Running Dry

Four maps that show how severe India’s water problem is

Fifty four percent of India faces high water stress with groundwater depleting fast – the northwest running dry the fastest.

The Indus river basin has the second most overstressed aquifer – underground layer of water-bearing permeable rock or unconsolidated materials from which groundwater can be extracted – in the world. So says the latest research on the world’s groundwater systems from the University of California, Irvine.  Eight of the aquifers, including the Indus, had no natural replenishment for water usage from them and were classified as ‘overstressed’.

The Indus basin straddles the border between India and Pakistan. The 39% of the basin on the Indian side is the source of water for India breadbasket – Punjab and Haryana. But like other overstressed aquifers around the world, it is impossible to say how much water is left, says the new report that examined 37 of the world’s largest aquifers over the past decade using NASA satellites.

Ground water levels in the rest of India are at similar critical levels. The World Resources Institute’s water risk atlas shows that water stress – the ratio of withdrawal to available supply – across most of Indian subcontinent is medium, high or extremely high.

Earlier this year the institute launched the India Water Tool compiling data from departments like the Central Ground Water Board, the Indian Meteorological Department, the Ministry of Water Resources and the Central Pollution Control Board. Using the tool, they found that more than half of the surface water resources in the country were highly or extremely highly stressed with more than 40% of the available water being used every year. In addition, 54% of wells across the country have depleting water levels.

India’s water ministry found in a study last year that 16% of India’s ground water resources are over exploited. In Delhi, Punjab, Haryana and Rajasthan groundwater extraction is beginning to exceed annual water availability. States like Gujarat, Karnataka and Tamil Nadu are exploiting close to 70% of their ground water reserves. Added to this is the fear that weakening monsoons are failing to replenish the falling water tables.

What’s the difference between ‘a’ washing machine and a ‘great’ washing machine?

The right machine can save water, power consumption, time, energy and your clothes from damage.

In 2010, Han Rosling, a Swedish statistician, convinced a room full of people that the washing machine was the greatest invention of the industrial revolution. In the TED talk delivered by him, he illuminates how the washing machine freed women from doing hours of labour intensive laundry, giving them the time to read books and eventually join the labour force. Rosling’s argument rings true even today as it is difficult to deny the significance of the washing machine in our everyday lives.

For many households, buying a washing machine is a sizable investment. Oddly, buyers underestimate the importance of the decision-making process while buying one and don’t research the purchase as much as they would for a television or refrigerator. Most buyers limit their buying criteria to type, size and price of the washing machine.

Visible technological advancements can be seen all around us, making it fair to expect a lot more from household appliances, especially washing machines. Here are a few features to expect and look out for before investing in a washing machine:

Cover your basics

Do you wash your towels every day? How frequently do you do your laundry? Are you okay with a bit of manual intervention during the wash cycle? These questions will help filter the basic type of washing machine you need. The semi-automatics require manual intervention to move clothes from the washing tub to the drying tub and are priced lower than a fully-automatic. A fully-automatic comes in two types: front load and top load. Front loading machines use less water by rotating the inner drum and using gravity to move the clothes through water.

Size matters

The size or the capacity of the machine is directly proportional to the consumption of electricity. The right machine capacity depends on the daily requirement of the household. For instance, for couples or individuals, a 6kg capacity would be adequate whereas a family of four might need an 8 kg or bigger capacity for their laundry needs. This is an important factor to consider since the wrong decision can consume an unnecessary amount of electricity.

Machine intelligence that helps save time

In situations when time works against you and your laundry, features of a well-designed washing machine can come to rescue. There are programmes for urgent laundry needs that provide clean laundry in a super quick 15 to 30 minutes’ cycle; a time delay feature that can assist you to start the laundry at a desired time etc. Many of these features dispel the notion that longer wash cycles mean cleaner clothes. In fact, some washing machines come with pre-activated wash cycles that offer shortest wash cycles across all programmes without compromising on cleanliness.

The green quotient

Despite the conveniences washing machines offer, many of them also consume a substantial amount of electricity and water. By paying close attention to performance features, it’s possible to find washing machines that use less water and energy. For example, there are machines which can adjust the levels of water used based on the size of the load. The reduced water usage, in turn, helps reduce the usage of electricity. Further, machines that promise a silent, no-vibration wash don’t just reduce noise – they are also more efficient as they are designed to work with less friction, thus reducing the energy consumed.

Customisable washing modes

Crushed dresses, out-of-shape shirts and shrunken sweaters are stuff of laundry nightmares. Most of us would rather take out the time to hand wash our expensive items of clothing rather than trusting the washing machine. To get the dirt out of clothes, washing machines use speed to first agitate the clothes and spin the water out of them, a process that takes a toll on the fabric. Fortunately, advanced machines come equipped with washing modes that control speed and water temperature depending on the fabric. While jeans and towels can endure a high-speed tumble and spin action, delicate fabrics like silk need a gentler wash at low speeds. Some machines also have a monsoon mode. This is an India specific mode that gives clothes a hot rinse and spin to reduce drying time during monsoons. A super clean mode will use hot water to clean the clothes deeply.

Washing machines have come a long way, from a wooden drum powered by motor to high-tech machines that come equipped with automatic washing modes. Bosch washing machines include all the above-mentioned features and provide damage free laundry in an energy efficient way. With 32 different washing modes, Bosch washing machines can create custom wash cycles for different types of laundry, be it lightly soiled linens, or stained woollens. The ActiveWater feature in Bosch washing machines senses the laundry load and optimises the usage of water and electricity. Its EcoSilentDrive motor draws energy from a permanent magnet, thereby saving energy and giving a silent wash. The fear of expensive clothes being wringed to shapelessness in a washing machine is a common one. The video below explains how Bosch’s unique VarioDrumTM technology achieves damage free laundry.
