Scope of Work
Details/Specifications
1
Piping Provision and Installation
Provide and install pipes with a nominal diameter of 90 millimeters, pressure nominal of 16 with High-Density Polyethylene material, including all necessary materials and fittings.
2
Lagoon Crossing Method
Employ directional boring or open-cut techniques, ensuring compliance with environmental regulations.
4
Route Demarcation
Implement visible marking and install warning signs to ensure safety during installation and operational phases.
5
Piping Connection Methodology
Utilize electrofusion or butt-welding techniques for joining High-Density Polyethylene pipes to secure leak-free joints.
3
Trenching and Backfilling Operations
Excavation to a minimum depth of 70 centimeters below ground level. Use proper bedding materials to support the pipe and compact backfill to required density levels.
6
Gate Valves Integration
Incorporate gate valves with a nominal diameter of 90 millimeters, pressure nominal of 16 for flow control and maintenance purposes.
7
Strainer Installation
Install a strainer with a nominal diameter of 63 millimeters, pressure nominal of 16 to prevent debris entry.
8
Flow Meter Incorporation
Integrate a 3-inch diameter flow meter for accurate monitoring of water usage.
9
Manhole Chamber Construction
Construct Reinforced Cement Concrete chambers to provide access to valves, strainer, and flow meter.
10
Float Ball Valve Inclusion
Install a 2-inch float ball valve to automatically adjust and maintain the water levels within the tank.
