India is an agrarian country. Water management is of critical importance to Indian agriculture. While the irrigated area in the country has almost doubled since independence it is believed that the irrigated area can not exceed 50% of the cultivable area with the conventional methods of irrigation even if the irrigation potential is fully utilized. To address this judicious and improved methods / technologies for harnessing maximum benefits from available water resources to enhance crop productivity without affecting soil health. After detailed study of inter-ralationship among soil, water, crop, land terrain and agro climatic conditions. Paras design a suitable and economically viable system to deliver a measured quantity of water at the root zone of each plant at regular intervals, to ensure that the plants do not suffer from over or under watering. The system installed at the farmers field is commissioned and later training is imparted to the farmer, followed by regular service support. Through the continuous development efforts, PARAS made the drip irrigation system to suit all type of soils, crops and agro climatic conditions.

General Maintenance Guidelines for Filters
In order to get maximum efficiency and optimum result it is necessary to prevent emitter, mini sprinkler and laterals from clogging. Hence, filtration system is the heart of irrigation systems. Properly maintained filters will ensure maximum efficiency of irrigation systems, by avoiding clogging. Install the filter/s on properly constructed masonry or concrete platform. Connect all the assembly properly. Ensure that all the filter candles inside the sand/media filters are at their place before filling up the sand. If hydrocyclone is to be connected to sand filter, install air release valve at highest point of the fitting.

1. Maintenance of Hydrocyclone Filters
Hydrocyclone filter requires least maintenance by cleaning the dirt, inside the under flow chamber at daily interval. Flush the chamber by opening flush valve/cap or open the main valve, for thorough cleaning. Please note that hydrocyclone filter becomes ineffective once the dirt collection chamber is full. Always run the hydrocyclone filter at nominal operating pressure. Clean the dirt regularly. Excess pressure and/or uncleaned dirt chamber may lead to erosion of walls.


2. Maintenance of Sand / Media Filters
Sand filter is effective for removing organic heavy and inorganic contaminates. Over a period, the contaminants in water accumulate and clog pore space in the sand bed and thus reduce the efficiency of filter. Daily backwashing of your sand filter is very important. Backwashing is the processes in which water flow is reversed and sand bed is lifted and expanded allowing it to release the collected dirt. The dirt is then carried away through backwashing valve. Backwash flow should be adjusted properly, because excessive backwash flow will lead to removal of sand itself out of the filter and insufficient backwash flow will not clean the sand properly.

    Sequence of backwash operation
  • Step 1. Open the Backwash Valve.
  • Step 2. Close the Outlet Valve.
  • Step 3. Open the Bypass Valve.
  • Step 4. Close the Inlet Valve.

Please note that in semiautomatic and automatic backwash option. Opening and Closing of the valve is done at the same time.

The sand filter should also be cleaned regularly as follows
1) Open the lid of sand filter
2) Start the Backflush operation
3) Put your hand inside the sand filter and stir the sand thoroughly.
4) Allow all the water alongwith dirt to flow through the main hole of the sand filter.
5) Close the lid for normal operation.


Install the filter/s on properly constructed masonry or concrete platform. Connect all the assembly properly. Ensure that all the filter candles inside the sand/media filters are at their place before filling up the sand. If hydrocyclone is to be connected to sand filter, install air release valve at highest point of the fitting.


3. Maintenance of Screen Filter

Flushing at scheduled daily interval is necessary to maintain your screen filter. It is recommended to flush your screen filter, if pressure drops more than 0.5 Kg/cm2 (5 m at water head). The pressure difference can be observed by checking inlet and outlet pressure by using a single 3-way control valve. Flushing can be done by simple opening of the drain valve, allowing the force of water to flush the dirt out through drain valve. It is also necessary to clean the screen at regular interval. Procedure of cleaning is very simple, open the screen filter lid, remove the screen & clean it in flowing water by rubbing with cloth or soft nylon brush.
