Design and maintenance of facilities and monitoring stations.

Preliminary treatment and flow equalization facilities or monitoring stations, if provided for any wastewater, shall be constructed and maintained continuously clean, safe, accessible, and continuously operational by the owner at his expense. Where an industrial user has such treatment, equalization, or monitoring facilities at the time this chapter is enacted, the Chief Plant Operator and/or Superintendent of Sewers may approve or disapprove the adequacy of such facilities. Where the Chief Plant Operator and/or Superintendent of Sewers disapproves of such facilities and construction of new or upgraded facilities for treatment, equalization, or monitoring are required, plans and specifications for such facilities shall be prepared by a licensed professional engineer and submitted to the Chief Plant Operator and/or Superintendent of Sewers.

Construction of new or upgraded facilities shall not commence until written approval of the Chief Plant Operator and/or Superintendent of Sewers has been obtained. All devices used to measure wastewater flow and quality shall be calibrated as required to maintain their accuracy.
