What Is a Rain Barrel? What is a rain barrel? A rain barrel is a container used to collect and store rainwater from your roof that would otherwise be lost to runoff and diverted out onto your property or to a storm drain and eventually to local streams or rivers. Rain barrels are also an economical way to store rain water to be used as a secondary water supply for indoor plants, flower gardens, lawns, fill the bird bath, and washing cars and windows. Rain barrels are usually about 40-60 gallons and can be purchased or made relatively easily. The parts are available at any hardware store. *Stored water is not used for drinking or bathing* Why use rain barrels? Every time it rains, unabsorbed water rushes to storm drains and directly into our local waterways. Often times this runoff carries with it pollutants it has picked up along the way depositing in them into local waterways. Any rainwater in an urban or suburban area that does not evaporate or infiltrate into the ground is considered stormwater. Infiltration is when water on the ground surface soaks into the soil. Impervious surfaces like roofs, asphalt, and concrete do not allow Rain water from your roof and driveway travels to the street and into storm drains for the infiltration to occur. eventually draining into our creeks, lakes, and rivers. Infiltration of water on pervious surfaces is important because it reduces the amount runoff and the possibility of erosion and pollutants leaving a site and entering a waterway. What can rain barrels do for you? Healthier plants. Rain water collected is Reduces the water bill. During the “soft water”, water that does not contain summer dry months water collected minerals and chemicals like chlorine, can be used as a supplementary calcium or fluorine. The chemicals provide water source for indoor and outdoor protection for consumers, but are plants, flower gardens, and unnecessary for lawns and gardens. landscaping care. Reduces the amount of water that settles around the foundation of a building. The water that pools at the bottom of a downspout outlet can be collected by a rain barrel and dispersed away from a building. What can rain barrels do for our watersheds? Every household can do its part for their watershed by reducing the amount of runoff coming from their property. Every time it rains, unabsorbed water rushes to storm drains and directly to local waterways. By collecting the stormwater from downspouts the cycle that allows precipitation from a roof to become stormwater runoff is broken. Pollutants such as pet waste, automotive fluids, sediment and fertilizer are kept on site and can be removed in an environmentally friendly way. What does a rain barrel look like? The basic design of a rain barrels consists of a container with an opening in the top of the barrel to collect the rain water from the downspout. The down spout is either connected directly to the top of the container or is placed over the opening. A spigot locate near the bottom of the barrel to allow for removal of the water in the barrel. There is also an overflow located near the top of the barrel. There is usually a screen or filter on the opening that keeps out mosquitoes, leaves, and other debris. What does a rain barrel look like? A good way to make your rain barrel more presentable is to paint it. Painted Rain Barrels How do I build my own rain barrel?

Ready-made rain barrels are available at several online sites.

Ace Hardware has rain barrels that can be purchased online and picked up at the store. How much rain water? How much water that will be collected at each downspout depends on the size and number of downspouts located on a roof. For a 1,000 square foot area during a 1” rainfall there is approximately 623 gallons of water that can be collected. Usually rain barrels are 40-60 gallon. Several rain barrels can be linked together to collect more rain water. Maintenance on your Rain Barrel During the rainy months, routinely inspect your rain barrel.

  • 2021 Rain Barrel Program
    2021 Rain Barrel Program This spring, LLCT and the Water Department/Water Commission are offering wholesale rain barrels through The Great American Rain Barrel Company (TGARBC). Order and pick up with LLCT’s Plant Kits on May 22nd from 8-11 A.M. at the DPW Site on Lewis Street. Water use has become an important issue in Lincoln. Recent years have seen drought conditions, and to protect the levels of our watershed, most summers and into fall residents have seen restrictions on outdoor water use. The largest residential water use is for watering lawns and gardens – according to the Lincoln Water Commission, our daily water use nearly doubles in the summer! Residents with wells might be surprised to learn that well water usage is also restricted, as that also drains the aquifer. There are many ways to conserve water use, and one ideal way to still provide water to necessary plants, including vegetable gardens, is to install rain barrels. Using rain barrels to water your gardens reduces the water drawn from our drinking water supply, allowing Lincoln to meet the DEP’s water conservation goals while simultaneously saving you money. That soft, chemical free water is very good for grass and other plants. During a rain storm, an enormous quantity of water runs off a roof, so you may want more than one! Each 4’ x 8’ section of roof that receives ¼” of rain will fill a 55-gallon barrel. TGARBC sells 100% re-purposed, food grade, UV protected and BPA free rain barrels. The barrels are produced in Massachusetts and will last for years when properly drained and stored for winter.

  • DID YOU KNOW? PET (Polyethylene Terephthalate) Is Actually Polyester. When PET Is Used for Bottles, Containers and Other
    355 Lexington Ave., Suite 1500 ▪ New York, NY 10017 ▪ www.PETresin.org DID YOU KNOW? Little-Known Facts about PET Plastic . PET (polyethylene terephthalate) is actually polyester. When PET is used for bottles, containers and other applications, it is called PET or PET resin. When PET is used as a fiber, it is typically called polyester. The PET bottle was invented by Nathaniel C. Wyeth, a DuPont engineer and brother of American painter Andrew Wyeth. The patent was issued to Wyeth in 1973 and assigned to DuPont. According to the EPA, recycling one pound of PET bottles (that’s about 10 two-liter soda bottles) saves approximately 26,000 BTUs of energy. PET bottles and the sun are helping millions of people in developing countries obtain potable water. Using a system called SODIS (solar water disinfection), inhabitants set water-filled PET bottles in the sun for several hours or days – depending on how much sunlight is available – as a simple but effective means of destroying disease-causing bacteria and gaining safe drinking water. More than 1.5 billion pounds of used PET bottles and containers are collected in the U.S. each year for recycling. PET is the most recycled plastic in the U.S. and the world. A single-serve PET bottle (0.5 liter) is strong enough to hold 50 times its weight in water. Chemists keep finding new ways to make PET lighter without losing any strength. A 2-liter PET bottle that weighed 68 grams in 1980 now weighs as little as 42 grams. The average weight of single-serve 0.5 liter PET water bottle is now 9.9 grams, nearly half of what it weighed in 2000.

Thus, material and component contamination is common. The most common source of resin contamination is water. Generally oil, grease and dust are observed in the contamination of products as well. Material Feed The feed to machines involved in processing thermoplastics is very often a mixture of virgin (new) material, regrind, and colorant (often in the form of a master batch). All of these materials must be kept clean and dry. A controlled ratio of the materials must also be used if consistent machine operation and component quality (such as surface appearance) are to be maintained. The extruder can be fed with plastics (resins) or compounds in various forms. The feed may be fine powder, regrind material or virgin pellets. If the material is available in more than one form, feeding problems will probably occur if a mixture of forms is used. In terms of feeding efficiency, spherical granules (of approximately 3 mm/0.125 in diameter) are the most efficient, while fine powders are usually the worst.
