Where we drill water wells
Nanaimo Well Drilling drills across Electoral Areas A, B, E and F of the Regional District of Nanaimo, taking in Cedar and Yellow Point, Nanoose Bay, Errington and Coombs, and Parksville. We drill on Gabriola Island and across monitored aquifers throughout the region under the Groundwater Protection Regulation. We read the GWELLS records for your address before we quote, and we get back to you within 24 hours of your inquiry.
We bring our drill rig to your site, but local geology dictates whether we drill fractured rock or screen in sand and gravel.
What's under your property — bedrock or sand and gravel?
The regional district tracks 9 bedrock aquifers and 13 sand-and-gravel aquifers across our area. That difference shows up in what the job costs. At Cassidy, sand and gravel yields roughly 20 US gallons a minute from a median depth around 13 m. In nearby bedrock at Cedar and Yellow Point, wells average 50 m deep for 2 US gallons a minute — four times deeper for less water. Errington wells average 60 m in shale for 3 US gallons a minute, while wells on Gabriola Island average 34 m in bedrock. We confirm which geological layer sits beneath your property before we give you a quote.
What do the records say before we drill?
Every well drilled in British Columbia under modern reporting rules has a public record listed in GWELLS. These aquifer records show median depth, yield, and overall ranges to give us a realistic estimate for your lot. Aquifer 220 at Errington contains 325 recorded wells with a median depth of 60 m, a median yield of 3 US gallons a minute, and a low end of 1. Aquifer 709 on Gabriola Island lists over 1000 wells, with a median depth near 34 m and median yield around 4.5 US gallons a minute. Regional tracking showed 16 of 22 aquifers below normal levels in June 2026, with Errington dropping 0.32 m per year over 5 years. None of these statistics guarantees what a single hole will produce. This data helps us narrow down expectations before you spend money.
Areas we serve
- CedarIn Electoral Area A, sandstone bedrock sits next to Cassidy gravels that give ten times more water.
- Nanoose BayIn Electoral Area E, hilltop bedrock yields to gravel flats below, with artesian flow logged near the peninsula.
- Gabriola IslandIn Electoral Area B, fractured bedrock feeds wells, with sea water intrusion noted near Silva Bay and Degnen Bay.
- Errington & CoombsIn Electoral Area F, shale rock yields modest water flow, with fluoride and sulphur present in some wells.
- ParksvilleIn Parksville, sand and gravel deposits yield much more water than bedrock, with artesian flow in Quadra Sand.
We also serve Yellow Point, Cassidy, South Wellington, Whiskey Creek, Hilliers and Mudge Island.
Your property and your neighbour's lot can have totally different ground, and aquifer records show us what to expect. To find out what your address is likely to give, book a site assessment.
