Info

Crops and Productivity It was found that during the Kharif season, Bt cotton, juwar, pulses, vegetable, soybean, paddy and castor are grown using wastewater. In Rabi, wheat, fodder grass and alfa alfa are grown, where as in summer, crops like juwar, castor, alfa alfa, maize and Bajra are grown. Surprisingly, paddy is also grown in summer using wastewater, fetching higher market prices. As the landowners here do not cultivate land themselves and have large landholdings, it is leased to others for farming.

6 Wastewater Irrigation in Surroundings of Rajkot City Rajkot is the third largest city in Gujarat after Ahmedabad and Surat. Rajkot is the 23rd urban agglomeration in India, with a population more than 1.6 million as on 2012. It is the administrative headquarters of Rajkot District, 245 km from the state capital Gandhinagar, located on the banks of the Aji River and Nyari River. The city is spread over 170.00 km 2 History of Wastewater Use In Rajkot, there are informal level institutions, which have evolved around the use of sewage farming in form of two cooperatives. The first one is ‘Shri Sewage water Lift Irrigation Sahakari Mandali Limited’. There were 210 farmers, who were members and had a total of 280 ha land (700 acres). It was formed in 1962 and functioned till 2004. The cooperative used to pay Rajkot Municipal Corporation (RMC), Rs. 1000 to Rs.1200 per member for pumping per month per acre. RMC signed a Memorandum of Understanding (MoU) with the Cooperative for providing sewage water in lieu of fresh water from Lalpari pond, which was to be supplied to the city and this supply continues till this date. Some farmers did not wish to pay the monthly pumping cost as the new pipe line carrying sewage was next to their fields, hence the Cooperative ceased to exist. Currently, they breach the sewage-carrying pipe and irrigate their land. This Cooperative had a turnover of Rs. 4,30,000 in the year 1995-96. Another cooperative is ‘Shri Ramjino Valve Lift Irrigation Sahakari Mandali Limited’, which has 108 farmers as members owning 140 ha land (350 acres). It was formed in 1962 and is functional till date. It pays RMC Rs. 1000 to Rs.1200 for pumping per month per acre. The RMC signed a MoU with the Cooperative as well for providing sewage water in exchange of fresh water from Randerada pond. The city still receives fresh water from Randerada pond. The farmers receive Rabi irrigation from Lalpari lake, especially for wheat cultivation. Water Supply Situation The current water supply in the city is 225 MLD per day as per the information shared by RMC. 120 MLD of surface water is accessed through the city’s own source, which comprise various dams. These dams include Nyari 1 Dam with 32.3 MLD supply, Nyari 2 Dam with 10.6 MLD supply, Lalpari Randarda Dam with 2.9 MLD supply, Aji- 1 Dam with 30 MLD supply and Bhadar Dam with 45 MLD supply. The city also procures 105 MLD from Narmada supply. The RMC plans to enhance water supply by 20 MLD in next three years. Sewage Situation According to the information shared by the RMC, the available treatment capacity is low at 95.5 MLD. On account of considering 80 percent of water supplied as wastewater generated in a city, the wastewater in the Rajkot comes to 180 MLD. This 31
