing carbon and nitrogen.

In order for these microorganisms to work, they need oxygen. So much, in fact, that feeding the microorganisms oxygen usually accounts for more than half of the energy used at the plants. (Yep, you read that right: HALF!) To improve efficiency and cut back on oxygen, we installed sensors that adjust and recirculate oxygen levels, which ensures that all our precious energy and oxygen isn’t going to waste. 

Meanwhile, those microorganisms are alive, so they begin to grow and reproduce, forming a nutrient-rich “sludge.” In the past, this sludge was pumped out of the tanks and sent straight to a landfill. However, we figured there must be a better way to deal with this sludge, so we found a solution to get rid of it once and for all.

This is where anaerobic digester tanks come in. These digesters mix and heat the sludge, which significantly reduces the remaining amount. The leftover bits and pieces of sludge can then be reused for fertilizer. Yum!

Ok, so it’s not so simple after all.

No, not really! And this only covers our eco-friendly practices when it comes to our treatment plants. At Aqua, we also host staff volunteer days for tree plantings, stream cleanups and habitat restorations. Our foundation contributes funding to dozens of environmental groups, and we work with more than 50 community organizations and regulatory agencies on water quality improvement projects.

Oh, and did we mention that Aqua facilities are home to many local ecosystems and endangered species? It’s true: From bird sanctuaries to diverse landscapes to valuable forests, we do our very best to protect these resources for the magnificent wildlife and aquatic life, and, of course, future generations.

Here’s the thing: Aqua completely relies on the health of our natural resources. Whatever we do to the land, the air or the water ultimately finds its way back into our wells and reservoirs. Aqua doesn’t just want to make sustainable decisions for the environment—we need to. 

 

Be sure to tune in next month when we jump into the current state of water infrastructure in the U.S. and discover how it impacts each and every one of us.

DIY Terrariums: Put Some Spring in Your Step!

Happy March! We’ve entered the final stretch of winter—some areas are still experiencing cold temperatures, but spring officially begins this month.

Now is the time to reintroduce green to your life by building your own terrarium. This simple and low-maintenance indoor garden will freshen up your home and spirit for the upcoming season.

What You’ll Need:

  • Sturdy, clear container
  • Pebbles for drainage
  • Potting soil or sand (no fertilizer)
  • Plants (succulents or mosses work well)
  • Decorations (optional)
  • Water and spray bottle for maintenance

 

What to Do:

 1. Consider using fun, unique containers to house your terrarium. Unexpected displays such as a domed glass cake tray, large conch shell or even a hollowed lightbulb can make your mini-garden reflect your style and fit in wherever you need more greenery.

2. Layer the bottom of your container with pebbles. This creates a drainage system for plant roots in case of overwatering. Adding potting charcoal can also be beneficial to some terrarium styles. This layer will help keep water free of impurities and prevent mold growth.

3. Fill your container with soil or sand, leaving enough space to house your plants or any decorations you plan on using. Fertilizer is not recommended for terrariums, since plants need to adjust to permanent soil and have limited space to grow.

4. Pick your plants. While many types of plants can thrive inside a terrarium, they have vastly different needs in soil, sunlight and water. It’s important to pick plants that best suit your living environment for stress-free care.

5. Make it your own! There’s an endless amount of accessories that can bring some personality to your new terrarium. Consider a woodland fantasy or Easter theme for spring. 

Aquatic Tips and Tricks

Keep a spray bottle full of water nearby to hydrate and refresh your plants. The force of water can easily disturb terrarium settings when it is poured from above.

Closed terrariums thrive in a humid environment. While some plant varieties can be fully self-sustaining, it’s important to keep an eye out for mold and occasionally allow the container to air out.

For a more aquatic look, plants like Anubias can be planted in tall vases and submerged in water. Once spring flowers begin to bloom, you can also preserve them in water and bring their beauty inside.
