| Abstract/Contents: | "Multi-Stream Rotational Spray Heads (MSRSHs) both alone and in combination with other products may offer significant improvements in Lower Quarter Distribution Uniformity (DULQ). In tentative results from an ongoing study, the authors report that for 97 stations at single-family residences in Southern Nevada, retrofitting traditional fixed pop-up sprays with MSRSHs improved uniformity by 0.18, a relative percent difference (improvement) of 45%. Additional products tested included a non-rotating, oscillating sprayhead (where a DULQ improvement of 0.18 was also observed) and in-stem flow control (where an improvement of 0.08 was observed). Combined products stratifications were performed as well with results included below. For all 185 sites covered in this study to date, the DULQ improvement was 0.16 (relative improvement of 40%). The results suggest that all the technologies tested do improve DU and in every comparison the results demonstrate statistically significant improvement versus traditional pop-ups. The extent to which water conservation, the ultimate goal for utilities, is practically realized when these improvements are combined with homeowner watering behaviors is still being evaluated at this time." |
