Partners in Development (Pty) Ltd (PID) was established by David Still in April 1993. From a home-based business, PID has grown into an engineering consultancy which employs many people and contributes to projects on a local and national scale. PID has provided planning, design, training and construction management services on over 200 infrastructure projects to date. The majority of these have been in the rural water supply and sanitation field, but they have also included roads, sports facilities, township services, agricultural infrastructure, school sanitation, and the management of several major community-based domestic sanitation projects. In all projects the use of labour has been maximised and managed according to the principles of labour-based construction. Through consulting and research, PID is able to share knowledge and lessons-learned both nationally and internationally. PID also manufactures the PITVAQ pit emptying machine. The PITVAQ is the "honeysucker that can go anywhere", providing emptying teams power, efficiency, and flexibility. Learn more at our website: www.pitvaq.com.
