Aligning to its mission of achieving sustainable development in planning, establishing and maintaining infrastructure projects and optimising the national-housing the national-housing sector through outstanding performance, The Ministry of Infrastructure Development awarded Metito the project to construct PS1OB Storm Water Pumping Station and Rising Main from Sheikh Mohammed Bin Zayed Road to the Golf near Al Khan area.

This fourth phase of upgrading the Fifth Industrial Square in Sharjah is aimed at providing the city with a new Pumping Station and Rising Main for efficiently handling potential Storm Water in Industrial Area 5. The station has a total capacity of 345,600m3/day making it the biggest of its kind in the GCC.

Furthermore, the project features 1800mm diameter Rising Main to discharge storm water from a new drainage system at the E311 highway of the Fifth Industrial Square in Sharjah to the sea in Al Khan area.

Scope of Work 

The pumping station consists of an inlet screen area and three sumps: A, B and C.

These sumps are provided to host three different sets of pumps which discharge the collected storm water to the sea. Sump A houses Storm Water Pumps (SWP01/02/03), Sump B houses the Dry Weather Flow Pumps (DWFP01/02/03), and Sump C houses the future Storm Water Pumps (SWP04/05/06).

The inlet screen area consists of the following units:

  • Bar Screen installed at the inlet of this pumping station to avoid rubbish delivered to the pumping station. This screen must continuously be removed and cleaned to protect the pumps chambers.
  • Mechanical bar screens (SC01/02/03)
  • Screen screw conveyor(C01)
  • Screening compactor (CM01)
  • Washing water system which serves the Washing Pumps (WP01/02) and the Washing Water Storage tank (TK01)

Key Benefits

In case of floods, due to heavy rain during the winter season, the storm water drainage system will divert the storm water and rainfall to the PS10B Storm Water Pumping Station will then discharge it to the sea through the pipeline and outfall system. This will help ensure that no environmental, physical or other damages occur in the area’s infrastructure and surroundings which makes it a progressive and sustainable solution that is both cost saving and preventative.

Treated Sewage Effluent Polishing Plan, Mixed Bed Bio-Reactor (MBBR/Ultra-Filtration/ Reverse Osmosis)

Introduction

Dubai Parks and Resorts is an iconic project and the Middle East’s largest multi-themed leisure, entertainment, and theme park destination. The establishment is located on Sheikh Zayed road in Dubai, UAE, strategically located midway between Dubai and Abu Dhabi International Airports. Dubai Parks and Resorts is spread over 25 million square feet and features more than 73 attractions and rides spread across three theme parks: Motiongate Dubai, Bollywood Parks Dubai and Legoland Dubai. The park also includes: Lapita, a global Marriott operated family resort hotel (known as Hotel Lapita’’); River park; and a complementary and centrally located retail, dining and entertainment district connecting the three theme parks and the hotel.

An integral part of the infrastructure development for Dubai Parks and Resorts is the Lagoon which is strategically constructed across the establishment to enhance the overall landscaping and beautification of the resort. Considering the year round hot climate in the UAE, it is expected that the lagoon water may experience considerable evaporation. To address this challenge the Treated Sewage Effluent Polishing Plant, Mixed Bed Bio-Reactor (MBBR/Ultra-Filtration/Reverse Osmosis) project was developed as a sustainable solution.

Scope of Work

The scope of works awarded to Metito included the complete design engineering (process, mechanical, electrical, automation & control), equipment supply, and the installation and commissioning of the treatment process system and plant.

  • TSE Polishing:In this package, water from five streams: TSE water from Dubai Municipality and Dubai Parks STP: cooling tower blowdown and spent backwash water from carbon filters, UF systems and high-rate sand filters of the side stream filtration, are all treated by the UF-RO system to produce makeup water for the lagoon.
  • Side Stream Filtration:Overflow water and water drawn off by skimmer pumps from the lagoon is treated in high-rate sand filters and UV units to remove suspended impurities and disinfect the water. The disinfected water is then aerated and discharged back into the lagoon.
  • Pool Water Filtration & Chlorination:Overflow water and water is drawn by skimmer pumps from the Water Wheel Pool, another attraction in Dubai Parks, is passed through Dual Media Filters. Filtered water is then chlorinated to disinfect the water and discharge back into the pool.
  • Pumping Stations:The scope of work in this package is limited to providing the pumps and associated valves and piping for subsequent uses.
