WISY our global partner recently launched the WISY AR100 inline filter. The filter has been designed on the WISY rainwater filtration principles and was extensively tested in various application before launch.

The space-saving LineAr 100 rainwater filter has been designed to specifically filter rainwater from within a rainwater tank - requiring minimal differential height. There are just five centimeters height difference between the rainwater inlet and the dirty water outlet. Thanks to this minimal height difference, the LineAr 100 rainwater filter is extremely easy to integrate into existing pipework. It can even be placed directly inside a rainwater storage tank without changing the gradient of existing piping.

WISY‘s LineAr 100 Rainwater Filter has a vertical filter mesh. Leaves, moss and other suspended particles are simply flushed past the filter into the drain outlet. This is the crucial advantage of this design over filter surfaces that are almost horizontal and become clogged with dirt very quickly. These are commonly found in other products. The pipe diameter is uniform throughout the LineAr 100 Rainwater Filter. Even a tennis ball washed off the roof by rain can pass unhindered through the filter housing.

The LineAr 100 Rainwater Filter is a rugged unit with a filter unit made of stainless steel. It has no wearing or moving parts that could impair reliable operation. We are pleased to offer a 5-year guarantee.AR100 Flush system

Our company designed and installed an integrated rainwater harvesting system for a house in Westbrook. The system was integrated into the design of the house. Our client required a system that would provide potable quality rainwater as well as a backup volume of water in case of water interruptions. It was also required for the system to boost the water pressure to the house.

The system consists of two interconnected 5000l rainwater tanks that store harvested rainwater. The total roof surface of the house is used for harvesting the rainwater.  Prior to entering the tank all rainwater is filtered with a WISY primary rainwater filter. The rainwater tanks also act as backup water tanks.  If the level in the tanks drop below 10%,  a solenoid top up system tops up the tanks to ensure the tank always have water. A booster pump with a water purification unit supplies water to the property at about 4-5 bar. The system is compact and energy efficient. A backflow prevention valve isolates the water system in the property from  the municipal water connection preventing any of the property's rainwater from entering the municipal supply while allowing municipal water to enter the property safely.

Zimbali Rainwater system

Our company was  commissioned  to design and install a rainwater harvesting system in one of the luxury homes  in Zimbali Eco estate, Ballito.  The design was completed in the early stages of the development and our team worked with the architects, project managers and plumbing contractors to produce rainwater harvesting system tailored to the households needs. The system was designed to fit into the cellar of the new house.

Water from the roof of the building is fed into a Wisy® WFF150 vortex filter where after it feeds into the first of two 5000 liter water tanks. A Wisy smoothing inlet, surface skimming overflow and floating suction are also used in the installation.The rainwater harvesting system is combined with a municipal back-up system to ensure that the water interruptions and pressure reductions do not affect this home.A Grundfos® CMBE3-62 multistage constant pressure pump supplies water to the household via a frame mounted filter set, ensuring all water has been treated and sterilized. The pump also supplies unfiltered water to the irrigation system.A backflow preventer valve was installed in the water supply line, to comply with estate rules and current legislation.

Our client requested us to install a backup water system at his guesthouse in Westville, Durban, Continuous water interruptions and low water pressure was having an affect on his guesthouse occupancy and affecting his business income.

As part of the water restriction program in Durban the Municipality has installed flow restrictors at the water mater to the property. The result is a drastic drop in water flow to a property. for bigger households it meant that if a shower water tap is opened the water pressure in other parts of the house dropped so low that water merely flowed out at a trickle from the tap.
