Licensed Water & Energy Engineering

Engineering rigor for the pumps that move water and the energy behind them.

Independent Israeli engineer, licensed by the Ministry of Energy, with 15+ years of current field practice. Working with water utilities, industrial plants, and consulting firms on pump efficiency testing, energy audits, and continuous monitoring.
Expertise

Four practice areas

Built around measurement, standards, and evidence — not marketing claims.

ISO 9906 pump testing

Grade 2 field testing with synchronized flow, head, and electrical power measurement. Wire-to-water efficiency with uncertainty propagation, manufacturer-curve comparison, and recommended corrective actions.

Regulatory energy audits

Multi-year energy surveys under Israel's Ministry of Energy framework. Consumer mapping, NPV / IRR / payback economics, conformance reporting, and accompaniment through regulatory review.

Continuous pump monitoring

SCADA / PLC / energy-meter integration for 24/7 efficiency and degradation tracking. Read-only, water-grade security. Engineering intelligence over existing telemetry — not a rip-and-replace.

Pump selection engineering

Duty-point analysis, multi-pump station optimization, life-cycle cost modelling, VFD and NPSH assessment, and professional datasheets for procurement decisions.

Outsourced energy officer

Acting as your external licensed energy officer: monthly consumption tracking, anomaly flagging, regulatory correspondence, and deadline management for organizations above the statutory threshold.

Documentation & reports

Reports built to withstand regulator review and technical scrutiny — clear methodology, traceable measurements, reproducible calculations. Deliverables ship as PDF, Word, and structured data.

Why pump efficiency matters at a system level

In municipal water systems, pumping typically accounts for the majority of electricity consumption. Pump impellers wear, bearings drift, operating points shift away from best efficiency, and losses accumulate quietly across a fleet. In many water utilities, a measurable share of the energy bill is recoverable through testing, corrective maintenance, variable-speed control, and operational changes — none of which requires new capital-intensive infrastructure.

The work is unglamorous. Instruments are calibrated, data is collected in the field under real conditions, numbers are compared against the applicable standard, and findings are documented clearly enough that an operator, a regulator, or an insurer can follow the reasoning. The methodology doesn't change when you change the logo on the cover page.

Who we work with

Engagement types

Water utilities & associations

Periodic ISO 9906 testing across pump fleets, baseline efficiency reporting, and continuous-monitoring integration. Appropriate for groundwater, booster, and reclaimed-water installations.

  • Fleet efficiency baseline & retest schedules
  • Degradation modelling and maintenance triggers
  • SCADA & energy-meter integration

Industrial facilities

Regulatory energy audits, process-pump efficiency assessments, and tariff / variable-speed optimization for plants that cross the Ministry's controlled-body consumption threshold.

  • Consumer mapping and load profiling
  • NPV / IRR / payback economics per recommendation
  • Compliance submission and regulator accompaniment

Engineering & consulting firms

Specialist sub-consultancy on pump-efficiency work inside larger engagements. Confidential, white-labelable reports; direct engineer-to-engineer communication without account-manager layers.

  • ISO 9906 field testing as a subcontracted deliverable
  • Technical review of existing audit reports
  • Expert opinion for procurement and due diligence

Equipment manufacturers & OEMs

Independent third-party performance verification, warranty-dispute technical analysis, and calibration of field test protocols against factory curves.

  • Independent site-acceptance testing
  • Warranty and performance-dispute analysis
  • Field-protocol alignment with test-stand data
Approach

How engagements typically unfold

01

Scoping call

Short conversation by email or video to understand the asset, the standard, and the constraints.

02

Written proposal

Method, instrumentation, deliverables, timeline, and fee — in writing, no hidden line items.

03

Field & analysis

Calibrated instruments, synchronized measurements, documented uncertainties, and traceable calculations.

04

Report & follow-up

Clear deliverable, plain-language recommendations, and availability for technical questions after delivery.

About

Yehuda Buju

Practice

Independent water and energy engineer based in Israel. Licensed by the Israeli Ministry of Energy to perform energy surveys, and working day-to-day as a senior engineer inside a regional water association — which means the reports you receive are written by someone who also operates this equipment in the field.

The practice is deliberately small. Every engagement is handled directly by the named engineer, from the first email through instrument calibration to the final signed deliverable. That constraint is a feature, not a limitation.

Qualifications

B.Sc Water Industries Engineering (Kinneret Academic College)
M.Sc Energy Engineering (Afeka College of Engineering)
Licensed energy surveyor — Israeli Ministry of Energy
Senior engineer — regional water association
15+ years of current engineering practice
ISO 9906 pump testing methodology — day-to-day working discipline

Inquiries from outside Israel

If you are an engineering firm, utility, OEM, or consultant working on pump-efficiency or energy-audit engagements and would like to discuss a possible collaboration, the right first step is a short email describing the asset and the question.
