Around 9,000 people in Mission live beyond the sewer lines, on forested acreages, hillside lots, and older rural homes where the tank may be buried and the records long gone. Add close to 1,900 mm of rain a year and a slow system shows itself fast. Valley Septic pumps, cleans, inspects, and repairs septic tanks across Mission, from Silverdale to Dewdney, with the slope, the driveway, and the weather planned for before the truck leaves Chilliwack.
Mission systems often work around slopes, trees, long driveways, and winter rainfall. Pumping removes the solids load, but it also gives the technician a chance to spot obvious issues before wet-season symptoms get worse.
Older Mission homes may have buried lids, unclear tank locations, or systems that were inherited without service records. If you do not know the last pump date, it is worth getting the tank checked before it backs up.
Pumping and cleaning are one and the same visit here: the tank is emptied, we check what we can see while it is open, and you get a date for the next one. From Heritage Park to the Fraser waterfront, and out to Hatzic, Ruskin, and Stave Falls, we schedule routine and urgent pump-outs across the whole city.
Inspections, alarms, repairs, emergencies
For Mission's rural and semi-rural properties, pumping is only the start. The same crew inspects, troubleshoots alarms, answers emergencies, and repairs what turns up.
BC doesn't require an inspection when a Mission home changes hands, but it is the most useful check a buyer can make. We open the tank, check the baffles and filter, and tell you whether the field is coping with the rain.

Learn MoreOn a hillside lot the pump chamber does the heavy lifting, and its alarm is the first warning. We find the failed float, pump, or panel and get the system moving before it overflows.
Learn MoreBuried lids, cracked risers, worn baffles, failed pumps, and broken lines on older Mission systems: we repair what the pump-out or inspection finds, before the drainfield pays for it.
Learn MoreSteep approaches, soft shoulders, forested lots, and lids far from the parking spot all get planned before the truck is dispatched.
Close to 1,900 mm of rain falls on Mission each year. We time pump-outs so an overdue tank isn't adding load to a drainfield that is already soaked.
If the tank came with the property and no records, a pump-out gives you a clean starting point and a realistic date for the next service.
Systems near the lake sit close to wells and flood-prone drainfields. We service them on schedule and flag anything that needs an authorized person's eye.
Our certified crew keeps its training current and leaves you with a service record, which matters when Fraser Health or a buyer asks for one.
Warning signs
On Mission's slopes the drainfield usually shows trouble first. If you see any of these, especially after a wet stretch, book before the backup:
Before the truck arrives
A few details about the slope, the driveway, and the tank's history make a Mission pump-out faster and more useful.
Let us know about steep driveways, soft shoulders, or tank lids away from the parking area before the truck is dispatched.
Mission's wetter months can expose overloaded tanks and saturated drain fields, especially on older rural systems.
If the tank came with the property and no records, pumping gives you a baseline for the next maintenance schedule.
Tank pumping
The visit, step by step, and how often a Mission tank should be on the calendar.
Steep driveway, soft shoulder, buried lid? We work that out first, so the truck parks where the hose reaches and the lawn stays intact.
On older Mission properties the lid can take some locating. We expose it, note its position for next time, and open the tank.
The full load of liquid and solids comes out, and we check baffles, filter, and sludge depth for anything the rain will make worse.
You get a service record and a date for the next pump-out, which is the start of a maintenance history if the property never had one.
Mission disposal rules
Septage pumped in Mission is taken to the JAMES wastewater treatment plant in Abbotsford, which Mission and Abbotsford share. Its trucked liquid waste facility accepts domestic septage only from properties inside the two cities, where it's treated with the region's sewage.

About 9,000 of Mission's roughly 35,000 residents aren't connected to municipal sewer, and most of them are on septic systems (a few use holding tanks). Urban areas are generally on sewer, while rural and semi-rural properties are more likely to be on septic. If you're not sure, the City can confirm whether your property is connected. If you are on septic, knowing where the tank is makes every service faster.
Mission homeowners follow BC's Sewerage System Regulation, which Fraser Health administers. You're responsible for maintaining your system according to its maintenance plan and keeping maintenance records; many systems installed before 2005 have no plan, so your own pumping records fill that gap. New systems and most repairs have to be designed and filed with Fraser Health by an authorized person before work starts. Maintaining a system in a way that creates a health hazard, such as sewage surfacing in the yard, carries a $345 violation ticket, and Fraser Health can order repairs. Neither BC nor the City of Mission sets a mandatory pumping interval.
Yes. The Hatzic Lake management plan identifies septic systems as a concern around the lake, including systems close to drinking water wells on Hatzic Island and drainfields that flood when water levels rise. Note that the lake's shoreline is split between the City of Mission and the Fraser Valley Regional District. If you're near the lake, keep your tank pumped on schedule, keep vehicles and structures off the drainfield, and have an authorized person look at the system if it's been through a flood.
Mission's sewer bylaw doesn't allow a septic tank to be connected or discharged to the municipal sewer. When a property hooks up to sewer, the old tank has to be pumped out and decommissioned as the bylaw requires. Check the City's requirements before your connection is scheduled, and book the final pump-out for just before decommissioning.
BC doesn't require a septic inspection when a home is sold, but it's one of the most useful checks a buyer can make. A pump-out and inspection shows the tank's condition, whether baffles and filters are intact, and whether the drainfield is coping, and Mission's heavy rainfall (close to 1,900 mm a year) is quick to expose a struggling field. Sellers should gather pumping records and any Fraser Health filing or maintenance plan for the system.
Tell us what you know when booking. Older rural properties sometimes need extra time for access and lid location before pumping can begin.
Across Mission
From Silverdale and Cedar Valley up to Stave Falls and Steelhead, and east through Hatzic and Dewdney to Deroche, Valley Septic covers every corner of Mission.
On the Hatzic Lake shoreline or outside city limits? Give us the address when you book so we can plan disposal.
Outside Mission? We also cover Abbotsford, Chilliwack, Langley, and Hope.
Give us the address, a note on the driveway and where the tank is if you know, and the last pump-out date if you have it. We'll plan the visit around the access and the weather.
