IAPMO-India

• IAPMO is an 87 year old non-government organization (NGO)and non-profit association serving the industry

• We are devoted to Health and Safety, primarily in thePlumbing and Mechanical fields

• In 2007, IAPMO established IAPMO – India.

• This resulted in the International Association of Plumbing andMechanical Officials (IAPMO) and the Indian PlumbingAssociation (IPA), working together to establish a model codeof plumbing installation and maintenance for all of India.

Green Approach- A MUST today- for Sustainability (better life cycle costs and

higher performance)- better brand visibility-Better Comfort

• What is Green Approach? – Using technologies which aim tosatisfy the water related needs of the community at thelowest cost to society whilst minimizing environmental andsocial impacts

• The green technologies can be described under two broadcategories:

– Water Efficiency

– Innovative Technologies

Water Efficiency• The optimization hierarchy for achieving

water efficiency in a cost-effective mannerinvolves:– Reducing demands : Achieved through implementation

of measures such as a water-efficient landscapingdesign, water efficient fixtures etc.

– Meeting demands efficiently : Achieved throughoptimization of the system design by using measuressuch as Use of high-efficiency drip systems, climatebased controls, such as moisture sensors with watersupply shut-off arrangements , etc.

– Greening the supply of any residual, reduced demand.Focu

Innovative Wastewater Technologies

• Innovative water/ waste technologiesgenerally is a term used for optionssuch as:– Ultra high-efficiency plumbing fixtures;

– Composting toilets and waterless urinals (whichuse no water);

– Foam flush composting toilets (which requireminimal water per use);

– Smart sewers (which include small diameterpressurized sewer systems) to eliminate wetweather infiltration and also allow for controlover loading on sewage treatment plants.

Importance of Plumbing IncreasedAs Buildings/Building Clusters became more complex

Introduction to high-rise buildings– Multistage pumping– Service floors– Large water tanks

Basements extended beyond building line – Need to divert plumbing lines at basement ceiling– Coordination with other agencies

Complex structures– Post tension slabs– Large spans– Concrete walls

10

Importance of Plumbing IncreasedAs Buildings/Building Clusters became more complex

Due to the new Utilities required– High Pressure requirement for some fixtures

– Dual piping– Solar, Central hot water systems– Central cool drinking water system– Landscaping on terraces and parkings– Hydro-pneumatic Systems– Multiple metering– Building Management Systems

11

Importance of Plumbing IncreasedAs Buildings/Building Clusters became more complex

Increase in General awareness – Health Aspects of Plumbing

– Good plumbing ensures public health

– Good plumbing ensures building health

– Mandatory Rainwater Harvesting

– Water and energy conservation

– Eco-friendly designs

Purpose of Codes

• Codes provide the means to reduce risk to acceptable levels.

• Codes protect the health, welfare, and safety of the public in four ways:

Reduce Potential Hazards

Lower Construction

Costs

Standards in Design and

Construction

Contribute to Community Well-Being

IPA- IAPMO Codes and Publications

All codes are the base for Training and Accreditation

WorkshopsBy following the provisions of UPC-I and GPCS-I you

can save 35% or more on water consumption

Training and Accreditation Workshops

• Recognition to International body

• Industry-Institutional interactions

• World class Plumbing & Mechanical HVAC-R education to staff

• Better plumbing ensuring health & safety of public and structures

• Quality plumbing, more productivity, better reputation

• Better mechanical installations ensuring energy conservation, enhanced IAQ, safety of public and structures and reduced maintenance

• Energy efficient installations, increased efficiency and productivity, better reputation

Half of the World’s Population is covered by IAPMO codes and standards

• The Uniform Plumbing Code – India (UPC-I) is the

first ever plumbing code developed by the Indian PlumbingIndustry itself, to achieve its mission – “Better Plumbing forBetter Living”.

• IAPMO-India and the IPA together have published 2008Uniform Plumbing Code – India. It is a model code ofdesign, installation and maintenance of plumbingsystems in India.

UPC-I

- To ensure supply of safe drinking water

- To remove the waste water efficiently

- To minimize the risk of failure through vigilance and

quality assurance

Green Code Supplement Ushers in a New Era

GIVES MUNICIPALITIES ABILITY TO TAKE THE LEAD ON SUSTAINABLE BUILDING INITIATIVES

What it covers

and discovers

Water Efficiency and Conservation

• High efficiency plumbing fittings, fixtures and appliances.

• Water softening equipment

• Occupancy specific provision in restaurants and medical facilities

• Use of sub-meters

By following the provisions of the

2013 GPCS-I:

You can save at least 35% or more on water

consumption by using water efficient products

Genesis• The need for introducing the rating system for water deficient devices is a

recent one in the country and is a result of fast Urban Growth.

• Earlier most of India’s population resided in its villages. At the time of

independence of the Country the Urban Population was only about 10%.

• In Rural India as also in Urban India, the domestic water needs were met

largely from the underground resources.

Alternate Water sourcesRainwater

Water Efficient Products- India (WEP-I)

Plumbing Fixtures considered for

WEP-I Labelling

• WEP-I will seek to;

• Provide credibleinformation on water-efficient products andpractices.

• Raise awareness about theimportance of waterefficiency and recommendwater-efficient products.

• Aid consumers to make aninformed choice of productsthat conserve water.

Water Conserving fixtures and fittings

1. High Efficiency Toilets (HET) – 20% watersavings and more

2. Waterless and Ultra Low Flow Urinals ‐ Over88% water savings

3. Commercial Bathroom Faucets ‐ Over 75%water savings

4. Showerhead Replacements ‐ 50% reduction

Maximum flow rates at fixtures

Maximum Flow Rates and Flush Volumes

Plumbing Fixtures/ Fixture Fittings Maximum Flow Rate

Water Closets 6 Liters per flush

Urinals 4 Liters per flush

Lavatory, Metered Faucet (Public) 1 Liter per use

Lavatory Faucet 8 Liters/min

Sink, Faucet 8 Liters/min

Bidet, Hand – held Spray 8 Liters/min

Shower Head or Hand held Spray 10 Liters/min

Table 4-1, UPC-I

Owner of Residential Structure replaces Standard Water Closet with 3 Star Rater Water Closet =

20 Liters Per Day Saved

Consumers within Region of 1 million dwellings replace water wasting toilets =

20 million Liters of Water Saved Per Day

700,000,000 liters of water saved per year.

Awareness can be THE solution

Factors that contribute to water saving are:• Right assumptions about the population.

• Modern techniques in landscaping, car wash and washingthe paved areas, water treatment and filtration plants.

• Use of raw water, recycled water from car wash etc.,reclaimed water (gray and black water treatment) andrainwater.

• Promoting use of Water Conserving Devices and WaterEfficient Products (WEPI).

• No leaks.

Factors that contribute to energy saving inplumbing are:

• Energy efficient plumbing products such as clothes washers,dish washers, water purifiers.

• Energy efficient water and sewage treatment plants.

• Centralized hot water supply backed by solar hot watersystem.

• Hydro-pneumatic system for water supply, using energyefficient VFD pumps.

Third Party Inspection for Infrastructure Projects

• QCI approved

• Carried out as per the requirements of ISO/IEC 17020:2012.

• Design approval/ in process/ stage wise/ final Installation and

commissioning of Plumbing and Mechanical HVAC-R systems,

installations in infrastructure projects.

Plan of action forWater use efficiency in Urban Sector

• Awareness generation of Best Plumbing Practices

• Popularize Blue Stars

• Product testing and certification by third party agency

• Third Party Inspection of Infrastructure

• Financial subsidy

• Incentives for manufacturers

• Incentives for purchasers on products and water bills

• Appropriate legislation to mandate

• Enforcement by AHJ

Plan of action forWater use efficiency in Urban Sector

The programme may have to berecommendatory in nature during the earlystages; to be made mandatory and enforced bylaw in due course.– All government buildings more than certain built-up area.

– All government or private projects requiring clearances ofMinistry of Environment and Forest (MoEF).

– All projects that opt for LEED, GRIHA or Eco-housingcertification.

– All public toilets, whether government, municipal or private.
