Valley Ridge Pond Sediment Cleanup and Oil-Grit Separator Construction Project Water


Over the past few years, Water Services has been active in the community, conducting pond sediment removal on the golf course near hole #12 and most recently, installing an Oil & Grit Separator (OGS) in 2017. To finalize this work, Water Services and its contractor will be in your area to clean sediment from the storm pond near hole #13 and to install another Oil & Grit Separator (OGS) northwest of the Valley Ridge Drive N.W. and Valley Ridge Boulevard N.W. intersection.

Benefits of an OGS

An OGS is an underground pre-cast concrete structure that captures sediment, screens debris and separates oil from storm water runoff and snowmelt. The major environmental benefit comes in the form of improved downstream water quality by preventing contaminants and sediments from entering our streams and rivers through the storm drainage network. Additional benefits include the reduced chance of flooding in your area due to sediment buildup and backups in the pipes; as well, it can extend the life of a storm pond, thereby eliminating costly pond dredging and accompanying construction activity in your neighborhood.

Project Timeline

The project starts mid-October and is expected to be completed by mid-December 2018. This map identifies the work areas on Valley Ridge Drive N.W. as well as impacts to the overall community.

Construction Impacts 

  • Approximately 150m closure of westbound lanes on Valley Ridge Drive N.W. at the intersection with Valley Ridge Boulevard N.W. Eastbound lanes will accommodate two-way traffic.
  • Temporary traffic signs and barriers will be installed to control traffic flow.
  • Residents in the impacted area may be affected by traffic lineups and delays.
  • The pedestrian sidewalk will be closed within the construction area temporarily, during the sediment removal.
  • Speed limit through this area will be reduced to 30 kph.
  • Increased traffic to site (construction crews, trucks hauling materials to and from site).
  • Construction noise, vibration and possible dust during work hours (7 a.m. to 7 p.m. Monday to Saturday)
  • Note: No service disruptions to water or sewer. 

Project Information

A Questions + Information Session will be held in the River Room at the Valley Ridge Golf Course on Monday, October 1 from 5 p.m. to 8 p.m. Information will also be available by calling 311 or on the website
