On-site Treatment Case Studies
Case Study: On-site Wastewater Treatment at Konzelmann Estate Winery
Konzelmann Estate Winery produces 40,000 cases per year. To accommodate an expansion of their operations they needed to upgrade their on-site wastewater treatment.
Through referrals from other wineries, Konzelmann identified and selected AMEC as their consultant. Originally, a lagoon system was considered, but the size of the lagoon would have required land currently planted with vines. They decided to investigate other options and a Segflo Recirculating Biotower with a raised leaching bed was selected. The total system capital cost was approximately $200,000 plus consulting fees.
Konzelmann’s peak daily wastewater generation was measured at 7,000 litres/day and total site treatment capacity, including the new Segflo system, is 9,600 litres/day. However, estimates of wastewater generation, based on the Ontario Building Code guidelines, indicated that their peak daily wastewater generation was greater than 10,000 litres/day. As a result, Provincial approval from the Ontario Ministry of Environment and Climate Change (MOECC) was required along with a Building Permit from Niagara Region. Konzelmann was able to negotiate with the Region and MOECC to issue the Building Permit prior to MOECC approval of the wastewater system to avoid delays with approval and allow for construction to begin.
As part of the approval process with the MOECC, Konzelmann was required to undertake detailed water use monitoring, wastewater sampling, and groundwater monitoring due to their close proximity to Lake Ontario.
Konzelmann spent two years designing the system and collecting monitoring data prior to submitting their application. Approval was granted six months from the submission of the application.
Case Study: On-site Wastewater Treatment at Greenlane Estate
Greenlane Estate Winery produced about 5,000 cases per year but were planning for significant growth. They were informed by the Region of Niagara that they would not be granted a permit for on-site wastewater holding tanks due to restrictions within the Ontario Building Code. Since Greenlane did not have a municipal sanitary service connection, they needed to install an on-site treatment system.
Due to the close proximity to Lake Ontario and the high water table on their property, sub-surface treatment was not feasible and above-ground systems would have been required. The quotes that Greenlane obtained for above-ground systems were prohibitively expensive and there were a number of other challenges that made their location less than ideal so they began looking for additional property to support expansion.
An appropriate site was found nearby and Greenlane began the process of installing an on-site treatment system. Greenlane decided to install a wetland biofilter system from Aqua Treatment Technologies based on recommendations from other wineries and relatively low capital cost.
The capital cost of the system, including consultant fees , was $150,000, and was sized to support growth of up to 12,000 cases per year based on industry averages. The winery’s estimated peak daily wastewater flow rate was below 10,000 litres per day, so the only approval required was from the Region of Niagara under the Ontario Building Code. Design, approval, and installation took 8 months from start to finish.
Case Study: On-site Wastewater Treatment at Henry of Pelham
Henry of Pelham produces approximately 100,000 cases per year. In order to stay in compliance as the winery grew, they needed a new on-site wastewater treatment solution. After engaging AMEC as a consultant, they decided to design and install a lagoon system. Lagoons represented a relatively low capital cost solution to treat high volumes of wastewater generated from the winery. In addition, due to the large size of the property, the lagoon footprint would not encroach on land reserved for vineyards.
The system consists of a holding tank, an aerator pond, and an evaporation pond. The total estimated capital cost was $250,000 plus consulting fees. Henry of Pelham is able to monitor and maintain the system with internal staff.
In addition to an ECA from MOECC for the lagoon system, several other permits and approvals were required including:
- Approval from the Niagara Escarpment Commission because the winery is within the Niagara Escarpment Protection Area.
- Approval from the City of St. Catharines and the Niagara Region Planning Department for construction because the winery is located within the St. Catharines District Planning Area.
- Approval from the Niagara Peninsula Conservation Authority as part of the City of St. Catharines approval process because of the presence of a surface waterway (a tributary to Richardson Creek) on the property.
System design, consultations with different agencies to coordinate approvals, and developing a complete submission took approximately 36 months. Approval was given in February 2015 after two full reviews by both the Niagara and Toronto MOECC offices.
