Most homes in Langley and South Surrey run on city water and city sewer. Drive out to Campbell Valley, Glen Valley, parts of Brookswood or the farm parcels of South Surrey, and that changes. The house may draw water from a well on the lot and send its waste to a septic tank and field out back. Both are the owner's responsibility, both are regulated by the province, and neither gets much depth on a standard home inspection.
The buyers who end up happy with these properties are the ones who asked for the paperwork before removing subjects. Here is what that paperwork is, and the Surrey rule that puts a septic obligation right on title.
First, find out what the house is on
Do not assume from the listing. A rural address can be on city water and septic, a well and sewer, or both private systems. Surrey suggests checking its COSMOS map, and says that if there is no City sewer nearby, or the property pays no annual sewer charge, it may be on septic. In the Township of Langley, staff can tell you what services front a property.
The well: what the province expects
Groundwater used only for household purposes needs no licence in B.C. Under the Water Sustainability Act, household means drinking, cooking, cleaning, fire prevention, water for pets or animals kept for household use, and a garden of up to 1000 square metres. Water a hobby farm or a riding arena from the same well and you may need a groundwater licence. Worth asking on any acreage with livestock or crops.
Every water supply well drilled, altered or decommissioned after February 29, 2016 must be registered in the provincial database, GWELLS, with the driller's report going to the province and the owner within 90 days. Older wells are often missing. The province strongly encourages owners to register them, but it is not required.
So search GWELLS for the property first. No record is common on older homes; it just means you rely on the seller and your own testing.
The well records travel with the house
This is the rule most sellers do not know. Under section 81 of the Groundwater Protection Regulation, a well owner must keep every well identification report, construction report and flow test report until the well is decommissioned, and on a sale must transfer them to the new owner. It is in the regulation, not a courtesy.
The province's guidance for buyers and sellers says sellers should disclose the well record, water quality results, pumping or flow test results, and whether any wells on the property have been closed. It also notes your mortgage lender may ask for some of this. If a seller has nothing, that tells you something.
If the property carries a groundwater licence, the licence and any unpaid water rentals transfer to the buyer. Ask for the latest invoice and settle arrears before completion.
Owner duties after you buy
The well cap must stay securely attached and in good condition. The casing must stick up at least 0.3 metres above ground, and the ground must slope away from the wellhead so water does not pool. A well that is part of a drinking water system needs an identification plate, which the province supplies free.
An unused well cannot simply be left. After 5 years out of service it must be deactivated if you plan to use it again, or decommissioned if you do not. Older acreages sometimes have a forgotten second well near an old house site or barn. Ask.
Testing the water
A private well owner is responsible for the water quality. HealthLinkBC's guidance is to test for bacteria at least once a year, or right away if clarity, colour or taste changes, and to run chemical testing when a well is completed and then annually. The common concerns in B.C. groundwater are nitrates, fluoride, and metals such as arsenic, lead, copper and manganese. Nitrates are more likely near farming, and near septic systems built or maintained badly. A neighbour's clean result says nothing about your well.
On a purchase, I suggest making a recent bacteria and general chemistry test a condition of the offer, sampled by a qualified lab from the CALA directory rather than handed over by the seller. A test only describes the water on the day it was drawn.
Township of Langley residents with private wells can join the Township's Private Well Network for free. Members get 20 per cent off bacteria and general chemistry testing at Element Materials Technology, and their results go anonymously onto a groundwater map. A cheap habit for the first year of ownership.
The septic system: who can touch it
Septic systems are governed by the Sewerage System Regulation, and Fraser Health accepts filings and handles enforcement here. Under section 6, only an authorized person, meaning a registered onsite wastewater practitioner or a professional engineer, can build or maintain one. An owner may do work on their own land only under an authorized person's supervision.
The authorized person files the system with the health authority, then within 30 days of completion gives the owner the plans, a maintenance plan and the letter of certification. Section 10 requires the owner to maintain the system to that plan and keep records.
So on a septic property, ask for the filing, the as built drawing showing where the tank and field are, the maintenance plan, and the pump out records. HealthLinkBC notes systems built after May 30, 2005 come with a maintenance plan, and owners of older ones can have an authorized person write one. Tanks typically need pumping every 2 to 5 years.
The Surrey rule that sits on title
Surrey goes further than the province. Under the City's septic requirements for building permits, published December 2020, a building permit on a septic property needs an active Fraser Health filing, a sizing report, and a restrictive covenant registered on title before the permit is issued.
The covenant requires the owner to protect the disposal field, retain an authorized person, and send the City a certification letter every two years confirming the system has been maintained to plan and the effluent is within its design limits. If the letter does not come, the City may hire an authorized person, enter the property to do the work, and bill the owner.
Properties in the Agricultural Land Reserve larger than 0.81 hectares, or 2 acres, are exempt. So it turns up mostly on smaller unsewered South Surrey lots built or renovated under that rule. Buy one and the covenant becomes yours on completion. Your lawyer or notary will see it on title. Ask for the recent certification letters before you remove subjects.
A short checklist for buyers
- The GWELLS record, or confirmation that none exists.
- Any well construction, identification and flow test reports, which the seller must pass on.
- A recent water test from a qualified lab.
- Any groundwater licence and its latest invoice.
- The septic filing, as built drawing, maintenance plan and service records.
- A septic inspection by an authorized person, separate from the home inspection.
- In Surrey, a title check for a septic covenant and its certification letters.
None of this should scare anyone off a rural property. These homes just need a buyer who reads the file before the deal is firm. My post on what happens at subject removal covers how to build these conditions into an offer.
Where this comes up locally
In Langley, wells and septic are most common on the acreages of Campbell Valley, around Fort Langley and in parts of Brookswood, where the Brookswood-Fernridge Community Plan explains how servicing shaped lot sizes. If the land is in the ALR, read Fort Langley acreage and the ALR too. In South Surrey, the rural pockets are where you will meet the septic covenant.
Looking at a property on a well or septic? Send me the address and I will tell you what to ask the seller for and help you write the conditions. Selling one? Gather these records now, and start with a home value estimate.
