July in Londonderry can go three weeks without real rain, and you can read it straight off the lawns — the low ground along Beaver Brook still green, the high sandy yards going straw-colored by the day. Scott'z Irrigation answers that with water put exactly where it belongs: sprinkler systems installed, heads adjusted and aimed off the pavement, startups in April and blowouts before the first hard freeze. Southern New Hampshire soil drains fast, so coverage and timing matter more than sheer volume. A well-set system is invisible — it runs at four in the morning and the grass never notices August. Come October it gets drained down and put away until spring.
