Drainage and Plumbing in the University Endowment Lands
Need a plumber in the UEL? This is the one place we work that is not a city. The University Endowment Lands is unincorporated provincial land, 14.13 square kilometres with 3,193 residents, organised under the University Endowment Land Act and run by the Minister of Municipal Affairs through the UEL Administration.
Different rules, different mains, different owner. We camera every line before we quote and you keep the footage.

Not a city, and the sewers are not fully separated yet
The UEL Administration owns and runs the water, sanitary and storm mains here, and its own 2026 Official Community Plan is honest about the state of them. The plan says future work is needed to fully separate sewer and storm systems, and puts separated sewer systems on the Infrastructure Rehabilitation Program list of future upgrades.
The same plan notes that portions of the storm and sanitary sewers in the plan area were built during the 1950s.
The Works and Services Bylaw still carries a live clause for it. In areas where dedicated storm sewers do not exist, storm services are temporarily connected to a combined sanitary and storm sewer. When separate storm and sanitary sewers get built to replace a combined one, separate connections have to be built to the property line for each house with an existing combined connection, and the old combined connection gets tied to the new sanitary connection at the property line.

Why water does not soak away up here
The residential UEL sits on a plateau at about 80 metres, above cliffs that drop roughly 70 metres to the beaches. The ground under it is a top layer of slowly permeable glacial till over a porous but very stable layer of Quadra sand, with thin layers of clay running through the sand that are also slowly pervious. The GVRD study of these cliffs says it plainly. Those clay layers block accumulated groundwater and cause drainage to the cliff face,. Geologists call the arrangement a perched aquifer.
So water arriving on your lot does not simply go down. It perches, travels sideways and eventually weeps out of the cliff. The same study names storm water flowing over the top of the cliff in severe storms as a significant cause of erosion in certain areas.
That has a direct consequence for how a drainage fix gets designed here. Digging a rock pit and walking away is not an option near the cliffs. A UBC stormwater detention study specifies an impermeable geomembrane liner below anything that facilitates infiltration, precisely to avoid soaking water into the upper soil strata that has been found to cause erosion at the Point Grey cliffs.
And it arrives in a lump. Of the 1,277.4 mm a year the UBC station records, 198.9 mm lands in November, 183.5 mm in December and 162.7 mm in January.

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.
University Endowment Lands drainage and plumbing FAQ
Yes, and it catches people out. The UEL is unincorporated land organised under the University Endowment Land Act, with the Minister of Municipal Affairs holding the authority and the UEL Administration running land use, bylaws, local streets and utilities. Development permits, building permits and inspection all go through the Administration. The arterials through the area are owned and maintained by the Ministry of Transportation and Transit on top of that.
Some of the system still is. The UEL’s own 2026 Official Community Plan says future work is needed to fully separate sewer and storm systems, and the Works and Services Bylaw still provides for storm services to be temporarily connected to a combined sanitary and storm sewer where a dedicated storm sewer does not exist. Portions of the storm and sanitary sewers in the plan area date to the 1950s.
Because of what you are built on. The plateau here is slow glacial till over Quadra sand with thin clay layers running through it, and those clay layers block groundwater and push it sideways toward the cliff face rather than letting it drain down. A camera on the perimeter tells you whether the tile is still moving that water, and the sump design has to assume water keeps arriving after the sky clears.
Not near the cliffs, no. Infiltration into the upper soil strata has been found to cause erosion at the Point Grey cliffs, and a UBC stormwater study specifies an impermeable geomembrane liner below anything that facilitates infiltration. The bylaw asks you to infiltrate on site only where it will not destabilise steep slopes, and to reduce post development flow back to pre development levels.
To splash pads. The bylaw’s storm sewer clause says roof drains are to be discharged to splash pads and not to service connections unless it is otherwise approved. If a plumber wires your roof leaders straight into the storm service here, they are working off a City of Vancouver habit rather than the UEL rule.
The canopy makes it likely. Metro Vancouver data puts UEL tree canopy cover at 80.4% in 2020, down from 82.4% in 2014. The bylaw sets minimum planting distances of 2 metres from sewer and storm services and 3 metres from catch basins, valve boxes and manholes, and the approved large boulevard species list includes Norway maple, common horsechestnut, red oak and western red cedar.
Often enough that the fall leaf load never wins. The UEL puts this on residents directly: clearing any lawn basins or catch basins of leaves and debris in front of your property is listed as a homeowner responsibility, along with mowing, litter and snow clearing. On a treed lot next to the park that is a bigger job than it sounds.
Not quite, and it matters for permits. Hampton Place is one of the University Neighbourhoods Association neighbourhoods on UBC campus land, alongside Chancellor Place, East Campus, Hawthorn Place and Wesbrook Place. It sits at the northeast corner of West 16th Avenue and Wesbrook Mall, about 957 units in 11 buildings, opened in 1989. We work there. We just work to the right authority for the address.
It came in waves rather than one build out. The first residential lots were sold by public auction in 1925, the Depression and wartime shortages slowed the 1930s and 1940s, and growth came in the 1950s, 1970s and 2000s. Area D alone counts 39 units from the 1920s, 111 from the 1950s, 220 from the 1970s and 743 from the 2000s.
No travel surcharge. The UEL, West Point Grey, Dunbar and Kerrisdale are all the same pricing.
