Water qualityPDF

States, territories and authorized tribes may adopt policies and provisions that generally affect the application and implementation of water quality standards, such as WQS variance policies/procedures, mixing-zone policies, and low-flow policies. Such policies are subject to EPA review and approval.

One of the principal objectives of the Clean Water Act is to “maintain the chemical, physical and biological integrity of the Nation's waters.” Antidegradation requirements provide a framework for maintaining and protecting water quality that has already been achieved.

Importance ofwater quality

Besides improving the comfort level of your water when your water pressure is too high, PRVs have a few additional benefits. Adding a PRV can reduce water waste and improve energy savings. Most of our clients experience savings on their utility bill when less water is rushing through the pipes for the same effect. In fact, our plumbers agree that high water pressure is the leading cause of slab leaks, broken fixtures (as many can only manage certain pressure levels), leaky faucets, broken pipes, water heaters, and water softeners. Just like blood pressure in your veins, high water pressure can weaken your pipes ability to hold the water.

Designated uses and water quality criteria are the primary tools states and authorized tribes use to achieve the objectives and goals of the Clean Water Act, and antidegradation requirements complement these tools by providing a framework for maintaining existing uses, for protecting waters that are of a higher quality than necessary to support the Clean Water Act goals, and for protecting waters identified by states and authorized tribes as Outstanding National Resource Waters (ONRWs).

Changing Water Pressure: You may notice that as you take a shower or do your dishes there will initially be high water pressure, but then it drops off starkly.

The WQS regulation requires states, territories and authorized tribes to specify goals and expectations for how each water body is used. Typical designated uses include:

The easiest way to determine if your Pressure Reducing Valve is working correctly would be to locate the arrow on the valve. This arrow indicates the direction of the water flow. This arrow should be pointing from the meter to your home or commercial property.

Another component to check is the material of your PRV. Instead, ensure your valve is made fully of brass. Many home builders use lower-quality valves; PRVs with plastic caps will often not even last a year. Finally, the reason many PRVs fail is that they are located in the ground which can be very corrosive.

Unfortunately, the city can increase your water pressure at any time to accommodate new construction. In fact, having a PRV has been mandatory for all homes in Austin with a PSI of 80 since 1980; however, each jurisdiction can override that regulation if they choose to. Homeowners in Austin can take advantage of a PRV rebate, provided by the City of Austin.

You should always replace your PRV when you notice any of the above issues, but depending on the quality of your valve, you may want to replace it every three to six years. The best PRV’s are made of solid brass, no plastic parts. Keep in mind that you won’t want to replace your valve within its first year of being installed due to a risk for corrosion.

Water quality standards (WQS) are provisions of state, territorial, authorized tribal or federal law approved by EPA that describe the desired condition of a water body and the means by which that condition will be protected or achieved. Water bodies can be used for purposes such as recreation (e.g. swimming and boating), scenic enjoyment, and fishing, and are the home to many aquatic organisms. To protect human health and aquatic life in these waters, states, territories and authorized tribes establish WQS. WQS form a legal basis for controlling pollutants entering the waters of the United States.

States, territories and authorized tribes also have the choice of including additional components in their water quality standards such as general policies and WQS variances.

States, territories and authorized tribes adopt water quality criteria to protect the designated uses of a water body. Water quality criteria can be numeric (e.g., the maximum pollutant concentration levels permitted in a water body) or narrative (e.g., a criterion that describes the desired conditions of a water body being “free from” certain negative conditions). States, territories and authorized tribes typically adopt both numeric and narrative criteria.

Water quality standards consist of three core components. This includes designated uses of a water body, criteria to protect designated uses, and antidegradation requirements to protect existing uses and high quality/high value waters.

Hammering Pipes: If your pipes are extremely noisy and make hammering sounds while your water is on, the water pressure is too high for your infrastructure to handle.

Bolt Issues: If you adjust the pressure using your Pressure Reducing Valve and the bolt on the valve breaks, it’s time to replace it.

PRVs are located near the shutoff valve on your main water supply line where the water enters your house. A PRV’s main job is to keep the water pressure stable, even when water events change the pressure. For example, fire fighting trucks use a ton of water to fight fires. Because of this, it can affect the water supply levels and sometimes disturb the existing water supply. A pressure reducing valve prevents the water from flowing backwards into your home’s water.

Pressure Reducing Valves, abbreviated as PRV, are valves that decrease incoming water pressure into your home. Although high water pressure is often seen as a positive, most homes should have a maximum PSI of 75. Anything above 75 can be detrimental to your comfort and home. Normal operating pressure is 60-65. This level of water pressure is more comfortable and better suited for your home’s infrastructure. Because of this, many homeowners choose to add PRVs to their homes for the health of their fixtures such as water heaters and RO systems.
