Workers drilling for soil samples in Uplands will likely impact noise and parking in the Oak Bay neighbourhood.

The work – started Aug. 11 and expected to run through Aug. 21 – is part of the ongoing Uplands sewer separation project. It impacts the 3200- to 3500-block of Midland Road, 3200 to 3400 Ripon Road, 3200 to 3300 Norfolk Road and 3200 to 3600 Beach Drive.

Uplands currently has a single-pipe system, built in the 1930s, to convey both sewage and storm water. During heavy rainfall, the volume of water frequently exceeds the capacity of the system, sending overflows into the ocean at the Humber and Rutland pumping stations.

This work on the Humber catchment is part of the first phase of a sewer separation in the neighbourhood.

In 2016, six options were developed for separating the combined sewer system into separate sanitary sewer and storm sewer systems to conform with provincial requirements. Oak Bay council of the day opted for a new gravity storm sewer system with the old combined sewer system becoming the new separate sanitary sewer system.

Other Humber catchment construction work includes building the roughly 3.5-kilometre new gravity stormwater system including mains, manholes, catch basins and leads, as well as new service connections to each house, new streetlights and two new ocean outfalls.
