BACKGROUND The Abalone Cove Sewer System was installed and became operational in 2001.It serves residents of Abalone Cove in the landslide area.To insure a flow of funds for the on-going operation and maintenance of the sewer facilities in the Abalone Cove Area,the City Council formed the Abalone Cove Sewer maintenance Fee in July 2001.Funds to maintain the system are collected annually through property assessments. The Abalone Cove Sewer System consists of three sub-systems;a gravity system,a force main system and a low pressure system.The force main system needs repairs.It consists of four large pump stations where waste is pumped at a higher pressure to overcome elevation differences.The sewer pump stations were designed to operate using twin (or redundant)single phase pump motors.The two sewer pump stations that move the majority of waste material use 10.5 horsepower pump motors,the other two move a smaller amount of material and use redundant 7.5 horsepower pump motors.As previously stated,all the sewer pump stations were designed to run using the existing single phase electrical power. This power source has been problematic for the larger pump stations,ultimately leading to the need to replace the pumps and electrical control box.One of the large pump stations L-1 has been retrofitted with a three phase power converter,the required electrical control box and three phase pumps.The retrofitted pump station has not required service since it was put in service in 2009.Accordingly,Staff has determined that the remaining larger,single phase pump station should be retrofitted to a three phase system. DISCUSSION The pump station needing repairs is located at Abalone Cove on the south side of Palos Verdes Drive South.The pump station needs electrical or mechanical repairs approximately ev~ry four to six months and most recently one pump motor failed completely.The pump station is currently running on one pump motor without a back up.If the remaining pump fails it is likely to result in a sewage spill which can degrade the environment and subject the City to fines of up to $10,000 a day.To minimize the possibility of a complete system failure and mitig'ate this emergency,Staff has initiated replacement of the system components. Due to the immediate need to perform this work to replace the pump stations components, Staff is recommending that the City enter into a contract with Multi W Systems,Inc.to procure the required equipment,perform repairs,install the equipment that is necessary, and to enter into a contract with Multi W Systems,Inc.to re-establish a safe and operational sewer pump station.Multi W Systems has serviced the City's sewer pump stations, providing maintenance and performing repairs for several years.Prices for their services are consistently lower than competitors,Multi W Systems provided a proposal to remove the existing pumps,and control box,and to install the three phase electrical control box, power converter and pumps for an estimated cost of $44,220.97.In the event that additional work is needed,to minimize delays,Staff is also recommending approval of a project contingency in the amount of $1 ,779.03.Because of the benefits of addressing several different problems by doing all of this work at once,and the immediate need to provide a fully functional sewer pump station,Staff recommends that the City Council find by a 4/5 vote that an emergency exists,approve the agreement with Multi W Systems,Inc.,and authorize the Director of Public Works to execute the contract. ADDITIONAL INFORMATION Staff contacted another contractor that is qualified to perform the sewer pump station repairs to obtain an additional bid for the work.The contractor was unavailable to begin working on the project (due to a heavy work load)and could not accommodate the emergency time frame required by this project. CONCLUSION The City needs to repair the existing system to enhance the reliability of the sewer pump station and bring it back online as a fully functioning sewer pump station.Accordingly,Staff recommends that the City Council take the actions recommended by Staff. L-2 FISCAL IMPACT Funds for this project are available in the Abalone Cove Sewer Maintenance Program.The total cost of this project is estimated not to exceed to be $46,000.00.
