5. WATER SUPPLY SYSTEM:
1) Over Head Tank or Up Feed System:
2) Hydro pneumatic System:
Type of pipe Material:
A) Galvanised Iron Pipes - metal pipe:
B) Mild Steel Pipes metal pipe:
C) Poly Vinyl Chloride pipes - non- metal pipe:
D) High Density Poly Ethylene Pipes - non metal
pipe:
E) Ductile Iron Pipes:

6. Mild Steel Pipes:
Number of joints are less as they are available in longer length.
Pipes are durable and can resist high internal water pressure
and highly suitable for long distance high pressure piping.
Flexible to lay in certain curves.
Light weight and easy to transport. Damage in transportation is
minimal.
Pipes are prone to rust and require higher maintenance.
Require more time for repairs and not very suitable for
distribution piping.
Available in diameter of 150-250 mm for water supply and cut
lengths of 4 - 7 m (2.6-4.5 mm wall thickness).
Steel Pipes are joined with flanged joints or welding.

7. Galvanised Iron (GI) Pipes:
Cheap in cost and light in weight.
Light in weight and easy to join.
Affected by acidic or alkaline water.
GI pipes are highly suitable for distribution system.
They are available in light (yellow colour code), medium (blue
colour code) and heavy grades (red colour code) depending on
the thickness of pipe used. Normally, medium grade pipes (wall
thickness 2.6-4.8 mm) are used for water supply system.
Normally, 15-150 mm size pipes (nominal internal diameter) are
used for distribution system. They are available in length of 3 m.
GI pipes can be used in non-corrosive water with pH value
greater than 6.5.
GI pipes can be used for rising main as well as distribution.
GI pipes are normally joined with lead putty on threaded end.

8. Poly Vinyl Chloride (PVC unplasticised) Pipes:
Cheap in cost and light in weight.
Economical in laying and jointing.
They are rigid pipes.
Highly durable and suitable for distribution network.
Free from corrosion and tough against chemical attack.
Good electric insulation.
Highly suitable for distribution piping and branch pipes.
Less resistance to heat and direct exposure to sun. Hence, not
very suitable for piping above the ground.
PVC pipes weigh only 1/5th of steel pipes of same diameter.
Certain types of low quality plastic impart taste to water.
 Available in size 20-315 mm (nominal internal diameter) for
water supply with pressure class of 2.5, 4, 6, 8 & 10 kg/cm2 for
water supply. Ideally pipes with 6 kg/cm2 should be used.

9. HDPE Pipes:
Light in weight. • Flexible than PVC pipes.
HDPE pipes are black in colour.
Suitable for underground piping and can withstand movement of
heavy traffic.
Allows free flowing of water.
Highly durable and suitable for distribution network.
Free from corrosion.
Good electric insulation.
Useful for water conveyance as they do not constitute toxic
hazard and does not support microbial growth.
Normally, 20-315 mm diameter pipes are used for water supply
and distribution system with pressure ranging from 6-10 kg/cm2 .
Available in coils in small diameters. Above 110 mm diameter,
available in lengths starting from 6 m.

10. Ductile Iron Pipes:
Ductile Iron pipes are better version of cast iron pipes with
better tensile strength.
DI pipes are prepared using centrifugal cast process.
DI pipes have high impact resistance, high wear and tear
resistance, high tensile strength, ductility and good internal
and external corrosion resistance.
DI pipes are provided with cement mortar lining on inside surface which
provides smooth surface and is suitable for providing chemical and physical
barriers to water. Such pipes reduce water contamination.
The outer coating of such pipes is done with bituminous or Zinc paint.
DI pressure pipes are available in range from 80-1000 mm diameter in lengths
from 5.5-6 m.
Available in thickness class K7 and K9 with barrel wall thickness ranging from
5- 13.5 mm. Also available in pressure class (Like C25, C30, C40 etc.).
They are about 30 percent lighter than conventional cast iron pipes.
DI pipes lower pumping cost due to lower frictional resistance.

11. Over Head Tank or Up Feed System: (Indirect supply system)

When the water pressure in mains is not sufficient for direct water supply
system from mains can be either pumped up in to the over head storage
tank, usually at the roof of the building from where the water is supplied to
different floors by gravity or stored into the underground storage tank from
where is pump to the OHT. & then it is supplied by gravity.

12. Pressurized Distribution System (Hydro-pneumatic Pumping
System):
Variation of direct pumping system.
Air tight pressure vessel is installed on line to regulate the operation of
the pumps.
The pressure switch installed in the pressure vessel/ tank switches off after
reaching the predetermined pressure and the operating pump is put to
stop.
Air compressor is necessary to feed the water with air to maintain the air
water ratio.
This system eliminates the need of an OHT and supplies water at a much
higher pressure resulting the even distribution of water on all floors.
Pressurized distribution system is a direct pumping system incorporating a
recharge diaphragm vessel.

13. Pressurized Distribution System (Hydro-pneumatic Pumping
System):

14. Combined Distribution System:
In this system, a combination of gravity
and pressurized distribution is adopted.
A few upper floors are provided with a
pressure booster pumping system to
achieve the desired residual pressure,
while the lower floors are fed by gravity
supply.
Water collected in the over head tank is
distributed to the various parts of the
building. To achieve required residual
pressure for top 2 to 4 floors for proper
functioning of the fixtures, a pressure
booster pumping system is installed
on the dedicated outlet from overhead
tank with its own distribution piping
serving the top 2 to 4 floors. For lower
floors, water is distributed by gravity
system.

15. Sewerage Treatment Plant (STP):
MBBR TECHONOLOGY (Moving bed biofilm reactor):
The MBBR system consists of an aeration tank (similar to an activated sludge
tank) with special plastic carriers called fluidized aerated bed (FAB) media that
provide a surface where a biofilm can grow. The carriers are made of a material
with a density close to the density of water (1g/cm7). An example is high density
polyethylene (HDPE) which has a density close to 0.95 g/cm7. The carriers will
be mixed in the tank by the aeration system and thus will have good contact
between the substrate in the influent wastewater and the biomass on the
carriers. To prevent the plastic carriers from escaping the aeration it is
necessary to have a sieve on the outlet of the tank.
Advantages The MBBR system is considered a biofilm process. Other
conventional biofilm processes for wastewater treatment are called trickling
filter, rotating biological contactor (RBC) and biological aerated filter (BAF).
Biofilm processes in general require less space than activated sludge systems
because the biomass is more concentrated, and the efficiency of the system is
less dependent on the final sludge separation. A disadvantage with other biofilm
processes is that they experience bio-clogging and build-up of head loss.
MBBR systems don't need a recycling of the sludge, which is the case with
activated sludge systems. The MBBR system is often installed as a retrofit of
existing activated sludge tanks to increase the capacity of the existing system.
