Rain Water Harvesting (RWH)

We are Manufacturer, Supplier, Exporter of Raintap Pop Up Filters and Our setup is situated in Pune, Maharashtra, India.

RainWater collected on the roof is very pure and clean. However, there are many substances, which get mixed with this pure Water on the roof (leaves, bird droppings, dust etc). These impurities need to be filtered before the rainWater is stored. RAINTAPTM Popup Filter is a simple device, which is very effective and user friendly. This filter has been successfully installed in many residential and smaller institutional or industrial buildings. This RAINTAPTM Popup Filter is simple in design and is flexible to install in varying field conditions.
An important feature in filtering rainWater is the separation of the first flush of rainWater from the relatively cleaner and purer subsequent rain.

In a building, rainWater is normally allowed to flow down from the roof through pipes. These pipes may be of PVC, asbestos, cement, cast iron, galvanized iron etc. However, PVC pipes are commonly used in the present times. They are cost effective and convenient for installation. RAINTAPTM Popup Filter can be installed to any of the above pipes with suitable inlet and outlet fixtures or fittings.

To grout the filter on the ground, two masonry supports are recommended to be constructed using brick below the filter. Make sure the brick supports are not below the flush cap (the flush cap need to be opened time and again) with one clamp holding filter on to the wall and two masonry supports from the bottom, the filter is rigidly fixed on the ground and wall.

Filter element
Filter element is made of plastic net and mesh to effectively filter rainWater from the roof of a building. A cap holder facilitates installation of the filter element inside the filter body and also positions the filter element at appropriate height inside the filter body. While removing the filter element from the filter, gently pull the cap-holder with its handle vertically upwards. Make sure the entire length of the filter element is pulled out of the filter before tilting. While installing the filter element back into its position, make sure the mesh role enters the barrel without any crinkle.
Gently push the filter element downwards up till the cap-holder sits and positions itself on the vertical column of the filter. The vent hole provided on the cap-holder of the filter element has to face away from the wall. This will facilitate flow of Water away from the wall in case the filter is clogged.

How RAINTAP^TM Popup Filter works ?
The RAINTAP^TM Popup Filter has three components (rainWater receptor, flush valve and filter element). RainWater receptor is where the rainWater is allowed to flow from the down pipes into the filter and a flush valve is provided to flush the first flow of the rain-Water along with leaves, dust etc. Water received in the receptor flows upwards against gravity through filter element to filter most of the floating matter and allow Water to sta-bilize in the filtration zone. RainWater passing through this filter element is relatively cleaner and flows through an outlet, which can be led to storage device.

Maintenance of Filter
Flush the first rainWater by opening the flush valve on the filter for few minutes, close the flush valve after all the dirt on the roof is flushed out and when cleaner Water starts flowing. When the rain stops, flush the filter and remove the filter cartridge gently from its place and wash it thoroughly under a running tap by gently tapping the filter element with a stick on all sides. The dirt sticking in the filter element gets released and washes off. Replace the clean filter element back to its place by gently inserting it in the vertical barrel. Take care not to press it too hard at the end. If pressed too hard, filter element gets locked inside the barrel and may require greater force to retrieve it back when required for subsequent cleaning and also may not function properly.
