Water is Life

Reuse - Recycle - Recharge - Reduce

जल प्रबंधन को ध्यान देने की आवश्यकता है: सामान्य नागरिक से लेकर प्रशासन तक। With rising population and uncertainties in weather patterns, water management needs a critical attention from everybody: ordinary citizen to the government. We all need to do our bit to address this concern and make the water available to all. One can get the monthly rainfall data for each state from 1901 to 2017 at data.gov.in/catalog/rainfall-india

Can we imagine the side effects of poor management of rainwater? It leads to destruction of road, inconvenience to travellers besides loss of invaluable life-saving and life-giving water!

शहरी घरों में पानी बर्बाद होने के तरीकों में से एक: हम सभी डिस्चार्ज पानी को एक छोटे टैंक में स्टोर कर सकते हैं और इसका इस्तेमाल बर्तन साफ ​​करने और कच्ची सब्जियों की सफाई करने के लिए भी कर सकते हैं। One of the way water is wasted in urban households is through discharge from RO-based water purifiers. We all can store the discharge water in a small tank and use it for cleaning utensils and even pre-cleaning of raw vegetables.

Be aware that the water discharged by the RO-system will certainly be purer than that in overhead tank. The water collection might cause some inconvenience but it is worth its value to save our planet! In most of Indian household, we have separate buckets which is used to store water and clean the floors. The buckets can be used to store the water discharged from the RO system. Some other methods: install water aerators to all taps or faucet (search for product Bubble Tap Aerator or Water Faucet Aerator Splash Proof Filter Anti-Splash).

वर्षा जल संचयन शब्दावली - Jargons / Nomenclature in Rainwater Harvesting

Area of Roof - छत का क्षेत्रफल: यह जमीन पर परियोजना क्षेत्र (लंबाई x चौड़ाई) को संदर्भित करता है और वास्तविक सतह के क्षेत्रफल को नहीं। - This refers to the project area (length x width) on the ground and not the actual surface area.

औसत वार्षिक वर्षा या वर्षा राशि (वर्षा की दर) - Mean Annual Rainfall or Precipitation Amount (Rate of Rainfall): यह प्रति यूनिट अनुमानित क्षेत्र में औसत बारिश है। - This is the average rain per unit projected area.

Run-off Factor or Run-off Coefficient:आमतौर पर यह उम्मीद की जाती है कि छतों पर गिरने वाले वर्षा जल का 100% एकत्र नहीं किया जा सकता है। - It is generally expected that 100% of rainwater falling on roofs cannot be collected. यह ड्रेन पाइप सिस्टम या बरसाती में अपरिहार्य छोटे रिसावों के कारण होता है - This is due to unavoidable small leakages in the gutter downpipe system or rainfalls which are too light to produce sufficient runoff or यह अत्यधिक बारिश के समय में अतिप्रवाह के कारण है - possible overflow in the case of an extreme downpour. For this reason, it is assumed that only 80~90% of the rainwater can be collected and referred as Run-Off Factor.

जलग्रह - Catchment: The catchment of a water harvesting system is the surface which directly receives the rainfall and provides water to the system. It can be a paved area like a terrace or courtyard of a building or open areas like a lawn or ground. जलग्रहण क्षेत्र वर्षा के संपर्क का पहला बिंदु है। टैंक-आधारित वर्षा जल संचयन प्रणाली के विशाल बहुमत के लिए, जलग्रहण क्षेत्र छत की सतह है। - The catchment area is the first point of contact for rainfall. For the vast majority of tank-based rainwater harvesting systems, the catchment area is the roof surface.

जलाशय - Reservoir: The final storage of rainwater for long-term use!

टंकी - Cistern: The local or temporary storage of water!

संग्रह गटर - Collection Gutter: पाइप की प्रणाली जो छत से गिरने वाले पानी को सिस्टर्न में स्थानांतरित करने के लिए उपयोग की जाती है। - The system of pipes and bends to transfer water falling from roof to the Cistern.

छत की ऊँचाई - Height of Roof: यह निस्पंदन से पहले छत के सबसे निचले बिंदु और पानी के भंडारण टैंक के बीच की ऊर्ध्वाधर दूरी है। - It is the vertical distance between the lowest point of the roof and the water storage tank before filtration.

Coarse mesh - मोटा /खुरदरा जाली: Installed at the roof to prevent the passage of debris.

Filter - छन्नी: A filter is used to remove suspended pollutants such as debris and dirt (silt and clay) from rainwater collected over roof. A filter unit is a chamber filled with filtering media such as fibre, coarse sand and gravel layers clean water before it enters the storage tank or recharge structure. Charcoal is added for additional filtration.

Bill-of-Material: Rain-water Harvesting System

There are many types of rainwater harvesting (RWH) systems: such as Roof Top Rain Water Harvesting (RTRWH) system, Ground Tank Rain Water Harvesting (GTRWH) system. Following table summarizes the items (commonly known as Bill-of-Material or BOM) for construction and commissioning of a typical rainwater system. Rainwater harvesting methods are site specific and hence it is difficult to give a generalised cost. As mentioned on webpage "rainwaterharvesting.org/urban/costs.htm" -the residents of Panchsheel Park Colony in Delhi pooled in Rs 4.5 lakh to harvest approx 170 million litres of water annually. Thus, the unit for cost of RWH can be [INR/kilo-Liter/p.a.] which turned out to be INR 3.75 per kilo-liter per annum.

Sample Bill-on-Material: Validation under process.

The costs of a RWH system would be comparatively significantly less if the system is incorporated during the construction of the building itself.

Rainwater Harvesting System and Water Saving Activities in Every Household

Water is undoubtedly one of our most precious resources. It sustains life, nourishes crops, and allows for the proper functioning of various human activities. However, with the ever-increasing population and the effects of climate change, the scarcity of water has become a pressing issue worldwide. In order to tackle this challenge, it is crucial for every household to adopt rainwater harvesting systems and engage in water-saving activities. By doing so, we not only contribute to the preservation of water supplies but also actively participate in sustainable living practices that benefit the planet.

Rainwater harvesting refers to collecting and storing rainwater for future use. This method has been practiced for centuries and is now gaining immense popularity in both rural and urban areas. The primary goal of rainwater harvesting is to capture rainwater runoff from rooftops, landscape areas, and other surfaces, thereby reducing the reliance on traditional water sources. Rainwater can be easily collected by using gutters, downspouts, and storage tanks connected to the household's plumbing system.

One of the significant advantages of rainwater harvesting is that it provides an alternative source of water for non-potable uses. This includes activities such as watering plants, washing cars, and flushing toilets. By utilizing rainwater for these purposes, households reduce their consumption of treated and expensive municipal water, leading to substantial cost savings over time. Moreover, rainwater is often free from pollutants and chemicals commonly found in tap water, making it ideal for various domestic applications.

To ensure the effectiveness of rainwater harvesting systems, it is essential to implement water-saving activities in every household. These activities involve adopting simple yet impactful measures to conserve water in our daily lives. For instance, turning off faucets while brushing teeth or shaving can save up to 4 gallons of water per minute. Similarly, fixing leaky pipes and taps promptly can prevent unnecessary water wastage. Installing low-flow showerheads and faucets can also significantly reduce water consumption without compromising functionality.

Efficient water usage in household chores is another effective way to save water. Utilizing washing machines and dishwashers with full loads, rather than running them half-empty, conserves a considerable amount of water. Additionally, reusing water from activities such as washing fruits and vegetables or capturing water used for cleaning can further reduce overall consumption. This recycled water can be utilized for irrigating plants or flushing toilets, thereby minimizing the demand for fresh water.

Incorporating sustainable landscaping practices is also crucial in water conservation efforts. Planting native and drought-resistant plants, using mulch to retain moisture, and installing efficient irrigation systems can significantly reduce outdoor water usage. These practices not only conserve water but also contribute to the preservation of local ecosystems and biodiversity.

Furthermore, educating every household member about the importance of water conservation and involving them in implementing water-saving measures is essential. By instilling these habits from a young age, we can contribute to a culture of sustainability in every household and create a collective impact in safeguarding our water resources for future generations.

In conclusion, rainwater harvesting systems and water-saving activities are vital components of sustainable living. Every household must actively engage in rainwater collection and utilize it for non-potable purposes. By adopting water-saving practices in our daily routines and incorporating efficient water usage in household chores and landscaping, we can make a significant difference in conserving water. This collective effort, alongside educational initiatives, will pave the way for a more sustainable future, where every drop of water counts.
