Whether your firm has been selected to fulfil a design and build project, or you’re carrying out building, civil engineering, or engineering construction work on a small project where you’ll undertake to complete all the work, or you’re working on a larger more complex project and subcontracting, working with suppliers who understand the pressures you’re facing will help you to meet your key performance objectives and avoid unnecessary liquidated and ascertained damages (LADs).
Founded in 1985, Watersavers specialises in the design and manufacture of flow rate and pressure monitoring water leak detection solutions, PIR controls & solenoid valves, legionella prevention solutions and urinal controls.
Watersavers designed the very first, award winning, water-saving infrared urinal flushing control and we continue to develop products that reduce water consumption and unnecessary leaks.
Being part of Daro Group, we benefit from decades of long-established British design and engineering capability and the wider support of the Group’s central resources such as strategic planning, marketing, sales, financial management, leadership and on-going investment.
We pride ourselves on being agile and responsive. Embracing continuous improvement, we are trusted by the range of customers we serve, providing excellence as standard.
If you need to work with a knowledgeable specialist supplier to help you save more than water, that you can trust, please contact us email@example.com or call 01603 720999.
Benefit from BREEAM credits
Working with contractors to achieve BREEAM credits Watersavers products are a perfect fit for BREEAM Wat 02 assessment criteria for the monitoring and management of water encouraging reductions in water consumption and BREEAM wat 03 assessment to reduce the impact of water leaks that may otherwise go undetected.
The growing awareness in the value and potential scarcity of water means that demands are growing for preventative solutions to address unnecessary water leaks that not only result in environmental damage due to loss of water and the associated cost, but also the cost of the catastrophic impact of damage to buildings, electronic equipment, data, the building occupiers’ reputational damage and inconvenience, particularly where buildings are occupied by multiple companies.
Working with contractors we understand the exacting key performance objectives and the pressure to achieve them, either directly or through managing your subcontractors.
We can provide you with specialist help when your performance objectives include:
- Ensure minimum risk of Legionella growth
- Ensure no dead legs
- Review and incorporate design features which contribute to BREEAM credits to achieve the level of BREEAM compliance
- Supply and install a leak detection system and an automatic shut-off system and link the system to an integral alarm
Ensure minimum risk of Legionella growth
Legionella is a genus of pathogenic gram-negative bacteria that causes legionellosis including Legionnaires’ disease and Pontiac fever. The bacteria develop in favourable conditions such as in water without any flow, that consequently becomes dull and sluggish in the pipe, and the bacteria multiply by binary fission at temperatures between 20 and 50 degrees* Celsius.
Legionellosis is a collective term for diseases caused by legionella bacteria that live in small drops of water and moist conditions which are usually associated with water systems and pipes. They may also be found in purpose-built water systems such as cooling towers, evaporative condensers, hot and cold-water systems and spa pools.
When ingested the bacteria causes a pneumonia-type illness, Legionnaires’ disease, which can result in respiratory failure, and milder flu-like illness, Pontiac fever and Lochgoilhead fever. It is important to carry out legionella water testing on a regular basis.
The most effective, non-chemical, and kinder to the environment, treatments to prevent Legionella include:
- Flush water pipes to reduce or remove instances of stagnation
- Maintain cold water temperatures below 20 degrees Celsius and hot water above 50 degrees Celsius
- Monitoring scale and sediment in the water
Water testing and maintenance of water systems is an effective prevention of Legionella. This can be easily and cost effectively achieved by installing a time discharge valve, to flush pipes, or perform a controlled discharge of water above a preset temperature to lower the water temperature to a safe level.
Ensure no dead legs
Dead legs are rarely found in a modern single dwelling, however, in a refurbishment or a commercial building where further development is planned, dead legs may need to be intentionally installed. Such as, when your project has piping that requires capping at one end to facilitate future expansion.
On the other hand, functional dead legs may occur from lack of use, as happens during student holidays in educational buildings such as schools, colleges and universities or in areas of low occupancy in hotels and hospitals or wings of buildings during development or refurbishment for example, at an airport. Dead legs can also unintentionally occur following a change of use or occupancy.
Additionally, you can install a solenoid shut off valves (as close to the main water pipe as possible) to cut off the water to the potential dead leg, ensuring there is no water present and, therefore, the water system is safe.
The Contractor shall review and incorporate design features within the domestic water services design which contribute to BREEAM credits which the Contractor is targeting to achieve the level of BREEAM compliance stipulated within the Contract documents
In our experience these usually include:
- Water Monitoring
- Water leak detection and prevention
Watersavers’ products apply to Wat 02 and Wat 03 monitoring and management of water and water leak detection and prevention, which have a collective total of three credits available.
BREEAM Wat 02 Assessment Criteria – One Credit – Water Monitoring
BREEAM Aim – To ensure water consumption can be monitored and managed and therefore encourage reductions in water consumption.
The following is required to demonstrate compliance for one credit:
- The specification of a water meter on the mains water supply to each building; this includes instances where water is supplied via a borehole or other private source.
- Water-consuming plant or building areas, consuming 10% or more of the building’s total water demand, are either fitted with sub meters or have water monitoring equipment integral to the plant or area (see Compliance notes).
- Each meter (main and sub) has a pulsed output to enable connection to a Building Management System (BMS) for the monitoring of water consumption.
- If the site on which the building is located has an existing BMS, managed by the same occupier/owner (as the new building), the pulsed water meter(s) for the new building must be connected to the existing BMS.
The contractor to supply and install a leak detection system and an automatic shut-off system to ensure no further water is delivered where indicated on the drawings and described in the scope of works. Link the system to an integral alarm system or BMS if installed.
BREEAM Wat 03 Assessment Criteria – Two Credits (in two parts) – Leak Detection and Prevention
BREEAM Aim – To reduce the impact of water leaks that may otherwise go undetected.
The following is required to demonstrate compliance for one credit:
- A leak detection system which is capable of detecting a major water leak on the mains water supply within the building and between the building and the utilities water meter.
- The leak detection system is:
- Audible when activated
- Activated when the flow of water passing through the water meter/data logger is at a flow rate above a pre-set maximum for a pre-set period of time
- Able to identify different flow and therefore leakage rates, e.g. continuous, high and/or low level, over set time periods
- Programmable to suit the owner/occupiers’ water consumption criteria
- Where applicable, designed to avoid false alarms caused by normal operation of large water-consuming plant such as chillers.
