Consideration of renewal of contract to Building Crafts, Inc. for collector well cleaning services for the Environmental Services Division of Public Works.

________________________________________________________________________________
Summary: On May 26, 2017, two (2) bids were received for collector well cleaning services. These services include the cleaning and rehabilitation of lateral well screens, performance of pre-and post-maintenance pumping tests and disinfection of the collector wells that are part of the water production process. The initial two-year term of this contract was competed in 2018 and had the option for a two-year contract extension. This renewal includes the cleaning of Collector well #3 in 2019 and Collector well #2 in 2020.
Collector well #3 and Collector Well #2 have experienced a decline in capacity of 26% and 27%, respectively, since they were cleaned in 2013 and 2012. Industry practice is to clean these types of wells when the capacity has declined 20% to minimize permanent capacity reduction and maximize the life of infrastructure. Cleaning one collector well per year from 2017 through 2020 was planned for in the Water Production budget based on the speed of decline that triggered the previous round of well cleanings.
Twenty-two (22) vendors were notified of this bid. There are no local vendors who provide this type of service.
