OPTIMIZATION OF WATER SUPPLY1.Network Management2.Energy Management3.Environmental & ResourceManagement

OPTIMIZATION OF WATER SUPPLY1.Network Managementa) Optimum Design limit and estimationsb) Reduce System Lossesc) Optimize Storage Tank Capacitiesd) Reduce Pumping System or boosterstations

PIPES MATERIAL SELECTION..Glass Reinforced Pipes has a “C”-value of 150 and stronger than steelpipes but yet of non-corrosive material.

OPTIMIZATION OF WATER SUPPLY2. Energy Managementa) Improve Power/Voltage Qualityb) Select Best Switching Gearsc) Retrofit with Energy-saving devices e.gVSD, Controller etcd) Select Best Efficient Motors & Pumpse) Reduce System Losses

OPTIMIZATION OF WATER SUPPLY3. Environmental & ResourcesManagementa) Retrofit with environmental-friendly devices e.g lownoisedevices.b) Select Best Design Suitability e.g less sludgetreatment, non chemical WTPc) Select Construction Plan with Low Impact onEnvironmental e.g No Dams Plan, using Natural SubstorageReservoirsd) Improve On Raw Water e.g siltation dam,Use of Riverbank Filtration System(RBF) &Horizontal Collector Well method(HCW)

Introduction to Groundwatera. Simple and cheap to treat to good drinkingwaterb. Stable quality and quantity all yearc. Localized availability, means decentralizedinfrastructure and short transmission costsd. Far better protection than surface watere. Little impact on nature and environment

Horizontal Collector Well System :a groundwater engineering applicationRefers to the one of thegroundwater systembeing abstracted fromaquifers in the alluviumsuch as sand and gravellayer through radial wellswhich are drilled andinstalled horizontallyinside concrete caisson.

RIVERBANK FILTRATION SYSTEM

CONSTRUCTION OF HORIZONTAL COLLECTOR WELL

ESSENTIAL BENEFIT OF HORIZONTAL COLLECTOR WELLIN RIVER INFILTRATION SYSTEM1. LARGE QUANTITIES OF WATER PRODUCED OVER SMALLCONSTRUCTION AREA2. LOW IN CONSTRUCTION COST , LESS TIME TO CONSTRUCTAND IT’S GREEN TECHNOLOGY.3. MAINTENANCE IS EASY AND ECONOMICAL WITH COSTSAVING4. PRODUCED WATER IS CLEAR AND PURE (LOW TURBIDITY)AND PROTECTED FROM OUTSIDE THREATS.5. MINERAL CONTENT (IRON & MANGANESE) OF WATER IS LOW6. WATER PRODUCTION IS GUARANTEED, ESPECIALLY DURINGDRY SEASONS
