Our company supplied the equipment for the the installation an off grid rainwater harvesting system at an estate on the KwaZulu Natal south coast. The property has no municipal water connection and will rely in totality on rainwater as a source of potable water. The property has multiple buildings, roof shapes and levels. A system was designed where rainwater are harvested of multiple buildings into intermediate tanks and then transferred into a central tank storage system. Prior to the installation all gutters were upgraded From the central rainwater tank storage system, rainwater is treated on demand to potable standard and...

One of our customers purchased a WISY linear AK100 horizontal rainwater filter from us. He had limited space to install a primary rainwater filter in a down-pipe and applied a creative way to use the filter. The filter allows for a minimum height differential when installed and is very effective in harvesting and filtering rainwater at the same time . It can be painted to blend in with building. It is easy to access and clean and service.

Saradox factory in Durban South extended and increased the capacity of their rainwater system. Two new, inline WISY primary filters were installed in the 110mm gutter down-pipes. These units filter out any debris in the water before it is transferred to 20 000 liters  of rainwater tanks. The factory has increased the rainwater storage capacity to to 80 000 liters of rainwater. 50mm of rain now allows the factory to recover approximately 75000 liters of rainwater. All the rainwater is purified though a 5 stage filtration system and then used as process water in the factory. This extended rainwater harvesting...

Our installation team did a  40000l rainwater harvesting system for a factory in Durban. Rainwater is recovered off a 1100sqm roof and channelled down into two WISY WFF150 rainwater filters where the water is screened (all items bigger that 80 micron is removed) and the clean water is directed to the four 10000l interconnected tanks. The rainwater in the tanks are purified with our 4 step purification process and used a plant and process water.  The process water feeds the boilers and cooling systems and the plant water is used for manufacturing personal and homecare products .  Industrial water prices in Durban will increase by...

If you want build a good rainwater harvesting system that will deliver a good quality rainwater to your house or factory you have to include these 4 critical elements in your design 1. A good primary filter. This removes small organic items from the water before it enters the tank. There will be no sludge buildup in the tank and water quality will be superb. You can either install a downspout filter or a vortex filter. Filters are sized according to the size of the roof from where they will recover the rain water. 2. Low disturbance inflow. Designed to...
