Regional Office, Tandojam
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, groundwater resources development and management, soil and water management and other related aspects. DRIP has successfully introduced tile drainage technology amongst the progressive farmers, for reclamation of waterlogged and salt affected soils with farmers’ participation in capital and responsibility, of the operation and maintenance expenditures. Similarly, the farmers have benefited from skimming well technology, by augmenting irrigation supplies, by pumping freshwater floating over native saline groundwater. Monitoring and evaluation of installed drainage projects has generated scientific data, for planning of future drainage projects. It has state of the art automated lysimeter research station to conduct various water management studies. Documentation and dissemination of research findings/results to the farming community/end users is also a regular activity of the Centre.
- Drainage of agricultural waterlogged lands.
- Salinity control and land reclamation.
- Crop water requirements, irrigation practices and water management.
- Irrigation and drainage modeling.
- Drinking water quality monitoring.
- Control on groundwater exploitation and deterioration.
- Introduction of efficient technologies for water resources development and management in southern Indus Plain.
- Water resources management in coastal areas, to monitor and check sea water intrusion.
Soil and Water Quality Laboratory of DRIP
The Soil and Water Quality Laboratory has been equipped with the latest instruments/equipment and qualified trained staff to carry out analysis. The water quality laboratory is equipped with water testing facility of the following important parameters:
Physical Parameters: Colour, Odour, Taste, pH, Turbidity and Total Suspended Solids (TSS).
Chemical Parameters: Alkalinity, Ammonia, Bicarbonate, Calcium, Carbonate, COD, BOD, Chloride, Total Dissolved Solids (TDS)/Conductivity, Nitrate, Nitrite, Phosphate, Free Chlorine, Hardness, DO, Total Chlorine, Sulphate, Sodium, and Potassium.
Trace Elements: Arsenic, Copper, Fluoride, Iron, Lead, Manganese and Zinc.
Microbiological Parameters: Coliform and E.coli.
Soil Parameters: ECe, pH, CO3, HCO3, Cl, SO4, Ca+Mg, Na, K, SAR, ESP, soil textural analysis (relative percentage of sand, silt and clay particles).
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.
Research and Experimental Farm
The DRIP has established a research farm on 25 acres of land which is located at Tando Jam; about 18 kilometers in the east of Hyderabad. The DRIP research farm has mild weather and low rainfall. The source of irrigation is skimming well and canal. A single bore skimming well at DRC Campus has been installed. The tapped water is used for irrigation of the experimental crops, as well as serves the drinking needs of the staff colony and office block. Twenty three piezometers have been installed at different depths and locations to monitor hydraulic gradient, radius of influence and the groundwater quality etc. The farm has a piped irrigation network and lined watercourses. Irrigation techniques such as trickle and sprinkler, bed and furrow, basin and flood are being evaluated on wheat, cotton, sugarcane, mango, ber, lemon and guava.
The DRIP Campus has a state of the art lysimeter research station which was made leakage proof by bitumen coating. It consists of 12 conventional type lysimeters, each measuring 3m x 3m x 5m. and provided with filter screens, non calcareous spawls and graded gravel filter material, drainage outlet and water feeding arrangements. For the artificial maintenance of different water table depths, Mariotte graduated bottles are used on all the lysimeters. To ascertain the desired watertable depths, each lysimeter is provided with a pressure meter and a manometer for counter check of watertable depths. The drainage effluent is collected in containers for measurement.
Agro Meteorological Station
An agro-meteorological station was established in March 1986 at the Institute. 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 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 following consultancies and services are provided to both the public and private sectors:
- Survey, design, installation and operation of tile drainage systems.
- Survey, design and construction of rainwater harvesting systems.
- Water quality testing/advisory (drinking, irrigation and wastewater).
