IMPORTANT INFORMATION UNDERSTANDING YOUR PROPERTY LINE AND WATER SERVICE PIPE Your home’s property line is likely somewhere between the sidewalk and house (you can view property lines on DC Water’s Service Line Map at dcwater.com/servicemap). The homeowner owns the entire water service pipe and DC Water is responsible to maintain the portion in public space. The material of a water service pipe can vary from home to home in the District and some households still have lead service pipes.

LEAD PIPE REPLACEMENT During construction, DC Water will replace service lines in public space, and the lead or galvanized iron service line on your property if you agree to have it replaced. After a lead pipe replacement, a temporary increase in lead will likely occur in household tap water. We will flush your line outside and provide you instructions to flush inside your home and water filters to minimize exposure to any lead. • see page 6-8

BEFORE CONSTRUCTION MARKING UTILITIES WITH PAINT To prevent hitting underground utility lines, the law requires Miss Utility (missutility.net) to find and mark utilities with temporary paint before digging projects. You will see these paint markings on your lawn, sidewalk and street up to two weeks before construction. RELOCATING PLANTS AND SHRUBS You should temporarily move any favorite plants within five feet of the Miss Utility blue markings. Typically, the water service pipe should follow a straight line from the Miss Utility blue marking to the house. DC Water is not responsible for damaged plants. LOCATE AND MARK UNDERGROUND ITEMS Locate and mark underground items, such as electronic dog fences or irrigation systems that may interfere with the service pipe replacement, and be sure to notify the contractor. DC Water is not responsible for damage to these objects if they are not identified by the homeowner prior to construction. NO PARKING NOTIFICATION “No Parking” signs will be posted on your street 72 hours before construction begins. Signs will provide the dates and times for no parking in designated areas. In most cases, there will be restrictions on parking spaces. DC Water works closely with the District Department of Transportation (DDOT) to minimize street closures and traffic disruptions. WATER SERVICE SHUTOFF DC Water will provide a 48-hour notification prior to water service shutoff at your home. We recommend you collect a supply of water in advance for drinking and cooking purposes. ACCESS TO YOUR OUTSIDE FAUCET On the day of replacement, open the valve to an outside faucet and make the faucet available for use. This valve is usually located in your basement. After we replace or reconnect your water service, we will need to flush your water service pipe by opening the outside faucet. PROTECTING YOUR HOUSEHOLD PLUMBING You should contact a licensed plumber if you are concerned about your plumbing system or thermal expansion. The licensed plumber can inspect your plumbing system to determine your options for meeting the D.C. Plumbing Code’s requirements regarding thermal expansion. Household galvanized plumbing can also cause water quality issues, such as low pressure and discolored water.

DIGGING IN FRONT OF YOUR HOUSEHOLD During construction, we will be working in public space, but depending on the location of the property line, we may need to dig in your yard. The contractor may need to dig through lawns, sidewalks and streets. To minimize digging and avoid tree and root damage, the contractor will use a trenchless technology wherever possible. DC Water contractors take photographs of the repair area prior to construction to ensure it is properly restored. In most cases, your fence, retaining wall, porch or hedges will not be disturbed. In special circumstances, DC Water will work with a DDOT tree expert to develop a plan and work around major roots. INSTALLING A BACKFLOW PREVENTION DEVICE The DCRA Construction Codes Supplement of 2013 (2012 International Plumbing Code) requires the public water system to be designed, installed and maintained to prevent contamination from non-potable liquids, solids or gases being introduced into the public water supply. To comply with the D.C. Plumbing Code, DC Water will install a backflow prevention device in the outside water meter pit, during your water service pipe replacement. This device helps prevent contamination due to backflow into the public water system. TEMPORARY INTERRUPTIONS IN STREET AND SIDEWALK TRAFFIC Street and sidewalk traffic will be temporarily detoured during construction. All holes will be filled or covered with a plate at the end of each day. AVOID FLUSHING TOILET WHEN WATER IS SHUT OFF When the contractor disconnects your water service, the interruption to your water supply is typically less than two hours. During this time, avoid flushing your toilet – this prevents the toilet valve from clogging with debris.

HOUSEHOLD PL

FLUSHING FROM YOUR OUTSIDE FAUCET After construction, the contractor will flush your water service pipe through an outside faucet to remove pipe particles and other sediment. Sediment can dislodge from your plumbing during the pipe replacement process and reduce the flow of water in your home, particularly if you have older plumbing.

THE HOMEO THE HOME.

RESTORING THE WORK AREA DC Water contractors will restore areas behind the curb after pipe replacement (assuming no weather delays), including the sidewalk and your yard. DC Water contractors will re-seed lawns and tree spaces, and restore sidewalks. STREET RESTORATION Streets that are disturbed during construction will be patched and typically restored within 60 days. Some streets may require more than 60 days if additional work is scheduled and is dependent on weather conditions. DC Water is responsible for final repaving at completion of water main or street restoration work. INSTALLING A THERMAL EXPANSION DEVICE What is thermal expansion? Thermal expansion is an increase in water pressure that occurs when water is heated. This increase in pressure can cause leaks in household pipes and faucets, damage the water heater, and other plumbing problems. A thermal expansion device can prevent these issues. What is a thermal expansion device? A thermal expansion device safely manages changes in pressure caused by thermal expansion. This device helps prevent leaks and damage to a household plumbing system. What is backflow prevention? Backflow is the reverse flow of contaminants into the public water system. DCRA Construction Codes Supplement of 2013 (2012 International Plumbing Code) requires the public water system to be designed, installed and maintained to prevent contamination from non-potable liquids, solids or gases being introduced into the public water supply. To comply with the D.C. Plumbing Code, DC Water installs a backflow prevention device in the outside water meter pit during water service pipe replacement to prevent the reverse flow of water from your home into the public water system. This device creates a closed water system in your household and protects the public water supply from contamination. DCWATER . COM 4

When is a thermal expansion device required? The DCRA Construction Codes Supplement of 2013 (2012 International Plumbing Code) requires homeowners to have a thermal expansion device installed on their household plumbing system, when a backflow prevention device is installed on the water service pipe. As a result, all homeowners must ensure a thermal expansion device is installed on their plumbing system, after DC Water replaces their water service pipe. Some household plumbing systems already have a thermal expansion device installed. The most common device is a thermal expansion tank located near the water heater. If you are unsure a thermal expansion device is installed on your plumbing system, contact a licensed plumber to discuss their options. More Info For questions related to thermal expansion or backflow prevention, contact the DC Water Cross Connection Control Program at 202-612-3440 or [email protected]

HOUSEHOLD PLUMBING ISSUES THE HOMEOWNER IS RESPONSIBLE FOR ALL PLUMBING ON PRIVATE PROPERTY AND IN THE HOME. DISCOLORED WATER If older pipes are disturbed or sediment is dislodged during construction, you may experience discolored water. Run the cold water tap for according to detailed flushing instructions on page 7. Removing and cleaning faucet aerators will assist in flushing the sediment from your plumbing. HOUSEHOLD PLUMBING NOISES If air becomes trapped in the pipes, you may experience knocking, banging sounds or sudden bursts of water when you turn on the faucet. Run water through all your faucets and make sure valves under all your sinks are fully open. LOW WATER PRESSURE After construction, you may experience low water pressure if air or sediment becomes trapped in the pipe. If you have old household pipes, especially galvanized pipes, sediment build up can cause low or no water flow. In addition, a greater flow may cause older pipes to leak or even burst. After flushing the cold water tap, clean faucet aerators. You may need to contact a plumber to clean a blocked faucet. Contact a plumber to determine if you need to replace old pipes inside your home, especially galvanized pipes. If there is no water pressure throughout the entire house, please contact the DC Water 24-Hour Command Center at 202-612-3400. WATER HEATER DRIPS OR LEAKS If you experience pressure surges or high pressure, your water heater may leak after construction. Be sure the water heater thermostat, temperature and pressure valve are working properly by consulting with your owner’s manual or contacting a licensed plumber. GALVANIZED PIPES Galvanized pipes are old, iron pipes that were installed inside many homes built before the 1960s. These pipes can release lead in water if you have, or once had, a lead service pipe. When lead is released from a lead service pipe and passes through indoor galvanized plumbing (particularly over decades of use), lead can accumulate on the inside, corroded walls of this plumbing. Lead release from galvanized pipes can vary from home to home and can continue to occur even after the lead service pipe is replaced. Galvanized pipes can cause other water quality problems, such as low water pressure and discolored water. You should consider replacing galvanized plumbing with another plumbing material. Contact a licensed plumber about replacing household plumbing. If pipe replacement is not an option, use a water filter until all sources of lead have been removed. To learn more about galvanized plumbing, contact the Drinking Water Division at 202-612-3440.

LEAD, WATER AND YOUR HEALTH EXPOSURE TO LEAD IN DRINKING WATER CAN CAUSE SERIOUS HEALTH EFFECTS IN ALL AGE GROUPS. Infants and children can have decreases in IQ and attention span. Lead exposure can lead to new learning and behavior problems or exacerbate existing learning and behavior problems. The children of women who are exposed to lead before or during pregnancy can have increased risk of these adverse health effects. Adults can have increased risks of heart disease, high blood pressure, kidney or nervous system problems. The cutting or other physical disturbance of the lead pipe during service line work causes a spike in lead released into your water. Therefore, we strongly encourage homeowners to agree to replace the private side and public side of the service line at the same time. Also, for the homeowner’s awareness, the water service line pipe material must be disclosed when the home is sold and to all renters. Learn more at dcwater.com/lead.
