The growing seaside community of White Rock, British Columbia, is clustered on a steep hill around a 5-mile sandy beach in Semiahmoo Bay. Over time, the sanitary and storm sewer systems grew with a mix of materials, including PVC, asbestos cement and concrete. The entire system needed replacing.

Consulting engineers decided that the PVC SDR 35 gasketed sewer pipe and fittings system from Royal Building Products was the best choice. It is lightweight, durable and easy to install. “It gave us a lot of flexibility because two PVC pipes could be laid side-by-side. Twin trenching allowed installation to be done very quickly and efficiently,” says David Chan, branch manager with Alpin & Martin Consultants. “This could not have been achieved as effectively with a thicker-walled pipe such as concrete. Thinner walls meant narrower trenches, less disruption to the community, and fewer road cuts.”

Given the underground surprises, PVC made design changes easier. “We were able to install several more lineal feet in a day compared to other types of products,” Chan says. “Flexibility is critical when dealing with less-than-ideal ground conditions and an older infrastructure with different materials. You need to come up with answers quickly. The ability to move things around when needed made it easier to work in and around utilities in a safe manner.”

Crews installed more than 1,100 miles of storm and sanitary sewer pipe, 34 manholes and 130 service connections without any significant problems. 800/232-5690; www.royalbuildingproducts.com.
