Method — Assumption-based estimate

Points per system is a declared reference assumption. It sizes the T&C effort and instrument hire; it is not a specification or a commissioning schedule.

Every result below is produced by the same engineering engine that feeds the High-Rise reference project, so a quantity taken from this page and a quantity taken from the workflow cannot disagree.

Governing Formula

Governing Formula
N_points = n_systems x n_points_per_system

Where:

  • n = Number of systems

Derived Equations:

Commissioning duration: d_comm = n_systems x days_per_system
Instrument fleet: N_instr = n_systems x instr_per_system

Assumptions & Limitations

  • No witness/hold-point schedule, no ITP and no manufacturer-specific requirement list.
  • Assumes parallel resourcing across systems; sequential working extends the programme.
Engineering Disclaimer & Verification Notice

This calculator provides preliminary engineering estimates for informational and planning purposes. Actual reverse osmosis / engineering system performance depends on site conditions, feed-water chemistry, membrane characteristics, operating pressure, temperature, recovery limits, fouling/scaling potential, and system design. Verify results using project-specific data, manufacturer projections, and applicable engineering standards before final design or operation.
