This document provides information on Vee-wire filter screens used for rainwater harvesting and borewell applications. Vee-wire screens have continuous slots that provide over 2x the open area of conventional slotted pipes, preventing clogging. They are made of stainless steel through a welding process and come in various diameters and slot sizes. Vee-wire screens provide a more efficient alternative to traditional gravel filtration systems by eliminating maintenance costs and space requirements while allowing easy cleaning and sustained recharge rates.

5. THE FILTER SCREENS ARE MADE FROM
V-SHAPED WIRE FOR MAXIMUM
EFFICIENCY
The out side wire is wrapped around
cage of support rods & fusion-welded
at each intersection.
WHAT IS VEE-WIRE SCREEN
TECHNOLOGY

6.  Unlike Slotted Strainers, it is not made by simply putting
Slots on a Blind Pipe. Instead, it is Manufactured by A Very
Special, Fully Computerized Process.
 A Continuous Profile Wire is Spirally Wound around Series
Of Longitudinal Support Rods.
 Each and Every Intersection of Profile Wire and Rod is
Fusion Welded on Computerized Machine to Impart High
Strength.
 The Spacing between Two Adjacent Turns Of Profile Wire is
the Slot Or Opening for Water to Enter.
 The Profile of the Wire is such that its Flat Surface remains
on the Outside Dia. of Screen to produce Inwardly
Widening Slots.
 This Way we get a Strong Screen (Due To Continuous Wire
and Fusion Welding) with Continuous Slot of Inwardly
Widening Shape.

CYLINDRICAL
SCREENS
Welding at Each Intersection of
Rod & Wire
VEE-Wire 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.

8. KEY DESIGN FEATURES OF VEE-WIRE
FILTER SCREEN
Made from Stainless Steel and suitable for acid treatment to remove
incrustation, chocking of gravels which ensures long life of bore well.
Produces jetting effect to inject recharge water into the aquifer.
 The V-shaped wire produce non clogging type slots.
 The slots are widening inside (inflow directions) due to this design no
sand particles get any way to stick in the slot.
 This contributes to well efficiency & consistent output for number of
years.
8
 More than 2 times effective open area (compared to any slotted
pipes) gives maximum recharge rate at minimum frictional head loss
which also reduces incrustation rate.
 The manufacturing process gives CONTINUOUS SLOTS across the
periphery of screen which gives more open area than any type of
slotted pipes or punched pipe.
 More open area helps to reduce entry velocity & resulting to more
entry of water with reduce head loss and pumping head.

9. WIDE RANGE OF SLOT
 V-wire Filter Screens are available in wide slot range.
 This helps to select the proper slot as per sand particles size.
 The slot are available from 0.15 mm to 3 mm slot.

ISO 9001:2000 as well as with Bureau of Indian Standards.

13. COMPARISON BETWEEN
VEE-WIRE FILTER SCREEN KIT SYSTEM & CONVENTIONAL FILTER METHOD
 Non clogging due to which efficiency of borewell
is not reduced over number of years.
 Zero Maintenance required and hence very Cost
effective.
 Raw water enters horizontally into the
screen assembly and it begins from the bottom
of the pit hence all the impurities will be settled
at bottom first. Due to above phenomena pit will
remain open from the top and recharge process
will be continued more than the Conventional
System.
 Highly susceptible to clogging due to vertically
settling impurities in water and floating matters
which reduces permeability of filter media.
 Cleaning procedure is time consuming,
laborious and very Costly.
 As the top layer gets chocked, the rate of
percolation of water to the borewell will go down
rapidly.

VEE-WIRE FILTER SCREEN DESIGN
CONVENTIONAL
DESIGN
CONTINUOUS SLOTS
 SPECIAL Design gives Continuous Slot Opening across
the periphery and length of screen. Slots are scattered
NON CLOGGING
SLOTS
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.
Highly susceptible to clogging
due to vertically settling
impurities in water andfloating
matters which reduces
permeability of filter media
VERY LARGE % 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.
Less Open Area.
BETTER SAND
FILTRATION
Due to specialized manufacturing process, wide range
of slot opening is available down to 0.15 mm to allow
proper slot selection depending upon the size of sand
in particular area. This gives better sand control and
reduced pump maintenance and longer bore well life.
Precise slot selection is not
possible depending on the size of
sand in particular area.

CLEANING & MAINTENANCE
Cleaning Maintenance is Very Easy
and Fast.
Total layers of gravel and sand to
be removed and may be required
frequently during the time of
maintenance.
Cleaning procedure is time
consuming, laborious and costly.
Very difficult to maintain during
the season.
SUSTENANCE OF RECHARGE
PROCESS
Raw water enters horizontally into
the screen assembly and it begins
from the bottom of the pit hence all
the impurities will be settled at
bottom first.
Due to above phenomena, pit will
remain open from the top and
recharge process will be continued
more than the conventional system.
As the top layer gets choked, the
rate of percolation of water to the
well will go down rapidly.
EASY MONITORING &
TRANSPARENCY OF FILTER PIT
The operating condition of the filter
pit can be easily monitored so that
suitable precautions can be taken if
necessary.
Once the pit is filled with gravels
and other media, it will not be
possible to visualize the working
process so no advance actions can
be taken to rectify.
