When the Helix Water District received contractor estimates as high as $3.5 million to upgrade the R.M. Levy Water Treatment Plant’s ozone power supply units and generators, it decided to perform the upgrade in-house.
With Suez Water Technologies provided engineering and equipment, Helix employees incorporated new technology and innovative installation practices. The proof of concept pilot project proved the feasibility of the new approach, and a full retrofit is now planned. The estimated upgrade costs to complete the full project is $1.1 million – an approximately 70% cost savings. The upgrade will extend the life of the power supply units and generators at least 15 years.
