Applications

Municipal Rainwater Harvesting

Cities and municipalities can install the Optimax XXL as part of their stormwater management infrastructure. Its large flow capacity and self-cleaning technology make it ideal for public parks, sports fields, and civic facilities.

Commercial and Industrial Sites

Businesses with extensive roof areas or paved surfaces can significantly reduce potable water consumption by reusing filtered rainwater. Industries such as agriculture, manufacturing, and logistics can use harvested water for process needs, irrigation, and vehicle washing.

Environmental Projects

The Optimax XXL supports sustainable urban drainage systems (SUDS) and low-impact development (LID) strategies. By filtering and directing stormwater into infiltration basins or storage tanks, it reduces flooding risks and helps replenish groundwater.

Key Features

1. Advanced Filter Technology

The Optimax XXL uses a patented self-cleaning filter principle that separates debris and ensures the cleanest possible water output. Incoming rainwater is directed across a finely woven stainless-steel filter insert, which captures leaves, dirt, and other solids. The unique spray head system automatically flushes the filter clean during heavy rainfall, ensuring minimal clogging and maintenance.

2. Spray Head Cleaning System

RainHarvest’s product page highlights the chamber’s integrated spray head system. Four powerful nozzles deliver high-pressure jets that sweep the filter insert and chamber squeaky clean, flushing debris toward the dirty-water outlet and away from the system. This means longer service intervals and more consistent water quality.

3. 95% Water Yield

With such a high water yield, the Optimax XXL ensures that almost every drop of rainwater is captured and available for reuse. This level of efficiency sets it apart from standard rainwater filters and makes it an ideal solution for large projects where every litre counts.

4. Built for Canadian Conditions

The Optimax XXL is made from UV-stabilized materials and built to withstand extreme temperature fluctuations common across Canada and North America. Its design protects the filter from freezing in colder months and ensures dependable performance year-round.

5. Large-Scale Flow Capacity

This industrial filter can handle large roof and surface drainage areas, making it suitable for factories, warehouses, sports facilities, municipal buildings, and commercial developments.
