California Code, Water Code - WAT § 31701.7

In case any charges for water or other services, or either, remain unpaid the amount of the unpaid charges may in the discretion of the district be secured at any time by filing for record in the office of the county recorder of any county, a certificate specifying the amount of such charges and the name and address of the person liable therefor.

From the time of recordation of the certificate, the amount required to be paid together with interest and penalty constitutes a lien upon all real property in the county owned by the person or afterwards, and before the lien expires, acquired by him. The lien has the force, priority, and effect of a judgment lien and shall continue for 10 years from the date of the filing of the certificate unless sooner released or otherwise discharged. The lien may, within 10 years from the filing of the certificate or within 10 years from the date of the last extension of the lien in the manner herein provided, be extended by filing for record a new certificate in the office of the county recorder of any county and from the time of such filing the lien shall be extended to the real property in such county for 10 years unless sooner released or otherwise discharged.
