How to Get Recycled WaterObtaining recycled water

• The filling station is at our Household Hazardous Waste Collection Facility, 4797 Imhoff Place, Martinez, CA.

• Prior to using the station for the first time, you’ll need to complete an Application/Agreement form. You can download it by clicking here, or obtain one at the station. After turning in your form at the station, you’ll receive brief training (about 10 minutes) on the proper use of recycled water, and can then fill your containers. You will not have to pay a fee.

• Bring your own containers, which must be a minimum size of one gallon, made specifically to hold liquids, have watertight lids, and be secured for safe transport. If you’re considering buying a container and are not sure whether it will be appropriate for this use, give us a call before you make the purchase and we’ll help you decide.

The maximum fill per trip is 300 gallons. That does NOT necessarily mean it’s safe for you to transport that much water; it depends on your vehicle and its load capacity, which is your responsibility to know. Look for it on a label inside the driver door frame or in the owner’s manual. Safety first! 

• There is no limit on the number of trips.

Water is heavy! Ten gallons weigh more than 80 pounds; 100 gallons weigh more than 800 pounds. When driving vehicles with such heavy loads, expect less stability and be sure to allow for additional stopping distance.
