Water Management

Water Efficiency Audits and Feasibility Studies

We begin with a detailed assessment of how, where, and when water is used across your site. Our audits uncover inefficiencies and identify actionable opportunities to reduce consumption, improve performance, and lower costs. This includes both operational recommendations and strategic input to support Environmental Management Systems (EMS) and ISO 14001 compliance.
 
In addition, we assess the technical and economic feasibility of alternative water sources, including:

 
• Rainwater harvesting
• Greywater reuse
• Process water recycling

 
These studies are tailored to your site and operations, helping you unlock long-term savings, gain planning advantages, or benefit from potential permit exemptions.

Leak Detection Auditing

Undetected leaks are a major source of unnecessary cost and resource loss. We use non-invasive methods-such as acoustic and thermal detection-to locate and quantify leaks within buildings, infrastructure and underground networks. By demonstrating proactive maintenance, clients can also improve their standing with regulators and insurers.

Water Flow & Mass Balance Analysis

Accurate data is fundamental to water management. We provide temporary or permanent flow monitoring using non-invasive ultrasonic sensors to build a full picture of water movement and usage patterns. This data supports everything from performance benchmarking to permit applications and system optimisation. For regulated sites—particularly those operating under Environmental Permitting Regulations (EPR)—we develop detailed water mass balances to track inflows, outflows, losses, and storage. These models support permit applications, audits, and internal resource accountability frameworks.

Meter Accuracy Verification

Inaccurate meters can lead to significant billing errors and non-compliance with reporting requirements. Our team conducts independent meter verification to confirm accuracy, detect faults, and ensure reliable data for operational decision-making and regulatory reporting.

Tariff Optimisation Assessments

Water billing is often based on assumptions, estimates, or legacy infrastructure. We review your current billing structure and identify opportunities to reduce charges, including:

 
• Right-sizing of meters
• Consolidation of supply points
• Qualification for trade effluent or non-return allowances

These assessments frequently deliver quick wins with tangible cost savings.

Implementation & System Upgrades

We don’t just advise—we deliver. Arthian can support the specification, procurement and installation of engineered systems, such as:

 
• Water-saving devices
• Leak repair programmes
• Flow control solutions
• Smart metering systems

All upgrades are delivered with a focus on operational continuity, ROI, and regulatory alignment.

SuDS & Domestic Wastewater Solutions

Water management doesn’t end with supply—it includes effective drainage and treatment. Arthian designs and optimises Sustainable Urban Drainage Systems (SuDS) and domestic sewage treatment systems to support:

 
• Planning and development approvals
• Surface water management
• Pollution prevention and environmental compliance

Our team understands the regulatory frameworks and engineering requirements necessary to design effective systems for both urban and rural sites.
