I’m confused between the options available for laying permanent underground pipes to transport and deliver water either to a storage tank or directly for irrigation.
I’ve laid out some of my questions below and request the experts to comment.
I expect to use a combination of drip irrigation, sprinklers/rain guns and in some cases, flood irrigation.
- What pipes are better for transporting water, HDPE, PVC or UPVC?
- What is the cost effective choice with longevity, low maintenance and ease of installation as the goals?
- Assuming the borewell yields 2" of water, I am being advised to lay 4" pipes beginning from the discharge nipple of the borewell. I’m told this will ensure better performance and longevity of the motor. Is this accurate?
- Assuming I lay 4" pipes for one borewell yielding 2". Can I join another borewell line yielding another 2" to this main 4" line? Or will I need a 6"pipeline in this case (as I’m being advised)?
- How deep should these pipes be laid underground?
- I plan to have the mouth of the borewell covered with a lockable manhole to deter theft and protect the well. Is this advisable?
- Since distances are high between the wells and the labour quarters, is it better to have the switch board mounted at the room location for safety and convenience or is it better to mount them near each borewell? What is the best way to protect the switchgear? Will building a small pump house nearer the wells be a better idea?
Please chip in with answers and add any other useful tips.
