avenues to improved operational efficiency in pumping

Q: Are there more avenues to improve operational efficiency in relation to water pumping? A: While further opportunities are limited for agricultural or golf course type of customers, water districts have other potential areas where operational efficiencies can be improved. One of the biggest areas of improvement is in water treatment plants. Traditional water treatments plants use energy intensive mechanical aeration plants in aerobic digesters for water treatment. Newer plants make use of VFD controlled blowers used in conjunction with dissolved oxygen sensors. On a per million gallons per day (MGD) basis, blowers use much less power and hence energy when compared to mechanical aerators.
