6 THE FLOOD

7 HOW TO MANAGE Physical Means Sociological Means Economics Means Network Management Energy Management Environmental & Resource Management

8 OPTIMIZATION OF WATER SUPPLY 1.Network Management 2.Energy Management 3.Environmental & Resource Management

9 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

10 PIPES MATERIAL SELECTION.. Glass Reinforced Pipes has a C -value of 150 and stronger than steel pipes but yet of non-corrosive material.

11 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

12

13 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)

14 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

15 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.

16 RIVERBANK FILTRATION SYSTEM (RBF) WITH HORIZONTAL COLLECTOR WELL (HCW) RIVER Groundwater aquifer

17 RIVERBANK FILTRATION SYSTEM

18 CONSTRUCTION OF HORIZONTAL COLLECTOR WELL

19 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

20 Riverbank Filtration System Advantages REDUCTION ON COSTS -Operational Cost - Energy Cost - Maintenance Cost 3 Aspects of Reduction: COSTS REDUCTION ON RISKS - Quality of Water - Failure on Operation - Environmental Damages REDUCTION ON THREATS - Climate Change Impact - Pollution of River - War on Use of Water RISKS THREATS

24 24 JELI WTP

25 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

26 Energy savings up to 45% with the RBF effect and VSD usage.
