PÖYRY PROJECT CARD
Hydraulic and operational implementation planning for the managed aquifer recharge project in the Turku region covered water supply in full, the hydraulic and operational design of the pressure and gravitational mains and distribution network. Operational challenges were presented by the long pressure and gravitational mains and large water volumes to be transferred.
Central design areas
Transfer pumping for pre-treated water
•Pressure main SG1200 (27 km)•Design content:
•Dimensioning of main equipment•Hydraulic grade line analysis•Pressure surge analysis and
dimensioning of surge protection systems
•Specification of control methods•Specification of the leakage
monitoring system
Well pumping for recharged water
•Lines PEH180…400, LM450…800•Design content:
•Dimensioning of main equipment•Hydraulic gradient analysis •Pressure surge analysis •Specification of control methods
Gravitational main for treated water
•Gravitational main SG1200 (60 km)•Flow control through a water turbine•Design content:
•Dimensioning of main equipment•Hydraulic gradient analysis during
operation changes•Pressure surge analysis and
dimensioning of surge protection systems
•Specification of control methods•Specification of the leakage
monitoring system•Preparation of the water turbine’s
operational specification
