Construction site managers are responsible for the health and wellbeing of the staff who operate on their work sites. This includes providing safe, clean drinking water that complies with the UK standards that regulate drinking water on construction sites. Careful water management is key to fulfilling this obligation, as construction operations undertaken on site produce various types of wastewater that aren’t safe for human consumption. Site operators risk contaminating drinking water if waste is not properly handled.
The type and extent of welfare facilities required, including drinking water provisions, depend on the nature of the construction work being undertaken. The specific welfare needs, such as washing facilities and showers, are influenced by the nature of the work and must comply with health and safety regulations.
This guide explains how construction site managers can understand the laws they’re expected to adhere to, assess their worksite’s water management needs and determine how to best keep wastewater separate from drinking water.
Understand Water Standards
Construction site managers must be familiar with UK drinking water regulations. The water provided to workers must meet the standards set out by the Water Supply (Water Quality) Regulations 2016 in England (or the equivalent regulations in Scotland, Wales and Northern Ireland). These laws cover microbiological, chemical and physical metrics that must be met to confirm that water is safe to drink.
Water supplied to site workers should be fresh, potable and stored or dispensed using clean, appropriate infrastructure such as mains-fed systems or properly maintained water containers. Managers should routinely check water sources, particularly on long-term sites, to confirm that they continue to meet safety standards.
Wastewater generated during construction activities must be managed in line with the Environmental Permitting (England and Wales) Regulations 2016, as well as the relevant Water Industry Act 1991 provisions. These regulations prohibit unauthorised discharges into watercourses, public sewers or the ground, and require permits or consent for disposal in most cases. Wastewater systems must be properly designed, monitored and maintained to prevent contamination of drinking water supplies and minimise environmental harm. Keeping drinking water infrastructure physically separate from wastewater collection points is a basic legal and practical requirement.
Assess Your Construction Site
Before selecting water supply solutions, assess the layout and demands of your site. Consider the number of workers, the location of welfare facilities and how often the water will be used. Sites without access to mains water may need bowsers or tanks, each of which comes with maintenance and monitoring obligations. There is a wide range of water supply options available, allowing you to choose solutions that best fit your site’s specific requirements.
The topography and proximity of contaminated areas such as concrete washout pits or fuel storage zones should also be evaluated. These assessments help prevent cross-contamination and allow you to plan water points that are accessible, safe and practical. It is essential to be prepared with contingency plans and resources to ensure continuous access to drinking water.
Plan How You Will Manage Wastewater
Wastewater from construction activities must be managed to avoid polluting the drinking water supply or the surrounding environment. This includes grey water from welfare units, water contaminated by materials such as concrete or plaster and runoff from rain falling on contaminated surfaces.
Managers should identify where wastewater will be generated and how it will be collected, stored and removed. Proper segregation and clear discharge points help prevent wastewater from entering drinking water systems.
Contracts with licenced waste carriers should be arranged to collect and treat wastewater off-site when on-site treatment is not an option.
Provide Consistent Drinking Water Supplies
By following these best practices for managing construction site water supplies and wastewater, construction managers can remain compliant with UK water standards and safeguard their staff’s wellbeing. For more information or assistance with construction site water solutions, contact us today.

Maintaining Facilities and Equipment
Maintaining welfare facilities and equipment on construction sites is essential for safeguarding the health, safety, and wellbeing of construction workers. Regular upkeep of welfare facilities—including toilets, washing facilities, and rest areas—helps prevent the spread of illness and supports a healthy working environment. Construction site managers must ensure that these facilities are cleaned and disinfected frequently, with a consistent supply of soap, towels, and clean drinking water always available to meet the daily needs of the workforce.
The reliability of water sources is critical on any construction site. Water tanks, pumps, and associated equipment must be routinely inspected and maintained to guarantee a safe, uninterrupted supply of drinking water. This not only helps prevent contamination but also ensures compliance with UK safety requirements. Any equipment used for water storage or distribution should be kept in good working order, with regular checks to confirm that water quality meets the necessary standards.
Site layout plays a key role in maintaining safety and accessibility. Welfare facilities should be strategically located to be easily accessible to all workers, while also being positioned away from potential hazards. Adequate ventilation and heating in rest areas and changing rooms are particularly important, especially during winter or on remote sites, to provide a comfortable and healthy environment. Ensuring that changing rooms are available for workers who wear special clothing or handle hazardous substances helps prevent cross-contamination and supports overall site safety.
Secure storage solutions, such as lockers, are vital for protecting workers’ personal effects and special clothing. This not only helps maintain order on site but also gives workers peace of mind that their belongings are safe while they focus on their tasks. Providing enough tables and seating in rest areas allows workers to take proper breaks, reducing fatigue and supporting productivity throughout the construction project.
Regular inspections and audits of welfare facilities and equipment are required to identify and address any issues promptly. Construction site managers should follow the guidelines set out by the Health and Safety Executive (HSE) and comply with all relevant UK regulations, including the Health and Safety at Work etc. Act 1974 and the Construction (Design and Management) Regulations 2015. These regulations mandate that welfare facilities are properly maintained and that workers have access to clean drinking water, washing facilities, and rest areas at all times.
In challenging conditions—such as remote locations or during winter—extra attention must be paid to maintaining heating, ventilation, and lighting in welfare areas. Ensuring that hot water is available and that all facilities remain functional despite adverse weather is key to keeping the workforce healthy and the project on track.
By prioritising the maintenance of facilities and equipment, construction site managers can reduce risks, support worker health, and help ensure that construction projects are completed safely, efficiently, and in full compliance with industry regulations. This commitment to high standards benefits not only the workforce but also the overall success and reputation of the construction site.
