This picture I am submitting is on the side of the Target in my neighborhood, it’s a picture of 3 control valves for 3 different zones. These control valves control the flow/pressure of the water throughout the distribution system in this shopping center.

This picture I took is in the same shopping center as my other post, this is a double check valve assembly. These are specifically used for back flow prevention in the water distribution system for this shopping center. They prevent possible water contamination due to back pressure, and also prevent backward flow from a private plumbing system into public drinking water supply.

I saw these water distribution components in front of a municipal water district facility. I couldn't stop to get a better photo of a specific component, but I'm pretty sure the larger, some-what round tank is a pressure sand filter that filters out turbidity from the water. You can kind of make out some other components, like gate/shut off valves to stop the flow (they have hand-wheels), what look like pressure control valves, maybe, and the pump.

Hello class, please see the attached image for pictures of the valve covers in my residential neighborhood. Under the covers are valves similar to those that we explored around campus with Sam from Ventura College Facilities. These valves will turn water off being delivered to a specific area of the property in times of maintenance.

Hello class, please see my second image attached. This is a fire flow main that is attached to a portion of my residential neighborhood. It is associated with more than 10 structures and thus is quite large. You can also see that the middle section has the backflow device to prevent cross contamination Within the water distribution system.

In conjunction with my previous post, I took this photo across the street from the pump station- this is a fire backflow prevention assembly servicing a sheriff's department complex. Actually, I think the pipe in that photo runs to this backflow device. Backflow devices have check valves that prevent water from going back into the distribution system, prevention contamination via cross-connection. The handwheels are on shut-off valves in case the water needs to be shut off.

Backflow prevention devices stop contaminated water from flowing backward into the clean water supply. Their purpose is to protect public health by ensuring drinking water remains safe and free from pollutants.

A water meter measures the amount of water used by a home or building. Its purpose is to help utilities bill accurately and allow customers to monitor and manage their water consumption.

Hi class, the pictures I’m sharing are from Telephone Rd Plaza Shopping Center. A fire flow main is a pipeline that provides water for firefighting, ensuring sufficient pressure and volume during emergencies. The backflow device prevents contaminated water from flowing back into the potable water supply, maintaining water quality and safety. Additionally, I have listed some components from my photo:

1. Water from the main

2. Gate valves

3. Backflow preventer

4. Water service to building

Hi class, this picture is also from Telephone Rd Plaza Shopping Center. Here are two fire hydrants that are essential components of a community’s water supply system, providing firefighters with access to water to extinguish fires. I observed that one hydrant has two outlets (nozzles), which I imagine is to provide a higher water supply for high-hazard areas.

Here is a picture of a backflow device, a flow meter and three valves. The three valves are used to isolate both the backflow device and the flow meter. This is a very standard setup that is seen throughout the community.

Here is a picture of a water valve located at the Ventura Water Reclamation Facility. This is an older valve cover that is no longer used in the city. It is painted blue for staff to know it is for the potable water system at the facility.

# data[].attributes.attachment_caption
Although it is wastewater, I chose this facility because I drive up and down Harbor to get to work, school, home, etc, so I pass this facility almost every single day and thought I would share about it. This facility is used by the city to basically recycle water and operate the recycled water fill stations in order for the public to use. It handles the city's wastewater and is the source of its recycled water supply. 

# data[].attributes.attachment_caption
This picture is the main back flow for my work. I believe it is also apart of the bank right next door as well. There’s only 2 valves rather than the 3 that you typically see on normal setups through the community.

The photo shows two backflow prevention assemblies installed in parallel.

Specifically, each unit appears to be a Reduced Pressure Principal Backflow Preventer based on the visible relief valve housings. These devices prevent backflow and back-siphonage into the potable water system commonly used for the following applications.

Irrigation systems, Agricultural service connections and large commercial water meters.

Top assembly

• RP Backflow Preventer

• Two OS&Y gate valves one inlet, one outlet — identifiable by rising stems

• Relief valve vent on the center body

• Field test visible ports on the body

Bottom assembly

• Another RP Backflow Preventer

• Two gate valves

• Multiple test cocks for certification/testing

• Pressure gauges attached to test ports

This setup is at one of the Reservoirs that I pass to get to our location up on the Hill side. Some of the devices that we have learned in class and that you have seen if you’re in the field working already and if not, you’ve seen them from normally everyday driving or walking around.

Gate Valves (Red)

Used for isolation and are non-rising stem style.

Check Valves (Blue)

Prevent reverse flow back into the tank or system.

Positioned downstream of pump discharge lines.

Vertical Can Turbine Pumps or Well Style Pumps

These vertical turbine pump motors with column pipe below grade.

They lift water from a tank or wet well and pressurize distribution.

Air Release / Vacuum Break Valves

Used to release trapped air in the line and Admit air during draining to prevent vacuum collapse

And often installed on high points or discharge piping.

Pressure Gauges and Taps

Used for monitoring pump discharge and suction pressure.

Flow Control / Pump Discharge Manifold

The center piping branches from each pump into a common header.

This RP backflow preventer is one that I see every single day driving to work. The backflow device provides the highest protection for high hazard situations. They protect against back pressure and back siphonage. They are important to protecting the water distribution system.

This ultrasonic meter is currently used as a master meter for our recycled water program. We measure the flow that leaves our purple pipe to recycle water users. This specific meter uses ultrasonic technology which is sound waves and the waters speed to measure the flow.

Hi class, this is a photo of a backflow device near my work. This backflow device if a reduced pressure device(RP). The relief valve in the center, under the pipe indicates to me this is an RP. I believe this device is most likely for fire service. It also looks like there is a water meter upstream of the relief valve, maybe a Venturi meter.

Hi class, this is a photo of the water meter at my families property line where the main line connects to the service line. The water meter is a Neptune T-10 water meter which measures usage volume and monitors for leaks. I was curious why it doesn't seem to have a visible reading?
