Niwot's water and sewer

Left Hand Water District has served parts of Boulder, Weld and Broomfield counties since 1960. Its supply includes Lefthand Creek, Colorado-Big Thompson water from Carter Lake and the Williamson Ditch, blended with water bought from Central Weld County Water District, Boulder and Longmont, and it's disinfected with chlorine. The district locates its lines only up to the meter pit; service lines beyond the pit are private. It keeps a service line inventory and takes calls at 303-530-4200 on weekdays.

Left Hand's cross-connection program follows Colorado Regulation 11. Commercial and high-risk properties must install and maintain backflow assemblies, testing is annual and the district schedules it through a third-party contractor, with the customer paying for testing and maintenance.

Niwot Sanitation District collects and treats wastewater at its own plant, covering about seven square miles. Under its rules, each user builds and maintains the entire sewer service line from the building drain to the main and must repair leaks or breaks after notice. Only the district or its representative may make connections to district lines, which matters for a new building or an addition. District emergencies go to 303-652-2525, press 1. The gas utility wasn't confirmed for Niwot, so check your gas bill.
