LGC Water Treatment Plant

LGC Water Treatment Plant

Location: Schertz and Seguin, TX

Rapid growth within the cities of Schertz and Seguin, Texas, increased water demands and strained water supply capabilities. The Cities formed a Local Government Corporation (LGC) so they could function as a single entity.  After reviewing treatment designs and options, the engineers and the LGC chose to design the 10 MGD plant filtration system around Tonka Water’s OptaCell™ horizontal pressure filters and PLC control system.

The treatment processes consists of pressure aeration and chemical feed for oxidation and disinfection, six OptaCell™ pressure filters with three cells each, storage and high service pumps. The filter design includes a common underdrain to the three cells, a dual media bed of manganese greensand, anthracite and a unique backwash trough. The plant can treat up to a peak flow of 17 MGD of raw water.

The raw water analysis summarized below reflects moderate concentrations of iron and manganese existing in the water. The treatment process has been highly efficient in delivering high quality water as indicated below.
