Their pricing is reasonable. Overall, they are very knowledgeable not only about wastewater, but specifically in our part of the state where smaller systems are more spread out compared to some of the more densely populated areas.”

“We asked CP Engineers to inspect more than 60 water main crossings and recommend upgrades. These inspections helped us identify potential system improvements, which enabled us to provide enhanced service reliability for large customer groups as well as critical infrastructure serving hospitals and schools.  CP performed the inspections and documented them in clear reports which included drawings and photos so that the upgrades could be prioritized and implemented.  We have engaged CP Engineers on numerous inspection projects.  They have shown that they are committed to our success and we can confidently recommend CP Engineers for their inspection services.”
