Reverse Osmosis

A Note From Water Bob,

In 1978, I was fortunate to meet a man named                      at his membrane manufacturing plant in San Diego, CA. Don was the Father of Reverse Osmosis and designed the first household RO System. His input and guidance led to the start-up of Five Cities Water Systems. Thank you Don for your generosity and confidence! Today, More than 35 years later, we offer the best-made products on the market.  If you're interested in the best systems available on the market today, we have "3" choices to make drinking water as clean "as the clouds".
The most important thing I have learned in all my years in the water treatment industry, SERVICE is the reason customers come to our company.  We know that the customer appreciates the expertise of our professional service technicians and this forms a trust and a bond that is reinforced year after year. 
"We will not set equipment and FORGET IT and WE VALUE OUR CUSTOMERS!!!!"

So What is Reverse Osmosis?

Reverse osmosis, also known as hyperfiltration, is the finest filtration known. This process will allow the removal of particles as small as ions from a solution. Reverse osmosis is used to purify water and remove salts and other impurities in order to improve the color, taste, or properties of the fluid. It can be used to purify fluids such as ethanol and glycol, which will pass through the reverse osmosis membrane while rejecting other ions and contaminants from passing. The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications that are currently in place.
Reverse osmosis uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Most reverse osmosis technology uses a process known as crossflow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected species away from the membrane. The process of reverse osmosis requires a driving force to push the fluid through the membrane, and the most common force is pressure from a pump. The higher the pressure, the larger the driving force. As the concentration of the fluid being rejected increases, the driving force required to continue concentrating the fluid increases.
Reverse osmosis is capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 daltons. The separation of ions with reverse osmosis is aided by charged particles. This means that dissolved ions that carry a charge, such as salts, are more likely to be rejected by the membrane than those that are not charged, such as organics. The larger the charge and the larger the particle, the more likely it will be rejected.

What Sets Us Apart?


We like to pride ourselves on making our customers like part of the family.  We don't have customers, we have 15 year-long relationships. Each Reverse Osmosis System we place in the field needs to be serviced each year.  If you rent or purchase a system from our company, you will receive a phone call from us to service that system each year. We don't set it and forget it. Customers have our Reverse Osmosis Systems for good quality drinking water and the only way to maintain the quality of the water is to have the unit serviced in a professional, sanitary way. Every instruction manual for every Reverse Osmosis System on the market today outlines service guidelines.
Some water treatment companies develop a program that ignores service until the customer picks up the phone to complain about a problem.  We alleviate the customer having to think about anything because we maintain records and contact our customers every year for service.  Our customers express their appreciation of this service and also their appreciation of consistent quality from year to year. We Service Our Equipment Every Year!!!

Our Service program is the most comprehensive in the industry.  Great water quality is assured by servicing a system properly, testing the system each year, and sanitizing the system with each service. This yearly service, as well as the monthly recommendations we make to our customers, maintains a system that will produce the highest quality of drinking water possible, and let's face it - that's why you have a Reverse Osmosis System.


Don't forget your Leak Detectors!  

These little guys are similar to a smoke alarm and dispense a loud alarm if they detect moisture. 
Our customers love them!

Why have a Reverse Osmosis System?


You can reduce contaminants in your drinking water by 98%.

Why is that Necessary?

When I was attending college in 1974, The Safe Drinking Water Act was passed,

just four years after the EPA was created.

There are over 100 contaminants regulated by today's government guidelines.

Unfortunately, that fails to consider a wide scope of contaminants that are not yet being considered.
