Where Lakewood's tap water comes from
Lakewood drinks surface water. Consolidated Mutual Maple Grove draws it from the Fairmount Reservoir, the Welton Reservoir, and the Smart Reservoir and treats it before it goes into the distribution system. After treatment the water is held in 11 storage tanks and reservoirs and pushed uphill by 7 pump facilities; that storage is the buffer that keeps taps running for a few hours after a pump or main fails.
What this means in an outage. Because the water is drawn from open surface sources, it has to be filtered and disinfected continuously. A plant problem therefore hits everyone at once, unlike a main break, which only dries up the blocks on either side of the damaged pipe.
What causes water outages and low pressure in Lakewood
Which failures hit Lakewood hardest follows from its weather, its housing stock and how it is supplied.
- Freezing weather. Lakewood sees about 163 days a year with a low at or below 32°F, and 52 days at or below 20°F. The coldest morning in the 2015 through 2025 record came on January 16, 2024. The longest stretch with highs that never rose above freezing ran 7 days, ending January 16, 2024. Frost pushes into shallow service lines first. Mains follow when the ground heaves and thaws, which is why break counts climb a day or two after the temperature swings.
- Storm-driven power loss. Thunderstorm wind, hail and tornado reports in Jefferson County number 203 since 2015. Pump stations and treatment plants that depend on Xcel Energy run on the electric grid, so a storm that downs power lines can lower water pressure even when no pipe is damaged.
- Damage from other crews. Water mains share the ground with gas, power and telecom lines, and a strike by any contractor can dry up a block in seconds.
- One-address problems. A closed valve, a meter swap or a failed regulator can leave a single house dry. Compare notes with a neighbor first; if they have water too, start with your own plumbing.

Lakewood boil water notices and EPA compliance record
EPA lists no health-based violations for Consolidated Mutual Maple Grove since 2015. It also lists 3 monitoring or reporting entries that are about paperwork rather than water quality, such as a missed sample or a late report.
Most recent entries, all monitoring or reporting:
- December 2016: A missed or late monitoring or reporting requirement (surface water treatment and turbidity) It is marked resolved.
- November 2016: A missed or late monitoring or reporting requirement (surface water treatment and turbidity) It is marked resolved.
| Type of violation | Health-based | Monitoring and other |
|---|---|---|
| Surface water treatment and turbidity | 0 | 3 |

A boil water notice in Lakewood is a separate thing from a violation. Denver Water issues one when pressure falls low enough for contamination to enter the pipes, after a main break is repaired, or when a routine test comes back positive. The Colorado Department of Public Health and Environment (CDPHE) oversees the process, and the notice stays until clean samples come back, usually a day or two after pressure returns.
What the lead tests and housing age say about Lakewood
The most recent 90th-percentile lead result filed for Consolidated Mutual Maple Grove is 5 ppb (2025). The federal action level is 15 ppb, so that result is far from the limit.
Highest result on file: 14.4 ppb. Source: EPA SDWIS.
The age of the housing matters more than the utility's test average: 34.2% of occupied homes in Lakewood predate 1970 and 1986 was the year lead pipe and solder were banned. Flush the cold tap after an outage and ask Denver Water whether your service line is on its lead inventory.
When will the water come back on in Lakewood?
A crew that arrives at an ordinary main break in Lakewood usually needs 4 to 8 hours to isolate the pipe, dig, repair, flush and restore pressure. Large transmission mains, deep pipes and breaks under busy streets can take a day or more.
| Situation | Typical time |
|---|---|
| Planned shutoff | Time window posted ahead; water often returns early |
| Ordinary main break | Roughly 4 to 8 working hours |
| Large or deep main | One to three days, longer if parts must be ordered |
| Low pressure after a pump or power failure | As long as the outage itself, plus a few hours to refill tanks |
| Boil water notice after service returns | One to two days while samples are tested |
| Frozen service line or meter | Hours if you can thaw it, longer if the pipe has split |

Ask Denver Water for a restoration estimate when you report the outage; for large breaks it is normally posted and updated as the repair progresses.
Preparing for a long water outage in Lakewood
Census figures put the typical Lakewood household at about 2.2 people. At one gallon per person per day that is 7 gallons for three days or 31 gallons for a two-week supply.
- Do not forget the water heater: the tank holds roughly 30 to 50 gallons you can drink after it is switched off and allowed to cool.
- Fill the bathtub and a few large pots as soon as you hear a break is likely; that water is for flushing and washing, not drinking.

Lakewood water outage questions
Who do I call about no water in Lakewood?
Denver Water at 303-628-6801, day or night. Use 911 only if a main break is flooding property or roads.
Is Lakewood water from a river, lake or well?
Per EPA, the water system for Lakewood (Consolidated Mutual Maple Grove) is classed as surface water. It draws from the Fairmount Reservoir, the Welton Reservoir, and the Smart Reservoir.
Can you drink the tap water in Lakewood?
EPA lists no health-based violations for Consolidated Mutual Maple Grove since 2015, and its latest 90th-percentile lead result is 5 ppb against the 15 ppb action level. Follow any boil water notice until the utility says it is over.
When is water main break season in Lakewood?
Winter, mostly. Lakewood sees roughly 163 days a year at or below freezing, and the peak runs December through February. Expect breaks to cluster just after sharp temperature swings.
Why did the water pressure drop at my house in Lakewood?
Low pressure often comes from a nearby main break, heavy demand on a hot evening, or a failed pressure regulator at your own home. If neighbors are affected too, report it to Denver Water; if only your home is, check the regulator and shutoff valve.
How long does a boil water notice last in Lakewood?
Typically a day or two. Bacteria tests take about 24 hours, so Denver Water cannot end a notice until clean samples come back; the Colorado Department of Public Health and Environment (CDPHE) sets the rules for that process.
How many gallons of emergency water does a Lakewood family need?
One gallon per person per day is the FEMA minimum. For Lakewood that means about 7 gallons to cover three days for an average household of 2.2, and 31 gallons for two weeks.
Should I worry about lead in Lakewood water?
Lead pipe was legal until 1986, and 34.2% of occupied homes in Lakewood predate 1970, so it is possible in older neighborhoods. Denver Water can tell you what your service line is made of; a lead-certified filter is a sensible precaution if you are unsure.
