Your irrigation system will consist of the most efficient types of sprinklers and nozzles available to the homeowner to ensure minimum waste caused by run-off and evaporation and will also address those areas that require specialized watering.

Yes, having a fully computerized irrigation system will save you valuable time. Rather than having to water your lawn and garden areas by hand, you will now be able to use that time for other activities. Rain sensors are installed with each irrigation system ensuring that watering will only occur during times of little or no rain thus reducing the amount of water required. A computerized irrigation system also allows a homeowner to spend extended time away from their residence with out the worry of their gardens.

Oliver Irrigation Ltd. will custom design and install an irrigation system that best suits the customer needs and requirements taking into account water pressure, landscaping and budget requirements.

There are a number of ways this process is accomplished. This will depend upon what type of landscaping is already established. In large lawn areas, we use what is call a ditch witch pipe puller which pulls the pipe underground and leaves a single line. If we need to get more pipes in one trench we first cut the existing turf and fold it to one side and then use a trenching machine. In some cases where we cannot get the machinery on site we will dig all trenches by hand. All of these methods result in little disruption of landscaping and after approximately one week, the lines will disappear once watering resumes. Oliver Irrigation Ltd. will install a very clean and professional job with little disruption to the homeowner’s landscaping.

Once the system is installed, we will set the controller to what we find to be best for your landscaping needs. We will leave you the controller manual to study and after one week to ten days we will send a technician back to go over the system with you while showing you all the features of the controller. This provides time to ensure that the system has been operating properly, gives the homeowner time to study the manual and is also an opportunity to fine tune the system - if required. You will also be provided with a laminated zone list located next to the controller. This will let you know exactly where your zones are located.

The water that is used by your irrigation system is supplied by the same source as the water you drink, cook and bathe with. Pesticides, fertilizers and/or animal faeces can collect in water pooled around your sprinkler heads, creating a potential for the contaminants to be drawn back through the sprinkler irrigation system (by means of backflow or backsiphonage) and into your home. It is for this reason that you must have a properly functioning Backflow Prevention Assembly protecting your drinking water.

Under section 14 of the Municipal Water Works By-Law No. 4848 the Backflow Prevention Assembly connected to your irrigation system must be tested annually. Backflow Prevention Assemblies and Devices break or wear out, just like the parts of a car. By having your Backflow Prevention Assembly tested annually, you will help to ensure that the drinking water supplied to your home remains safe. Because of this the City of Vancouver created this By-law to help insure the safety of your drinking water. We have Certified Backflow Assembly Testers on staff who have attended a rigorous training course, and are certified by the American Waterworks Association, British Columbia Section, to test your Backflow Prevention Assembly. Certified Testers can inspect, test, repair or replace all Backflow Prevention Assemblies and Devices.

Oliver Irrigation Ltd. warranties all installations against defects in material and workmanship for a period of 2 years from the original date of installation. To retain this warranty, yearly service is required. This involves a spring start up and winterization in the fall at a small fee to the customer and must be performed by an Oliver Irrigation Ltd. technician. Our service vehicles are all equipped with radios communicating with the office, to ensure quick and reliable service to the customer in case of troubleshooting.
