Design of Bandhara / Weir Dam gates using plastic materials_Design Directions_2010
The document discusses the design and management of K.T. Weir micro irrigation dams in India, highlighting issues such as theft, rusting, and ineffective designs currently in use. The objective is to innovate by creating more durable, lightweight, and attractive gate designs that are easy to install and have low resale value. A prototype using rotomolded materials is mentioned as a potential solution to enhance performance and reliability.

- 4. Managing Innovations Current scenario: •Govt Of India puts in lot of investment to build the micro dams such that farmers can get water for irrigation post the monsoon season and till the onset of next rains • Most of the gates get stolen (As MS has a good resale value) or they rust with in 2 to 3 years – there by loss to the Government and the farmers. • Max height of these dams is 5 mts. • These gates are removed just before monsoon and reinstalled after the season is over. Thus prone to theft in this period • Each gate is 2000 mm X 500 mm X 4 mm thick MS Plates • Weight of each gate is @ 84 Kgs • Very heavy and cumbersome to install • Prone to water leakage due to use of an old and faulty design Copyright 2010 4

Managing Innovations Objective: • To design the K T weir gates in a material which would last longer • Should be easy to install and idiot proof • Should have less value for resale • Should be available at a right price point • Should look interesting and attractive • Should instill confidence that the gates will work as desired Copyright 2010 5
