Design, Collection and Storage Systems
There are plenty of consultants who advise on winery wastewater, but there are very few who specialize in harvesting rain like Climate Inc. With today’s water issues–primarily availability–a winery might start considering using free rain for its crush pad, processing, barrel washing or irrigation strategies.
Consider the fact that only 1,000 square feet of roof area from a one-inch storm will yield roughly 600 gallons of pure, mineral-free, pH-neutral, non-eroding water that would otherwise be destined for a drain or stream bed. A 50-by-100-foot roof, in the same rain event, yields approximately 3,000 gallons of water.
In a 15-inch rain season, that is almost 45,000 gallons of free water. An efficient winery now uses roughly three gallons of water to produce a gallon of wine. These 45,000 gallons factor nicely for a 15,000-case winery.
Climate Inc. is a single source company, from consulting to design, installation and maintenance services, including code compliance and engineering. We offer wineries the means to fill these tanks by harvesting free water from the sky. Existing wineries are usually on a well with a tank (consider your water quality), so adding back-up rain collection to augment that system would be fairly easy. For new construction, the design possibilities can be impressive but require more preparation.
Commercial rainwater harvesting systems are attractive because they help meet water supply and water management needs effectively while also addressing environmental concerns. Any development that has a large roof combined with a high use of non-potable water (landscaping, water features, toilets, etc.) can use a rainwater harvesting system effectively. When available incentives are factored in, payback of capital costs may occur in less than 3 – 4 years.
The components are the same for commercial properties, large buildings, resorts and shopping centers – anywhere there is significant roof exposure. Consequently, most rainwater harvesting systems are custom engineered to the building and its landscaping plan. The development of an appropriate commercial rainwater harvesting plan involves three phases:
Site engineering: Draw the natural drainage paths, their highs and lows. Identify natural catchment areas, and determine how planned landscaping will alter the terrain and flow. Design the means to move the water from catch areas to planting, for example, through gravity or pump pressure.
Demand calculation: The first rule in rainwater harvesting is the amount of water collected and stored must equal or exceed the winery’s demand. Climate Inc. can help with “sizing” the total system, factoring roof square footage, inches of rain and recovery rate (normally 95 percent efficiency), all of which will help determine storage tank size and filtration requirements. Rainwater is not dependable, so it is important to know how much you can rely on the catchment and on the utility water supply.
Construction: Design and implementation of a new construction is easier than adapting an existing site. An existing site needs retrofitting, but new sites can match plant placement and thirst to the collection and distribution system.
