We recently completed the full internal relining of a GRP storage tank in Birmingham.
The water tanks internal gel coat had completely failed due to the occurrence of black spore osmosis.
This issue can usually be identified by small black spots which are visible on the water tanks internal surfaces.
These black spots are in fact a type of fungi which can be potentially harmful to health, especially if left untreated within a potable water storage tank.
Fortunately many reputable water treatment service providers employ Legionella risk assessors who specialise in being able to identify these issues when completing on site legionella risk assessments.
Once reported to a duty holder it’s their responsibility to ensure the appropriate remediation works are carried out to ensure the water tank remains compliant with ACoP L8 guidelines.
The issue above was reported to our client by their water hygiene provider who then contacted our team to help assist in providing the most effective solution.
Our first solution involved the full water tank replacement of the non-compliant cold water storage tank.
Our second more sustainable and cost-effective solution involved the full internal tank relining of the existing storage tank.
In this case our client decided to proceed with a full water tank reline.
This option proved to be significantly more cost effective than carrying out a full water tank replacement while also ensuring minimal disruption was caused to the sites water system.
Our tank relining solution also allowed for the water tank cleaning and disinfection to be completed prior to placing the system back online.
