PWA Future Surface & Ground Water Outfalls

Abu Hamour Outfalls : 10 Km Length off-shoreline in Sea Bed .

• Length identified based on EIA Study & Two Discharge Modeling

Studies to Find out Least Environmental Impact to Marine Environment.

• Commissioning Operation in End of 2020

New District of Doha Outfall & South of Al Wakra Outfall

• Still under Locations Identification & Preliminary Concept

Design.

• Length will be identified based on EIA Study & Discharge Modeling Studies

Groundwater Aquifer: Gulf Countries Council Guidelines for Treated Water Injection Criteria

MWH

2B PWA New Drainage Concept

Drainage Strategy aligns with the Qatar Integrated Drainage Master Plan (QIDMP)

• Surface water runoff collected via roadway gullies and directed to infiltration trenches.

• Groundwater collection system to control groundwater below 4 m.

2C

Collected Urban Surface & Groundwater will be

discharged to:

• Attenuation Tanks

• Treatment Tanks

• Deep Wells Injection up to 400m deep GW Aquifer (Short Term Solution)

• Strategic micro-tunnel for off-site conveyance to Sea Outfall (Long Term Solution)

Umm Er Radhuma

Rus Gypsum

Dammam

Upper Rus

2D

Collected Rural Surface & Groundwater will be discharged to EFA or Wetlands Systems

• EFA mainly for Surface Water

Intermittent Storage

• Wetlands mainly for Surface

Water beside Treated Sewage

Effluent Storage

• Wetland can be upgraded to

Public Parks based on MMUP-

SWM ponds-general guidelines

2E

03Environmental Compliance of

Drainage Master Plan SurfaceWater & Groundwater Drainage

Systems Long Term Plan.

Develop Recycling System for Surface Groundwater & Storm Water including

Treatment Measure by Wetland

followed by Reverse Osmosis Technology.

Combine both Treated Water with Recycled Water within One

Treated Water Network to Cover

the Needs of Municipalities, District Cooling Plants and Industries for

water use for different Purposes.

Complete Public Surface Groundwater Network and

Develop Long and Deep Outfall

Discharge to Sea as an Emergency Discharge Measure.

PWA’s Planned GSW System « New thinking « to Reuse GSW as New Water Resource.

04 Recommended Mitigation Measures By Developer

4A

• Qatar Sewerage and Drainage Design Manual, 1st Edition June 2005: Volume 3 SW Drainage, page21.

• Qatar Sewerage and Drainage Design Manual, 1st Edition June 2005: Volume 8 Developers Guide, page 27.

• Particular Specification for use in Qatar and section in QCS 2014

• Ashghal SuDS Initiatives

• LRDP and Expressway programme

• Promotion of the use of hydraulic modelling techniques for SUDS

schemes.

• Geocellular storm water attenuation tanks

Recommendations for SuDS Initiatives :

• Arched Geocellular Storm Water tanks

Preventative measures

• Pervious surfaces

• Filter drains

• Swales

• Infiltration devices
