According to the Metro-Vancouver guideline, the irrigation restriction will start on May 1st, so setup your irrigation controller or clock according to the following instruction:

We are all experiencing very tough times in light of COVID-19, and we must be committed to doing what we can to flatten the curve. Beside the many instructions that we are receiving from the health authorities, we always hear “wash your hand frequently “. As a member of Water Resources Community, we would like to remind that every drop of clean water matters, especially during this pandemic. Our resources are limited, and we should use water in a smart manner and wisely.

As hydraulic designer of piping systems in our waterworks, we deal with following definitions on a regular basis:

. Pipe material and structure: homogen vs. composite, single wall vs. double wall

. Pipe mechanical properties against the external and internal loading including stiffness and service/bursting pressure, and working temperature during lifetime of project

. Pipe safety and health criteria

. Pipe fittings, installation and handling

There are baseline standards in the BC Building Code (2018), and we select the piping systems based on the conditions and needs in any project. With 25 years of experience in waterworks, stormwater, drainage, sanitary, and having understanding about pipes technologies , we do this process accurately.

The filter design around the drain tiles or in any drainage system is a very important task in our designing process. We normally cope with following questions?

• Organic, synthetic, sand, gravel and what gradation and dimension should we consider?
• What kind of textile filter and what specification? Non-woven or woven textile? Should we use the common landscape mat?
• How should we deal with fine soils (clay and silt) migration toward the drain line? what about the plant root penetration?
• How to design to have a desirable operation and maintenance? Not clogging and blockage mess.

Any project has it’s dedicated design and criteria for the drains’ filter that should be addressed by designer.
