A water supply system is an engineered network that collects, treats, stores, and distributes water to consumers, meeting their needs for drinking, sanitation, and other uses. It encompasses various components like sources, treatment plants, storage facilities, and distribution networks. The primary goal is to deliver potable water in sufficient quantity and at adequate pressure to meet the demands of residential, commercial, industrial, and public needs, including fire protection.

3. • source, treatment, storage, and distribution
components.
• These components work together to deliver
potable water to consumers. The source (e.g.,
rivers, lakes, aquifers) provides raw water,
which is then treated to remove impurities.
• Treated water is stored in reservoirs or tanks
before being distributed through pipes to
homes and businesses.

4. Objective of water supply system
• To deliver safe wholesome water to the consumer
with quality, quantity, pressure, and at low cost.
• To make water available within easy reach of
consumers.
• To make adequate provisions for emergencies like
fire fighting, festivals, meetings, etc.
• To reduce environmental pollution and
unemployment.
• To protect from water born disease.
• To improve the economic condition of the locality
and maintain better sanitation.

5. 1. Water Source:
• Surface Water: Rivers, lakes, and reservoirs
are common surface water sources.
• Groundwater: Wells and springs tap into
underground water reserves.

6. 2. Treatment:
• Intake Structures: Facilities to withdraw water
from the source (e.g., dams, pumps).
• Treatment Plants: Processes to remove
contaminants like bacteria, sediments, and
chemicals. This may involve filtration,
disinfection (e.g., chlorination), and other
methods.

7. Treatment
• Screening
• Aeration
• Flocculation
• Sedimentation
• Filtration
• Disinfection

8. 3. Storage:
• Reservoirs: Large-scale storage facilities (e.g.,
dams, elevated tanks) to maintain a consistent
water supply.
• Tanks: Smaller storage units, often used for
balancing supply and demand.

9. Storage reservoir
• Storage Reservoir
• Flood control Reservoir
• Multipurpose Reservoir
• Distribution Reservoir
• Surface Reservoir
• Elevated Reservoir

10. 4. Distribution:
• Pumping Stations: Power the water through the distribution
network, especially when elevation changes require it.
• Transmission Mains: Large-diameter pipes that carry water from
treatment plants to storage and distribution areas.
• Distribution Networks: A system of interconnected pipes (mains,
sub-mains, and service lines) that deliver water to individual
properties.
• Valves: Control water flow and pressure within the system.
• Fire Hydrants: Provide a readily available water source for
firefighting.
• Service Connections: Individual connections to homes and
businesses.
