SYSTEM OVERVIEW

How VODA works, who it serves, who we are.

STEP 01
COLLECT
Rainwater intercepted from existing roof downpipes via the VODA tapping collar — no new infrastructure required.
STEP 02
FILTER
VODA self-cleansing filter removes debris and contaminants — no manual cleaning, no servicing interval.
STEP 03
STORE
Filtered rainwater held in modular VODA tanks, sized to the structural, spatial, and access constraints of each site.
STEP 04
DISTRIBUTE
Stored rainwater delivered to non-potable end uses — WC flushing, landscape irrigation, general washing.
Fully gravity-driven at base configuration — no electricity, no pump, no energy cost.
Who we serve
  • Commercial shopping centres & retail
  • Corporate headquarters & offices
  • Industrial facilities & plants
  • Government & institutional buildings
  • Large-scale & mixed-use developments
What we do
  • Reduce mains water use & utility cost
  • Meet LEED, GBI & RWH compliance

Integration into an active, high-visibility corporate environment
System Design
Storage
VODA Cylinder modular tank configuration
Layout
Designed around available plant-room space and access requirements
Operations
Installed without disruption to daily building operations

CASE STUDY 03 · INDUSTRIAL · SITE-CONSTRAINED

WASCO — Wall-Mounted Solution

When plant-room space and aesthetics ruled out ground-standing tanks entirely.

Project Context
Client
Industrial facility
Application
Rainwater harvesting for non-potable reuse
Challenge
Plant-room constraints + aesthetic and spatial requirements ruled out ground-standing VODA Cylinder tanks entirely
System Design
Solution
VODA 1 wall-mounted units throughout the facility — no Cylinder used
Trade-off
Higher unit cost per litre of storage vs. cylinder configuration — acknowledged and accepted by client
Install
Adapted to available wall surfaces and structural fixing points across the facility
Outcome
  • Fully gravity-driven RWHS achieved despite site constraints — zero pump, zero electricity
  • Gravity-first performance maintained regardless of tank format
  • GMH engineers around site realities — VODA Cylinder is the standard, wall-mounted is fully viable where constraints demand it

A PRACTICAL ENTRY POINT TO RAINWATER HARVESTING

Phase 1 Starter Package

A defined, fixed-price rainwater harvesting starter — a proven, measurable starting point before committing to a fully engineered solution. Not for residential use. Final pricing fixed once site is confirmed.

OPTION A
Gravity-Fed System
ZERO PUMP · ZERO ELECTRICITY
RM29,600

Pure gravity configuration. The default specification where site geometry permits — lowest operating cost over the life of the system.

OPTION B
Pump-Assisted System
WHERE GEOMETRY REQUIRES LIFT
RM31,400

Gravity-first design with integrated pump where roof catchment and storage geometry require assisted delivery to end-use points.

Controlled Cost

Fixed scope, fixed pricing — no open-ended commitment.

Measurable Returns

IoT flow meters track actual harvest from day one.

Path to Expansion

Clear next step once Phase 1 performance is established.

From Interest to Installation

Site investigation & next steps

Two variables that determine final ROI
VAR 01
Verified roof catchment area — actual usable area confirmed on site.
VAR 02
Number of users / pax consumption — actual daily demand established.
What the site check confirms
  • RWDP locations — existing downpipe positions and tapping points
  • Tank placement — optimal positioning within available footprint
  • Gravity vs. pump — determines Option A or Option B
  • Usage points — WC connections, garden taps, irrigation outlets
  • Pipe routing — most efficient path from catchment to storage to distribution
  • Additional works — any scope beyond standard package allowance quoted separately
Post-handover: 6-month performance monitoring

GMH monitors system performance for the first 6 months after handover, using IoT flow-meter data.

Any anomalies are identified and resolved within the monitoring period.

Client receives performance data to support sustainability reporting from month one.

NEXT STEP

Phase 1 is a practical, low-risk way to start rainwater harvesting — fixed pricing, defined scope, measurable savings, and a clear path for future expansion. The next step is a site visit — no obligation, no cost, no guesswork.

YOUR SYSTEM. YOUR NUMBERS. YOUR SITE.

We don't sell from a catalogue.
We derive a system from your numbers.

  • Your system is sized to your actual demand — not over-engineered, not under-built.
  • Every ringgit in the budget is justified by a corresponding ringgit in water savings over the agreed payback period.
  • Mains water remains connected as silent automatic backup — your supply is never at risk.
  • After payback, water savings become pure financial return — the system continues long after it has paid for itself.
