Larkspur's drinking water comes from three Town wells in the Denver Basin aquifers, operated under contract by Semocor, so homes on town water don't have a pump of their own. Areas of the 80118 ZIP outside town limits aren't covered by the Town system, and properties there with private wells can have a plumber test the pump, switch and tank. Call the number on this page to be connected with a local plumber in Larkspur.
What to expect when you call
This is a free referral service, not a plumbing company. The call puts you through to an independent local plumber who covers Larkspur. Say whether you're on town water or a well and what the water is doing. For a water emergency inside town limits, call Town Hall at (303) 681-2324 during business hours (9 a.m. to 5 p.m. weekdays) or Semocor, the contract operator, at (303) 681-2253 outside those hours.
On a private well, the plumber will check the breaker, switch, tank charge and pump draw. On town water, the focus is pressure readings, the regulator and the line from the meter.
What the cost depends on
- Whether the issue is on the Town side, a leak past the meter or private well equipment
- For wells: the failed part and how deep the pump sits
- Tank replacement
- Rural distances and access on larger lots
- Town permits for work inside town limits
Larkspur's well-fed water system
Larkspur is a small town in the East Plum Creek valley along I-25, about 11 miles south of Castle Rock and best known for the summer Colorado Renaissance Festival. Its Public Works Department runs the water and wastewater systems within town limits, overseen by a Water & Sewer Board, with the water system operated under contract by Semocor, Inc.
The water comes entirely from three groundwater wells in the Denver Basin Aquifer System: Denver 1, Arapahoe 2 and Arapahoe 3. It is not surface water. But those are municipal wells. A home inside town limits gets water through a meter and has no pump, pressure switch or tank to fail. A pressure problem there is a plumbing issue or a Town-side outage.
Outside town limits, the 80118 ZIP covers land the Town's pages don't address. If your property has a wellhead and a pressure tank, you own the whole well system, and the usual symptoms apply: no water, a switch that clicks rapidly, air in the lines or a pump that won't shut off.
Inside town limits, the Town, not Douglas County, handles building permits. The Town Building Department is at 8720 Spruce Mountain Road, and SAFEbuilt schedules inspections at 720-641-1956.
A quick checklist
- Confirm whether you're inside town limits and on town water
- On a well, read the tank gauge and check the pump breaker
- Check an outdoor faucet for flow
- Look for wet ground between the meter and the house
- Have records of past well work handy
