Whitson CM & CA Filtration Specialists design and install a 99,000 cf stormwater tank along a golf course in Palm Desert, CA. The construction of this system is less labor intensive than other modular tank systems which is a good thing, considering the triple digit temperatures that our crews worked in! Thank you, guys! Plus, […]
Capturing rain to replenish groundwater with Pavedrain

AquaSave to the rescue

National Groundwater Awareness Week (GWAW)

It is officially, “GROUNDWATER AWARENESS WEEK”, and the perfect time to talk about GEPS®: Ground Energy Passive System. GEPS® facilitates water-ground interaction akin to diffusion by passively distributing moisture throughout the soil volumetrically. In soils with low permeability, GEPS® promotes lateral moisture distribution between soil layers thus creating infiltration. GEPS will recharge our groundwater. Our […]
157,000 GALLONS of stormwater runoff
