While village water and rain catchment have their place, we wanted a reliable deep well we could control. This post documents how we found groundwater at 25 meters, drilled a 6-inch bore, and installed a 4-inch submersible pump with a 1.5-inch outlet.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Hitting_Water_at_25_Meters\"><\/span>Hitting Water at 25 Meters<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>We hired a local well-drilling crew who brought in a rotary rig mounted on a truck. Based on nearby wells, we expected to hit water between 20 and 30 meters. Drilling started early in the day and went smoothly through layers of clay, sandy soil, and compacted earth.<\/p>\n\n\n\n<p>At <strong>25 meters<\/strong>, the signs were clear: drilling speed increased, the slurry returned with moisture, and the water flow stabilized \u2014 all solid indicators of a viable aquifer. The team drilled a little deeper to around 28 meters to ensure a clean zone and reduce sediment risk.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Installing_a_6-Inch_Well_Casing\"><\/span>Installing a 6-Inch Well Casing<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>We chose to install a <strong>6-inch PVC casing<\/strong> \u2014 a step above the common 4-inch size. The extra diameter gives more flexibility for pump servicing, reduces friction, and allows greater flow potential in the future if we ever upgrade. The bottom section of the casing includes slotted screens, allowing water to enter while keeping out sand and silt.<\/p>\n\n\n\n<p>After inserting the casing, the annular space was filled with coarse gravel to act as a natural filter. The top was sealed with concrete to protect against surface runoff and contamination.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Submersible_Pump_4-Inch_with_15-Inch_Outlet\"><\/span>Submersible Pump: 4-Inch with 1.5-Inch Outlet<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Once the well was flushed and settled, we installed a <strong>4-inch submersible pump<\/strong> designed for deep wells. The pump delivers water via a <strong>1.5-inch outlet<\/strong>, offering a solid balance between volume and pressure \u2014 perfect for filling tanks, irrigating crops, and general farm use.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Installation_Steps\"><\/span>Installation Steps:<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Electrical Setup<\/strong><br>A dedicated line was run from our main panel to the well, using waterproof conduit. A safety breaker and surge protection were installed near the control panel.<\/li>\n\n\n\n<li><strong>Pipe &amp; Fittings<\/strong><br>We used high-pressure 1.5-inch PVC pipe to handle the output, with proper threaded fittings, rubber gaskets, and stainless clamps to ensure long-term reliability.<\/li>\n\n\n\n<li><strong>Cable Management &amp; Safety<\/strong><br>The power cable was zip-tied along the pipe every meter. A separate <strong>nylon safety rope<\/strong> was tied to the pump and secured at the well cap to act as a retrieval backup in case the riser pipe fails.<\/li>\n\n\n\n<li><strong>Lowering the Pump<\/strong><br>The pump was lowered carefully to a depth of about <strong>22 meters<\/strong>, keeping it 2\u20133 meters above the bottom of the well to avoid sediment intake. We used a pulley system and took our time.<\/li>\n\n\n\n<li><strong>Well Cap<\/strong><br>The well head was sealed with a custom-fitted cap with grommets for the pipe, cable, and rope. A small air vent was added to prevent vacuum lock during pumping.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Testing_and_First_Run\"><\/span>Testing and First Run<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>After wiring up the controller and priming the output line, we flipped the switch. Within seconds, <strong>clean, strong water<\/strong> surged from the pipe. We ran the pump for 30 minutes to clear any remaining drilling debris and check output.<\/p>\n\n\n\n<p>The result: consistent flow, no noticeable silt, and solid pressure. We routed the pipe to a series of water tanks that now feed the entire property via gravity or pressure pumps as needed.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Drilling for water in isaan chumphon buri\" width=\"840\" height=\"473\" src=\"https:\/\/www.youtube.com\/embed\/ih3Hbo2SMDQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Lessons_and_Final_Thoughts\"><\/span>Lessons and Final Thoughts<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Drilling a deep well is a major milestone for any rural property. Here\u2019s what we learned:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Go with a 6-inch casing<\/strong> if you can. It gives you room to upgrade or service the pump easily.<\/li>\n\n\n\n<li><strong>Choose a high-quality submersible pump<\/strong> with enough head pressure to handle your specific depth.<\/li>\n\n\n\n<li><strong>Don\u2019t skip safety details<\/strong> like the nylon rope, surge protection, or proper venting.<\/li>\n<\/ul>\n\n\n\n<p>This one-time investment gives us total independence from outside water sources \u2014 a crucial step toward resilience on our land.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>If you&#8217;re in Thailand and considering your own well, I\u2019m happy to share contractor details, pump specs, or lessons learned.
