“The Carlsbad Desalination Project will provide San Diego county with a locally-controlled, drought-proof supply of high-quality water that meets or exceeds all state and federal drinking water standards.”
The quote above comes directly from carlsbaddesal.com,the website for Carlsbad’s new desalinating water plant. The process of desalination includes removing salt and unhealthy minerals from saline water. When discussing the current drought in California, there is often talk of desalination and its potential to increase our freshwater supply. Removing salt and minerals from saline water seems like an obvious solution to the drought and ongoing water scarcity concerns because it is a reliable water source.
Fourteen new desalination plants have been in the works to produce more drinkable water along the California coast. For many, this may seem like an answer to the “exceptional drought”. As consumers, it may also seem like a way to help us avoid making lifestyle changes, such as Governor Jerry Brown’s call for Californians to reduce their water use by 20 percent. But while desalination may be a reliable option, the answer is much more complicated.
One of the greatest issues with desalination is the cost associated with these projects. A new plant may cost upwards of hundreds of millions of dollars to build (a billion in the case of the Carlsbad facility), plus considerable cost to run the plant.
Beyond the costs to build these facilities, operational costs are substantial and raise concerns over the energy requirements and their impacts. Energy costs make up around a third of total operating costs for a typical desalination plant. In California, there is concern about vulnerability to short-term and long-term energy price increases. During a drought, energy prices tend to increase due to the reduced ability to generate hydropower and the need to replace that hydropower with more expensive energy sources. These costs are often overlooked and not always factored into the total project cost. Long term, energy prices are not static and may increase due to the rising costs of developing renewable alternatives and building and maintaining new and existing infrastructure.
With these high capital and operational costs also comes a higher cost of its product, water. Desalinated water can cost upwards of $1,900 per acre foot, considerably more than other alternatives such as water conservation and efficiency, stormwater capture, and recycled water.
Aside from the costs, there are other potential externalities associated with desalination facilities, including environmental impacts. Seawater intake systems that draw ocean water in through screened pipes impinge marine organisms on the intakes. Smaller organisms able to pass through, such as eggs, larvae, and plankton, are entrained into the plant and killed during the desalination process. Produced water disposal can also have a substantial threat to marine life. The salt is concentrated into a brine that is usually pumped back out to sea for disposal after going through the desalination process. These point sources increase salinity levels and may affect local sea life, depending on the plant’s location and sea currents.
The idea of building seawater desalination plants during a drought is not a new one. In 1991, a desalination plant in Santa Barbara was constructed in response to the 1987-1992 drought. Once the plant was completed, abundant rainfall rendered the plant cost-inefficient, and it shut down in 1992. Currently, costs to restart the plant are being assessed as the technology and infrastructure are dated and would incur new capital investment. Likewise, six seawater desalination plants were built in Australia in response to the Millennium Drought. Today, four out of the six plants are left idle due to the availability of cheaper alternatives. These examples should serve as cautionary tales.
The good news is that we still have cost-effective options readily available. A study by the Pacific Institute and NRDC shows how California’s drought can be managed with better allocation and management of water resources. By implementing water-saving practices, water reuse, and stormwater capture, California can save 5.2 to 7.1 million acre-feet of water each year in our urban areas – equivalent to the output of 125 large desalination plants!
Sustainable water management is best served by creating a comprehensive water management strategy in California, one that captures the most cost-effective options first. California has the ability to bridge the gap between water demand and supply by taking advantage of the existing resources and practices that have yet to be fully and efficiently harnessed.

Yesterday, the Wall Street Journal published an article about gray water. This type of recycling takes used water from bathtubs, showers, and sinks for lawn irrigation purposes. It filters the water after use and repurposes it to help lawns, gardens, and trees grow without using more water.
Californians have started to adopt this method of saving water in their homes. Businesses who sell and install gray water systems have increased their sales by 200%. The only downfall to these systems is that they can cost anywhere from $100 to $10,000 hard-earned dollars (or more).
But to some, the cost is worth it to save our environment. Ever since the drought started to effect the West Coast 4 years ago, Californians have been finding ways to save water and cut back on consumption. Sustainable water technology has also grown exponentially. Now there are many ways to save water in your home.
An alternative to using gray water is buying a water filter system for your entire home that reuses backwash water. If your filter recycles your water before it goes through your house, you’ll be preemptively saving water and preventing your family from using tap water (which has chemicals and contaminants).

As we all know, there’s a drought going on in Southern California. Local water monitors come through residential neighborhoods looking for culprits, boat owners can’t put in local lakes due to their shallowness, and signs are up everywhere pleading people to cut back on their water use. But humans need water to live, it’s a fact. So how do you drink enough water to stay hydrated while also contributing to lessen your water use during this drought? Here are a few tips to doing just that.
- Buy a filtering water bottle and stop buying bottled water. Firstly, some bottles leak chemicals from plastics, so you don’t really know what’s in your water. Secondly, the actual water itself can come from many different sources, so you don’t know what you’re putting in your body. And lastly, buying bottled water is not eco-friendly. 100 bottles= more trash than 1 BPA-free bottle re-used 100 times. It’ll also help you to drink more water if you carry a bottle everywhere.
- Drink a glass or two of water with every meal. Experts say that most of the time when you think you’re hungry, you’re actually just thirsty/dehydrated. So use that filtered water bottle you’re about to buy and fill it up a couple times before, during, and after your meal.
- Make sure you hydrate properly before, during, and after a workout. It’s hot out, and if you’re running outside you’re going to need to drink enough water to replenish your body’s 70% H2O makeup. It’s also a fact that drinking water helps to flush out the lactic acid in your muscles after a workout. So grab some water and drink up so that you aren’t as sore tomorrow.
Filtercon Technologies provides you with two great ways to save water and money while staying hydrated during this drought. Firstly, we have two different filtering water bottles that you can carry with you anywhere. One is from BPA-free and includes a carbon filter that takes out chlorine. The other is a stainless steel bottle that filters out bacteria. The other way that you can save money, water, and help your family stay healthy is to buy a whole house water filtration system for your home. It feeds filtered water to all of the pipes in your house while also re-using the water it backwashes with.

Sustainability is becoming more and more popular in our culture today. The term sustainability as defined by the Bruntland Report in 1987 (the first definition) is, “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Since 1987, we have developed far from just having a definition of sustainability. We have the resources and technology to measure and predict our use of nonrenewable resources. We also have the means to understand that humans are destroying our Earth at a rate so quickly that it cannot keep up or even recover.
Each human creates an ecological footprint that determines how our waste and energy use impacts the earth. There are so many ways that humans create their footprint without even recognizing it; by eating more meat, by buying new clothes regularly, by owning a home that has running water… these are just a few ways that we impact the Earth. If you’d like to see your individual impact on the Earth by figuring out your ecological footprint, check out the Global Footprint Network’s footprint calculator at http://www.footprintnetwork.org/en/index.php/GFN/page/calculators/.
Here are some tips to reducing your ecological footprint:
1) Eat less meat and buy more produce from local farmers
2) Use less water in your home and buy water-saving products
3) Use more public transportation and carpool often
4) Dispose of trash properly and recycle all reusable materials
5) Look into supporting your home with renewable energy like solar power
One way that you can reduce your water use is to buy a whole-house filtration system that doesn’t waste water. Filtercon Technologies has created a revolutionary system that reuses backwash to recycle water. Check it out at http://www.filtercon.com or call 800-550-1995 for more information.

Fracking, or the process of extracting oil from underground reservoirs, takes a lot of time, money, and water. But humans are extremely dependent on this technique because it brings out a natural resource that fuels transportation methods that we use in our everyday lives. Cars, buses, trains, and planes are just a few of the ways we get around that use oil as fuel. So how can a process that is so important still be so inefficient? Fracking wastes millions of gallons of water per year, water that could be reused for other purposes.
So why isn’t it being reused? Because when water is pressurized down into the ground to extract oil, it becomes contaminated and deemed “brimy”. This type of water is discarded into deep injection wells and new, clean water is bought to continue the fracking process.
Luckily a company that works with MIT has come up with a genius process to reuse some of these million gallons that are wasted every year. This company, called Gradient Corporation, has created a cost-effective process to treat brimy oilfield water for reuse. Depending on the location and type of fracking, carrier gas extraction (CGE) or selective chemical extraction (SCE) is used to clean the brimy water. Carrier gas extraction heats produced water into vapor and condenses it back into water without contaminants. In selective chemical extraction, chemical reactions remove specific contaminants. Both processes are effective, easy to use, and will save millions of dollars annually for fracking companies.
Reusing water is important, especially at a time when the West Coast is in a severe drought. It is important that every person does their part in helping to save water and save our environment. There are so many ways that you can save water, but one important way that also improves your health is to buy a water filtration system for your home that reuses backwash water. Think of it as your own system, like fracking, that can normally waste backwash water. Filtercon Technologies has developed a system that does just the opposite; reuses that water for other purposes while still purifying the water that goes into your home. Want to know more?

It’s inevitable that every system and process on Earth results in some sort of pollution. But thanks to an increase in education about water pollution, presently this is a growing concern. The definition of water pollution is a change in the quality of water, whether it be chemical, physical, or biological. Effects pollution can be harmful to those drinking or using it and particularly dangerous to humans.
Water pollution, ironically enough, mostly stems from human impact. Oil tankers and mines contribute greatly to water pollution. Other human sources include factories or sewage treatment plants.
How do can you tell if the water near you is polluted? Well, you can’t tell just by looking at it. The only sure way is to scientifically test a small sample. Many companies, like Filtercon for example, offer test kits to test your water at home for water pollution.
Here are some simple thing you can do in your life to prevent water from being polluted:
Rainwater can wash unsafe substances into nearby rivers, oceans, and other bodies of water. For this reason, try buying products that are not harmful to the environment. This includes BPA-free bottles, artificial air fresheners and disinfectants, chemical fertilizers, and flame retardants. You can find products that aren’t harmful to the environment in most local stores. If you use toxic products, simply dispose of them correctly (take them to hazardous waste sites) so they do not cause water pollution. Make sure that you aren’t dumping chemicals down the drain and check out your city’s local hazardous waste dropoff site.
Motor Oil and Cooking Oil
A good practice is not to allow your car to drip motor oil on the ground. Contact your local waste site and ask them when you can dispose of it properly to them. The same goes for cooking oil and paint, it’s a good idea not to put it down faucet. Many restaurants have a grease bin where they dispose of their cooking oil. If you can’t find a place to properly dispose of your cooking oil, ask a restaurant close by.
The best type of yard fertilizer for your yard is a non-toxic fertilizer, like compost. Toxic fertilizers turn into ocean and lake pollution when it rains. They can also be absorbed in the water supply, which is a result of poor drainage in the yard. It’s also good to not overwater your yard if you are using toxic fertilizer.
When walking your dog, clean up after him/her. It is courtesy, of course, but their stool sometimes can find their way to our water supply.
Some people use their toilet as a garbage can. Please do not make this mistake. It is polluting to add items like dirty diapers, sanitary napkins, and tampon applicators to your toilet drainage. These items could end up polluting the ocean and can damage the water treatment effort.
