Your tenant number is the last two digits of what looks like your account number. Example. 12345678.00 98
The number 98 is the account holder's tenant number. A tenant number is how we keep track of who lives in the home. Our numbers begin with the first owner of the home (sometimes the builder) and the numbers decrease from there. The tenant number is vitally important to accessing your account online and to making payments because this is the only thing that differentiates you from all other customers who have previously lived in the home.
H²O Systems, inc. certified water operators collect monthly water samples from various locations in the distribution system. These samples are delivered to the State lab for analysis. If your water is unsafe to drink, you will be notified immediately - by door to door, notices on your door, media announcements and any other means available.
H²O Systems, Inc., has the right to remove any landscaping around our services that obscure the service from the street and/or blocks access to the services. If you wish to plant landscaping around our services, we suggest following these guidelines. Do not plant "creeping" and/or "travelling" landscaping around the services. This type of landscaping tends to obstruct the service from view and block access to the service. Do not plant large bushes and/or trees between the street and the service. This type of landscaping will obscure the service from the street and you will be asked to remove the landscaping immediately. Do not plant large bushes and/or trees within 24-36" of the service. Large bushes and trees tend to have large root systems. These root systems over time, will cause damage to the water and/or sewer lines in the vicinity of the service. Do not plant "prickly" bushes and/or trees, such as holly or sawgrass, within the vicinity of the service. This type of landscaping will block access to the service. Do not BURY your water and/or sewer services. Access to these services are viable to the operation of our company. Any buried and/or obscured services may cause problems with prompt responses during emergency situations. Under no circumstances should you plant obstructing landscaping around FIRE HYDRANTS. It is vital that firefighters be able to quickly and easily access fire hydrants during emergency situations. Any landscaping obscuring a fire hydrant will be removed by our personnel immediately. Other landscaping will be damaged upon use of the hydrant for either emergency situations or routine fire hydrant testing. If you have a question concerning your proposed and/or existing landscaping, please contact our office at 985-626-5132. We offer assistance and advise to those customers wishing to beautify their yards. We must work together with our customers for a pleasing and operational service area.
Generally, each home should have a shut-off valve located on their house line to turn the water off, inside the home, in case of leaks and/or ruptures in your house lines. The shut-off valve is located on the main line coming into your home. To locate your shut-off valve, walk around your home looking for a pipe that comes out of the ground and turns into your home. This line generally has an outside water faucet located on it, but it should also have an additional valve - this is your shut-off valve.

Some of your Questions

If you need help, we have a list of frequently asked questions and answers. We strive to give you the best buying experience possible. Click a question below to view the answer:

Is there fluoride in my water?

Your water contains trace amounts (very small amounts) of naturally-occurring fluoride. We do not add fluoride to your water.

What services are provided to our consumers?

H²O Systems, Inc., provides water and/or sewer to our consumers. We do not provide trash pickup, electricity, gas, cable or any other utility service. To find the provider for these services, we suggest contacting your homeowners association or look in the local phone book.

Why is my water discolored?

All services areas of H²O Systems, Inc., are provided water from aquifers (deep water wells). Deep water wells, also known as groundwater, contain naturally-occurring minerals which may cause problems with the color of your water. These minerals are called secondary contaminants by EPA because they have no known health effects at the quantities found in drinking water. For more information on secondary contaminants, see This site is a wonderful source of information for drinking water. The most common cause of color in our drinking water is a mineral known as manganese. Click here for more information. This mineral will turn your water a slight brown or tea color. It also forms scales on the inside of our lines and inside your home lines. These scales may cause a darker tint to your water and/or may look like rust or dirt coming through your water lines. To help remove manganese scales from your house line and clear any discoloration in your water, we suggest flushing your house line. See “How do I flush my house line?” below.

Why does my water taste and/or smell funny?

Hydrogen sulfide is a common element of all water systems in south Louisiana. This component of your water will cause a “rotten egg” or “sulfur” odor and a distaste to your water. Hydrogen sulfide is generally a problem in areas of your home that are not used a lot, such as your guest bathroom, or during periods of low water usage, such as while you are away on vacation or during vacancies of the home. If the smell and/or taste of your water has become objectionable, we suggest flushing your house lines. See “How do I flush my house line?” below.

How do I flush my house lines?

Flushing your house line is recommended only if you are experiencing discoloration, taste and/or odor problems on a continuous basis. To find out why the water inside your home has these problems, please see the answers above. For optimum results, we suggest your follow these guidelines …
1. Starting on the side of your home where the main water line enters your home (see How do I locate my shut-off valve?), begin turning your COLD WATER faucets on inside your home.
2. Once ALL of the COLD WATER faucets are on, at the same time throughout your home, let the water run for approximately 3-5 minutes. Then return to your first faucet & begin turning the water back off.
3. After flushing, allow your water to “settle” for 30-45 minutes for best results. We recommend that you flush your house line immediately prior to retiring for the night.
If you continue to have problems with the quality of your water, please contact our office at (985)626-5132 or email us.

Is my water meter read each month?

H²O Systems, Inc., strives to read every water meter each month. If your meter is not read, it could be due to emergency situations and/or your meter could be covered by construction or obscured by landscaping.
