Case Study Overview

Every 10 years the Newton Water Tower Tank requires internal inspection to identify if any maintenance work is required to keep the tank working as efficiently as possible. Upon inspection in 2024, the 264m³ water holding tank required extensive internal repair, followed by the re-lining of the tank walls.

Challenge

Contractor, Churchill Specialist Contracting Ltd, were tasked with carrying out the project, and they identified that specialist climate control equipment would be needed to ensure the project was completed on time.

Solution

Churchill Specialist Contracting Ltd contacted RVT Group, and our experienced consultants visited site to assess the challenges. Following the visit, we were able to provide a bespoke, effective drying out system for the project.

For the internal drying of the tank after the jet washing had been completed, we installed a CLIMEX® DD450 Desiccant Dehumidifier. With access restrictions, this equipment was placed on the roof of the tank via a crane. The unit had two duct runs going into the tank which fit through the restricted access point. One of duct runs extracted the moisture from the air in the tank, and then released it outside of the tank into the atmosphere. The second was forcing dry air back into the tank to create air circulation, speeding up the drying process. Unlike traditional dehumidifiers, this equipment is able to sit outside the work area, making it the most suitable solution for the logistical challenge of this project.

In support of this equipment, we also installed CLIMEX® 9KW Heaters within the tank. These heaters were small and lightweight enough to be passed through the access point and carried down the ladder safely. These fan heaters have a convenient built-in thermostat, helping to maintain an ambient temperature and draw out the moisture efficiently. With no requirement of fuel such as propane or diesel, this solution was the most suitable for inside a tank, which had little to no ventilation.

Following the implementation of RVT’s specialist solutions, the maintenance of the Newton Water Tower was successfully completed on time.
