General Groundwater Withdrawal and Discharge There are many concerns surrounding groundwater withdrawal and discharge to public conveyance systems. These concerns include: • The potential environmental harm caused by groundwater withdrawal.• Potential damage to real property or impacts to the ROW due to ground subsidence.• Increased risk of Combined Sewer Overflow events.• Increased capacity concerns for public pipes that were not designed with capacity to convey groundwater.• Risk of untreated contamination discharged to water bodies of the State. • Risk of discharge that may cause or contribute to a prohibited discharge, a known or likely violation of state water quality standards in the receiving water, or a known or likely violation of the City’s municipal NPDES permit.Due to these concerns, the City encourages construction practices that eliminate groundwater discharge to the public conveyance system.‌ Permanent Groundwater Discharge The public drainage system and public combined sewer are designed with capacity to convey only stormwater, and stormwater combined with wastewater, respectively; neither was designed with capacity to convey perched, static, tidally influenced or hydraulically connected groundwater. In this regard, the City has determined the public drainage system to be capacity constrained when groundwater is discharged. Projects which propose to permanently discharge groundwater shall comply with Minimum Requirements for Flow Control – Peak Flow Control Standard, SMC Section 22.805.080{B}4.Contaminated groundwater, which is a prohibited discharge, shall not be discharged to Receiving Waters, either directly or indirectly via the public drainage system.‌ Temporary Groundwater Withdrawal and DischargeWhenever groundwater withdrawal is proposed, the plan for groundwater management shall be documented and meet all applicable City standards. For construction projects, all projects that are required to submit a Construction Stormwater Control Plan must address the temporary groundwater withdrawal and discharge for the project with the submittal requirements below. This Plan and plan narrative must adequately represent groundwater management for the project described in Element 12, Control Dewatering in the Stormwater Manual Volume 2 Construction Stormwater Control Technical Requirements (DR 2009-004). Construction related temporary discharges may be requi...
