Hauled Waste and the Environment


Hauled Waste Program

Manheim Area Water & Sewer Authority (MAWSA) Hauled Waste Program receives both domestic and non-domestic liquid hauled waste. All parties who wish to discharge liquid hauled waste to MAWSA must contact the  MAWSA Wastewater Treatment Plant at (717) 665-2737. All haulers are expected to abide by the Liquid Hauled Waste Policy and a manifest form is required for each discharge showing the name, address, and telephone number for the source of the wastewater.
The only location to discharge truck hauled wastes in Manheim  is at the Wastewater Treatment Plant discharge site, 135 Rettew Lane Manheim, Pa between the hours of 7:30 a.m. and 3:30 p.m. Monday through Friday, except for designated holidays.


Wastewater Sludge Processing

Processing and disposal of sludge is one of the most serious problem encountered in wastewater treatment in terms of environment, technology and budget. Sludge stabilization and associated cost represents a major part of the total cost in any wastewater treatment plant, it can account for 50-60% of the total expense of wastewater treatment plant operating budget. Sludge arising during treatment of municipal wastewaters presents a valuable source of organic matter, nitrogen, phosphorus, potassium and some trace elements. Wastewater Treatment Plants optimum solution for disposal of sludge is in agriculture.

Manheim Area Water & Sewer Authority is committed to the environment and uses land application for its sludge disposal. The Authority operates under PA DEP NPDES permit for disposal of Class "B "sludge. The Authority is in the process with its Wastewater Biological Nutrient Reduction project to install a Class "A" sludge processing system.


Final Treatment

Sewage treatment is a multi-stage process to renovate wastewater before it re-enters a body of water. The goal is to reduce or remove organic matter, solids, nutrients, disease-causing organisms and other pollutants from wastewater. Each receiving body of water has limits to the amount of pollutants it can receive without degradation. Manheim Area Water & Sewer Authority Wastewater Treatment Plant must hold a permit listing the allowable levels of BOD, suspended solids, coliform bacteria and other pollutants. The discharge permits are called NPDES permits which stands for the National Pollutant Discharge Elimination System. Final treatment focuses on removal of disease-causing organisms from wastewater. Treated wastewater is disinfected by adding chlorine. High levels of chlorine may be harmful to aquatic life in receiving streams. To protect the streams and aquatic life, the Authority adds a chlorine-neutralizing chemical to the treated wastewater before stream discharge.


Land Application

The Manheim Area Water & Sewer Authority Wastewater Treatment Plant process produce a sludge which has to be disposed of, the Authority process sludge allows land application which is more environmentally friendly than land fill disposal. Pennsylvania Department of Environmental Protection(DEP) regulates use of sewage sludge in agriculture to prevent harmful effects on soil, vegetation, animals and humans. In particular it sets maximum values of concentrations of heavy metals and bans the spreading of sewage sludge when the concentration of certain substances in the soil exceeds these values. Land application of raw or treated sewage sludge can reduce significantly the sludge disposal cost component of sewage treatment as well as providing a large part of the nitrogen and phosphorus requirements of many crops.
