Drainage and Reclamation Institute of Pakistan (DRIP) was established in 1975 under PCRWR with the mandate to conduct research in drainage and reclamation of waterlogged and salt affected soils, irrigation scheduling, efficient irrigation water management, groundwater monitoring and management, desertification control, saline agriculture, soil and water quality analysis. DRIP has successfully introduced and installed tile drainage technology on 1120 hectares on waterlogged and salt affected soils with active farmer’s participation. The following are the specific objectives:
- Drainage and reclamation of water logged and saline lands
- Irrigation scheduling and crop water requirements
- Surface and ground water resources monitoring and management
- Desertification control, rainwater harvesting and saline agriculture
- Soil and water quality analysis
- Coordination and working relationship with NGOS’s/INGO’s/public and private departments in water sector
- Documentation and dissemination of research findings to farming community/end users

1. Tile Drainage Technology
DRIP is pioneer organization for introducing Tile Drainage Technology in Pakistan. DRIP has installed tile drainage units on 1121 hectares in Sindh with farmer’s participation. Due to the demonstration and positive outcomes of the above-mentioned units, many progressive farmers approached the institute for the drainage of their lands on a cost-sharing basis.
2. Salt Affected Soils and Their Reclamation
DRIP undertook a program of research to solve the problems of soil salinity/sodicity in the Lower Indus Basin. In this context, several research studies are carried out on salt affected soils and their reclamation. The objectives of this research program were (i) to evolve cost-effective methods of reclamation of salt-affected soils, and (ii) use of saline groundwater for crop production. The following research studies have broadly been covered under three methods of reclamation including (i) reclamation by organic/inorganic, physical, and cultural practices (ii) biological reclamation of saline-sodic soil, (iii) Irrigation practices effect on soil salinity (iv) Management of reclaimed land.
3. Groundwater Investigations and GIS Mapping
To identify the fresh groundwater pockets in Sindh, Electrical Resistivity Survey (ERS) has been used. Through this method, resistivity values are calculated to determine the geological information of substrata, groundwater quality and aquifer thickness. The groundwater quality is divided into four water quality zones: freshwater (EC<1.5 dS/m), marginal quality water (EC 1.6-2.5 dS/m), saline water (EC 2.6-4.0 dS/m) and highly saline water (EC >4 dS/m). The DRIP office has equipment called Terra Meter used for groundwater investigation. This office is providing consultancy to different public and private organizations for identification and demarcation of groundwater quality.
4. Research and Demonstration (R&D) Farm
The research activities at R&D farm (22 acres) of DRIP are focused on crop water requirement and water conservation techniques to enhance the water productivity. The farm has attractive orchards of Mango, Guava, Lemon, and Jujube. This office has conducted research on wheat, cotton, sugarcane and banana on raised beds, bed & furrow, ridges and disseminated to the farmers for broader adaptation.
5. Lysimeteric Studies
The Lysimeter is an experimental setup in which soil water relationship are studied under controlled conditions. Lysimeter name derived from a Greek word ‘Lysi’ meaning ‘Water’. There are 12 conventional type lysimeters, each measuring 3m x 3m x 5m. The farmers are applying the water to the crops without knowing the actual crop water requirement. To overcome this problem, the water requirements of the major crops namely wheat, cotton, sugarcane, rice, rapeseed-mustard, chili, sesame and sunflower have been determined through Lysimeter. The results and findings have been published and disseminated to the end users/farmers through farmer’s days.
6. Agro Meteorological Station
An agro-meteorological station was established in March 1986 at DRIP. Meteorological parameters such as temperature, relative humidity, pan-evaporation, wind velocity, wind direction, sunshine hours, precipitation, wet and dry bulb temperatures etc. are recorded and compiled on regular basis. Potential or reference evapotranspiration (ETo) are calculated on daily and hourly basis using Modified Penman equation. The data is shared with different research organizations and university students in pursuing their research work for Master or PhD degrees.
Field Research Station
The DRIP has established the Field Research Station comprising 200 acres at Khario Nara, Mithi. The station is located at Chailhar road about 12 km away in North of District Mithi. The research activities are desertification control, rainwater harvesting, saline agriculture, rangeland management, pitcher irrigation system and conjunctive use of rain and ground water. Two rainwater harvesting ponds, tube well and fish farm have been developed at Field Station, Mithi.
Rainwater Harvesting Ponds
Two rain water harvesting ponds (150ft x 150ft x 20ft) each in size have been developed in the farm. The storage capacity of each pond is 12742 m3 with 3,366,080 US gallons. Both ponds are providing with silt trap channel, animal reservoir and, water depth measuring gauge.
The tube well installed at 76 m depth with EC 9.0 dS/m under the PSDP project Combating Drought and Desertification in the Thar Desert. The same tube well is converted into solar under another PSDP project Exploration of Exploration of Groundwater Potential and Promotion of Interventions for Rainwater Harvesting and Biosaline Agriculture in Tharparkar Desert. The water obtained from the tube well is mainly used for saline agriculture and to supply water to the fish farm. This tube well also feed approximately 5000 livestock and 2000 population from surrounding 5 villages on daily basis.
Pitcher Irrigation System
The pitcher irrigation system is installed under the shed on an area of 30 x30 ft. Soil of the area is sandy in nature as well as very poor in organic matter and other fertility ingredients. Seasonal vegetables of different kinds are being grown on experimental basis and successful results are achieved.
Under saline agriculture, the salt tolerant crops/trees are grown through saline water at Field Station, Mith. Different fruit plants like jujube, Guava, Falsa, Jaman, Cheekoo, and lemon, and date Palm are grown at the Station
With the financial assistance of The Asia Foundation (TAF) a fish pond (60ft × 40ft x 7.5ft) is constructed under the project “Piloting Climate Smart Aquaculture in Tharparkar for Local Food Security” at Field Research Station, Mithi. The aim of the project is to promote food security options in Mithi, Tharparkar through aquaculture and effective use of land and water resources to the local community. About 40 fish fingerlings of different variety like Thaila, Silver carp are stocked into the Fish farm. The farm yard manure, fish feed and dry meal is applied in the pond to feed the fish fingerlings.

Sub-Regional Water Quality Laboratories
The Water Quality Laboratories of Karachi, Hyderabad, Badin and Shaheed Benazir Abad are also equipped with the state of the art facilities and are providing service to the public and private sectors, under the administrative control of DRIP.
Documentation and Dissemination
The drainage and reclamation technologies developed by DRIP have proved highly useful, to achieve a significant increase in the yield of crops and economic returns from the farms. Documentation and dissemination of research findings/results, in the form of brochures, booklets and documentaries to the farming community/end users, through farmer field days, expert field visits, seminars, workshops etc. is a regular activity of DRIP.
The Institute has a modest but a specialized library holding of about 4000 books, journals and technical reports on agriculture, irrigation, drainage, land reclamation and related fields. Domestic as well as foreign journals create an added interest. Bibliographies on land and water development are also available. The services of this library are also available to out door researchers and students.
The advisory services are provided to the concerned farmers/end users/beneficiaries/stake holders regarding crop water requirement, best water management practices, reclamation of water logged and saline soils, surface and ground water quality analysis.
