For 25 years, ALCO Engineering, a division of Thielsch Engineering, has been providing services in the water and wastewater industries. These services include supplying equipment/parts and technical support for controls and instruments.

On January 1, 1995, ALCO acquired the worldwide BIF® replacement parts and support service business. As of that date, ALCO Engineering became the exclusive, authorized manufacturer and distributor of BIF parts and services.

ALCO is also an international supplier of recording charts and marking systems for both foreign and domestic instrument manufacturers. We maintain an extensive in-house inventory of disposable pens and provide prompt delivery of chart orders.
