Water Collection & disposal
Client : USAID/Aqaba Water Company
Funding Agency: : USAID
This project is based on design-built-operate FIDIC contract (Gold book 2008 ,DBO) for the new expansion for Aqaba North Wastewater Treatment Plant based on activated sludge process.
The key stakeholders are: The Client is the USAID and Aqaba Water Company(AW), The Contractor is Arab Towers Contracting Company (ATCCO) and the Employer’s Representative is Arabtch Jardanah (AJ).
The Wastewater Treatment capacity for the Existing Aqaba Mechanical & Natural WWTP is 21,000 m³/day. The natural ponds will be decommissioned and cleaned so as to be emergency ponds for the treated effluent. The current flow received at the plant is around 17,000m³/day while the capacity of the mechanical WWTP is 12,000m³/day.
The Scope of work for the DBO contractor include:-
- Design, construct and operate a new conventional activated sludge wastewater treatment plant with average design capacity of 28,000m³/day.
- Clean the natural WWTP in order to be used asemergency ponds for treated effluent quantities.
- Rehabilitation the existing mechanical treatment plant.
The detailed components are:-
Investigate and do the required work to rehabilitate the existing mechanical treatment plant.
Emptying, drying and maintaining the existing natural ponds to be used for emergency.
