4. Laying the Pipeline

Start placing the main pipeline in the trench, ensuring that joints are secure and free of any debris. For PVC pipes, use primer and cement to bond the joints and create a leak-proof seal. For polyethylene pipes, use appropriate fittings and clamps to secure the connections.

5. Proper Gradient

For effective drainage, your pipeline should have a slight gradient. A 1% slope (for every 100 feet, a drop of 1 foot) is recommended to facilitate gravity flow and prevent water pooling within the system.

6. Backfill the Trench

Once the pipeline is securely laid and checked for leaks, backfill the trench with the excavated soil. Compact the soil lightly to reduce air pockets; however, avoid excessive compaction that could restrict water flow. Leave the surface level slightly higher than the surrounding area to account for settling over time.

7. Install Valves for Control

Incorporate valves along your main pipeline to control water flow in various sections of your lawn effectively. This will allow for easier maintenance and adjustments when necessary. Valve boxes should be installed at ground level for easy access.
