Recycling project supplements farm water

Ag Alert – Having received little to no water from the federal Central Valley Project in recent drought years, farmers in a western Stanislaus County irrigation district have partnered with cities to purchase tertiary-treated recycled water, to help secure a more certain water supply. Farmers within the Patterson-based Del Puerto Water District say its water contract with the federal Read More…
