Our Mission

The HMUA is committed to providing the community with safe, clean drinking water and quality wastewater management, while maintaining the highest standards of customer service.


The NJDEP has placed 14 counties encompassing the northern, central and northern coastal areas of New Jersey under a drought warning due to ongoing precipitation deficits and deteriorating water-supply conditions.  Sussex and Warren counties rely primarily on groundwater and have been included in the warning because groundwater in this area is rated as extremely dry while precipitation and stream flows are rated as severely dry.

 The DEP offers the following tips to reduce water use:

    • At this time of year, it is appropriate to let your lawns go dormant.
    • Turn sprinkler systems off automatic timers.
    • Use a hose with a hand-held nozzle to water flowers and shrubs, or let them go dormant.
    • Use a broom to sweep the sidewalk, rather than a hose.
    • Wash vehicles with a bucket and do not run the hose more than necessary, or use a commercial car wash that recycles water.
    • To save water at home, fix leaky faucets and pipes. Consider replacing your toilet with a low-flow version; this can save around 11,000 gallons per year.
    • Upgrade your showerhead to low-flow versions, which can save some 7,700 gallons per year.
    • Upgrade your faucets or install faucet aerators; this can save some 16,000 gallons per year.

Concerns about chromium in tap water? September 22, 2016

Recent media attention has brought to light concerns regarding potential negative health effects from drinking water containing chromium-6.  The HMUA takes potential impacts to public health very seriously and works to ensure that its water is in compliance with all Federal and State standards.  In NJ, the maximum allowable contaminant level for chromium is 0.1 milligrams per liter (mg/l) or 100 parts per billion (ppb). This includes all forms of chromium, including chromium-6. Information published by the USEPA regarding chromium and potential health effects can be found at:

The Federal and NJ State Primary and Secondary Drinking Water Standards (as of February 2005) are provided at:

Chromium data from various points in HMUA’s water system, reported by the laboratory to NJDEP as required, is available at:  Historically the HMUA’s laboratory testing results for chromium, including chromium-6, are well within the USEPA and NJDEP standards.

Drought Watch Issued - Voluntary Conservation Requested July 26, 2016

As a result of continued dry weather, the Department of Environmental Protection has issued a water supply drought watch for Northern and Central New Jersey, including the HMUA service area.

The DEP is urging residents to voluntarily conserve water.  At this time we seek voluntary cooperation to preserve existing supplies. The goal is to moderate demand should dry conditions persist.

The HMUA urges residents to be especially aware of the situation and use water more carefully, especially when it comes to lawn watering and other non-essential uses.  This is a request for voluntary conservation, and is not mandatory at this time.

 Some suggested water conservation tips include:

  • Do not over-water lawns and landscaping. Two times per week for 30 minutes in the morning or late evening typically is sufficient. Use a hose with a hand-held nozzle to water flowers and shrubs.
  • Avoid watering lawns and plants during the heat of the day, since much of this water will evaporate without helping the lawn.
  • Use a broom to sweep the sidewalk, rather than a hose.
  • To save water at home, fix leaky faucets and pipes.
  • Turn off the faucet while brushing teeth and shaving.
  • Run washing machines and dishwashers only when full.
