EFFECT OF DOMESTIC WASTEWATER ON SOIL PROPERTIES AROUND TREATMENT PLANT

Abstract

The paper investigated the impact of domestic wastewater on soil properties surrounding a treatment plant. One of the primary concerns addressed in the study is the reuse of wastewater for various purposes such as artificial recharge of aquifers, drinking water, and agricultural irrigation. Utilizing treated wastewater as a reliable water source for urban areas and population centers has become a common practice worldwide. In this context, employing methods based on the utilization of low-quality irrigation water, such as wastewater, presents a practical and convenient solution. Wastewater can serve as a rich source of minerals and organic matter, contributing to soil fertility. In the present study, the effects of wastewater from the refined sewage system in Sokoto on soil chemical properties were assessed through depth measurements. Soil samples were collected from depths of 0-30 centimeters and 30-60 centimeters and analyzed using a randomized complete block design with three replications. The results indicated a decrease in acidity, salinity, phosphorus, nitrogen, and heavy metal concentrations in the soil irrigated with wastewater compared to soil irrigated with well water.
