The need for sustainability in building design has never been more critical, as both environmental and economic factors drive the need for resource efficiency. In the construction and maintenance of non-domestic buildings, water consumption and leak detection are essential areas of focus. BREEAM (Building Research Establishment Environmental Assessment Method) provides internationally recognized standards to help measure and improve the environmental impact of these buildings.
Two crucial aspects of water management under BREEAM are WAT 02 and WAT 03, which emphasize water consumption monitoring and water leak detection. For developers, consultants, and project managers, understanding these requirements is key to ensuring compliance and advancing sustainability. This blog explores what BREEAM WAT 02 and WAT 03 entail and how S&S Northern’s Merlin WDP system can help meet these stringent standards.
BREEAM WAT 02: Water Consumption Monitoring
WAT 02 focuses on the efficient use of water in non-domestic buildings by requiring monitoring systems that can track water consumption. The goal is to encourage reduced water usage, helping both the environment and building owners through cost savings.
Key Requirements of WAT 02:
- Monitoring of water consumption for all major water uses, including toilets, urinals, taps, and any systems requiring significant water usage.
- Data collection and review, with an emphasis on identifying excessive water use or patterns that suggest potential leaks or inefficiencies.
- Installation of a Building Management System (BMS) or similar tools to monitor and control water use over time.
By providing real-time data, WAT 02 helps building operators respond to inefficiencies swiftly, driving improvements in water management.
BREEAM WAT 03: Major Water Leak Detection
WAT 03 specifically addresses water leak detection, requiring systems that can quickly identify and react to major water leaks. The purpose is to minimize water wastage and the potential for costly damage to buildings and infrastructure.
Key Requirements of WAT 03:
- Installation of automatic water leak detection systems that cover all relevant water systems within a building, including supply pipes between buildings and the main water meter.
- The leak detection system must alert building managers in real-time, allowing immediate action to be taken in case of a leak.
- Where feasible, the system should be connected to the Building Management System (BMS) to enable automated shutoff or response measures.
BREEAM awards points under WAT 03 for the effective design and integration of leak detection systems, contributing to overall building sustainability.
The Importance of Water Management in Non-Domestic Buildings
Water is a precious resource, and its efficient use is a cornerstone of sustainable building design. In non-domestic buildings, such as offices, schools, hospitals, and industrial units, water wastage can lead to significant financial and environmental costs.
Implementing BREEAM WAT 02 and WAT 03 standards is crucial for several reasons:
- Environmental Impact: Conserving water reduces the strain on local water supplies and minimizes the environmental impact of unnecessary consumption.
- Financial Savings: Inefficient water use can be a significant expense. By monitoring water consumption and addressing leaks promptly, building operators can save on water bills and maintenance costs.
- BREEAM Certification: Buildings that achieve high BREEAM scores benefit from increased property value, reduced operating costs, and enhanced appeal to environmentally-conscious tenants or buyers.
By adhering to WAT 02 and WAT 03, developers and building managers contribute to a building’s overall sustainability while ensuring compliance with international best practices.
How the Merlin WDP System Helps Achieve Compliance with BREEAM WAT 03.
S&S Northern’s Merlin WDP system is an advanced water leak detection product that is perfectly aligned with BREEAM’s WAT 02 and WAT 03 standards. Designed to monitor and detect leaks in various types of non-domestic buildings, the Merlin WDP system offers the following features to help projects meet these critical requirements:
Key Features of the Merlin WDP System:
- Comprehensive Monitoring: The Merlin WDP system monitors water flow in the building’s main supply line and distribution systems through pulsed water meters, helping to track water consumption in real-time. This functionality directly supports BREEAM WAT 03 by providing the necessary data to assess water usage patterns and detect inefficiencies.
- Automatic Leak Detection: The Merlin WDP system includes an automatic shutoff mechanism that activates when a major water leak is detected, helping to prevent significant water damage and wastage. This feature aligns with BREEAM WAT 03 by enabling building managers to respond quickly to leaks.
- Integration with BMS: The Merlin WDP system can be integrated with a Building Management System (BMS), allowing for centralized control and real-time alerts. This integration is critical for both WAT 02 and WAT 03 compliance, as it enables building operators to manage water consumption and leak detection through a single, streamlined interface.
- Customizable Alerts: The system offers customizable alerts for different levels of water usage and leaks, ensuring that building operators are immediately notified of any issues that need attention. This proactive approach minimizes water wastage and ensures that any potential issues are addressed promptly.
- Compliance Assurance: By installing the Merlin WDP system, developers and building managers can be confident that they are meeting the water management requirements set out by BREEAM, helping them achieve higher certification scores and enhance the building’s sustainability profile.

How the Merlin PIR Sensors & GoldSeal Water Solenoid Valves Helps Achieve Compliance with BREEAM WAT 02.
S&S Northern’s Merlin PIR sensors, when integrated with GoldSeal water solenoid valves, provide an efficient water management system that aligns seamlessly with BREEAM WAT 02 standards. Designed to control water flow based on occupancy in WCs and bathrooms, this innovative solution ensures water is used only when necessary, reducing consumption and waste in non-domestic buildings.
Key Features of the Merlin PIR Sensor and GoldSeal Solenoid Valve System:
- Occupancy-Based Water Control: The Merlin PIR sensors detect motion in WCs and bathrooms, activating the GoldSeal water solenoid valves only when the space is occupied. This precise control directly supports BREEAM WAT 02 by ensuring water is supplied only when required, reducing unnecessary water use.
- Automatic Shutoff: When the area is unoccupied, the water supply is automatically shut off, preventing water wastage. This feature contributes to more efficient water management, a key goal of BREEAM WAT 02, by minimizing water consumption during non-peak times.
- Compliance Assurance: By incorporating Merlin PIR sensors and GoldSeal solenoid valves into building designs, developers and managers can confidently meet the BREEAM WAT 02 requirements. This ensures that water consumption is monitored, controlled, and minimized, contributing to higher BREEAM certification scores and a more sustainable building profile.
