Determine the number of pumps needed and locations of well points. A pump test was conducted to evaluate hydrogeological information of the site, the hydraulic properties of soil and radius of influence. A fully penetrating well points with well radius of 3" was constructed and then another monitoring well was dug at a distance 50' from the center of the well. Both wells were 60' deep when both encountered tight formation of negligible permeability. Both well showed a static water-table of 10' below the surface. A well pump withdrawing 10 ft3/min resulted in drawdowns of 30' and 10' respectively at the well and monitoring location. Now you are supposed to use the above data to design a dewatering system for above the site. A building of footprint of 200'x200' to be constructed and requires 25' of depth without water to construct a basement. Assuming you have several well pumps withdrawing 10 ft3/min, Note that if you do not have symmetrical well arrangement, you need to plot contours within the building footprint show your design is acceptable for dewatering.
