1 MMSD Response to the July 2010 Storms

2 Summer 2010 Storms Large # reports of water in basementLarge # reports of water in basement –10,000+ –Some repeated July 15 and July 22July 15 and July 22 –Both surface and backups Damage to District facilitiesDamage to District facilities How can we reduce the risk of basement backups and SSO’s?How can we reduce the risk of basement backups and SSO’s?

3 MMSD Response Public meetingsPublic meetings Implementing two new pump stationsImplementing two new pump stations Repairs to MMSD facilitiesRepairs to MMSD facilities Private Property I/I ContractsPrivate Property I/I Contracts –Lateral inspection –Engineering Increased funding and overall program developmentIncreased funding and overall program development

4 Public Meetings Many public meetings throughout regionMany public meetings throughout region –Milwaukee –Shorewood –Whitefish Bay –Others Homeowners looking to MMSD and municipalities for solutionsHomeowners looking to MMSD and municipalities for solutions Recognition of difference between local systems and MMSDRecognition of difference between local systems and MMSD

5 2 New Pump Stations Once tunnel closed, increased risk for basement backupsOnce tunnel closed, increased risk for basement backups –Overflow point is a potential flow constraint –Reduce constraint, reduce risk of basement backups Identified 2 higher risk locationsIdentified 2 higher risk locations –Diversion Chamber at 59 th and Trenton –Northeast MIS NS03 Pump stations would function so no overflow constraintPump stations would function so no overflow constraint

6 59 th and Trenton Diversion Chamber Reduce risk of basement backups when tunnel gates closedReduce risk of basement backups when tunnel gates closed –Keeps Menomonee River from flowing back into MMSD system Provides benefit primarily to Wauwatosa and Milwaukee, and West AllisProvides benefit primarily to Wauwatosa and Milwaukee, and West Allis
