Cross-connection engineering THE DARSPEC APPROACH: KNOWLEDGE, EXPERTISE AND EFFICIENCY Backflow prevention is an engineering discipline specializing in averting the flow of undesirable, often toxic or unsanitary water, in a plumbing system where it can potentially contaminate the drinking water supply. Proper installation of backflow prevention devices helps preserve drinking water from any possible contamination. We evaluate the building in its entirety and design a detailed strategy that guarantees complete legal compliance and is soundly integrated with external water supplies while respecting budgetary constraints related both to installation and maintenance down the road. What is cross-connection? CROSS-CONNECTION CONTROL PROGRAM Darspec designs safe water solutions for hospitals and clinics, industrial and commercial structures, agricultural facilities and institutional and residential buildings. Our engineering strategies keep water safe and secure for occupants and ensure all stakeholders that chemical or biological hazards do not enter the water supply. We make sure that the cross-connection control program we engineer operate on the right side of law and respect community standards. Darspec loves to meet with on-site personnel who know the building they work in like the back of their hand. With their help and by adhering to strict health and safety standards, our engineers and technicians work together to uncover and identify all cross-connections. All Darspec experts are trained and certified to work in confined spaces. CROSS-CONNECTION AUDITS AND SITE VISITS FOR ALL TYPES OF BUILDINGS We begin with an analysis of the building’s function and purpose in order to identify sources of potential drinking water contamination and the riskiest cross-connections. Darspec’s initial assessment: Determines the best engineering practices: making sure the most appropriate backflow prevention devices are installed in the right places; Looks ahead to keep future costs associated with required annual inspections and maintenance low. A cross-connection control program is most successful when owners, property managers and support staff are in-the-know. That’s why we recommend beginning each project with a training session where we outline what will be done and why. CROSS-CONNECTION PLANS, SPECIFICATIONS AND CONSULTATION Since each backflow prevention devices has been built to suit a specific range of needs, installing the wrong device could present negative consequences for the plumbing system particularly with respect to water pressure. That’s why Darspec engineers provide clear and detailed plans, specs and instructions to make sure the right devices are installed in the right way from the get go. And for better results, take advantage of our services at an early stage of the project. SITE SUPERVISION: MAKING SURE THE JOB IS DONE RIGHT ON TIME AND WITHIN BUDGET Darspec engineers closely monitor the work of contractors during installation and bring their knowledge and field experience directly to the job site. They make sure contractors comply with laws, codes (such as B.64.10 in Canada) and are supplied with and understand the specifications and plans determined by the engineer. CROSS-CONNECTION ONGOING PROJECT MANAGEMENT Since a building’s use and capacity change over time and as new codes or industry standards are put into effect, an ongoing cross-connection management program is essential to make sure the program remains compliant with code and continues to protect building users and the local water supply. The installation of a new sprinkler system or swimming pool or even something seemingly insignificant like a new coffee machine, can present new potential backflow hazards that weren’t originally anticipated. Darspec offers training specifically designed to keep your knowledge up to date on the matter.
