Boresaver EZ-ECO

BoreSaver EZ-ECO is a very safe rehabilitation product chemical that dissolves carbonates, manganese and iron oxide deposits in groundwater bores, wells, pumps and pipes.

  • Safer to transport

  • Non poisonous

  • Fully Biodegradable

  • Safer for workers

  • Along with Ultra C and Multikleen, approved for use in potable water wells NSF and Department for Health WA.

  • Effective and efficient


Through various chemical and bacterial processes, mineral deposits can cause clogging of groundwater screens, gravel packs, pumps and pipes.  To remove the clogging, BoreSaver EZ-ECO is added to the target treatment zone directly from the container and then agitated using standard well rehabilitation methods. This loosens and dissolves the clogging that can then be removed by bailing, airlifting or pumping.


BoreSaver EZ-ECO and the resulting treatment solution is non-toxic. Being an acidic cleaner, a pH test is a good indicator as to whether the system has been sufficiently purged.

Keys to successful product use:

  • Use the recommended amount of product for the situation.

  • Get the product to the area that needs it i.e., wells with more than 50m of water depth it may be useful to use a tremmie to get product directly into the screens.

  • Agitate the treatment solution thoroughly in the target zone.

  • Leave in place for 12 to 24 hours

  • Ensure all wastewater is disposed of in accordance with Environment Agency protocols.


Applying the Product

BoreSaver EZ-ECO is supplied ready to use. In wells with up to 50 m of water depth the solution can simply be tipped into the top of the casing. Subsequent surging, cycling, brushing etc of the well will do a good job of mixing the product into the target zones.

If the water depth (NOT the depth to water otherwise know as the static water level) is greater than 50m, we recommend using a tremmie system to place the product in the target zones. When we refer to a tremmie, we are describing a reel of pipe or hose with a pump attached that can place liquids to a variety of depths in the well.

Where the pump is to be left in place and a cycling method of treatment used, simply add the BoreSaver EZ-ECO and run the pump. This will efficiently clean the pump, rising main and upper sections of the casing but not have any significant impact below the pump intake level.

How Much To Use?

Minimum dose rate is 20% by volume of BoreSaver EZ-ECO to the water volume in areas to be treated. 
Maximum dose rate is 40% by volume of BoreSaver EZ-ECO to the water volume in areas to be treated.

Mechanical Surging

Reversed flow through the screen into the formation can be accomplished through the use of mechanical devices such as surge block or surge plunger. 

Air Assisted Development

Airlift pumping forces compressed air through an air line to the bottom of the well. As the mass of air bubbles rise, they create a surging effect that carries water and fines out of the well.  

Simple Pump Cycling Method

This method leaves the pump in the hole and directs the flow back down the well. Providing more of a focus on cleaning the pump, this method is most often used on wells that are not over clogged or where pump removal is not feasible or for economical.

On Site Disposal of Purge Water

Purge waters contain the minerals dissolved into solution (the original “problem source”), carbon dioxide and some amount of residual acidity. With BoreSaver EZ-ECO residual acidity will be minimal or nonexistent. Wastewater from the purge should be disposed of in accordance with Environment Agency protocols.
Contain the first two well volumes of the purge water onsite in a holding pit or tank for pH correction.
Adding sodium carbonate, sodium bicarbonate or sodium hydroxide until pH 7 is reached will correct the pH almost instantly.
