The 404 WaTerra Pump is ideal for dedication. The system includes a simple footvalve and length of polyethylene tubing, which is very inexpensive. Sampling to depths of 100 ft (30 m) can be performed by hand, or with the inexpensive hand pump handle, and to 250 ft (75 m) with an electric or gasoline pump controller. The Waterra Pump is suitable for purging, sampling and developing wells. It easily handles heavily laden, silty water. A variety of footvalve sizes, surge blocks, filters and 4 tubing sizes are available.
