Handout 2E: Hydram training workshop participant site information

Hydram installations are extremely site specific. Although it's a simple technology, it does require being properly designed and sized based upon particular characteristics of the site. It also requires a certain amount of follow-up and maintenance. In order to maximize your learning during the workshop, please begin to gather the following information. (You don't have to have all of the information prior to the workshop, but it will help if you begin to consider these factors at your site.)

1. What water sources are available?

2. What kinds of water systems are presently being used? Who is responsible for maintaining the systems?

3. What are the present patterns of water use in your community? (e.g. potable water, irrigating home garden plots)

What is the proposed purpose for the hydram installation?

5. What kinds of skills and resources are presently available to support a hydram installation?

Community history of cooperative work on projects?

As existing community water distribution system?

Facilities and craftspeople in or near the community with metalworking, plumbing, and masonry capabilities? Vocational technical schools, public works?

6. How do you rate your present knowledge/experience about water systems, pumps, hydrams? What do you need to refresh, what do you need to know?

7. If you have a site in mind for a hydram, can you find out: a. approximate flow rate of the water source (gallons/minute) b. approximate "drive head," i.e., vertical distance from water source to where hydram will be installed? c. approximate "delivery head," i.e., vertical pumping distance from ram to point of delivery? d. amount of water desired/required? (gallons/day)

NOTE: During the workshop, you will learn simple measuring techniques; knowing this information beforehand allows one to design a site specific ram during the workshop with guidance from the training staff.

Please bring this sheet with you to the workshop. If it's easier to sketch your situation, feel free to do so.
