The Al-Mutahidah Towers are a pair of residential skyscrapers on the Viva Bahriya waterfront in Doha, Qatar. The total area of the complex is almost 150,000 square metres, with parking on three levels for more than 700 cars. Access to the beach is through a commercial area with a bakery and grocery store, café, beauty salon, babycare area, pharmacy and service centre.

The complex houses 14 lofts with spa overlooking the outdoor pool, 170 one-room, 120 two-room and 40 three-room apartments, 106 studios and 12 penthouses with roof garden, plus a wellness centre and gym, lounge and terrace, billiard and games room, multipurpose rooms, facilities for children and an administrative area. 14 terraced houses with separate entrances and views of the marina complete the complex. Valsir Triplus was chosen for the waste systems.

What it shows for a Finnish project

In a large residential complex the sound level of the waste pipe repeats in hundreds of apartments, so the choice is made once and with care. TRIPLUS is the three-layer mineral-reinforced push-fit waste system: less than 10 dB(A) at 2 l/s and 12 dB(A) at 4 l/s (EN 14366, certificate P-BA 105/2024).
