Water supply, drainage, stormwater
Demand, risers, pumps, hot water, stormwater and drainage.
We calculate simultaneity on the real peak so pressure does not drop at the fixture and pipes stay quiet.
Water demand calculations to EN 806 with simultaneity factors
Internal water supply: cold, hot, circulation
Drainage and vented stacks to EN 12056
Pump stations, pressure zones, reducing valves
Stormwater and drainage, sumps
Water treatment: filtration, softening, metering
Hydraulic calculations
Plans and axonometric schematics

Equipment and valve schedule
Pipe schedule by diameter

Pressure drops on upper floors
We split into zones and add a booster set with variable-speed control.
Relocating a wet zone
We check the fall and stack position; where needed we design a macerator pump.
Grease trap for a restaurant
We size it from the menu and coordinate placement with service access.
Who approves water connections?
Georgian Water and Power in Tbilisi, United Water Supply Company of Georgia in the regions.
Is a storage tank required?
If mains pressure or flow is unstable, yes. Volume is sized on the building profile.
Is hot water circulation mandatory?
In hotels and clinics, practically always — so there is no wait at the tap.
Process
Survey and brief
We measure what exists: available capacity, pipe sizes, slab-to-ceiling heights, routing of services. We write the brief, the client approves it.
Concept and load calculations
Heating and cooling loads to EN 12831, electrical balance, water demand. This is where the kW and m³/h you will request from utilities are fixed.
Schematic design
Equipment layout, plant room areas, main shafts and routes. Agreed with the architect before the façade and ceilings close.
Detailed design
Plans, schematics, details, specifications and bills of quantities. Clashes are resolved in the model — pipe and duct meet on screen, not on site.
Technical conditions and approvals
Applications to utility companies, fire section review, closing of comments. We keep a log of what was submitted and when.
Tender and suppliers
We issue a procurement sheet with technical parameters and compare offers on service and spare-part availability, not price alone.
Site supervision
Scheduled visits, hidden-works records, change tracking. An installation error is corrected while the ceiling is still open.
Commissioning and handover
Air and water balancing against design, interlock testing, as-built documentation and an operating manual for the facility team.
