All You Need to Know About Rainwater Harvesting in Delhi

rwh3

Our team had a chat with officials at The Rain Centre, R.K. Puram and Force, the NGO that has partnered with the Delhi Jal Board to implement rain water harvesting in Delhi, to get clarity on what actually needs to be done.

For those unaware of the problem and the mandate, we request you to read through our previous blog:Introduction to Rain Water Harvesting.  Rain water Harvesting has now become mandatory for all residential houses that are 500 sq. meters and above. There are 2 rules to observe here:

  1. It is compulsory and there is no way you can shy away from implementing a Rain water Harvesting System if your house is 500 sq. Mtrs. or over.
  2. You need to construct an underground water storage tank connecting all the drains on the roof. You may construct more than one if all the drains cannot be connected to one. The formula for the storage tank is as follows:

Rooftop area (in sq meters) X 0.8 (this is the runoff coefficient. Basically it is believed that 80% of the rain water runs off and can be collected) X 0.025 (as it is believed that Delhi receives an average rainfall of .25 mm per hour).

 

This formula will give you the volume of the rain water harvesting pit in Cubic meters. This volume will be calculated from the lowest part of the inlet pipe, to the top most layer of the filter media of the ground water recharge pit. Here again, it is recommended that you build a recharge pit and not a mere storage pit, though the Delhi Jal Board doesn’t mandate the building of a recharge pit. However, it is recommended, so that the water keeps percolating into the ground and doesn’t overflow much.  The point to note here is that the Delhi Jal Board hasn’t specified any set dimensions for the pit/pits as long as the total volume of water collected is basis the above formula.

 

Delhi Jal Board Roof Top Definition for Rainwater Harvesting

A rooftop is any area that is exposed to rain, and from where water can be collected.  So, any terrace or landing exposed to rain water will be considered a roof. Currently, the Delhi Jal Board has only come out with a mandate for Roof Top Water Harvesting, so if you aren’t just looking at complying with the policy, you could also collect surface level water.

 

Rainwater Harvesting Recharge Pit Filtration

In case you plan to build a ground water recharge pit, it is suggested you add the following filter media in the specified layers so that the water percolates slowly and is purified in the process:

Layer 3: Brick Bats

Layer 2: Bajri/Gravel or Coarse Charcoal

Layer 1: Sand

 

You could also merely use Jute bags, but you would have to change them every year, as they would disintegrate. The point to note here is, that the thickness of the filter media needs to be 80 cm.

 

If you plan to build a mere Storage Tank, you would need to build a concrete floor for the tank as well. In this case, you will need to keep track of the overflow as well, during the rainy season.

 

Rainwater Harvesting Storage Tank Overflow

To manage overflows, one needs to ensure that there is an over flow pipe. This overflow pipe needs to connect to the garden in the house or an open area where the water can be absorbed. It should definitely not connect to the sewage system of the house or the mcd drains; else, it will get wasted. If you have a borewell in the house, you could also connect the overflow pipe to the borewell.

 

Delhi Rainwater Harvesting Penalty

If you decide to ignore or procrastinate implementing rain Water Harvesting in Delhi by September end, then your Delhi Jal Board Bill will increase by 50%. To avoid this penalty, you need to implement the above, and share the design of your storage tank, as well as a top view design of your entire plot, specifying the plumbing, to get clearance. This letter, along with the aforementioned designs, needs to be sent to the revenue department of the Jal Board. As soon as you send this letter, you wouldn’t be liable to pay any penalty, and can get is waived off by showing a copy of the same to the collection authority or specifying the same on the Delhi Jalboard helpline numbers.

 

Even though the penalty will be waived off as soon as the letter is sent, random checks will happen at a later date, to ensure that you have complied with the policy.

Tips on Being Considerate Towards Neighbours During Renovations

noisy neighbours

noisy neighbours

We all live in a closed society, amongst neighbours, and are interdependent on them. It is therefore, extremely important for all of us to ensure that we care for our neighbours. Many a times, we ignore our neighbours’ convenience while constructing and renovating our homes and offices. This isn’t really unethical, but being considerate would certainly go a long way in building a relationship with your neighbours. Here are a few tips on how you could be a bit thoughtful and integrate your neighbours’ conveniences while planning your project:

1)    Inform your neighbours’ about your renovation project and the scope of the same, weeks in advance. Say, you are planning to change the tiles of your apartment along with other things, the neighbours below should know about the dates when the same would happen, so that they can plan accordingly.

2)    Discuss the work schedule you have in mind, with your neighbours. They may have guests on certain days, or may have a baby or an elderly person at home who needs to be shifted out during the process. Some people may work in shifts and may find it inconvenient if your construction work takes place on certain days. Try and accommodate their needs as much as you can, and be extra sensitive if you have a baby or an elderly person as a neighbour.

3)    Share your contact details and that of your contractor, especially if you plan to shift out during the renovation process. This will communicate to your neighbours, that you will lend a ear in case they face any problems during the construction process.

4)    Let your contractor know how important the convenience of your neighbours is, to you. Ensure he addresses any concerns they have, especially those related to seepage, cleanliness, the work schedule, and the parking areas used by construction vehicles and the contractors etc.

5)    If your renovation process causes any damage to their premises, ensure your contractor tries to rectify the same, without charging them.

 

6)    If possible, invite your neighbours for dinner once your project is complete, so that they get a chance to see your new home/office.

All in all, try putting yourself in your neighbours’ shoes and make your renovation process as seamless as possible for them. If you cannot reach out to them for whatever reason, ensure that you don’t schedule any renovation that would result in excessive noise (demolition, marble work etc.) before 9.30 am, and post 8pm. If you can, also avoid the afternoon nap hours as well.

That said, some neighbours are never happy no matter what you do, so don’t fret over them excessively.

Home Office Ideas in Small Spaces

Work is no longer a 9-5 ordeal, and we often tend to bring back things to do. As a result it’s important that we have our working nook in the house so we can isolate work and personal space as much as possible.

 

  • The room under the stairs: The space, the famous Harry Potter lived in, can be well utilised to carve out a fancy work space. If you are a space optimiser freak, you could also build a cabinet in the staircase.

  • The landing between the stairs: This usually is the most under utilised space, as it is used more as a pathway between the rooms. However, this space could be used to build an unobtrusive work area with a table built in within a cabinet, and a chair.

  • Folding tables in cabinet: Tables take a lot of space, but a book shelf with a folding cabinet can really cut a lot of space while creating an office like nook, when one wants to work or transforming into a library of sorts, otherwise.

Renovation before the Monsoons

monsoon home

While many people curse the monsoons for stalling construction, the rains prove to be a good test of the quality of the construction.

roof1

  • Testing the Waterproofing: Monsoons are the best time to test your waterproofing without having to fill up the basement or the roof with water, manually, to test the seepage. You can easily check for leakages and see where the water is seeping from and take corrective measures.

Roof-drain-system

  • Testing the plumbing and drainage: While building, it’s important to check if the water is draining right and if the roof is slanting correctly. It’s important to check that the water doesn’t collect anywhere and then alter drainage, accordingly. Monsoons are the best time for such tests. This is also a good time to test the drain pipes and check for blockages.

wood swelling

  • Woodwork: wood tends to swell in the monsoons, hence it is a good idea to wax or oil the wood before the rains arrive. In any case, the wood may swell a bit, and it is important to cater to the same, before fixing the same in the house.
  • There is usually a gap between the floor and the door, through which rain water tends to get in. Monsoon is a good time to check this and build a mount or add a rubber contraption to the door to stop the water from entering the house.
  •  Walls: Monsoons are the perfect time to check all the interior walls, especially those in the bathroom and the kitchen, for any spots of dampness so that if there are any cracks these can be repaired and waterproofed right away.

Do take care of these three factors, while planning your renovation project.

2) Droplet Sprinklers

Water sprinkler systems for the garden are known to waste a large amount of water! The droplet sprinkler is one of a few solutions that’s helping cut that wastage significantly, and also saving energy by combining robotics, with cloud services. It is known to reduce a garden’s water consumption by as much as ninety percent per year. All one needs to do is to attach it to the water supply, set it up using your smartphone, and then configure the device on the Droplet website to tell the system about the plants you have. Their vast data network takes over and tells the sprinkler when, where and how much water to sprinkle.

ecomise

3) Ecoisme

Ecoisme is a single sensor, intelligent home energy monitoring system that tracks the energy consumption of all devices in your house. It then gives you recommendations on reducing energy usage. What’s fascinating is that it claims to be able to alert you about things like forgetting to close your fridge door, or leaving the iron on. Ecoisme was crowd funded through Indiegogo and is currently under development. I’m sure its being eagerly awaited!

nest

4) Nest Smart Thermostat System

The Nest is one device you’ve probably heard or read about at some point. Typical thermostats are built within devices like air conditioners, and require you to manually program them to adjust the temperature each time. They, however, cannot sense people around. The Nest uses sensors and algorithms to understand who and how many people have entered or exited the house, and automatically adjusts the settings for you. So you’re no longer left worrying about whether you’ve turned off the AC or heating when you leave the house. Thus saving you money while offering plenty of convenience.

5) Water Pebble

The pebble is a little stone that you place in your shower, and it helps you reduce your shower water consumption. It starts by baselining the amount of water you are using, and then day-by-day helps you bring down the usage by training you to use less water. It can bring you down to one third of your normal usage, thereby saving a fair bit in time.

While most Indian homes are probably not ready for all these devices just yet, we hope you enjoy reading about some of these cutting edge consumer products in the energy space. We can only hope that some of them hit our markets soon.

How to Reduce Your Electricity Bill by 25%

Energy Efficiency
With all the hullabaloo about Green Tech and Energy Conservation, carbon footprints, and all the smart and geeky sounding jargon, we decided to take some baby steps and speak to Arjun Gupta, about how he helps conserve energy in commercial buildings. What came out, were a bunch of interesting data points, insights and tips.
What Made you Start Smart Joules? 
 
Arjun: Quite Simple. The fact that we end up wasting at least 25% of energy consumed because of inefficiencies, saving which, would not only make energy available to those who need it most, but also save money for building owners and eliminate the need for constructing additional power plants.
So How Do You Actually Help Save Energy? What, in Layman Terms, Do You Do? 
 
Arjun: Smart Joules took birth with the realization that most companies prioritize running their systems at any cost, rather than optimizing their energy consumption to maintain the desired service levels. Even if companies know how to save energy, they typically lack the financial and/or human resources to be able to implement energy saving measures. That’s where Smart Joules comes in. We offer 360 degree solutions when it comes to saving energy. From evaluating energy requirement vis-a-vis consumption, to monitoring wastage, to evaluating the areas where wastage could be reduced, and installing our perceptive energy optimization systems, to financing the project, we do it all.
How Much Do Companies End Up Saving, Month on Month?
Arjun: Well, they end up saving minimum 15% and 25% on an average. For our customers, that means Rs 10,000 or more every day. Smart Joules charges a fixed percentage of the savings for a fixed period of time, typically five years.
How Does India fare, Basis International Standards of Energy Consumption?
 
Arjun: If you look at the Energy Performance Index of commercial buildings, India stands at250-300 kWh/sqm/yr, where as the international standard is around 150 kWh/sqm/yr.
So we are lagging far behind. 
Arjun: Yes.
Do you have any simple tips on how we could catch up? 
 
Arjun: Of course. Not going into the basics, using LED Lights etc…The first place to look is blocking air and water leakages, improving operations and following proper maintenance procedures. Keeping an explicit building energy manager within the maintenance team will go a long way, and will more than pay for the position. Low cost solutions such as painting the roof-tops white, or using reflective paint on the exteriors, helps in reducing air conditioning load. Importantly, using less Glass, in a country like India, helps remarkably. Glass wall exteriors end up creating a Green House effect, dramatically increasing the Air Conditioning costs.
In fact, Super Efficient Buildings can cut electricity costs by more than half.

Planning to Go Solar? Get Your Questions Answered Here

Green planet earth with solar energy batteries installed on it

Solar Energy is one of those amazing solutions to a perennial and growing problem, and even though many of us want to adopt it, the dearth of information and relatively high installation costs kill the urge in the crib.

Our chat with Kanika Khanna, broke a lot of misconceptions regarding harnessing and suing Solar Energy. To give you a little background, Kanika has done her Bachelors in engineering from Delhi College of Engineering (DCE), and her masters from Massachusetts Institute of Technology (MIT), and has worked with Cummins in the US, in the manufacturing sector.

Q: Hi Kanika, It’s great to have you enlighten us about Solar Energy, and how we can harness it. To begin with, what are the pre-requisites one needs to bear in mind when planning to install a solar panel?
Kanika: Well, all you really need is a Electricity connection and a roof that you own. Typically, a panel generating 3kw of energy requires 250 square ft of shade free space. But if that’s not available, you could build super structures or solar pergolas,for the panels.
Q: How does one calculate how much energy should the solar panel generate, to bring down the electricity costs significantly?
Kanika: We follow a few thumb rules here. Typically, from my experience, a 3Kw panel reduces the bill by roughly Rs 3000 per month. This typically helps you break even by 6 years. A 5 Kw system, similarly, helps you break even in less than 5 years. Since a solar panel system lasts for at least 25 years, this turns out to be a huge saving, as solar energy becomes free for the customer after he breaks even. The savings depend on the electricity tariff in your city. For example, Rs. 10.41/kWh is charged on the top slab in Delhi, so if your bill comes around Rs. 6000, you could save about Rs. 2500 on it. You could infact look up Sunkalp.com’s calculator and feed in your pincode, consumption, and rooftop space, to get an idea of how much you could save. 

Q: Wow, this is pretty interesting! What if I don’t use as much energy as I generate, or I need more at night? What happens then?
Kanika: Most of the systems installed these days, are linked to the grid. So, if you generate more energy, you could reverse meter it back to the grid and earn credits. These credits could be used to take electricity back from the grid when you need it. You will of course, be billed only for the balance.
Q: Is it possible to have a home in India completely running on solar energy?
Kanika: That will still take some time. Solar energy is a good supplement to your existing source, though, since the systems installed these days, offer grid synchronous voltage and frequency. This basically means, that solar systems, these days, connect to the regular electricity grid. So, even though it cannot be the only source of electricity, it can bring down costs significantly, as it costs only about Rs. 4-5/unit.

5 Renovation Ideas to Make a Rented Apartment Look and Feel Like Your Own

Usually, people who intend to put their homes on rent get minimal furnishing done. So when you rent an apartment, you’re likely to find it quite bare. Here are some changes you can make to personalize the space, without too much hassle.

These cosmetic changes along with your classy decorative interior décor items, would certainly give your home that extra edge, and make you feel at home even in a rented apartment.

 

Tips to keep your Home Cool In the Summer Heat

Rooftop Garden

Summer, along with the scorching heat, also leads to higher electricity bills. This is more so, because our homes are not optimized to beat the summer heat. It’s time you prepped up your house before the summer sets in. Here are some ideas to optimize your home for the summer.

Terrace Gardens: If you happen to have a house on the top floor or a bungalow, you’d be grappling with the exposed ceiling getting all heated up. Planting a terrace garden is an excellent way to ensure all the sunlight falling on the terrace gets absorbed and doesn’t heat up the floors below. There are however some measures you need to take before you plan the same. You need to ensure there is a proper drainage system on your terrace, such that the water flows through the appropriate channels; and you need to get layers of waterproofing done, to avoid water seeping through.

Insulated Films on Windows: If you have big windows adorning your house, worry not. You could easily install an insulating film on your windows. These films reflect the sun’s rays and reduce your home’s overall heat gain. As a result, your home feels cooler, and your air conditioner runs less. Insulating films also retain up to 55% of your home’s heat in winter. These films provide comfort you can feel and savings you can see in your utility bills. Insulating films also block out up to 99% of UV (ultraviolet) rays, which we all know are bad for the skin.

Insulated Windows

Reflective Paint: Reflective or insulative paints use a technology where a broad spectrum thermally reflective coating is applied to block heat radiation and to dissipate heat rapidly. This type of paint reduces heat transfer through the coating and reflects back 90% of solar infrared radiation and 85% ultraviolet radiation. This paint should be applied on rooftops, asbestos sheets, exterior walls, and most importantly, roof top water tanks- to avoid water from heating up in the harsh summer.
