The importance of stormwater management cannot be understated. It involves a number of treatment processes that help reduce runoff pollution, prevent erosion and improve water quality. Nevertheless, for one to manage and treat runoff water effectively, you need to install stormwater filters in your storm drains.
What are stormwater filters?
Storm filters are filtration devices that trap particulates and eradicate hydrocarbons, metals and suspended solids from collecting in water runoff. They work by capturing and holding runoff water temporarily for treatment, before passing the filtered water in an under-drain and then back to the drainage system.
The essence of installing stormwater filters is to ensure that the water that goes to replenish our aquifers and surrounding water bodies is of high quality. For this reason, it is important to clean and replace your stormwater filters regularly.
When should you replace your stormwater filter?
The recommended lifespan of a stormwater filter is about three years. With this in mind, it is imperative to change the filter after this period elapses, regardless of its state.
Here are additional indicative signs that it is time to change your stormwater filter:
Hazardous material discharge – If you notice any hazardous materials such as oil and aerosols floating on the surface of the water, then you should replace the filter immediately. A good filter should be able to absorb hazardous waste, hence making sure the water is safe for use.
Sediment buildup – The function of the filter is to separate sediments from the runoff. However, over time, sediments are likely to accumulate, hence rendering the filter ineffective. When this occurs, it is advisable to replace the filter as soon as possible.
Debris buildup – The buildup of dirt and debris on the walls of the filter is another telltale sign that it requires thorough cleaning. However, cleaning the filter is just a short-term solution, and you may have to replace the entire filter for enhanced filtration.
Visible froth – A visible line of froth or scum around the drain is a sign of stagnant water, meaning that the filters are blocked and they require thorough cleaning or replacement.
Standing water – Under normal circumstances, the storm drains should absorb water within 24 hours after a heavy downpour. However, if there’s standing water around the drains after this period has elapsed, you need to replace your filters.
The benefits of replacing your stormwater filters
Storm filters play a vital role in the filtration of runoff water. Without these devices, the quality of water absorbed may possibly be questionable. With this in mind, it is important to clean or replace your filters regularly to achieve a superior filtration process.
Below are the benefits of replacing your old stormwater filters.
Efficient treatment -Stormwater filters provide efficient treatment options, by eradicating contaminants that affect water quality. Filters also ensure that only clean water passes through the drain back into the underdrains and surrounding water bodies. However, if left unattended, the filter will lose its efficiency, thus allowing contaminants to pass through. When this occurs, it is imperative to replace the filter.
Ability to target specific pollutants – One of the most important benefits of stormwater filters is their ability to target specific contaminants. If your filter can only capture one type of pollutant, it is advisable to replace it with one that is capable of filtering all types of contaminants.
Design flexibility – Various storm filters are capable of performing different functions. If your current filter is not delivering the desired results, you may consult a stormwater management company to help in determining the best filter that suit your unique requirements.
