Renovation of a water / sewer project in Tacoma, Washington. Completed plans call for the renovation of a water / sewer project.

The City of Tacoma (City) / Department of Public Utilities (TPU) / Water Division (Tacoma Water) is soliciting bids to establish a contract for the re-roof of a 3.5 million gallon concrete reservoir. The Indian Hill Reservoir is located off Orcas Drive NE in Federal Way, Washington. The concrete roof of the reservoir's 3.5 million gallon belowground concrete tank is covered by a hot mop pea gravel coating installed in 1981. The hot mop pea gravel coating has exceeded its expected useful lifespan of 20 years and has deteriorated with multiple areas of no roof covering. Additionally, there are concerns that the hot mop pea gravel may leach metals or other compounds which could enter the tank via rainwater through cracks in the roof. The objective of this project is to analyze the existing hot mop pea gravel material and prepare a disposal plan for the material once removed; remove the existing roof coating in its entirety, repair any cracks or flaws identified in the reservoir roof once the coating has been removed; evaluate the existing reservoir vents based on reservoir flowrates and upgrade the vents, to meet AWWA standards; and to install a new high performance coating system on the roof. A Tamoseal/Tammscoat Base Coat/Finish Coat by Euclid Chemical Company coating system will be installed on the tank roof. This coating system was recently used by Tacoma Water as part of the successful Hood Street Reservoir Seismic Upgrades project. Also, initial evaluation of the tank indicates that current stormwater drainage patterns (i.e., sheet flow off the roof onto the surrounding ground) are adequate and drainage crickets are not necessary. Replacing the existing coating with a new high performance coating system will make these flow patterns more efficient and will decrease the potential for stormwater to pond on the reservoir roof. Overall, this project will repair any cracks in the reservoir roof, ensure the reservoir tank is sealed against and protected from rainwater intrusion, and bring the tank venting up to current standards.
