Water & Wastewater Plants
Structural engineering for water and wastewater plants: tanks, basins, operational buildings and repair of water-retaining elements.
Basins and tanks in water-impermeable concrete, plus the buildings around them.
What we take on
- Aeration, settlement and stormwater basins, circular and rectangular
- Tanks, clean water reservoirs and pump structures
- Operational and plant buildings with equipment loads
- Condition assessment and repair of existing basins
Crack width is the principal verification
It is not the ultimate capacity that decides the reinforcement but the limitation of crack width under restraint from hydration and temperature. Concrete mix, curing, pour sequence and joint layout therefore belong in the design and not on site.
Attack on the concrete
Wastewater is chemically aggressive. Exposure classes, cover and, where needed, additional protective systems are agreed with the operator, because they determine the maintenance cost of the coming decades.
Alteration during operation
A treatment plant cannot be switched off. We plan construction phases and temporary works so the treatment performance is maintained throughout.
