Taif Independent Sewage Treatment Plant

Saudi Water Partnership Company, KSA

LUCAS® technology for secondary biological treatment at an Independent Sewage Treatment Plant


Taif, Saudi Arabia

In service date



Treated sewage water: 100,000 m³/day
Load: 32,000 kg COD/d

The project's challenge

Waterleau is the proud supplier of its proprietary LUCAS® technology for the Taif Independent Sewage Treatment Plant, located 70 kilometers southeast of Mecca in the Kingdom of Saudi Arabia.

The Taif Independent Sewage Treatment Plant will treat – by the project commercial operation date in 2023 – the domestic wastewater of 650,000 inhabitants from the most densely populated parts of Taif Governorate. The plant will have an initial capacity of 100,000 cubic meters per day, and will recover water as a valuable resource for agricultural and industrial purposes. In a later expansion phase, the plant will be able to produce as much as 270,000 cubic meters of treated water on a daily basis. This large scale project is part of the country’s National Water Strategy which aims to create a sustainable water environment by 2030, protecting natural water resources and providing a cost-effective sewage treatment and accessible water supply.

Waterleau's impressive technologies will allow us to collaborate and fulfill TAWZEA's ambitions as a water and wastewater infrastructure leader in Saudi Arabia.

TAWZEA's CEO Mohammed Halawani

The Saudi Water Partnership Company (SWPC) awarded the development, design, complete financing, construction, commissioning, 25-year operation and maintenance, then transfer (BOOT) of Taif independent sewage treatment plant to a consortium comprising Cobra Instalaciones y Servicios S.A., and International Water Distribution Co. Ltd. (TAWZEA) at a levelized cost of 1.07 SAR per cubic meter of water, in a unique BOOT setup, making it a truly independent project.

Similar independent sewage treatment plant projects are in the pipeline for the major cities of Buraydah, Tabuk and Madinah.

Waterleau's solution

Waterleau’s contribution to the project in Taif is to provide its patented LUCAS® technology, which allows a compactly built biological treatment stage operated with low energy consumption. Recent innovations in settler design, sludge densification and smart process control make Waterleau's LUCAS® technology an extremely beneficial and interesting solution for such large-scale projects. The benefits are distinct in cost-efficient construction, reliable operation and low operational expenditures.

The process and technology train

The LUCAS® system is at the core/the beating heart of the sewage treatment plant. Taif ISTP includes the following process steps:

  • Fine-screening and fat/grease removal
  • Primary settling and peakflow equalization
  • Secondary treatment with LUCAS® technology
  • Tertiary filtration and chlorination
  • Sludge thickening, anaerobic sludge digestion, sludge dewatering and sludge drying
  • Cogeneration of heat and power from biogas

The LUCAS® system has both a low construction footprint and a low carbon footprint compared to other secondary treatment technologies such as conventional activated sludge systems, sequencing batch reactor systems, and biofilm on carrier based systems.

It fits seamless into the vision of The Saudi Water Partnership Company and the developing consortium, and synergizes with Taif independent sewage treatment plant its valorization of reclaimed bio-effluent, green electricity, green heat and dried bio-solids.
