The systems used to collect, treat and dispose of wastewater in Abu Dhabi have been developed by the Sector to protect public health and minimise the environmental impact of wastewater but also generate a range of valuable products which can be used as a source of water, nutrients and energy to support the Emirate’s sustainable development goals.

The activities of the wastewater sector are collectively known as Sewerage Services and are defined by Law No (2) of 1998 (as amended) as:

  • (a) Collection of wastewater from premises; (b) Treatment and processing of wastewater; and (c) Disposal of the products of wastewater treatment. The Bureau enforces the legal framework for the wastewater sector, illustrated below, which aims to:
  • (d) minimise the risk to public health and the environment; (e) minimise public nuisance from sewerage services; (f) maximise the social and economic benefits of sewerage services; and (g) develop public confidence in recycled water and biosolids disposal.
  • (c) Disposal of the products of wastewater treatment.

The Bureau enforces the legal framework for the wastewater sector, illustrated below, which aims to:

  • (d) minimise the risk to public health and the environment;
  • (e) minimise public nuisance from sewerage services;
  • (f) maximise the social and economic benefits of sewerage services; and
  • (g) develop public confidence in recycled water and biosolids disposal.

Wastewater legal framework

2014-01-30 1210591.png

The sector has an agreed terminology to describe the components of raw wastewater and the products of wastewater treatment which are illustrated below. The legal framework for the sector applies to all these components and products.

Wastewater terminology

Sewerage services are provided throughout the Emirate by Abu Dhabi Sewerage Services Company (ADSSC) with the support of a number of other private operators that deliver contracted treatment capacity to ADSSC or collection, treatment and disposal facilities for small, remote developments such as labour camps and hotels.

In going about our everyday lives, each person in Abu Dhabi generates approximately 275 litres of wastewater each day which contains a range of chemical and microbiological pollutants. The characteristics of wastewater are closely related to the catchment and are heavily influenced by industrial and commercial discharges. The water returned to sewer (RTS) is only 30% of the water supplied to a typical household because most of the desalinated water supplied is used for external uses such as irrigation, swimming pools and car washing.

A wastewater collection network receives wastewater from domestic, commercial and industrial buildings and conveys it to the wastewater treatment works. It is typically made up of small diameter (<200mmØ) local networks which discharge into a large diameter (<400mmØ) trunk sewers that convey the wastewater to the treatment plant.

There are three types of collection networks operated in the Emirate:

(a) Gravity sewers are the most common and simple systems. They use gravity to convey wastewater away from the point of discharge.

(b) Vacuum sewers are relatively new and used where ground conditions are difficult. Wastewater is sucked away from the point of discharge by an air flow.

(c) Pressure systems are typically used in conjunction with gravity systems to avoid deep excavations. Wastewater is pressurised by a pump and passed through a rising main to a point of discharge.

ADSSC operates over 250 pumping stations and 6800km of sewers and rising mains across the Emirate.

The discharge of non-domestic wastewater into public collection systems is controlled through the Trade Effluent Control Regulations 2010 and supported by codes of practice for a range of low risk trade effluents.

Wastewater treatment plants use a range of physical, chemical and biological treatment process to reduce the quantity of chemical and microbiological pollutants in the wastewater. Treating wastewater ensures that the treated effluent can be discharged to the environment without causing a significant impact or reused for non-potable purposes.

The Emirate’s three major wastewater licensees operate over 35 wastewater treatment plants in the Emirate. These treatment plants are typically based on the activated sludge process and treat flows ranging from 100m³/d to 300,000m³/d.

The map below illustrates the location of the nine largest treatment plants that receive over 95% of the wastewater generated in the Emirate.

Wastewater disposal is the safe and sustainable environmental discharge or reuse of the products of wastewater treatment. The sector calls any treated effluent that is reused Recycled Water and any sewage sludge that is treated and reused Biosolids.

The Emirate of Abu Dhabi has a long history of using Recycled Water for irrigation of public open space and was one of the first countries to implement World Health Organization initial guidelines on wastewater reuse in 1975. The use of Recycled Water plays an important part in meeting the Emirate’s growing need for non-potable water to support irrigation, cooling and industrial demands.

Biosolids contain valuable nutrients and organic matter and have the potential to be used as a fertiliser, soil conditioner or fuel. The Emirate is reviewing options for exploiting this valuable resource.

ADSSC carry out most of the disposal of recycled water and biosolids in the Emirate and operates over 150km of recycled water transmission networks that transfer recycled water to end-users or environmental disposal sites. ADSSC currently also transfer all treated biosolids to landfill sites by road transport.

The disposal of recycled water and biosolids by licensees is regulated in the Emirate through the Recycled Water and Biosolids Regulations 2010.
