Capital projects to renew or replace water and wastewater distribution systems can save big on Greenhouse Gas (GHG) emissions when Cured in Place Pipe (CIPP) lining solutions are used in place of conventional open-cut trenching.
The Province of British Columbia, in partnership with the Union of British Columbia Municipalities and the Fraser Basin Council, has developed a toolkit to help BC communities meet the GHG reduction commitments in BC’s Climate Action Charter. The toolkit has been recently updated with a module that provides guidance for simple estimation of the amount of GHG emissions that can be saved when conventional open-cut water and wastewater capital projects are replaced with emissions-lowering trenchless technologies such as CIPP lining.
We have used the toolkit to compare GHG savings associated with CIPP rehabilitation of water and wastewater distribution systems versus open cut replacement and the results show an astounding reduction of 393 tonnes of CO2e (CO2 equivalents) linear kilometre of project. Additionally, by removing the need to haul earth, asphalt, and aggregates to and from the job site, CIPP projects can remove 570 trucks from the road per kilometre of project.
Over the past three years, CWW has rehabilitated and preserved an average of 60 km of wastewater systems each year. That’s a savings of over 23,500 tonnes of CO2e per year and 143 fewer trucks on the road each workday!
CWW works with Engineering Consultants and Municipalities across Ontario, Quebec, and Atlantic Canada to apply proven Trenchless Technologies in underground infrastructure rehabilitation. We are proud to deliver project solutions that simultaneously provide cost-savings, environmental benefits, and minimize road congestion in our communities.
