We understand that the St. Tammany Parish Department of Utilities is planning to install two (2) new elevated water tanks, one at the St. Tammany Levee Board site and one at the Willow Wood WWTP site to supplement the existing Cross Gates Water System. While the exact site layouts and equipment setups have not been determined, the Department of Utilities is working with other regulatory agencies and an independent engineering consultant to evaluate the capacity and flow requirements of the new tanks. Based on the limited information available to date, we understand that consideration is being given to installing elevated tanks with maximum storage capacities ranging from 400,000 gallons to 1.0 million gallons. In order to maintain an adequate discharge pressure of at least 75 psi, the tanks will need to be elevated to a sufficient height to maintain at least 175 feet of water. The maximum height of the tanks is understood to be 190 feet. Based on conversations with Andre Monnot with Principal Engineering, the independent engineering consultant for the project, we understand that the unfactored working single pile loads are assumed to be between 160 and 220 kips. A new water well will also be installed at the Levee Board site which will have a minimum pumping capacity of 1,200 gallons per minute. In addition, both sites will include equipment slabs for lightly loaded ancillary structures such as control panels, generators and chlorine buildings. The geotechnical recommendations presented in this report are based on the available project information, water tower locations, and the subsurface materials described in this report. If any of the noted information is incorrect, please inform SE in writing so that we may amend the recommendations presented in this report, if appropriate and if desired by the client. SE will not be responsible for the implementation of its recommendations when it is not notified of changes in the project
