CUSTOM. PROJECT-SPECIFIC. GLOBAL SUPPLY.
Custom Perforated Pipes for Monitoring & Dewatering
GEOLUR supplies project-specific perforated and slotted PVC, PVC-U and PE/HDPE pipe systems for monitoring wells, standpipes, recharge wells, pumping wells and dewatering projects worldwide.
Product Overview
Custom Perforated Pipes for Project-Specific Groundwater Applications
GEOLUR supplies custom perforated and slotted engineering pipes for groundwater monitoring, water standpipes, open standpipe piezometers, recharge wells, pumping wells, relief wells and dewatering systems. Material, dimensions, perforation geometry, screened interval and connection method are reviewed against the project requirement rather than treated as a one-size-fits-all catalogue item.
Materials
PVC, PVC-U, PE or HDPE, subject to project environment, specification and supply availability.
Perforation
Slots, round holes and project-specific patterns can be reviewed by opening size, spacing, rows and screened interval.
Configuration
Plain riser and perforated/screened sections can be combined to suit the intended well function.
Applications
Monitoring, recharge, pumping, relief and construction dewatering applications, subject to engineering design.
Documentation
Drawings, QA/QC requirements, datasheets and packing requirements should be stated in the RFQ.
Global Supply
GEOLUR, operated by GeoOrigin Engineering Limited, supports project-specific engineering pipe sourcing worldwide.
Applications
Where Custom Perforated Pipes Are Used
The same pipe can perform very different functions depending on its screened interval, opening geometry, filter arrangement and hydraulic objective.
Water Standpipes
Plain riser and perforated sections for groundwater-level access within a defined monitoring zone.
Open Standpipe Piezometers
A screened intake section works with the surrounding filter zone to allow groundwater communication with the standpipe.
Groundwater Monitoring Wells
Perforated or slotted pipe defines the interval through which groundwater enters the well for observation or sampling.
Recharge & Relief Wells
Opening pattern and screened length must be coordinated with recharge/relief objectives and formation conditions.
Pumping Wells
Pipe diameter, screen geometry, mechanical capacity and pump arrangement should be reviewed together.
Dewatering Wells
Custom perforated PVC/PVC-U or PE/HDPE pipe may be considered for selected construction dewatering and groundwater drawdown systems.
Customisation
What Can Be Customised?
Exact manufacturing capability is confirmed during quotation. The project RFQ should define the parameters that control installation and groundwater performance.
Material & Diameter
Material, OD/ID and wall configuration are reviewed against project requirements and available supply ranges.
Pipe & Screen Length
Module length, plain-riser length and the perforated/screened interval can be defined by project drawing.
Slot Geometry
Slot width, length, orientation, rows and spacing should be coordinated with formation/filter-pack and hydraulic objectives.
Round-Hole Pattern
Hole diameter, number of rows, circumferential spacing and staggered patterns can be specified where feasible.
Connection Method
Threaded, coupled, welded or other project-specific connections are confirmed according to material and supply configuration.
Accessories
Caps, couplings and other compatible accessories can be reviewed when included in the RFQ.
| Configuration | Typical Characteristic | Engineering Consideration |
|---|---|---|
| Slotted Pipe | Controlled narrow openings in a defined screen zone. | Slot width, spacing, open area and filter-pack/formation relationship. |
| Round-Hole Pipe | Discrete holes arranged by diameter, rows and spacing. | Hole size and density affect both hydraulic opening and remaining pipe-wall area. |
| Custom / Mixed Pattern | Different opening patterns or zones along one pipe system. | Requires clear drawings, dimensions, tolerances and QA/QC criteria. |
Selection Guide
How to Specify a Custom Perforated Pipe
Application
Monitoring, recharge, pumping, relief, dewatering or drainage.
Environment
Groundwater chemistry, salinity, contamination context and temperature where relevant.
Geometry
Depth, borehole size, pipe diameter, riser length and screened interval.
Filtration
Formation gradation, filter pack and particle-retention objective.
Hydraulic Duty
Monitoring response, inflow, pumping or recharge objective.
Mechanical requirements
Connection and installation
Perforation drawing
| Factor | PVC / PVC-U | PE / HDPE |
|---|---|---|
| General behaviour | Relatively rigid thermoplastic pipe suitable for many well and monitoring configurations. | More flexible thermoplastic pipe with high impact tolerance and broad engineering use. |
| Typical use | Monitoring wells, standpipes, selected recharge, pumping and dewatering installations. | Selected dewatering, recharge, environmental and coastal/corrosive applications. |
| Key review | Depth, pressure, joint loading, groundwater chemistry and monitoring objectives. | Flexibility, connection, handling, chemistry, temperature and sampling compatibility where relevant. |
Engineering Considerations
Perforation, Filter Pack, Flow and Mechanical Capacity
A screened pipe should not be specified in isolation from the material surrounding it. Opening geometry, formation particle distribution, filter pack, well-development method and hydraulic response work together as a system.
Filter-Pack Relationship
Screen opening should be selected in relation to the formation and filter-pack design rather than by a universal slot size.
Open Area & Flow
More opening area can improve hydraulic access, but it also removes pipe-wall material and can affect mechanical capacity.
Clogging & Sediment
Overly small openings can increase plugging risk; overly large openings may allow excessive sediment movement.
Depth & External Pressure
Deep installations require verification of pipe-wall, collapse, joint and handling requirements.
Material Compatibility
Actual groundwater chemistry, temperature and project duration should be reviewed before making a material claim.
Know the Limit
For very high-capacity production wells, a purpose-designed continuous-slot or other specialist well screen may be preferable to simple perforated pipe.
Supply Process & QA/QC
From RFQ to Project-Specific Supply
Send Requirements
Share drawings, dimensions, application, quantity and destination.
Technical Review
GEOLUR checks material, perforation, connection and documentation requirements.

Engineering References for Monitoring-Well and Well-Screen Design
These references support the principle that screen openings, filter packs, material selection and well construction are engineering-design variables rather than universal product settings. They do not imply GEOLUR product certification unless the order documents explicitly state it.
