Rainwater has its important role in the ecosystem, in that it replenishes underground rivers, feeds plants and cleans soil pollutants. However, it seems natural that if saving drinking water is good both for economic reasons and for pollution reduction. Our grandparents used rainwater for all sorts of activities, so why couldnt we?
Design for Water: rainwater Harvesting, Stormwater
Water shortages are the worst nightmare of any city, and as summer is to come in a few months, they will be more likely to happen, at least in places like california. A team of researchers from Drexel University are encouraging people to harvest rainwater for flushing their toilets. They said that rain falling on cities like philadelphia, new York, plan seattle and Chicago is enough to flush toilets and spare potable water. People have been catching and using rain water for ages, but its only been in the last 20-30 years that we have realized that this is something that could be done systematically in certain urban areas to ease all different kinds of stresses on watersheds;. E., Phd, an associate professor in Drexels College of Engineering, and director of its Sustainable water Resource Engineering Lab, who led the research effort. The study looks at four of the largest metropolitan areas in the country to see if it rains enough to make implementation feasible and, if everyone did it, what effect it would for have on domestic water demand and stormwater runoff generation in those cities. The study started as the graduate thesis of Drexel alumnus Nathan Rostad, covers all sorts of scenarios, and is backed by numbers. It says that an average family would need a little more than a 1,000-gallon home storage tank laden with rainwater to cover over 80 of their flushes and save potable water. Philadelphia and seattle are the two cities where percent water savings would be greatest if residential neighborhoods were all equipped with rainwater harvesting systems, says the study. A lot of factors would have to be considered before implementing such a system.
Zamýšlím se nad rolí paper člověka v ekosystému přírody a tím, jak by mohl přispět k jeho zachování. Zjišťuji, co znamená voda pro člověka a jak moc je důležitou součástí našeho světa. Mým cílem je vytvoření instalace v daném prostoru, která se ztotožňuje s mými vzpomínkami a myšlenkami o vodě, jako základní součásti ekosystému planety a nás samých. Abstract-translated, in my bachelor's thesis I was inspired by rainwater harvesting system situated in my grandparents garden, which was the main playground of my childhood and remains the center of my childhood memories till nowadays. From describing the history of the house, the garden and my family i refer to my own experiences from childhood. Thesis deals with the role of a man in ecosystem of nature and ways that people can contribute to its pre-servation. Thesis looks for answers to question what the element of water means to humans and how important part of our world the water represents. My intention is to create instal-lation in given space. The installation is identified with my own memories and thoughts about water being a part of ecosystem of planet and ourselves.

Brad, thank you for this great analysis and for giving us a progressive alternative to traditional rain runoff solutions. Epilogue: Since completing his paper Brad has gone on to start his own rainwater harvesting company. Additionally, he has also discovered that the city of for Portland wanted to do a more progressive runoff management option, but a lawsuit and the epa forced their hand to do the big help Pipe. Since starting his business Brad has been able to leverage the spreadsheet he created for his paper to determine how much rainwater they could use. Brad says, "We determine as a result of the roof area and the number of people in their household the cistern will become empty every month. Often it does not matter what the cistern size is because of water consumption. I used to see this as a negative point, but I have come to realize that if a cistern is empty at the end of the month, it means all of the stormwater has been reused.
He continues, In the future i would like to work with the city of Portland to allow rainwater catchment to be accepted as way to deal with 100 of the stormwater on a site, thereby allowing homeowners to not have to install a drywell.". Full study and related topics. Název: faktory ovlivňující využívání systémů pro hospodaření s dešťovou vodou pro domácí potřebu pitné vody ve venkovských oblastech rozvojových zemí. Překlad názvu: Factors that influence the use of rainwater harvesting systems for domestic drinking water consumption in rural areas of developing countries. Autoři: Cahlíková, markéta ; novotný, josef (vedoucí práce) ; Lungová, kristýna (oponent typ dokumentu: Diplomové práce, rok: 2016, jazyk: cze, abstrakt: cze eng, tato diplomová práce pojednává o systémech pro sběr dešťové vody (rwh systémy fungujících za účelem dodávat kvalitní pitnou vodu pro domácí spotřebu.
By capturing the runoff onsite for later use, the storm surge would be greatly reduced and thereby potentially eliminate the system overflows. Brad structured a spreadsheet to analyze different tank sizes (e.g. 110, 500, 1,500, and 4,500 gallons) and different inside household water uses (e.g. Toilets, clothes washer, dishwasher, faucets, and shower and bath) against the monthly rainfall in the area. Surprisingly the analysis showed that two linked 55 gallon rain barrels would meet the needs of most households toilet flushing needs.
The most ideal cistern size for saving money and conserving water would be the 1,500-gallon cistern for both toilet and clothes washer use. This cistern would succeed for almost the same number of months as the 4,500 size, but it would cost less and have a better chance of fitting into an urban lot (either above or below ground). Using a 1,500-gallon cistern for toilet and clothes washing diverts 55 of the stormwater coming off a roof away from the stormwater system while reducing the strain on the municipal water supply during the dry summer months. In fact, if the city had given each person 3,000 to install a 1,500-gallon cistern, it could have mitigated the stormwater on site and saved the city money while inspiring a local rainwater catchment market. Brad compiled lots of very interesting and pertinent information in his thesis on rainwater catchment. In summary, brads thesis examines a large public works project versus a local rainwater catchment program and discovers that two linked fifty-five gallon rain barrels would dramatically reduce runoff and meet the toilet flushing needs for most households. This unique solution would reduce runoff, be cheaper, and delay the need for the big Pipe project.

Clean Water Act (CWA) standards. The treated water is released into the presentation river. If the css could handle the volume of water at all times, this system would comply with the cwa. Unfortunately, during large storm events, the added volume of rainfall overwhelms the wastewater treatment system. Stormwater combines with raw sewage in the combined stormwater and sewer pipe, which is then dumped into the willamette river, in violation of the cwa. According to the city of Portlands website, in a typical year, sewer overflows pour about.8 billion gallons of a mixture of stormwater runoff and raw sewage into the willamette through 42 pipes." This is in violation of epa standards and consequently the city needs. With a population of approximately 500,000 adults in Portland, approximately 2,000 will need to be paid by each person to pay for the big Pipe project. One way to minimize the water entering the css would to be to capture the rainwater coming off roofs and to divert it to indoor and/or outdoor water uses.
of water. This problem is compounded because storm runoff and sewer water are combined. Parking lot runoff is 16 times greater than runoff produced by a natural meadow of identical characteristics. Seattle receives about 40 inches of rain annually and the average residential lot sends about 9 inches as runoff versus 1 inch for a equivalent forested area. During large storms the added rain runoff overwhelms the system and consequently raw sewage and runoff are emptied untreated into the willamette river. In most of Portland, as is common in many cities, both the stormwater (i.e. Rain runoff) and wastewater (water leaving the household from the toilet, shower drain, sink drains, washing machines and dish washers) enter the same pipe and make up the combined sewer system (CSS). Large pipes take both of these products to wastewater treatment plants, where the wastewater is treated in a process monitored by the Environmental Protection Agency (EPA) to ensure it meets.
Reducing the thermal impact of storm surges to wildlife and surrounding vegetation. In the summer, the runoff areas can be 10-12 degrees warmer, which directly influence warming of the urban streams. Reducing the need and cost to filter and transport water gender back to homes for use. In fact, rain water is generally clean until it picks up pollution and debris along the way to the treatment plant. Increasing water efficiency awareness - something a large out of sight, out of mind project will likely never accomplish. The study compared the indoor water use of a sample neighborhood in Portland and discovered that just two fifty-five gallon rainbarrels would be enough to satisfy the toilet water use of most households. This small system could be used year round and have a definite impact on the rainwater runoff, diverting 30 of the stormwater in a year. The 2005 study leveraged data from a previous study on research on 100 households performed by the American Water Works Association.

Rainwater Catchment Systems may be better than the revelation big Pipe! By doug Pushard, in a recent research project by Brad Crowley, home-based cisterns were compared against the.4 billion Big Pipe program to upgrade the current Portland, or combined storm water and sewer system. At stake is a way to reduce the estimated.8 billion gallons of raw sewage and stormwater that is dumped annually into the willamette river. The study discovered that harvesting rainwater onsite may be a more cost-effective and environmentally sensitive approach to the public works projects. The purpose of the master thesis by Brad Crowley was to perform a neighborhoodbased rainwater catchment analysis using the city of Portland as an example, with emphasis on analyzing the impact if all single family residences used rainwater for key indoor functions rather than municipal. One of the key questions was: would a local neighborhood-based program actually reduce stormwater runoff to point where the costly and disruptive big Pipe project could be eliminated or postponed. The answer was yes! Besides eliminating the need for a massive project, other benefits of the smaller scale project included: Reducing of the amount of pollutants entering the watershed.
