Irrigation Works
From Water Intake to Infield Distribution
Intake Works
Construction support for water abstraction points, approach works and intake protection.
Sedimentation Basins
Basins that slow water movement and help settle suspended material before distribution.
Pipe Laying
Mainline and submain installation with attention to alignment, levels and pipe protection.
Infield Systems
Distribution systems that carry water from main lines into the working irrigation areas.

Recommended Add-On Services
Useful Services WASEWI Can Adopt
Based on WASEWI's water, sewer and irrigation focus, these services fit naturally with the company profile and can be offered alongside pipe laying and network construction.
HDPE Butt-Fusion Welding
Butt fusion joins HDPE pipes by trimming the pipe ends square, heating them on a plate, then pressing them together under controlled pressure while they cool. It creates a strong, continuous joint for pressure water and irrigation pipelines.
Estimation, Costing & BOQ Support
Project costing helps clients understand expected pipe quantities, fittings, equipment, labor and site-related costs before work begins.
Manholes, Chambers & Inspection Points
For sewer networks, proper access points make maintenance, jetting and future inspections easier.
