Distribution Pipe
It is recommended that Water Utilities providing protected drinking water, to use HD/MD PE-80 and PE-100 grade pipes conforming to ISO 4427/1996 to make the system totally leak-proof and corrosion resistance. It is a well-known fact that the soil in which the pipes are buried, are of corrosive nature, which triggers outside corrosion of the conventional pipes. Added to this, the leakage of electricity from the underground cables as well as spillage of chemicals and contamination of subsoil with leaky sewerage and drainage pipelines add to the galvanic and chemical corrosion of conventional pipes. Dissolved oxygen and chlorine in the treated water accelerate the inside corrosion.
JAIN HD/MD Polyethylene PE-80 grade pipes conforming to ISO 4427 as well as IS 4984 are available up to 1200mm Diameter in all pressure classes as per the standard. Installation of these pipes is easy and the joints are butt-welded joints, which are stronger than the pipe. Tapping for the house service connection is also made very easy with tapping tees and saddles and is totally leak-proof.
Total distribution and house service connection with JAIN HD/MD polyethylene piping system is not only the way to provide the society with safe drinking water but also to save precious drinking water from UFW.

Safe Drinking Water
Drinking water is an essential commodity to the society, being supplied to all sections of the society, which includes healthy, aged and sick. The importance of safe drinking water is vital and the quality of water must not be compromised in the short or the long term. The quality of water does not just mean the toxicity of contaminants and their direct impact on health, but also includes the way in which the consumer gets the water.
Influence of Materials
The influence of materials and substances in contact with drinking water should not be underestimated. Leaching of soluble compounds can produce a direct effect on the taste, turbidity and colour of the water. Many materials can support the growth of microorganisms, which can cause deterioration in the microbiological quality of the water. Metabolic products produced as a result of microbial growth can cause bad tastes and the development of slimes and flakes of microbial growth are also capable of producing bad tastes and odours. In some cases, the physical degradation of a product in service can occur as a result of microorganism growth.
Selection of Material for Pipe
The pipe material selected for conveying & distributing potable water should ensure the following essential norms in a water supply system
- It should not give taste to water.
- It should not change the appearance of the water.
- It should not allow growth of microorganisms in the water in contact with the materials or on the surface of the material.
- It should not release substances in to the water that may be concern to public health.
- It should not release any material in to the water.
- These conditions are in accordance with BS 6920 - Leaching tests for nonmetallic products for use in contact with potable water.
- Jain Irrigation Systems Limited, the company which produces Thermoplastic water supply pipelines, has taken it upon itself to have their PE pipes and fittings, which are supplied for potable water supply, successfully tested by WRc-NSF Ltd., of UK in accordance with BS 6920.
Comparisin of Jain PE Home-Line pipe with the Conventional GI pipe
Jain PE Home - Line Pipe |
GI House Service Pipe |
- Life Cycle Analysis (LCA) shows PE is totally eco-friendly by its low energy consumption both in process of production and usage.
|
- LCA shows that GI is not eco-friendly as it consumes more energy in the process of production and usage.
|
- The jointing is easy. No threading tools-spanners required.
|
- The jointing requires special tool kit for installation.
|
- The joints are rubber sealed and corrosion proof.
|
- The joints get corroded and start contamination of water.
|
- The system has very smooth bore and hence more flow with less head.
|
- The system has rough bore and gets more pitted and rough due to corrosion and affects free flow.
|
- Due to air tight rubber seal joints, root ingress is totally avoided.
|
- Due to corroded joints, the joints become leaky and allow root ingress which leads to choking.
|
- Due to flexibility and long length, avoids use of extra fitting to take contours at the site.
|
- Due to its rigidity, lots of fittings have to be used to take the contours at the site.
|
- Very tough and inert material. Hence there is no damage during digging of trenches.
|
- Gets damaged easily in aggressive soil conditions due to chemical corrosion.
|
- Totally prevents sub soil water entering the system which safe guards potability of water conveyed.
|
- Due to leaky joints, the potability of water is contaminated by subsoil water entering the system.
|
- The system installation is easy due the compression type joints and saves time in installation.
|
- Takes lot of time to install and holds up Water Supply and installation.
|
- The system is cost effective.
