OPTIMIZATION OF WATER SUPPLY
1.Network Management
a)
Optimum Design limit and estimations
b)
Reduce System Losses
c)
Optimize Storage Tank Capacities
d)
Reduce Pumping System or booster
stations
PIPES MATERIAL SELECTION..
Glass Reinforced Pipes has a “C”-value of 150 and stronger than steel
pipes but yet of non-corrosive material.
OPTIMIZATION OF WATER SUPPLY
2. Energy Management
a)
Improve Power/Voltage Quality
b)
Select Best Switching Gears
c)
Retrofit with Energy-saving devices e.g
VSD, Controller etc
d)
Select Best Efficient Motors & Pumps
e)
Reduce System Losses
OPTIMIZATION OF WATER SUPPLY
3. Environmental & Resources
Management
a)
Retrofit with environmental-friendly devices e.g lownoise devices.
b)
Select Best Design Suitability e.g less sludge
treatment, non chemical WTP
c)
Select Construction Plan with Low Impact on
Environmental e.g No Dams Plan, using Natural Substorage Reservoirs
d)
Improve On Raw Water e.g siltation dam,
Use of Riverbank Filtration System(RBF) &
Horizontal Collector Well method(HCW)
Introduction to Groundwater
a. Simple and cheap to treat to good drinking
water
b. Stable quality and quantity all year
c. Localized availability, means decentralized
infrastructure and short transmission costs
d. Far better protection than surface water
e. Little impact on nature and environment
Horizontal Collector Well System :
a groundwater engineering application
Refers to the one of the
groundwater system
being abstracted from
aquifers in the alluvium
such as sand and gravel
layer through radial wells
which are drilled and
installed horizontally
inside concrete caisson.
RIVERBANK FILTRATION SYSTEM (RBF) WITH
HORIZONTAL COLLECTOR WELL (HCW)
RIVER
Groundwater aquifer
RIVERBANK FILTRATION SYSTEM
CONSTRUCTION OF HORIZONTAL COLLECTOR WELL
ESSENTIAL BENEFIT OF HORIZONTAL COLLECTOR WELL
IN RIVER INFILTRATION SYSTEM
1. LARGE QUANTITIES OF WATER PRODUCED OVER SMALL
CONSTRUCTION AREA
2. LOW IN CONSTRUCTION COST , LESS TIME TO CONSTRUCT
AND IT’S GREEN TECHNOLOGY.
3. MAINTENANCE IS EASY AND ECONOMICAL WITH COST
SAVING
4. PRODUCED WATER IS CLEAR AND PURE (LOW TURBIDITY)
AND PROTECTED FROM OUTSIDE THREATS.
5. MINERAL CONTENT (IRON & MANGANESE) OF WATER IS LOW
6. WATER PRODUCTION IS GUARANTEED, ESPECIALLY DURING
DRY SEASONS
Riverbank Filtration System – Advantages
3 Aspects of Reduction:
REDUCTION ON COSTS
-Operational Cost
- Energy Cost
COSTS
- Maintenance Cost
REDUCTION ON RISKS
- Quality of Water
RISKS
- Failure on Operation
- Environmental Damages
REDUCTION ON THREATS
- Climate Change Impact
- Pollution of River
- ‘War’ on Use of Water

Energy Efficient & Costs Savings
1. Energy Costs reduced– + High Eff.Pumps & VSD
2. Maintenance is minimised – Excavators, Pumps
3. Filter operation is optimized – less backwash
4. Very Little Sludge – no sludge management
5. Optimization of WTP Whole Operation
Energy savings up to 45% with the RBF effect and VSD usage.

in non-conventional treatment processes.
Subterranean Iron Removal System – biochemical
reaction in aquifer to treat groundwater in primary
processes and without the use of chemicals.
