City of Rockville

Dear Highly valued Customer, The City of Rockville is proud to provide this annual drinking water quality report following another successful yr during which Rockville’s water once again met or perhaps exceeded all government water quality rules limits. We ask you to review this kind of report for information about the source, treatment, division, safety and top quality of the city’s moving water. The city provides normal water and sewer to 70 percent of the town, or approximately 13, 000 accounts and 52, 000 community members. The Washington Suburban Sanitary Commission serves the rest of the metropolis. Within the past season, the city completed a $3 million building project to restore the 51-year-old Hunting Hill water storage space tank near Lakewood Country Club and the 55-year-old Carr Avenue container near Beall Grammar school. These tanks have got a combined potential of 11 mil gallons. Construction included safety upgrades, maintenance and/or replacement of the steel roof facilitates, interior and exterior work to eliminate old paint and repaint the reservoirs, the addition of a combining system in the Carr Avenue tank to help in meeting drinking water quality regulations, as well as the addition of a wifi communications antennae mounting framework to the Hunting Slope tank. The advancements will significantly lengthen the life of the containers, resulting in long-term cost benefits for city ratepayers. The Mayor and Council, as part of their very own vote on the Financial Year 2019 spending budget, adopted water prices for the next three years that will assist the city address it is aging water program. The rate increase is required so the city can certainly still repair and change aging water pipe joints and other infrastructure. Each of our water treatment herbs was first placed into the support 60 years ago, as well as original electrical devices have been used several years beyond the normal life span. The recently released $5 million Electric Distribution Systems Update project will substitute the plant’s electric switchgear, motor control centers and program with modern, high-efficiency equipment, resulting in improved reliability to produce and deliver potable normal water. The project happens to be in the design. The building is expected to come from 2020. We request you to learn more about Rockville’s drinking water at www. Rockville MD. gov/water and thank you for your continuing support of our quest to maintain the stability of the city’s drinking water system and provide secure, high-quality drinking water to the customers. Is my water safe? Metropolis of Rockville’s water to drink is safe, as established in the Environmental Protection Agency (EPA) codes and adopted and enforced by the Baltimore Department of the Environment (MDE). For the 2017 calendar year, the city’s water fulfilled or exceeded almost all water quality requirements. The Water Quality Info Table is shown on page 2 of this survey lists all the water to drink contaminants that were recognized. none of these pollutants exceeded the liquids' standards. This article will help to inform you regarding the quality of your normal water and includes specifics about where your drinking water comes from, what it is made up of and how it even compares to standards set by simply state and federal regulatory companies. Why are contaminants within my drinking water? Drinking water, which includes bottled water, may fairly be expected to consist of small amounts of a few contaminants. The presence of impurities does not necessarily signify that water creates a health risk. More information about pollution and potential wellbeing effects can be obtained simply by calling the ENVIRONMENTAL PROTECTION AGENCY Safe Drinking Water hotline by 1-800-426-4791. The reasons for drinking water (both regular faucet water and bottled water) include rivers, ponds, streams, ponds, reservoirs, springs and water wells. As water trips over the surface on the land or throughout the ground, it dissolves naturally-occurring minerals, and will pick up substances as a result of the presence of animals or perhaps from human activity, which includes: • Inorganic pollutants, such as salts and metals, which can be natural or result from downtown stormwater runoff, commercial or domestic sewage discharges, oil and gas creation, mining or harvesting. • Radioactive impurities, which can be naturally occurring or perhaps the result of oil and gas development and mining actions. • Microbial pollution, such as viruses and bacteria that may originate from wastewater treatment vegetation, septic systems, gardening livestock operations and wildlife. • & nitrogen-laden herbicides, which may are derived from a variety of sources including agriculture, urban stormwater runoff, and home uses. • Organic and natural chemical contaminants, which include synthetic and risky organic chemicals, that happen to be byproducts of industrial techniques and petroleum creation, and can also result from gas stations, urban stormwater runoff, and solid waste systems. To make certain that tap water is safe to imbibe, the EPA prescribes regulations that limit the number of certain pollutants in water given by public water devices. Food and Drug Administration (FDA) policies establish limits intended for contaminants in water in bottles, which must give you the same protection to get public health. Source normal water assessment and its supply MDE performed a source water evaluation of the Potomac Stream as it applies to the Rockville water grow. The 2002 statement may be obtained on the web or by getting in touch with the Water Supply System at MDE, toll-free Washington Blvd., Baltimore, MD 21230. You may also call 410-537-3589.

The City of Rockville’s Water Treatment Grow was put into services in 1958 and, at that time, was in a position of producing 4 mil gallons per day (MGD) of treated drinking water. The plant was improved in 1967 to improve production to 8 million dollars gallons per day. Inside the mid-1990s, and in 2017, additional upgrades towards the plant were made to fulfill EPA and MDE regulations. Since then, typically 5 million gallons per day of organic (untreated) water can be withdrawn from the Potomac River, treated in the plant and sent out to the city’s normal water customers. Once on the plant, the water is certainly put through a six-step treatment process to make certain it meets A safe drinking water supply Act standards. When treated, the water is usually sent through several underground water lines and water safe-keeping tanks and to the faucet. Screen Normal water from the Potomac Water is pumped by using a screen to remove huge debris such as stays, leaves, and stones. If algae flowers are present in the freshwater withdrawn from the river, it is cared for with potassium permanganate. Coagulation Water is treated with chemical substances that make small revoked particles stick with each other and settle from the water. This compound conglomerate is taken off the water before filtering. Sedimentation Water can be passed through a deciding basin or clarifier, allowing time for dirt, sand, metals and also another sediment to settle away. Filtration Water is certainly passed through a dual media (sand and anthracite) filter, which usually removes any leftover contaminants. Disinfection Chlorine is added the to kill and inactivate any staying pathogens. Fluoride is usually added to prevent teeth decay and a corrosion inhibitor is added to preserve the pipes that provide the water to homes and businesses. To Homes and Businesses, The treated drinking water is stored in two storage tanks which are gravity-fed to homes and businesses as needed. The water is tested at the plant, inside the distribution system with the tap in homes and businesses of lead, copper, different potentially harmful impurities, bacteria, and recurring chlorine..
