Construction Water

The primary purpose of construction water is for on-site dust control and soil consolidation during construction and/or grading activities on lands within the District’s boundary.


  • Construction water may not be utilized outside of the District's boundary without the signed approval of the District's General Manager.
  • Construction water shall not be used for crop irrigation or watering of livestock.
  • Water from the gravity agricultural irrigation systemsis only available during the Board approved irrigation season, typically from March 1st through October 15th.
    • Typically this water must be pumped by the user from an open irrigation canal and is tracked by loads counts submitted weekly to the Engineer.
    • Access "driveways" from the county roadways to the delivery site must be temporarily improved and follow the guidelines and requirements from the CA Stormwater BMP Handbook - Construction and meet all other county requirements.
    • At the end of the contract, the District will require the improvements to be removed and the area returned to its pre-contract condition. 
  • Water from the pressurized non-potable water systemsmay be available during the agricultural off-season.
    • These systems have limited capacity and may require additional on-site facilities to be provided by the user such as drop tanks or other storage facilities.
    • This water is typically delivered to the user through an appropriate metering device provided by the District. If the District does not have the required meter available, an approved meter must be provided by the user and installed by the District for the duration of the Contract.
  • Water from the pressurized potable water systemsmay be available during the agricultural off-season.
    • These systems have very limited volume and will require additional on-site facilities to be provided by the user.
    • The flow capacity (i.e. gallons per minute or cubic feet per second) is also limited, the user may be restricted to lower delivery rates.
    • This water is typically delivered to the user through an appropriate metering device provided by the District. If the District does not have the required meter available, an approved meter must be provided by the user and installed by the District for the duration of the Contract.
  • Approved contracts cannot be transferred to another user even if the work being done is on the same parcel of land or within the same development area.
  • Approved contracts are terminated on December 31st of the current calendar year and must be resubmitted the following year if additional construction water is needed.
    • Multiple-year projects must pay for their "to-date" water usage, following year's water and renew their contract prior to receiving any additional construction water. This will be typically completed in January.
  • The unit cost for construction water and associated fees are recalculated annually and follow the Board approved current rate increase and structure.
  • Before completing the request form below, please ensure the date on the form matches the current calendar year to ensure the correct rate structure has been calculated.
