Direct project answers
What project teams need to know about Elevated & Gravity Water Systems.
What projects are suitable for elevated and gravity water systems?
Typical project pathways include development infrastructure, remote communities, schools and health facilities, and international community water projects. Final suitability depends on the exact configuration, site conditions, operating requirements and destination.
What information is needed to specify elevated and gravity water systems?
Before specification or quotation, the project review should confirm: Verified product specifications or documented product facts; Clear applications, limitations and configuration boundaries; Project inputs required for manual quotation or technical review; Apollo supply-only scope and purchaser/local-project responsibilities. Claims are kept tied to the exact proposed system rather than transferred from a related product or reference configuration.
Can Apollo NZ Global supply elevated and gravity water systems internationally?
Apollo can supply suitable projects internationally where the product and destination pathway are current. Send the project location, intended use, dimensions or quantities, timing, relevant drawings or photographs, and any known performance, compliance or environmental requirements for review.

Selection factors
Define these before equipment is fixed.
Required pressure
Tank elevation
Highest and lowest delivery points
Pipe losses
Tank structural support
Wind and seismic criteria
Overflow and drainage
Fill-pump duty
Specification controls
Keep the public pathway useful without turning planning data into guarantees.
Tank elevation does not guarantee acceptable pressure at every outlet.
Support structures and foundations require project-specific structural design.
Excess pressure at low points may require zoning or pressure control.
Safe access, overflow, drainage and maintenance need to be included in the elevated-storage design.
Working resources
Carry this section through design, procurement and handover.
Source-Water Review
Structure source, testing, seasonal reliability and treatment questions before equipment is selected.
Open reviewDemand & Storage Planner
Turn demand and storage autonomy into a transparent planning range.
Open plannerSpecification Template
Use one controlled schedule for storage, treatment, pumping, controls and project interfaces.
Open templateResponsibility Matrix
Separate supplied equipment from civil works, pipework, power, approvals and operations.
Open matrixInstallation & Commissioning
Plan site readiness, assembly, cleaning, testing and water-quality verification.
Open commissioningOperations & Maintenance
Define routine checks, consumables, spares, alarms and operator ownership.
Open O&MProject note
Gravity systems can reduce energy dependence, but the available static head, pipe losses, terrain and structural support must be checked as one hydraulic and structural design.
Final equipment, material, capacity, certification, drawings, performance and commercial scope are confirmed against the exact project configuration.
