Even on sites without water,
we can drill a well.
From Sapporo and Kitahiroshima to All of Hokkaido, we drill wells. With our hydraulic rotary compact drilling rig, we handle depths of standard 50 m, up to 70 m. With a trailer fully equipped with living facilities, we can also take on remote sites without water and long-term jobs.

What We Can Do
Remote areas, no water source, long-term work. We have three strengths that let us handle all kinds of difficult sites. If you've been told "it can't be done" or "it's impossible," talk to us first.
standard 50 m, up to 70 m
With our hydraulic rotary compact drilling rig, we drill from a standard 50 m up to 70 m. Ideal for sites where shallow wells lack water, or for projects targeting mid-depth aquifers. ※ Sites with hard bedrock layers are not supported.
No water source?
We can still drill in remote areas
Large-capacity tank equipment is on hand, so we can haul water from rivers and ponds. We can handle sites with no mains water or no water sources nearby.
Long-term jobs
are no problem
Our dedicated trailer is fully equipped with a toilet, rest area, water supply and 100 V power. We can stay and work even in remote areas with nothing around, so there is no need to hire another contractor for long or large projects.

Hydraulic rotary compact drilling rig (standard 50 m, up to 70 m)
On spacious sites, we can drill from a standard 50 m up to 70 m. Fully equipped with water tanks, generators, casing pipes and more.With large-capacity tanks, even on sites with no water source we can drill by hauling water from rivers and ponds, and the trailer is also equipped with 100 V power.
Work trailer with full living facilities and 100 V power
Our dedicated solar-powered trailer is fully equipped with a toilet, rest area, water supply and 100 V power. Even in remote areas with nothing around, we can stay on site while working, and work is possible on sites without power. Long-term jobs are welcome too.
Engine & drive mechanism
We use a highly reliable Japanese-made engine. Its stable output handles long hours of drilling. We do our own maintenance, so it always arrives on site in top condition.
High-output suction & pressure pump
Used for mud water handling during drilling and pumping tests after completion. On sites without a water source, it also hauls water from rivers and ponds into the tanks.
We own professional-grade equipment, so we never need to subcontract. With no middleman margins and direct construction, we can offer excellent value for money in our work.
Types of wells we can build
Well TypesBecause drilling involves engine noise, as a rule we decline jobs in densely built-up urban areas. We give priority to sites with ample work space and little noise impact on neighbors. (Urban sites can also be discussed depending on conditions.)
Household wells
Garden watering, car washing, refilling pools and more. Very effective for cutting water bills.
Emergency wells
As an emergency water source during disasters and water outages. A hand pump can be added.
Agricultural wells
For irrigating fields, greenhouses and orchards. Large volumes supported.
Commercial wells
For car washes, laundries, factories and other businesses. Cut costs.
Snow-melting wells
A Hokkaido specialty. Groundwater for snow-melting systems in parking lots and entrances.

About pricing
PricingThe cost of drilling a well varies greatly depending on the site's geology, depth, purpose and access conditions. For this reason, we provide individual estimates.
About the site survey
Start by contacting us by email or LINE. We'll ask about your purpose and wishes and, as far as we can, give you a rough idea of the expected cost. Then we'll discuss a site survey with you.
What the estimate includes and what is extra
- Separate from the drilling work cost, materials such as casing (protective pipe), pump and piping are charged extra
- With our hydraulic rotary compact drilling rig, we drill from a standard 50 m up to 70 m supported (soil layers, sand and gravel layers, etc.).Sites with hard bedrock layers are not supported.
- Sites without mains water can be handled with our large-capacity tanks (transport fee extra)
- Long-term jobs supported (for distant sites, lodging and travel costs extra)
- If a notification to the local government is required, we can help with the procedure (extra fee)
- Water quality testing for drinking use is arranged separately
Payment timing
If you book work for the following fiscal year or later, we hold a booking deposit of ¥200,000 (applied to the construction price) at the time of booking, and before work starts you pay 50% of the total minus the booking deposit.
① Water purification system for drinking (specifications depend on water quality, so we quote after confirming water flow and quality)
② Sand filter (sand separator, when there is a lot of sand)
③ Cold and freeze protection (depending on the outdoor installation, discussed on site)
④ Drilling beyond 50 m (drilling work and materials for the excess, around ¥200,000–¥300,000 depending on geology; billed after the work is completed. The maximum depth is 70 m. We will always consult you before deciding whether to keep drilling.)
⑤ Piping into the house, special piping, electrical work and the electrical circuit for the well pump (these may fall within the scope of your house builder, etc.)
Guarantee in case no water comes out
We carefully assess the likelihood of groundwater in the pre-drilling survey, but depending on geological conditions, there are rare cases where no water comes out or not enough water is obtained. In that case, you pay only the 50% deposit, and we do not charge the remaining 50%.
※ Equipment transport costs, actual material costs, and lodging for long-term jobs may by their nature be charged to you. Details are explained in writing at the time of contract.
Well drilling process
Our ProcessInquiry & consultation
Contact us by email or LINE. We'll ask about your purpose and wishes.
Site survey (paid; amount agreed in advance)
We survey the site conditions, underground obstructions and nearby wells, and propose the best method. Since the survey fee depends on site conditions, we agree on the amount with you in advance.
Estimate
Based on the survey results, we present the work and price in writing, and explain carefully until you are satisfied.
Contract & required notifications
After signing, if a notification to the local government is required, we help with the procedure (compliant with Sapporo City and Kitahiroshima City ordinances).
Drilling work
We drill with the hydraulic rotary compact drilling rig, checking the strata and groundwater as we go.
Casing & pump installation
We insert the protective pipe and install the pump and piping. Water quality is also checked.
Completion & handover
We explain how to use it and how to maintain it. Feel free to contact us about any problems afterward.
Until the well water settles
Before It SettlesA well cannot be used like mains water from the day it is finished. It settles down little by little over several weeks to several months. How long this takes varies greatly depending on the strata, and we cannot guarantee it. Please understand this before you decide.
| Stage | Approximate period | What may come out | What we ask of you |
|---|---|---|---|
| Right after drilling | During the work | Mud water, sand, heavy cloudiness | We clean the well and run a pumping test |
| Right after handover | A few days | Slight cloudiness, sand, iron (rusty water), odor | Please run the water and use it every day |
| Settling period | Several weeks to several months | Occasional sand and cloudiness | Keep using it. If sand continues, please contact us |
| Stable | ─ | Almost clear | If you will drink it, have the water tested |
Why sand comes out when you stop and restart the pump
The water is clear while pumping continuously, but when you stop the pump and start it again, sand comes out. This is a common phenomenon in wells. The cause is not the amount of water but the surge at the moment of start-up.
What to do if sand continues
If that still doesn't solve it, options include installing a sand filter (sand separator) or placing a sand settling tank above ground. Depending on the strata, the screen may need to be reinstalled.
These countermeasures are not included in the well drilling estimate, but we offer the "Sand & Turbidity Water Supply System" (quoted according to the installation location).
Depending on the strata, sand and turbidity may continue indefinitely
Land that was originally seabed and land where the seabed rose up to become mountains or plains have thick layers of uniform fine sand, and sand easily enters the well, so sand tends to keep coming out for a long time.
Clay layers (including volcanic-ash clay): on land where these are thick, the fine particles stay suspended in the water and do not settle easily, so the cloudiness is hard to remove and may never fully go away.
This is due to the underground water veins and strata, and is not something we can control. Please understand this before you decide.
For such sites, we offer our own original countermeasure equipment. We can propose various systems to match the water quality once water is flowing, so please consult us. See the "Sand & Turbidity Water Supply System"
Please understand in advance
- Well water is not clear and odorless like mains water from the start. It may come with cloudiness, sand, iron (rusty water) or odor.
- The period until it settles can take several weeks to several months, and since it depends on the strata, we do not guarantee it.
- Using it every day and keeping the water running is the shortcut to stability. If it goes unused for a while, it may turn cloudy when you resume.
- If the pump starts and stops repeatedly at short intervals, sand comes out more easily.
- In sandy ground of seabed origin and in clay layers, sand and turbidity may continue for a long time (in some cases indefinitely). This is due to underground water veins and cannot be controlled by us.
- In strata that produce sand, countermeasures such as a sand filter may be needed separately (we offer our original "Sand & Turbidity Water Supply System").
- For drinking use, a water quality test and a water purifier are required. Water quality is judged from the test results after drilling.
Sand & Turbidity Water Supply System
Sand & Turbidity Solutions
Depending on the strata, sand and turbidity may not settle even with continued use. Equipment cannot eliminate sand and turbidity completely, but by improving not the well itself but "how the water is received", we can make the water good enough for practical use.
We propose two original methods we have actually built on sandy sites, chosen to match the water quality once water is flowing. Costs are quoted according to the installation location and piping. Your existing well pump stays in use.
Settling tank method
For sandy sites / for the period until the well water settles
- To remove accumulated sand, just open the drain cock at the bottom. The pump runs automatically and pushes the sand out
- Because the tank is large, the pump restarts less often and the well settles more easily.
- Components: 200 L stainless steel pressure tank, sand filter, PP cotton filter, check valve, pressure control, piping
Water purifier method
For sites with mainly turbidity / as a finishing stage after the sand has settled
- Since cartridges clog quickly when there is a lot of sand, this method is for after the sand has settled.
- It can also be expanded by adding a purifier after PLAN A.
- Components: well water purifier, sand filter, PP cotton filter, check valve, pressure control, piping
Common notes
- Your existing well pump stays in use. We set the pressure to match the pump's capacity (head)
- Indoor installation is assumed. For outdoor installation, please consult us separately about freeze protection
- This equipment targets sand and turbidity (particles).Iron and manganese dissolved in the water are not covered.
- For drinking use, we recommend a water quality test
- Costs are quoted individually according to the installation location (indoor, machine room, piping distance, etc.). The same applies to orders combined with well drilling
- Travel costs are extra depending on distance. If local piping conditions require more materials, we will consult you beforehand
FAQ
FAQ[Work process and payment]
Order → site survey → final estimate → 💰 50% deposit paid → scheduling → delivery & setup → drilling → well cleaning → water flow confirmed with a temporary pump → 💰 remaining 50% + additions transferred → casing, pump and inner pipe installation (continued to prevent internal collapse) → optional work (purification equipment, piping into the house, etc.) → explanation → delivery complete
※ Payment is made twice: a 50% deposit (at order) and the remaining 50% plus additions (once water flow is confirmed with a temporary pump). The deposit covers initial costs such as arranging and delivering materials (casing, etc.), drilling work and fuel. The permanent installation of the casing, pump and inner pipe continues after water flow is confirmed, to prevent internal collapse. If no water comes out at all, you pay only the 50% deposit and no balance (the deposit covers actual costs such as drilling, delivery and fuel). Whether water will come out cannot be promised in advance due to various factors such as geology and the limits of drilling depth, so the risk of no water is shared between us and the customer.

Inquiry form FORM
Nojima Well Workshop is the well drilling division of Nojima Giken, which is based at a garage workshop in Sapporo, Hokkaido.
We apply Nojima Giken's way — "not combining off-the-shelf products, but investigating, thinking and building" — to the specialized field of water and land. We carefully survey the geology, terrain and water source conditions that differ for each site and design the best drilling for that site. In our self-built mobile workshop trailer, we go anywhere in Hokkaido.
For maintenance after the well is completed, home repairs and handyman work, we stay with you for the long term together with our sister service, "Neko no Boss."
