Sprinkler, irrigation & drainage services in Holly Springs, NC

Holly Springs offers a dedicated irrigation meter, so water that goes on your lawn is not billed for sewer — a real, recurring saving we help homeowners capture when we install or rework systems. West of N.C. 55, some areas irrigate on reclaimed water, which clogs nozzles faster and needs proper line separation. The town runs its own backflow-prevention program, with test results filed through BSI Online — the same system Fuquay-Varina uses, so the paperwork will look familiar if you moved from there. Reclaimed-only systems are the exception worth knowing: with no potable connection to protect, they need no backflow preventer at all.

Holly Springs also stages drinking-water irrigation limits, and the trigger is not local. The town buys its water from Harnett Regional and follows Harnett’s declarations, so when Harnett County announces a shortage alert, Holly Springs follows within days. Watching Harnett news gives you roughly half a week of warning that nobody else in the county gets.

Stage 1 is tighter here than in neighbouring towns because it restricts hours as well as days: even-numbered addresses Monday, Wednesday and Saturday, odd-numbered Tuesday, Thursday and Sunday, and only between 6 and 10 in the morning or 6 and 10 in the evening. Nobody irrigates Friday. Hand watering, drip and reclaimed systems stay exempt. New landscaping can apply for a 30-day exception — note thirty, not the forty-five that Cary and Fuquay-Varina allow. Eight hours a day across three days is a genuine programming problem, and it is the point at which a smart controller stops being a luxury.

The numbers behind the reclaimed option are worth seeing side by side, because they are unusually clear here. Reclaimed irrigation is billed at the same rate as the lowest potable tier on a lower monthly access charge — and it carries no sewer charge at all, where potable irrigation adds a flat sewer rate on every thousand gallons that lands on your lawn. Over a Triangle summer on an established yard, that difference is not a rounding error. Where reclaimed is not available, the town’s dedicated irrigation meter achieves the same thing on potable water: billed as water, never as sewer.

On backflow, the practical detail is the notice. A letter goes out roughly thirty days before your certification falls due, you hire your own certified tester rather than one the town appoints, and the result is filed to BSI Online. Thirty days is enough time if you act on the letter and not enough if it sits on the counter — most of the panicked calls we get in Holly Springs are from people who found the notice a week late.

Looking further out, Holly Springs’ supply picture should improve. A 2025 change in state law removed a permitting obstacle to moving water between subbasins within the Cape Fear basin, which clears the way for a planned regional conveyance line serving Holly Springs, Fuquay-Varina and Sanford. It changes nothing about how you water this year. It does mean the restriction pattern of the last few summers is a phase rather than a permanent condition.

The soil is tight clay, and most of the housing is new enough that yards are still settling — which means heads drift out of level and low spots appear years after the sod went down.
