This document discusses the advantages of V-wire rainwater harvesting (RWH) systems compared to conventional RWH systems. V-wire filter screens are more effective at filtering suspended solids from raw water without clogging. They are made from corrosion-resistant stainless steel for a long lifespan. V-wire screens have a very large percentage of open area to allow maximum water flow with minimal head loss. This improves RWH system efficiency over time compared to conventional slotted pipes.

3. What is VEE WIRE Filter Screens?
VEE-Wire Filter Screens are fabricated in
Pipe Form from Wires.
All Welded Wedge Wires Screen is made
from 2 elements - outside V-shape Wire and
inside Longitudinal Rods.
The V-shaped Wire is spirally wrapped on a
cage made of Longitudinal Rods.
The intersecting of shaped wire and rod is
welded through each other by resistance
welding. Due to resistance welding the weld
joined is very strong.

5. KEY DESIGN FEATURES & BENEFITS OF VEE-WIRE
FILTER SCREEN
EFFICIENT & NON-CLOGGING SCREEN
Effectively Filters out maximum
suspended solids from raw water with
non clogging slots for sustained
recharge rate
ANTI CORROSIVE MATERIAL
Made From Stainless Steel And
Suitable for Acid treatment to remove
incrustation, chocking of gravels
which ENSURES LONG LIFE of RWH
bore well
EASY INSTALLATION
SAVES MONEY, TIME & ENERGY.
Customized for small or very large
roof top area
MORE THAN 1 0TIMES EFFECTIVE OPEN
AREA
Compared to any Slotted pipes gives -
MAXIMUM RECHARGE RATE at minimum
frictional head loss which also reduces
incrustation rate
VEE SHAPED SLOTS:
Produces jetting effect to inject
recharge water into the aquifer.
CONTINUOUS SLOTS GIVES
LARGE 100% OPEN AREA

6. VEE-WIRE FILTER SCREEN SYSTEM & CONVENTIONAL FILTER
METHOD
DETAIL CONVENTIONAL DESIGN VEE WIRE FILTER SCREEN
DESIGN
CONTINUOUS SLOTS Slots are scattered SPECIAL Design gives Continuous Slot
Opening across the periphery and length of
screen
NON CLOGGING SLOTS
Highly susceptible to clogging due to
vertically settling impurities in water
and floating matters which reduces
permeability of filter media
V-shape Wire which gives Inwardly Widening
V-shape Slots. This shape does not give space
for any sand particle to get stuck inside the
slot and hence these screens are non clogging
and this keeps the Efficiency of tube well
maintained over number of years.
VERY LARGE % OPEN
AREA
Less Open Area. The Special Design gives Continuous Slot and
hence the % of Open Area for water to enter
is more than 2 times that of conventional
slotted pipes of same size and slot opening.
This allows more water to enter at much
lesser frictional head loss and the efficiency
of tube well is improved appreciably.
