Catch Basin Installation Vancouver
Water pooling in the yard after every rain. Parkade flooding each November. Patio surface water with nowhere to go. When there is nothing at the low point to take the water, the low point is where it stays.
We install concrete and fiberglass catch basins tied to the storm sewer or to a daylighted outflow. Excavation, lateral tie in, City permit and landscape restoration are all part of the job.
Signs the site needs another basin
These are the symptoms that point at capacity rather than at a blocked chamber.
- Water running past an existing grate instead of into it during heavy rain
- A low spot in the lawn that holds water for days after the storm
- Ponding at the bottom of a driveway or a parkade ramp
- A patio that puddles every wet weekend regardless of how recently the drain was cleaned
- Water tracking toward the foundation instead of away from it
- Existing basins that are clean but still overflow at peak flow
- Silt and grit washed across a paved surface after every storm

When a property needs a new catch basin
If surface water pools where it should not, in the yard after rain, in the parkade during atmospheric river weather, on the restaurant patio every wet weekend, the property needs a catch basin. The function is simple. Capture surface water at the low point, route it underground through a lateral to either the storm sewer or a daylight outflow, and keep the surface dry.
Residential yard drainage. Heritage homes in Strathcona, Hastings-Sunrise and Mount Pleasant often pond because the original grading has settled over half a century or more. A yard basin goes in at the low point with a perforated lateral running to the existing storm connection or to daylight.
Driveway and patio drainage. A new patio or a resurfaced driveway routinely exposes a surface water problem that the older, more permeable surface was quietly absorbing. That gets a trench drain across the entrance plus a basin at the curb, tied to storm or daylight.
Parkade and commercial surface drainage. An existing parkade with capacity problems during heavy rain, where water runs past the existing drains and pools on the floor. Additional basins take the peak load, tied into the existing storm laterals.
Restaurant patio and outdoor seating. A new patio build, or an existing one with chronic drainage problems. Trench drain plus basin tied to the storm sewer, coordinated with City of Vancouver health and patio permits.
Every installation includes the municipal permit, excavation, the basin set with a concrete collar, the storm lateral tie in, backfill with drain rock and topsoil, landscape restoration in sod or pavers, and a certificate of work. We coordinate with the City inspector on every job.
Excavation, basin set and lateral tie in
Storm sewer tie in or daylight outflow
Tie into the storm sewer when
- The property already has a storm service connection at the line
- There is no fall available to a safe discharge point on the lot
- The contributing surface is large enough that a dispersion area would flood
- The site is commercial and needs documented compliance
Daylight outflow is the answer when
- The property has no storm connection, which is common on older East Van lots
- There is real fall away from the building to work with
- There is room to set the discharge well clear of the foundation
- There is space for a riprap dispersion bed so the outflow does not cut a channel

Get the basin sized before the next storm
Yard ponding every November? Parkade taking on water? A right sized basin and lateral is a thirty year fix, and an undersized one backs up the first time an atmospheric river tests it. We size against the contributing surface, not against a guess.
What Vancouver customers say
Ryan was great! My landlord called him to fix my blocked kitchen sink. He showed up the same day (on a Sunday) and fixed the problem. He even cleaned the sink and dried up all the water that had leaked before he got there. And he was very careful coming in and out of the house so my cat wouldn’t get out. I’d definitely recommend him.
Ryan is INCREDIBLE. He has been responding to all of us (four houses and families!) affected by a sewage back up. This is all on Boxing Day and beyond, in terrible weather full of ice, cold and rain. He is so knowledgeable, and knew what was needed right away. Just the top of his field I am sure. As well as that, he is incredibly calm, respectful, kind and fair. I am truly amazed by this person's capacity and competence in combination with his noble, calm presence in the face of a real mess. Thank you Ryan, so very much!
I had very positive experience with Mamba Services, Ryan was amazing to work with and took care of my drain issues in no time. He arrived on time, was very professional and efficient in carrying out the work. What impressed me was how honest he was in recommending needed repair. He was very patient in explaining the different options. I will certainly call them for future projects.
Had an excellent experience. Ryan was fantastic, it was an after hours call late in the evening and he showed up exactly in the time frame he gave. Took care of the kitchen sink issue within minutes all systems were running like new. Pricing was extremely reasonable, Ryan was patient and explained everything to me while fixing my problem. I would highly recommend this company for any plumbing work.
Ryan was efficient, experienced, and knowledgeable. He was able to squeeze me into his schedule with short notice and wasted no time with my appointment. He arrived on site inspected the issue, and was quickly at work with resolving the problem. I am very pleased with his service and honesty. He provided recommendations that will help assist me in future occurrences.
Catch basin installation FAQ, Vancouver
Yes. Any new lateral tie in to the storm sewer needs a plumbing permit from City of Vancouver or from the relevant municipality. We pull the permit, schedule the inspection and produce the stamped certificate for your property file.
It follows the contributing surface area, which is the area that actually sheds water toward the low point. A yard catch usually takes a smaller chamber on a four inch lateral. A driveway with a lot of hard surface behind it needs a bigger chamber and a six inch lateral. We measure the contributing area on site rather than picking a size off a catalogue.
Yes. Those get a heavy duty fiberglass basin with a cast iron grate rated for vehicle traffic. The work is scheduled overnight or on a weekend to keep tenant disruption down, and we handle the strata coordination.
Then the design goes to a daylight outflow, set well clear of the foundation with a riprap dispersion bed so the discharge does not cut a channel through the yard. It is common on older East Van lots that predate the storm sewer expansion. The permit is still required.
Whatever sits along the trench line gets excavated. We restore with sod, or with seed if you prefer, replant shrubs where the root systems allow it, and put back patio block and paver edging. The restoration cost is in the quote rather than turning up as an extra at the end.
Yes, and it is one of the more common jobs we take. A site that floods in heavy rain despite clean drains was usually built for less water than it now handles. We camera the existing system first so the upgrade targets the real restriction, then quote either extra basins, an upsized lateral, or a redesign of how the surface sheds.
Concrete and fiberglass chambers run thirty to fifty years in service. Cast iron grates go twenty five years and up and are replaceable on their own. The SDR-35 PVC lateral lasts fifty years and beyond. Proper drain rock and filter fabric at install is what gets you the top of those ranges rather than the bottom.
Yes, and on properties with high end finishes it is the sensible way to run it. We rough in the drainage work and your landscape contractor handles the final surface. The coordination is part of our quote so nobody is waiting on anybody.
Yes, and it usually should. If the drain tile is due, or a sump is going in, the same machine and the same open ground covers all of it. One mobilization, one round of restoration, and the yard only gets dug once.
