I COVER STORY

A larmingly the water usage per

person is increasing . The main

reason is the increase in the general

awareness about human health, cleanliness

and safety. The water consumption is also

increasing due to high standard of living,

more number of toilets per apartment and

increase in the average size of apartment.

Other reasons are high pressure, high water

consuming water fixtures that are emerging

in the market. Though the cost is high, they

are becoming more and more popular.

In order to make professional practice

responsible, benchmarking in plumbing

should be adopted as an accepted strategy. A

water-efficient labelling system for plumbing

products is one such approach recognised

universally to achieve the objective of water

conservation in domestic use. Not only will

this initiative assist the National Water

Mission of Government ofindia's 20 per cent

efficiency target , but will fall in line with

other successful water labelling schemes from

around the world.

A few years back, Bureau of Energy

Efficiency set path in labelling of energy

efficient products. The energy consuming

products were rested for energy consumption

and conservation, certified and labelled.

A rating system for the energy conserving

products was established. It 'was simple

for common man to understand and soon

became very popular. Huge campaigns on

TV and newspapers, road hoardings, national

level seminars etc. were some means to create

awareness. It's time now to popularise the

blue stars!

More the blue stars, mbre the water

conservation!

Plumbing Codes Uniform Plumbing Code-India

The Uniform Plumbing Code-India

(UPC-I) is a product of the joint effort of

the Indian Plumbing Association (IPA) and

International Association of Plumbing &

Mechanical Officials (IAPMO), with world

headquarters in USA.

The first edition of the Uniform

Plumbing Code (UPC) in North America was

officially adopted by IAPMO in 1945, based

on the recommendations of the committee

comprising of plumbing inspectors, master

GREEN PLUMBING and journeyman plumbers, sanitary and

mechanical engineers, public utility

companies and the plumbing industry. Since

then, over past 80 years, the code has gone

through consensus development, mitigating

the disorder in the industry as a result of

widely divergent plumbing practices and the

use of many different and often conflicting

plumbing codes.

The rapid development of the Indian

construction industry in the past decade

required the plumbing industry to keep

pace with modern plumbing technology.

For this, the codes, standards and practices

required improvements to be comparable tO

international standards. The basic document

A [~ [f UPDATE

for plumbing, which can be considered as

uniform throughout India, is one part in the

National Building Code of the Bureau of

Indian Standards, implementation of which

is voluntary, until adopted by local statutory

bodies.

With intent to incorporate and

implement the latest technology and systems

for the protection of public health and hygiene

and bring uniformity tO the installation of

plumbing works throughout the country,

IPA has ventured into the preparation of a

uniform code, applicable all over India.

The modified UPC-I has kept all basic

principles of the original UPC intact but

edited co suit the Indian laws, conditions

'Piumb-Acharya' Subhash Deshpande talks about the development in plumbing technology and highlights the importance of standardising

plumbing in India and accepted good engineering practices.

The UPC-I has been designed to provide

a lucid, comprehensive technical reference

to the citizens of India for safe plumbing

practices and at the same time allowing

latitude for innovation and introduction of

new technology.

The UPC-I has been prepared by the

Technical Committee comprising of some of

the eminent consultants, project managers,

contractors and manufacturers in the country,

specially formed for this purpose by the IPA.

The UPC-I was first published in 2008 and

it is IPA's intention to revise, update and re­

publish this document at regular intervals

in the I ~: 1 CPC-I is based on

the 2009 version of the Uniform Plumbing

Code.

Green Plumbing Code Supplement-India IAPMO created the 'Committee for

the Awareness and Understanding of a

Sustainable Environment' (CAUSE) and the

Green Technical Committee (GTC). The

GTC was charged with the development

of the IAPMO's Green Plumbing and

Mechanical Code Supplement (GPMCS)

in an effort to fulfil the IAPMO's call for a

reduction in energy and water consumption

in the Uniform Codes.

IPA volunteered to review IAPMO's

Green Plumbing and Mechanical Code

Supplement (GPMCS), modify it to suit

Indian conditions, practices and laws

and adapt it as 'Green Plumbing Code

Supplement-India' (GPCS-I) to the Uniform

Green Plumbing Code Supplement-India is

a supplement to UPC-I and ITM.

Green Plumbing Code Supplement-India

sustainable plumbing systems in maintaining

the high standards for protecting public

Water Efficient Products-India

This publication for Water Efficient Products­

India (WEP-I) is also the result of the joint

effort of the Indian Plumbing Association

(IPA) and the International Association of

Plumbing & Mechanical Officials (IAPMO­

India). The Code references in this publication

are taken from the UPC-I and GPCS-1.

Prior to this, no rating system existed

m India for water efficient products. The

increasing need for defining water efficient

products in India prompted IPA to develop

such a document in collaboration with

IAPMO-India. The use ofWEP-I is intended

to provide uniformity in the performance of

products.

Development of the system WEP-I is a Rating System for Sustainable

Plumbing in India. The 2011 Water

Efficient Products-India (WEP-1) is a

set of recommendations to all those who

are involved in the design, engineering,

manufacturing, selection, installation and

maintenance of water efficient plumbing

products for domestic and commercial

applications in India. On the date of

publication of 2011 WEP-I, the provisions

in this Code are not mandatory. The use

of WEP-I is intended to encourage use of

water efficient products, to incorporate and

implement the latest technology and systems

and provide uniformity in the performance of

products.

Why a rating system for water efficient

products? Fresh water is a precious but finite resource,

conservation of which calls for urgent and

immediate measures. Increasing population,

March 2012 m

·----+-1.3ooo.C...31ooo!!O~V~E......_._R~S~T~OL....JR....~....Y..._ ______ _ _____ ----=---==

high rate of urbanisation and associated

changes in lifestyles, etc. are all contributing

towards rising water demand.

Consumption of water in domestic and

commercial building applications constitutes

a sizeable proportion of the total water

demand. Therefore, there is a need ro look

for opportunities for the conservation of

water within this user group, wherein the

Plumbing fraternity has a significant role to

perform.

The demand on this scarce resource

could be addressed through a two-pronged

approach, namely, usage of high efficiency

plumbing fixtures and low flow faucets and

by usage of alternative sources of water

(other than potable water) fo r applications

such as flushing of water closets and urinals,

landscape irrigation, car wash and makeup

water for air-conditioning. It is imperative

that efficient plumbing design practices and

installation procedures are adopted which

evolve out of robust codes and standards as

well as appropriate scientific principles.

In order ro make professional practice

responsible, benchmarking should be

adopted as an accepted strategy. Water­

efficient labelling system for plumbing

fixtures and fittings is one such approach

recognised universally to achieve the

objective of water, and energy, conservation

in urban domestic and commercial use. This

document delineates the approach for Water

Efficient Products-India (WEP-1).

Rating Systems in other countries: A few countries across the world have already

established standards for labelling and rating

of water efficient plumbing fixtures, fittings

and appliances with supportive legislations

such as Water Efficiency Labelling System

(WELS) in Australia, WarerSense in USA,

Water Efficiency Labelling Scheme (WELS)

in Singapore, ANQIPS labelling system in

Portugal and WaterWise in UK

WEP-1 will seek to:

• Provide credible information on water­

efficient products and practices

• Raise awareness about the importance of

water efficiency and recommend water­

efficient products

Aid consumers to make an informed

choice of products that conserve water.

Plumbing Fixtures considered for labelling Water Closets: Water closets commonly used

in India can be classified into three different

types: European Water Closet, Combination

Water Closet, Asian/Indian Water Closet

(Squatting Pan).

The flushing devices to be used in

combination with the above fixtures could

either be a cistern (coupled or separate) or a

flushometer, commonly known as flush valve

in India.

goal of water conservation, they are not

being discussed here since the rating systems

under consideration are specific ro products

alone. In such situations, since dual water

supply piping is mandatory, devices to

prevent backflow/back-siphonage such as

vacuum breakers may be superfluous. In

the absence of monitoring mechanism from

the authorities on the quality of reclaimed

water, it may be prudent to use dual-flush

flushometers in lieu of cisterns , since the

latter could involve the danger of large

volume of stagnant microbially-infected

In the case of European water closets, water in living spaces.

water efficient toilet suites are designed

with a coupled cistern and integral trap to Shower Heads/Hand-held Showers: Any

of water per flush. However, in the case of than 9.5 litres per minute do not qualifY for

the Asian (Indian) or combination closet, rating.

water reduction is presently dependent on

use of efficient flushing mechanism (cistern

or flushometer).

The pan and the trap need to be designed

appropriately with further research to ensure

efficient functioning with reduced water

volumes per flush.

The rating system for water closets is

based on the volume water used for each

effective flush. Any water closet consuming

more than 6 litres per flush do not qualifY.

Push cocks cannot be accepted as

flushing devices and hence do not qualifY for

ratings since a push cock is no more than an

inline stop cock. Outler of the push cock is

connected direct to a water closer pan. If rhe

water supply system runs dry, back-siphonage

can occur into the water distribution system

contaminating the same. As a preventive

measure, a well designed flushing device

shall have an atmospheric vacuum breaker at

the outlet to qualifY for rating.

It is preferred that the flushing devices

used with the European water closets are

matched units from the same manufacturer.

In the event, combination products of

different manufacturers are to be submitted

for rating, appropriate undertaking of

compatibility shall be produced to the

satisfaction of the certification agency.

Certain projects mandate use of

reclaimed water for flushing of water

closers. Whilst these projects achieve the

Multiple showerheads Multi-jet

showers serving a single user shall not

have a cumulative total flow exceeding the

above flow-rates. (Multi-jet shower units

cumulatively consuming a volume of water

exceeding the limits mentioned in 3.3.1 are not considered as water conserving

installations).

Flow rate of "rain showers" or "massage

showers" shall be as specified for normal

showerheads and therefore no separate rating

system is called for.

Other fixtures: Bath tubs I whirlpools

consume large volume of water per usage and

therefore are not considered recommended

fiXtures in water- conserving installations.

However, if bath tubs are preferred in an

installation, the flow rate of the tub-filler is

irrelevant since the time required to fill the

tub can only be prolonged by use of a low­

flow faucet and therefore not considered in

the rating system.

The water closets and showers

account for 60 per cent of domestic water

consumption and therefore are covered here

in detail. Other fixtures considered for rating

are urinals, faucets (public and private use),

ablution faucets , kitchen sinks, domestic dish

washers and clothes washers.

Remember Flushometers without atmospheric vacuum

breakers shall not qualify for rating.

Automatic flushing cisterns for urinals are

p rohibited and shall not be co nsidered for racing.

Trough urinals and urinals with an invisible seal are prohibited and

will not qualify for racing . A rat ing system for non-water urinals is not

included in chis document due co the apprehensions among plumbing

professionals on the possible adverse effects .

Mult i-jet shower units, rain showers or massage showers cumularively

consuming a volume of water exceeding che lim its specified are not

considered as water conserving installations.

Metered faucets shall be used on lavarory basins (washbasins) in

public toilets. Volume of water in these faucets is pre-sec per usage/cycle.

The ocher faucets (continuous flow) are generally used in residential

installations where flow races are defi ned as liters per minute. Flow-races

mentioned for faucets are not applicable for demal units . It is important

chat handheld ablution spray units are always provided with a backflow

prevention device co qualify for racing.

In case of dish washers and cloches washers more study is required

with respect co variables such as quantity of water used for full/half load,

temperature of water supplied, dishes with or without pre-rinsing, types/

quali ty of cloches being washed and type of detergent used.

Flow-races prescribed are not applicable for emergency showers or

emergency eye-wash stations as high flow races are required co perform

the emergency act. Similarly, a bedpan sink is exempted from the racing

system as its funct ion is to maintain che sanitary condition at che 'di rty

utility area' which may call for higher flow rates.

Other fiXtures, fittings and appliances such as water cooler, water

heater, receptor, floor trap do not have any relevance co the flow rates,

and therefore are exempted from this rating system.

Qualification

Flow races of various fiXtures indicated above are at a working

pressure of 5.5 bar. The maximum and minimum working pressures

recommended by the UPC-I are 5.5 bar and 0.5 bar (installations wi th

flushing cisterns) I 1.0 bar (installations with flush valves) respectively.

Only those plumbing fiXtures, fittings and appliances shall be

considered for the rating system chat meet:

• The minimum requirements as stated in UPC-I and approved by

corresponding Indian Standard or other international standards

• The requirement of labelling on produces/models

Meet the performance requi rement while ensuring safety and

health aspects. For example, while the performance of water closet

and urinal requires that the solids/liquid be flushed through the

trap and clean the bowl; the performance requirements of shower

includes the spray force and coverage.

Implementation

Effective implementation of the WEP-I initiative will require active

participation of all the stakeholders from the plumbing industry

including consultants, contractors and manufacturers apart from the

moniroring agencies designated by the Government.

Appropriate legislation will need co be enacted with guidelines

co be followed by all concerned in the industry. The programme may

have co be recommendatOry in nature during the early stages; co be made

mandarory and enforced by law in due course.

A pproved laboratories for testing will need co be identified co certify

compliance of the products co the guidelines laid down by the government

from time co time.

As technologies evolve across the globe continually, these guidelines

wiJI need co remain dynamic subject co revisions as and when necessary

through an institutional framework for moniroring the effectiveness and

identify need fo r such revisions .

Being the sole represenrative body of all the stakeholders of the Indian

Plumbing Industry, IPA offers to take the lead in chis initiative cowards che task

of creating awareness. IPA's partner- lAPMO, is recognized worldwide as

an approved agency for resting and certification of p lumbing produces

including the "WaterSense" programme of the USA. •
