Monitoring & Measurement
Water and wastewater monitoring that gives you reliable results on discharges, reuse and receiving waters, and reports ready for your permit.
Confidence that discharges and reuse meet permit conditions
Water quality monitoring is the sampling and analysis of water and wastewater — including effluent discharges, treated wastewater for reuse, groundwater and seawater — to determine physical, chemical and biological quality against applicable standards and permit conditions. It combines on-site measurements such as pH, temperature and conductivity with laboratory analysis and validated reporting.
Water is a scarce resource in Saudi Arabia, and the quality of what facilities discharge, reuse or affect is closely regulated. Industrial plants, utilities, hotels, hospitals, food producers and coastal facilities commonly hold environmental permit conditions on effluent quality, treated wastewater reuse or discharges to the sea, and may also need to monitor groundwater beneath their sites. Reliable data depends on representative sampling, correct preservation, timely laboratory analysis and careful review, and errors in any of these steps can lead to misleading results.
Our water quality monitoring service covers effluent and discharge monitoring at outfalls and treatment plant outlets, treated wastewater intended for reuse such as irrigation or process water, groundwater from monitoring wells, and seawater or marine waters near outfalls and intakes where relevant. We measure on-site parameters such as pH, temperature, conductivity, dissolved oxygen and turbidity, collect grab or composite samples, maintain chain of custody and coordinate laboratory analysis for the chemical and microbiological parameters required by your permit or reuse application.
Results are validated and reported against applicable standards and permit limits, with trends over time and clear identification of any exceedances. For treatment plant operators, this data supports process optimisation as well as compliance, highlighting performance changes before they lead to non-compliant discharges. Where water monitoring forms part of a wider permit commitment, it can be integrated into a single environmental monitoring programme with consistent scheduling and reporting across air, soil, noise and water.
You may need this service when:
Sampling at outfalls and treatment plant outlets according to permit conditions, using grab or composite methods with field measurements and flow records.
Monitoring of treated wastewater intended for irrigation, cooling or process reuse, covering the chemical and microbiological parameters relevant to the intended use.
Sampling from monitoring wells with water level measurement, purging and field parameter stabilisation, to track groundwater quality beneath and around the site.
Sampling of coastal and marine waters near outfalls and intakes where relevant, to assess the effect of discharges on receiving waters.
Field measurement of pH, temperature, conductivity, dissolved oxygen and turbidity, with sample preservation, chain of custody and laboratory analysis coordination.
Validated results compared with applicable standards and permit limits, with trend analysis, exceedance identification and recommended follow-up actions.
We review permit conditions, reuse requirements, treatment processes and existing data to define sampling points and parameters.
We set sampling locations, methods, frequency, preservation and laboratory analysis, and agree the schedule with your operations team.
We collect samples, measure on-site parameters with calibrated instruments and record conditions, flow and any operational observations.
We dispatch samples under chain of custody within holding times and follow up analysis with an appropriate laboratory.
We review laboratory and field results for completeness and consistency and compare them with standards, limits and earlier data.
We issue compliance reports, flag exceedances promptly and discuss causes and corrective options with your team.

Requirements vary by activity, location and permit conditions. We confirm the applicable requirements for your project at the start of every engagement.
Parameters are set by your permit and the type of facility. Effluent monitoring commonly includes pH, temperature, suspended solids, biochemical and chemical oxygen demand, oil and grease, nutrients, metals and microbiological indicators, with additional parameters for specific industrial processes. We review your permit and processes to confirm the list, so analysis covers what is required without unnecessary cost.
A grab sample is collected at a single moment and shows quality at that time. A composite sample combines several portions collected over a period, often in proportion to flow, and represents average quality. Permits sometimes specify which type is required for each parameter. Where they do not, we select the approach that most accurately represents your discharge and its variability.
Yes. We monitor treated wastewater intended for irrigation, landscaping, cooling or process use, covering the chemical and microbiological parameters relevant to that use and to the applicable requirements. Results are reported so you can show that the water meets the conditions for its intended reuse and can track treatment performance over time.
We coordinate analysis with an appropriate laboratory selected for the parameters and methods required, and manage sample preservation, chain of custody and holding times. We review the laboratory reports and validate the data before reporting. Where your permit or the authority specifies requirements for the laboratory, we confirm them at the planning stage so the selection meets them.
We flag the result promptly, check field and laboratory records for sampling or analytical issues and, where appropriate, recommend confirmatory sampling. We then help your team identify likely causes, such as treatment upsets, process changes or flow variations, and document corrective actions. The report records the exceedance and the response clearly for any regulatory follow-up.
Design and delivery of multi-media environmental monitoring programmes: sampling plans, field work, laboratory coordination, data QA/QC and periodic compliance reports.
Key benefit: Defensible environmental data that keeps permit reporting on track
Construction and operating permits, renewals and modifications — from permit strategy and document preparation to submission and responses to authority comments.
Key benefit: Fewer resubmissions and a clearer path to permit decisions
Ongoing compliance management: obligation registers, inspection readiness, responses to regulatory notices and violations, and corrective action plans that close gaps.
Key benefit: Lower exposure to violations and operational disruption
Waste classification, audits, waste management plans, segregation and storage, transporter and receiver checks, and documentation for MWAN compliance.
Key benefit: Compliant waste handling with a clear, traceable chain of custody
