Outfall Monitoring Systems
Accurate Wastewater Monitoring for Environmental Compliance
AllWater Technologies supplies robust outfall monitoring systems designed to meet the increasing demands of environmental compliance across the UK’s industrial and commercial sectors. With tighter discharge consents issued by the Environment Agency and other regulatory bodies, real-time and reliable wastewater monitoring is no longer optional – it’s essential.
Our systems are engineered to measure key discharge parameters such as flow, pH, temperature, and turbidity. Suitable for both treated and untreated effluent, these monitoring packages help businesses maintain transparency, prevent pollution, and protect against costly penalties.
What Is Outfall Monitoring?
Outfall monitoring refers to the continuous or periodic measurement of water quality parameters at the point where treated or untreated water is discharged into the environment, typically into rivers, lakes, sewers, or soakaways. This is a key requirement under ‘consent to discharge’ licences issued by the Environment Agency.
Outfall monitoring systems provide real-time insight into what is leaving your site, ensuring your business stays compliant with discharge limits and can demonstrate active environmental responsibility.

Our support includes

Telephone & remote diagnostics for rapid fault identification

System troubleshooting and root cause analysis

Planned service visits tailored to your production schedule

Guidance on optimisation, upgrades and retrofit options

Ongoing training and user support post-installation

On-site engineering support from qualified specialists

Typical Outfall Monitoring Parameters
Our outfall monitoring systems can be configured to measure one or more of the following:
- Flow rate (volumetric or velocity-based)
- pH
- Temperature
- Turbidity or suspended solids
- Conductivity or total dissolved solids (TDS)
- Ammonia and nitrate levels (optional)
Readings are logged for auditing purposes and can be viewed locally or remotely via digital interfaces. Our systems integrate easily with existing plant equipment, PLCs, or SCADA platforms.
V-Notch Tanks for Wastewater Monitoring
Many of our systems are supplied with V-notch tanks, which enable precise and cost-effective measurement of flow and water quality at the point of discharge.
V-Notch Tank Features:
- Open-top design for easy access and visual inspection
- Precision-engineered weirs for accurate flow monitoring
- Integrated mounting points for sensors and probes
- Durable materials (polypropylene or stainless steel)
- Custom sizes available for specific flow profiles
These tanks allow for safe sampling and calibration, providing a clear and consistent data source that simplifies reporting and compliance tasks.
Compliance Monitoring Systems
We provide integrated compliance monitoring systems that ensure your outfall meets required discharge conditions under permits such as:
- Environment Agency ‘Consent to Discharge’
- Trade Effluent Agreements
- IPPC and COMAH regulations
- Site-specific environmental risk assessments
Each system is designed to provide:
- Real-time alerts if parameters exceed thresholds
- Data logging for historical reporting and audit trails
- User interfaces for on-site and remote access
- Calibration and verification protocols to maintain data integrity
Whether you need a standalone monitoring point or integration into a wider treatment and control system, AllWater can design and supply a tailored solution.
Industrial Discharge Monitoring Applications
Our industrial discharge monitoring systems are suitable for a wide range of sites and sectors, including:
- Food and beverage production
- Pharmaceutical and life sciences
- Chemical manufacturing
- Surface treatment and plating facilities
- Energy and utility providers
- Landfill leachate management
- Construction and tunnelling discharge control
We ensure that systems are built to suit site-specific challenges, including irregular discharge patterns, difficult access, or the need for ATEX-rated instrumentation.
