How to Remove Sand from Well Water at 55 GPM


We are a small community water system. Three wells to filters, chlorine injection before storage tanks. TCEQ defines our shallow wells as ground water under the influence of surface water. Wells are approx 45 ft deep. Two of the wells actually meet filter requirements before filtering. The third well (after about 3 years of dry weather) has excessive sand. It will flow about 55 gpm. We are seeking your opinion of a filter method for the sandy well before intersecting the common supply line (the three wells flow into a common flow line before the filter system and chlorination). These wells only run on demand, when the tanks are low. We normally only run on two wells. Presently we are not using the sandy well, but would like to be able run with one of the other wells should one well go down. What do you suggest?

Dear Nolan,

For this application, we recommend the Lakos sand separator with purge kit. The separator will remove any particles that will settle out in a jar or beaker within 3 minutes. For a flow of 55 gpm, we recommend the 1.5" model.

Lakos centrifigal separators have no screens, solid baffles, or moving parts. No maintenance is required other than periodic purging of the unwanted solids by opening up the bottom ball valve.
Installing a purge kit to automatically purge the separator, will require even less maintenance. If you want to add a pricey but very reliable and heavy-duty purge kit, we recommend the AutoMBV Motorized Ball Valve.
