Innovative Water Treatment System at Burke MountainSeptember 18, 2018 / in News, Residential
Wesbild’s new state of the art water retention and chemical treatment system is now installed for use on our construction sites! After months of hard work collaborating with Port Moody-based Aquasolve, this new system replaces our previous water treatment strategy of excavating and constructing a large sediment pond.
How Does It Work?
First, the dirty storm water run-off is collected in a large steel container. Once the water reaches a certain level, a sensor tells a Programmable Logic Controller (an industrial digital computer) to pump the dirty water into a separate treatment tank for pH testing and chemical treatment. Once this is done, the water is sent into a smaller tank which allows for the chemicals to properly bond with the water. This tank also allows for heavy solids to be sifted out of the water. Next, a sensor triggers the system to pump the water through a series of sand filters to further clean the water. For good measure, the water is sent back into the treatment tank for another pH test. If the results satisfy the acceptable discharge levels, it is pumped out of the system into a storm drain.
One of the best features of this new system is its ability to be monitored in real time. Throughout this entire process, the Programmable Logic Controller allows for the system to be remotely monitored. In the rare event that something goes wrong, Wesbild and our Environmental consultant, and the City of Coquitlam will be alerted right away, and we can promptly act to fix the problem. Using this new system effectively ensures our site will remain in compliance with the bylaw during construction.
A Wesbild Commitment
Wesbild has always been committed to environmentally responsible
development, and water treatment plays a huge role in that. The system was designed over months of research and testing, and can be disassembled and reinstalled on future development sites. With this new system, Wesbild is confident our water treatment has thoroughly improved, and we look forward to its continued use at Burke Mountain.
