Full Refurbishing
Asher Industrial Maintenance provides expert refurbishing of all water towers. The full refurbishment of a water tower involves a comprehensive surface restoration and protective coating process to extend the structure’s service life and ensure long-term performance. All existing paint and coatings are completely removed through abrasive grit blasting to the national SSPC-SP 10 / NACE No. 2 standard (The official standard for Near-White Metal Blast Cleaning) This is a rigorous surface preparation process removing almost all rust, scale, and old paint, allowing only minimal, light staining (max 5%) for superior coating adhesion, achieved by slow, overlapping nozzle passes with abrasive media like steel grit, creating a textured "anchor profile" for the new finish. This process provides a clean, properly profiled surface necessary for optimal coating adhesion. Following thorough inspection and surface preparation, the tower is repainted with a high-performance, corrosion-resistant coating system designed to withstand harsh environmental conditions. The refurbishment also restores the tower’s structural integrity by tightening yokes and welding repairs. In many cases new manways are welded into place and railings are replaced or modified to meet current codes. Finally, all safety equipment is usually replaced with newer safer models for fall protection.

Blasting & Coating
Performing a high-quality grit blasting and recoating of an elevated water tank is critical to ensuring the structure’s long-term durability, safety, and reliability. Proper grit blasting completely removes failing coatings, corrosion, and contaminants, creating a clean, well-profiled surface that allows new coatings to bond effectively. When this preparation is done correctly, the recoating system can perform as designed, protecting the steel from moisture, chemicals, and environmental exposure that lead to premature deterioration. A quality job also helps prevent costly future repairs, reduces the risk of structural damage, and ensures continued compliance with regulatory and public safety standards, ultimately extending the service life of the water tank and safeguarding the community’s water infrastructure. Ascher Industrial Maintenance has expert crews that have years of experience blasting and coating tanks the right way, with extreme precision.

Pressure Washing
The process of pressure washing and silt removal in a potable water tank is a critical step to ensure water quality and public health before the tank is returned to service. After the tank is drained and properly ventilated, high-pressure washing is used to remove accumulated sediment, biofilm, and loose debris from the interior surfaces, including the floor, walls, and structural components. Collected silt and residue are carefully removed and disposed of in accordance with environmental and regulatory requirements. Once cleaning is complete, the tank is thoroughly rinsed and inspected to verify that all contaminants have been eliminated, ensuring the interior surfaces are clean and suitable for potable water before the tank is refilled and placed back into operation.
