Doha Festival City, Al Shamal Road, Doha, Qatar


To provide the water retention (and stormwater management) system to collect and harvest rainwater for use at the IKEA mega store.


The system supplied involves the installation of 17,000 sets of VersiTank® VT840 in five layers in an excavated pit with overall depth (pit bottom to ground surface) of 5.8m. Measuring 42m length x 24m width x 2.1m height with an estimated volume of 2,100 m3, the modular VersiTank is able to accommodate maximum inflow rate of 570 L/s and outflow rate of 24 L/s.

The retained rainwater is used for irrigation of landscaped gardens and miscellaneous cleaning at IKEA’s 32,000m2 flagship store and its immediate vicinity. This provision is especially beneficial in a rain-scarce region, where precipitation is almost nil in summer months.

Doha Festival City is the largest shopping mall in Qatar. Upon completion, the almost half million sq m iconic mega complex will host more than 500 retail and dining outlets, feature an entertainment and leisure complex, automotive showrooms and international hotels and convention centre.
