Domestic water services
Domestic water design is about delivering the right flow, pressure and temperature at every outlet while keeping the system hygienic. Oversized systems stagnate; undersized ones fail at peak. We size from realistic demand and design for safe operation.
Request a fee proposalWhat the service covers
- Cold water supply, storage and boosting
- Hot water generation and distribution, including secondary return
- Pipe sizing from loading units and realistic demand profiles
- Legionella risk considerations in design: temperatures, dead legs and stored volumes
- Incoming mains and water authority liaison inputs
When clients typically need it
- A building is being refurbished and existing water services need to be assessed or replaced
- New hospitality, leisure or commercial uses change the water demand
- Pressure or temperature complaints suggest the existing system is not performing
- A new build needs a coordinated water services design
Deliverables
- Water services schematics and coordinated layouts
- Demand, storage and pipe sizing calculations
- Plant space and builder's work requirements
- Specification inputs for tanks, boosters and hot water plant
Common project constraints
- Limited plant space for storage and boosting
- Existing distribution with unknown sizing or condition
- Phased works in occupied buildings requiring temporary supplies
- Balancing water hygiene against energy and storage targets
How we approach it
- Size from how the building will actually be used
- Minimise stored volumes and dead legs to reduce hygiene risk
- Coordinate plant space early with the architect and M&E team
- Plan phasing and temporary supplies for occupied buildings
