The project also aims at providing treated effluent to be used in irrigation and planting purposes
The water reuse project, developed by Haya Water in Muscat governorate is one of the major development projects as it is directly linked to people’s environmental health and safety. Moreover, it will be a qualitative leap for Muscat residents.
As part of the master plan for Muscat water reuse project, work is underway to implement a network for distributing treated water produced by the treatment plants currently under construction.
Commenting on this project, Eng. Omar al Wuhaibi, CEO of Haya Water said: "لإhe water reuse project aims at protecting the environment against pollution resulting from the outflow of the traditional sewage tanks especially the outflow of untreated sewage has adverse impact on health and result in spread of diseases and epidemics. Moreover, it causes offensive smell that makes life intolerable in the affected areas."
“The project also aims at providing treated effluent to be used in irrigation and planting purposes. This in turn will reduce the consumption of fresh water in such works. The treatment process is designed as per the world-class standards and best practices in this field using the most advanced technologies. The Plants are designed to treat sewage in three phases which allows us to use the treated effluent in irrigation and plantation purposes.
All Haya Water treatment plants use the Membrane Bioreactor (MBR) technology, one of the best technologies used in the world to get high quality treated water free of any pollutants’ he furthered.
"Haya Water implements a 290,000 Maters long network for the transportation and distribution of treated water. The network covers the provinces from wilayat of Greater Muttrah to the wilayat of Barka the main pipeline of 1000 millimeter diameter and between 100-500 millimeter diameters for the subsidiary conduits. These networks will transport the treated effluent to beneficiaries", he continued.
About 50 million liter per day of treated effluent has been earmarked for irrigation purposes by Muscat Municipality to irrigate parks and public garden as well as the plants and trees on Sultan Qaboos Road. Muscat Hills project is provided by 3,475,350 liters of treated effluent per day, compared to 38,217 liters per day for Diwan of Royal Court, 29,533 liters per day for the Aviation Club, 842,424 liters per day for Wentworth Golf Course and 62,344 liters per day for W.J Towell, he furthered.
“The water treatment plants now produce about 75 million liters of treated water per day to be increased to 140 million liters per day when the project is completed by 2018. About 80% of Muscat residents will be connected to the sewage networks. This in turn will contribute to increasing the greenery in Muscat provinces and wilayats’, he added
As for the use of treated effluent in increasing the underground water reservoir, Haya Water CEO said ‘Many studies are conducted by the company in collaboration with respective organizations such as Sultan Qaboos University and others to benefit from the treated effluent in increasing the ungrounded water reservoirs and other uses such as injecting water to the inner of the earth. The treated effluent may also contribute to reducing the salinity problem faced by some coastal areas. The high demand for underground water always result in decreasing their levels which result in salty water seeping into the layers carrying fresh water. To address this problem, treated water is pumped to this area. This in turn will reduce the seeping of salty water into the layers of fresh water. It should be noted that this practice is used by a number of countries worldwide.
Features of the treated water
"Haya water treatment plants produce treated effluent meets the international parameters of treated effluent. The treated effluent produced by Haya Water is under direct and monitoring by the Ministry of Environment and Climate Affairs. Haya water also established a specialized laboratory to test the treated water before being transported and distributed onto beneficiaries. Samples are also collected regularly from the different STPs to ensure that they meet the parameters stipulated in the ministerial decision No 93/145", he continued.
Haya Water endeavors to protect environment against pollution by transferring sanitary drainage water into treated water . The company plays an active role in the development process witnessed by the Sultanate under the wise guidance of H.M Sultan Qaboos Bin Said. The company takes inspiration from the wise directives of His Majesty Sultan Qaboos bin Said which help the company to overcome the challenges and ensure proper implementation of this major project.
It is worth mentioning that Haya Water, established in 2002, is a fully state owned company. The company designs, builds and operates water reuse projects in Muscat governorate. The company seeks to maintain protect of environment and society; a goal sought by the company through its projects.
The company employs 343 Omani experienced staff in the different departments with the company which represents more than 72% of total manpower. The project contributed to creating a number of indirect employment opportunities with Haya contractors.
