Summary
Letting delivered water leak or seep off your unincorporated San Diego County property is itself evidence of a code violation. The person in possession or control of the premises is presumed responsible, and violations run through the code's general misdemeanor penalty.
No person shall waste or cause or permit to be wasted any water furnished or delivered by any agency distributing for public benefit any water dedicated to or provided for public use within the unincorporated territory of the County of San Diego. ... It shall be prima facie evidence of the violation of this chapter for any person to permit any water supplied from such a source to the premises owned, occupied or controlled by such person to escape, flow or seep therefrom. ... The person actually or ostensibly in possession, control or ownership of any premises upon which water is wasted or permitted to be wasted in violation of this chapter shall be prima facie responsible for such violation.

Full Breakdown
103) prohibits wasting any water furnished or delivered by an agency distributing water for public benefit within the unincorporated territory. 102 does not require an inspector to catch water actively running; it makes seepage itself, meaning water from that supply escaping, flowing, or seeping from the premises, prima facie evidence that the chapter has been violated. 103 then places responsibility on whoever is actually or ostensibly in possession, control, or ownership of the premises where the waste occurred, so a landlord, tenant, or property manager can each be on the hook depending on who controls the site when the leak is found.
117: any code violation is a public nuisance, is punishable as a misdemeanor (up to a $1,000 fine and/or six months in County Jail) unless the code specifies an infraction, and each day the leak or waste continues is charged as a separate offense. ) for the physical fix once waste or seepage is identified.
Violations & Fines
Because Chapter 1 sets no chapter-specific fine, a wasted or leaking water violation is prosecuted under the code's default rule: a misdemeanor punishable by up to a $1,000 fine, up to six months in County Jail, or both, with the County and prosecuting agencies retaining discretion to charge it as a lesser infraction instead. Under Section 11.117 each day the seepage or waste continues counts as its own separate offense, and Section 11.111 independently classifies any violation as a public nuisance subject to abatement.
