Q. Does Loudoun Water handle garbage collection?
A. No, just water and sewer. Many people think because the word sanitation is part of our name, we have something to do with solid waste collection. This is not correct. Sanitation is a word that at one time referred to sewer systems. They were called sanitary sewers, and sometimes, that term is still used. Today, we usually refer to sanitary sewerage as wastewater collection or water reclamation. For information about waste handling or collection, contact the Loudoun County Office of Solid Waste Management at 703-777-0187 or go to www.co.loudoun.va.us/oswm.
Q. How can I be sure that my tap water is safe to drink?
A. Loudoun Water and all water utilities are very closely monitored and must meet stringent federal and state requirements for your drinking water. Assume your tap water is safe to drink unless you hear from us otherwise. You may also review our annual water quality report mailed to customers each year just prior to July 1. If you do not have a copy, or you have questions about the report, call customer service.
Q. How will I know if my water isnt safe to drink?
A. Taste, appearance and odor are not reliable means for determining whether your water is safe. We will notify you by local newspaper, by WTOP radio, and/or TV, if possible, if your water doesn't meet EPA or state standards. We will also attempt to notify you by roadside signage and/or hand-delivered flyers if there is an emergency. Our customer service department will likely extend hours of operation to take your calls during an emergency and that is the best first place to call. Next, listen to WTOP radio (107.7 FM) and look for roadside signs in your neighborhood. Do not rely on TV news or the website during an emergency. We cannot guarantee coverage or accuracy by TV news stations and during emergencies where power may be affected, the web may not be updated in a timely fashion.
Q. I have read about "intersex fish" in the news recently. Should I be worried about trace amounts of drugs or hormones in my drinking water?
A.

The U.S. Geological Survey reported the presence of “intersex” fish in the Potomac River. Our major supplier, Fairfax Water, wants you to know the following information:

  • There is no evidence of human health concern. Fairfax Water’s primary objective is the protection of public health through the delivery of high-quality drinking water.
  • Research has shown that the combination of the use of ozone and granular activated carbon are highly effective in removing broad categories of hormonally active constituents such as those discussed in the article. Fairfax Water uses both ozone and granular activated carbon as part of its multi-barrier approach that also includes coagulation, sedimentation, filtration and disinfection.
  • Fairfax Water, along with other water utilities regionally and nationally, is working to advance the science in the area understanding and treating endocrine disruptors.
    • Fairfax Water, along with the Washington Suburban Sanitary Commission and the Washington Aqueduct, founded the Potomac Partnership to study water quality issues in the Potomac watershed.
    • Fairfax Water, along with many water utilities across the nation, has contributed to and participated with the American Water Works Association Research Foundation (AWWARF) to study endocrine disruptors. To date, AWWARF has conducted 21 projects totaling approximately $4.9 million.

Fairfax Water will continue to work with regional and national partners to continue to advance the science regarding these issues.

Q. How can I get my water tested?
A. Please refer to our annual water quality report before you request a test of your water. This report contains information about constituents found in your drinking water and at what level. After you've read this report, you may still wish to test for specific items, such as bacteria or lead, since amounts can vary from house to house. Call customer service to arrange for a field service technician to test your water. Or, you may call your state certification officer to get a list of certified laboratories in Virginia. Depending on how many contaminants you test for, a water test can cost from $15 to hundreds of dollars.
Q. Who determines how safe drinking water must be and how is safety measured?
A. Under the authority of the Safe Drinking Water Act (SDWA), EPA sets standards for approximately 90 contaminants in drinking water. For each of these contaminants, EPA sets a legal limit, called a maximum contaminant level, or requires a certain treatment. Water suppliers are prohibited from providing water that doesn't meet these standards. Water that meets these standards is safe to drink.
Q. I dont like the taste/smell/appearance of my tap water, could there be something wrong with it?
A. Even when water meets EPA's standards, you may still not like its taste, smell, or appearance. EPA sets secondary standards based on these characteristics, which are not health hazards, and water systems and states can choose to adopt them. Common complaints about water include temporary cloudiness (typically caused by air bubbles) or chlorine taste, which can be improved by letting the water sit out exposed to the air.
Q. How do I know if the water pressure in my home is correct?
A. The Virginia Department of Health requires water utilities to maintain a minimum water pressure of 20 pounds per square inch (psi) within the distribution system. This ensures adequate pressure throughout your home, but not so much to add stress to your pipes. If the pressure at the service tap exceeds 80 psi, then provisions of the Uniform Statewide Building Code apply, which require the installation of a privately owned and maintained pressure-reducing valve (PRV). Most houses built after 1972 fall into this category and are already equipped with a PRV to keep pressure at or below 80 psi. The PRV is a bell-shaped device, approximately four inches in length, normally located near the main water valve of your home. If the water pressure in your home gets too high, it can cause stress to your pipes, causing them to knock or leak. If this is the case in your home, we recommend you check and if needed, adjust your PRV, or call a plumber to do so. If you do not have a PRV, it is recommended that you install one, as pressure can fluctuate throughout the distribution system.
Q. I am experiencing white specks in my water, or occasionally my faucets are clogged with white chips. What is causing this?
A. You may have a hot water heater problem. Defective internal dip tubes within your water heater may be the source of the chips. A federal district judge gave approval of a settlement against six national manufacturers of water heaters with defective plastic dip tubes. The manufacturers are Rheem, A.O., Smith, Bradford White, American Water Heater, Lochinvar, and State Industries. Loudoun Water has no involvement in the lawsuit or the process to get reimbursements or benefits from the settlement. For more information, contact your water heater manufacturer.
Q. Is the water safe for my baby, for cancer patients and for all populations? What if I have a severely compromised immune system?
A. Tap water, though treated to a high degree to meet strict standards, may still reasonably contain trace contaminants. Some people may be more vulnerable to these contaminants than the general population. People with severely compromised immune systems, such as people with cancer undergoing chemotherapy, people who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk for infections. If you or a loved one in your home falls into this category, ask your health care provider about drinking tap water.
Q. What should I do if I have my own drinking water well?
A. If you have your own well, you are responsible for making sure that your water is safe to drink. Private wells should be tested annually for nitrate and bacteria to detect contamination problems early. Test more frequently and for other contaminants, such as radon or pesticides, if you suspect a problem. Check with the Virginia Department of Health, Environmental Health Services, Well and Septic Department (703-246-2201).
Q. Is bottled water safe?
A. Yes, however, bottled water is not necessarily safer than your tap water. The standards EPA sets for the drinking water we provide are much stricter than the standards set by the Food and Drug Administration for bottled water. Consumers who choose to purchase bottled water should carefully read its label to understand what they are buying, whether it is a better taste, or a certain method of treatment. More information on bottled water is available from the International Bottled Water Association, which represents most U.S. bottlers.
Q. How long are we going to be in a drought?
A. Read our Top 10 Questions About the Drought Answered.
Q. Are home water treatment units effective?
A. Home treatment units may be effective at improving a particular taste or odor issue, however, they do not provide an increased measure of safety. In fact, if the treatment system is not maintained properly, bacteria can grow in the unit and contaminate the water. If you choose to purchase a home water treatment unit, carefully read its product information to understand what you are buying. Be certain to follow the manufacturer's instructions for operation and maintenance, especially changing the filter on a regular basis.
Q. Under what conditions would my water be turned off?
A. Occasionally, your service may be interrupted due to a water main break, a power outage or during long periods of freezing temperatures when meters freeze. Please call customer service if you are without water or call our after-hours emergency number.
Q. How much advanced notice do you need to set up/stop water service?
A. Just one business day. Call customer service by 2:00 pm the day before.
Q. Can you help me determine if I have a leak?
A. Yes, we can help you determine whether you might have a leak and we may even be able to help you locate the leak. We just can't fix it for you. Call us to set up a leak check appointment.
Q. Can you recommend a plumber?
A. We do not endorse any particular plumber. We recommend that you select a plumber by checking references, comparing prices and using information available from consumer affairs organizations.
Q. Why is my water milky or cloudy? Is it safe to drink and use?
A. If your tap water appears milky or cloudy, it is usually an indication of air in the system. This just means that somewhere in your area, we are flushing the system or a new line is being installed. Water mains are flushed by opening fire hydrants and allowing them to flow freely for a short period of time. The flushing cleans out sediment, which accumulates normally in the water mains. Another cause of air in the system is cold weather. Your water is still safe to drink and use. Allowing the water to stand for a minute will help clear it.
Q. Why does my water smell like chlorine?
A. Chlorine is used to disinfect your water. A slight taste of chlorine is a good thing - it means that likely no bacteria are alive in your water. You may notice a more intense chlorine taste and odor in your water when we flush the lines in the spring. This is because during flushing we use a stronger form of chlorine. Keeping an open container of water in the refrigerator for drinking helps dissipate a strong chlorine taste and odor.
Q. What causes the periodic spikes in my water bill?
A. Outdoor leaks are often the culprit for large, one time spikes in your bill. Silent toilet leaks are another common leak.
Q. Is there any relief from high bills caused by leaks?
A.

We offer a one-time adjustment for unusually high water charges caused by a leak. To be eligible for an adjustment, a customer must first call Loudoun Water to schedule a service call to verify the leak before a repair is made. To apply for this courtesy adjustment, send the following information to Loudoun Water, PO Box 4000, Leesburg, VA, 20177:

  • Your name, address, account number and daytime telephone
    number
  • A description of the type and exact location of the leak(s)
  • Proof of repair, such as a copy of a plumber's bill or a receipt for parts
  • The date the repair was made

We will try to respond within two weeks. For undetected leaks or for water wasted by damaged service pipe or fixtures, in which your consumption exceeds 130 percent of the average of the last three bills, a one-time adjustment may be made of 100 percent of the amount of excess in a bill due to this cause.

Q. What is the hardness of my water?
A. The hardness of water is determined by the amount of dissolved
minerals, primarily, calcium and magnesium. Loudoun Water customers receive water that is categorized as moderately hard. Moderately hard water does not seriously interfere with the use of water except in high pressure steam boilers and in some industrial processes.
Q. How is my drinking water disinfected?
A. Approximately one-third of the water we provide is chlorinated and the other two-thirds is disinfected through an ozone and chlorination combination.
Q. Is fluoride in my drinking water?
A. Yes, fluoride is added to the central system water to assist with the reduction of tooth decay in young children. Fluoride is not currently added to the drinking water at Lenah Run, Beacon Hill, The Reserve at Rokeby or Raspberry Falls.

Q. How can I prevent sewer backups?
A.

It’s a picture too ugly to imagine – the idea of raw sewage flooding your home. If you never want to see that happen, you must protect your sewer line. You can do this by ensuring nothing goes down the drain or flushed into the toilet that shouldn’t be. Items like cooking oil and pan grease should never be poured down the drain, nor should caustic liquid items, such as oven cleaner, or harder items like meat scraps, plastics or metals. Check out our online guide to disposing wastes wisely.

In the unfortunate case that this happens to you, Loudoun Water reminds customers that homeowners are responsible for any damage to their home caused by a clog in the lateral (which runs from your house to the street) or in the main sewer line in the street. Home insurance policies do not normally cover sewer backups into homes. For most policies, a rider is required. Contact your insurance provider for details on your policy.

Q. How can I be sure that the hydrants in my neighborhood will provide adequate protection in case of fire?
A. Loudoun Water conducts fire flow tests as part of the inspections process prior to the home's initial occupancy. Flow tests are preformed to measure real-world capacity in the water system, and how it responds to high demands. These tests are generally known as fire flow tests, because the highest demands occur when fighting a fire. A test is preformed by selecting three fire hydrants. A pressure gauge is placed on one hydrant, and water pressure is recorded. The remaining two hydrants are opened, allowing water to flow out as fast as possible. Each of these hydrants will flow between 1,000 and 4,000 gallons per minute. The pressure of the first hydrant is recorded again, and a drop in water pressure is measured. The results of a flow test allows design engineers to model their new developments to ensure adequate fire protection. In addition, these tests allow Loudoun Water to monitor water system capacity, ensuring quality service to customers.
Q. When will construction of the new line on Sterling Boulevard begin, how long will it take, and what is the estimated cost?
A.

The construction should begin in late 2005, early 2006. The project will be completed in phases over a few years. The estimated construction cost is $7 million.

Q. What is the purpose and need for a new main on Sterling Blvd? What makes this a five-year program?  How will this project benefit us? Who is paying for this project? Will we see an increase in our water rates?
A.

The purpose of the project is to improve the transmission of water in the Sterling area and to increase system reliability. There is a need for this project because the existing water main is undersized and one of the oldest pipes in the Loudoun Water system. This is a five-year program because that is the amount of time expected to complete the installation of 19,000 feet of water main in Sterling. This project will benefit you because of increased water system reliability, more stable water pressure, and better fire protection. The cost of the project is being paid for from availability fees, not from customer water bills. There will be no increase in your water rates as a result of this project.

Q. Where will the new Sterling water main be installed and what will happen to the old one?
A.

The new, larger water main will likely be installed on the edge of the service road, along the west side of Sterling Boulevard. The old water main will remain in service.

Q.

Will access to and from Sterling Boulevard be blocked during construction as you cross each intersection?  How will access to/from our homes be affected? When are you going to repave the roadway?  How will you advise the public of street closures and detours?

A.

VDOT generally does not allow intersections to be completely blocked by construction activity. Traffic will be able to access intersections, with the help of some flagmen and lane diversions. Since the work will be conducted in phases, most likely only one intersection will be worked on at any one time. Access will be provided to and from homes as part of a VDOT requirement. The repaving of the roadway will be coordinated with VDOT’s repaving schedule. A temporary patch will be provided by the contractor for daily use and then the road section repaved later, either in conjunction with VDOT or independently as part of the contract work. The public will be advised in advance of streets scheduled for work through mailings and street signage.

Q. What will be the impacts to Sterling Boulevard and other streets during the morning and afternoon rush hour while construction is underway?
A.

Traditionally, VDOT works in major intersections during periods of low traffic flow so that traffic during rush hours are minimally impacted.

Q. How will construction of the new Sterling Blvd main affect accessibility to Sterling Elementary School, Sterling Middle School and Park View High School?
A.

The proposed construction activity will be coordinated with the opening and closing times for schools in Sterling. All schools will be accessible for parents and buses.

Q. Will trees be removed or damaged during construction of the new main along Sterling Blvd?  If so, will these trees be replaced?  How will grassy areas, such as medians, be restored?
A.

Loudoun Water is working with the Sterling Foundation’s Sterling Boulevard beautification project. We will be restoring or replacing any impacted trees or medians within the Sterling Boulevard right-of-way in concert with their landscape plan. For trees on private property, the same commitment will be made.

Q. Will I experience any interruptions in my current water service during construction or changes in water pressure after construction? Should I expect any temporary service loss or loss of water quality?
A.

A temporary loss in service may occur while we work near your property and would last for only a short duration. There may be some cloudiness when the water is turned back on. Residents will be contacted when service to their home may be interrupted.

Q. What measures will be taken to ensure public safety in and around the work area?
A.

Loudoun Water, its consultants, and VDOT all have safety standards, which will serve as the foundation of all our work. All possible measures will be taken to ensure public safety in and around the work area.

Q. Did you look at alignments anywhere else except along Sterling Boulevard?
A.

There are no viable alternatives to replacing the Sterling Boulevard watermain. The Sterling Boulevard right-of-way provides room for alignment for the new main along the service road on the West side of the Boulevard.

Q. What are the anticipated daily hours of construction for the new main?
A.

The anticipated daily hours of construction are those of normal work hours. The exact work hours will be coordinated with VDOT and traffic conditions. Some intersections may require temporary night work to avoid traffic.

Q. Will construction of the new main be permitted on weekends or at night?
A. Only under special conditions is construction work expected on weekends or at nights.
Q. Where will materials and equipment be stored along Sterling Boulevard?
A.

VDOT generally does not allow the extended storage of materials and equipment within their right-of-way. So, materials and equipment are expected to be stored off site at locations to be determined during the design phase.
