This prestigious award is a great endorsement of the settlement process of FERRER® in Canada and of the consortium of which it is part, HFNA. «The award is the recognition of a complex work well planned and executed», said HFNA partner and technical director, Alejandro Ferrer. «For HFNA it is gratifying to the extent that it reaches all the members of the team, both those who have acted directly on the design and execution as well as those who have participated with their indirect contributions such as management, organization and administration», added Ferrer.

‘The Dewatering Consultant Project of the Year’

HFNA submitted to the Award Winners 2023 of The Dewatering Institute the project for the implementation of a Wastewater Pumping Station (WWPS) in the town of Orillia, Ontario (Canada).

HFNA was contacted by contractor JB Enterprises to resolve the water table control issues that had forced the excavation of the WWTP to be put on hold for more than a year. HFNA’s technical management designed a Dewatering system based on 10 low-capacity deep wells, replacing other ineffective systems that would have been used by previous subcontractors.

The execution of the Dewatering work was completed in just 45 days despite numerous inconveniences. Examples of these were the low temperatures reached, reaching -20 °C, or the limited bearing capacity of the soil where the drilling machine was placed, which caused instability of the equipment. This soil, inside the enclosure confined by secant piles, had been filled as a working platform up to the level of the external roads.

In addition, and in the words of Alejandro Ferrer, «this ‘The Dewatering Consultant Project of the Year’ shows once again that any conclusion based on theory must always be tempered with experience; a project can be undertaken with confidence when the theoretical conclusions coincide with those of the experts, judgment and vice versa», said.

The Wastewater Pumping Station will allow the expansion and improvement of Orillia’s sewage systems. The previous WWTP was more than 90 years old and its capacity was insufficient for current needs.
