Claim 8:
9. A system comprising:
a pump mechanism having an inlet side and an outlet side, wherein the inlet side is configured to fluidly couple to a fluid supply;
a pressure sensor operably coupled to the outlet side and configured to measure a fluid pressure at the outlet side;
an actuator mechanically coupled to the pump mechanism to drive the pump mechanism;
a controller coupled to the pressure sensor, wherein
the controller is configured with a preselected set of fluid pressure set points and one or more preselected sets of fluid flow rates, wherein the preselected set of fluid pressure set points comprises an ordered set of fluid pressure set points, the preselected set of fluid flow rates comprises an ordered set of fluid flow rates, and the controller is further configured to:
control the actuator to increase a fluid flow rate to a first flow rate in the preselected set of fluid flow rates when the fluid pressure at the outlet side falls to a lower one of corresponding fluid pressure set point in the preselected set of fluid pressure set points;
control the actuator to reduce the fluid flow rate to a second fluid flow rate in the preselected set of fluid flow rates when the fluid pressure at the outlet side rises to an upper one of corresponding fluid pressure set point in the preselected set of fluid pressure set points;

a sponge wherein the sponge comprises perforations; and
a low-flow device coupled to the sponge, the sponge fluidly coupled to the outlet side and wherein the low-flow device comprises a perforated tube with perforations about the perforated tube onto which perforations of the sponge are coupled and wherein the sponge is configured to dispense fluid through the perforations of the sponge, through the sponge perpendicular to a surface of the sponge; and a flow valve configured to deliver a flow rate of the fluid adjustable to any value within a preselected range from about 0.01 gpm to about 2.5 gpm, and wherein the first flow rate is less than about 2.5 gpm.
