A Good Beginning – Need to Accelerate
Context :
Water purifiers must mention wastage, efficiency rating: / Eco Times / 12 Oct 2021
Extract :
Manufacturers of reverse osmosis-based water purifiers will now have to rate their appliances on efficiency and water wastage, while water supply agencies will have to declare the total dissolved solids (TDS) in the water being supplied, according to officials.
The environment ministry has notified regulations for water purification systems which will come into effect 18 months from now.
The new 'Regulation on Use of Water Purification System (WPS)' mandate that each water purifier will now come with a ' conformance label '--a star rating like label—declaring its efficiency level as well as water-rejection / wastage levels
The Bureau of Indian Standards is learnt to have developed IS standard (IS 16240: 2015) for drinking water purifying systems which will be technology specific and also detail ,
# the acceptable quality of the purified water, besides
# the recovery efficiency of the machine.
At present, purification machines have around 20% water recover efficiency as they are estimated to reject/waste near 70-80% of the water taken in for purification.
The environment ministry--as custodian of green resources--has been pitching for bringing in a more water efficient system in a phased manner, starting with 40-60% efficiency level to reduce wastage.
The RO manufacturer will now have to obtain standard mark/certification under a licence from the BIS on the water purification system.
==============================
MY TAKE :
Ø IS standard (IS 16240: 2015) does NOT stipulate the maximum amount of electricity that such Water Purifying Systems may consume per litre of water purified .
Ø Bureau of Energy Efficiency , under its section “ Standards & Labelling “ does NOT even list “ Water Purifiers “ as a domestic appliance needing standardization
Ø Considering our long-term CLIMATE CONTROL GOALS, it is very important to come up with Energy Efficiency Standard Inputs - EESI - ( max units of electricity that each domestic appliance may consume per unit of OUTPUT ) for each and every appliance / gadgets / device / lamps etc., that consume electric power
Ø Such EESI need to be laid down for different MODELS ( sizes ) of each device
Ø It should be made MANDATORY for all manufacturers to print this EESI Certificate on the devices
HOW WILL THIS HELP WITH LOWERING OF POWER CONSUMPTION ?
Ø Within next 3 years, all households will replace their DUMB electric meters with SMART meters
Ø I envisage that the Second Generation of Smart Meters will not only measure the total electricity consumption of the entire household but they will be able to measure / record / transmit ( over internet ), INDIVIDUAL power consumption of each and every appliance / device / lamp etc ., which draws its power through the Smart Meter
Ø Such measurement of power consumption ( INPUTS ) of INDIVIDUAL devices and comparison against their RATINGS ( OUTPUTS ) , will enable computation of their ENERGY USAGE EFFICIENCY – and the CARBON CREDITS / DEBITS earned by each device

Carbon Finance through Carbon Credits ………………….[ 12 Mar 2021 ]
Dear Shri Abhay Bakreji
( Director General – Bureau of Energy Efficiency / dg-bee@nic.in ),
I am not aware of such an CARBON CREDIT ECO-SYSTEM , existing in any country
But then, considering the POWER SHORTAGE CRISIS ( - and the ever-rising prices of diesel / petrol ) over the past few weeks, our need for creating such an Eco-System, is , both URGENT and IMPORTANT
Fortunately, implementation of none of my above-mentioned suggestions need any Rocket Science
This is a matter of National Interest and does not need any APPROVAL / GREEN SIGNAL from Union Cabinet – although it will go a long way for expeditious implementation !
Any initiative in this respect by BEE, will be highly appreciated by all concerned
With regard,
