## How Sand Filtration Systems Improve Water Quality
				
				
		
				
				
									Stormwater sand filter systems, or filtration basins, have been used for decades to treat stormwater runoff and [improve water quality](https://aqualisco.com/service/water-quality-testing/). Sand filter applications can be presented on the surface, below the surface, or within a cartridge configuration.  With coarse sand often used as a primary filter media, other filter system medias can be selected with design developed to control rates of flows released and special medias that target contaminants.

## How Sand Filters Work for Water Treatment
				
				
				
				
									Sand filter systems temporarily store stormwater runoff to filter and remove pollutants before they reach natural water sources, such as creeks, streams and rivers. Stormwater is filtered through a natural, or an engineered filter media, and systems are commonly designed with two chambers. 

The first is a sediment chamber, or forebay, where larger particles deposit before the runoff water is filtered in a filtration bed of sand where fine particles are removed. Afterward, the filtered water is typically collected in an underdrain and then conveyed to the storm drainage system. 

								
				
				
		
				
				
					
### Identifying and Addressing Clogging in Sand Filters
				
				
				
				
									Sand filters should be inspected regularly as they are subject to clogging. Clogged sand filters no longer provide water quality benefits and require media replacement to return to function. 

Sand filter media can readily be reconditioned and supplemented to promote improved efficiency and to resume intended performance.

### [Why Stormwater Requires Treatment](https://aqualisco.com/why-stormwater-requires-treatment/)
				
				
				
				
									As cities and towns develop, more impervious surfaces are created, preventing stormwater from absorbing into the earth.

## The Benefits of Stormwater Sand Filters
				
				
				
				
									Stormwater sand filters provide water protection, water conservation, and stormwater quality benefits. Some of the benefits of a sand filter system include:  

- An efficient and effective pollutant and contaminant removal through pretreatment and treatment chambers 
- Reduction of water runoff and stormwater volume control from development sites 
- Groundwater recharge 
- Configured into any layout required with little required surface land 
- Fewer site restrictions make them suitable for small residential and commercial areas 

								
				
				
				
					
### Stormwater Sand Filter Installation and Maintenance
				
				
				
				
									As a [stormwater management company](https://aqualisco.com/service/stormwater-management/), AQUALIS specializes in the construction and maintenance of sand filter systems. Once the construction is complete, an AQUALIS representative will establish a plan to properly maintain the sand filter system to ensure that future storm water samples are collected, reporting is conducted and other documentation is done correctly.  

AQUALIS provides system maintenance to help you properly maintain a sand filter [stormwater management system](https://aqualisco.com/service/stormwater-management/stormwater-systems/). To ensure stormwater sand filters provide reliable rates of pollutant removal, a regularly scheduled maintenance plan is necessary.

 We inspect pretreatment devices, structural components, infiltration systems and sand filter systems regularly to help you continuously implement an effective stormwater program. Using our certified stormwater best management practices inspection, our [specialized maintenance professional](https://aqualisco.com/service/stormwater-management/stormwater-maintenance/) will manage and submit all the necessary inspections and required annual reports for you.

## Best Practices for Sand Filter Operation and Management
				
				
				
				
									AQUALIS provides sand filter development, implementation and restoration beginning with a thorough site assessment to analyze existing conditions. Utilizing hydrologic calculations, our [Engineering Services Division](https://aqualisco.com/service/sustainable-water-engineering/) can best understand the water flow and movement before and after implementation.

 Working directly with local regulators, AQUALIS will ensure your project complies with local and federal regulations while securing funding. Following best practices, regular inspections and testing and developing a long-term Operations and maintenance agreement ensures your sand filter project properly manages stormwater for years to come.
