Water & Wastewater Works

ROSCO provides specialized Water & Wastewater Works, including water supply networks, wastewater systems, stormwater drainage, and associated utility infrastructure in accordance with project scope, approved drawings, and specifications.

Water and Wastewater Network Delivery

The service covers excavation, network route preparation, installation of water and wastewater pipelines, associated structures, connections, and manholes according to project requirements.

It also includes stormwater and surface water drainage works for sites, roads, and developed areas, with the required network components designed and constructed according to approved project requirements and site conditions.

Installation, Testing, and Handover

ROSCO focuses on proper construction sequencing and coordination between underground networks and other site services, while monitoring material quality and installation and completing the required inspections and tests before acceptance.

The service is suitable for developments, communities, facilities, commercial and industrial sites, and government projects requiring new or upgraded water, wastewater, and related drainage networks.

The Water & Wastewater Works scope covers network and associated utility works according to each project's requirements, including:

• Water supply networks and transmission lines.
• Wastewater and sewerage networks.
• Stormwater and surface drainage networks.
• Excavation and preparation of network trenches and routes.
• Installation of pipes, fittings, connections, and associated network components.
• Manholes and structures associated with wastewater networks.
• Connections to existing networks where included within the project scope.
• Pumping stations and associated structures where included in the project scope.
• Backfilling and reinstatement of work areas following network installation.
• Inspection, testing, disinfection where applicable, and network handover preparation.

ROSCO supports water and wastewater projects through specialized capabilities in utility networks and underground works, including:

• Water Network Installation: Installing water supply pipelines and network components according to approved drawings and project requirements.
• Wastewater Network Construction: Delivering sewer lines, manholes, and associated structures.
• Stormwater Drainage: Constructing stormwater drainage networks and associated components.
• Excavation and Installation: Preparing network routes and carrying out excavation, installation, and backfilling works.
• Network Connections: Coordinating and executing connection points within the approved project scope.
• Underground Utility Coordination: Coordinating water and wastewater networks with other existing and planned site utilities.
• Inspection and Testing: Completing required inspections and tests to verify network readiness.
• Field Execution Management: Coordinating site teams, equipment, and network installation activities.

ROSCO follows a structured methodology for water and wastewater network projects:

1. Drawing Review: Reviewing network routes, specifications, connection points, and site requirements.
2. Route Preparation: Preparing work areas and mobilizing the resources and equipment required for installation.
3. Excavation and Trench Preparation: Executing excavation and preparing trench bases according to network requirements.
4. Network Installation: Installing pipes, fittings, manholes, and associated network components.
5. Connections and Backfilling: Completing network connections, backfilling, and reinstatement of work areas.
6. Inspection and Testing: Conducting required inspections and tests to verify network integrity and readiness.
7. Handover Preparation: Addressing observations, completing required documentation, and preparing the networks for handover.
