Each plot owner was required to pay a fixed charge of Sh250,000 in addition to a registration fee of Sh1,000.
Titus Njari Ndei, 37, organized his fellow landowners in Kitengela to build a private sewer line after being arraigned in court a decade ago.
Currently, 818 Kitengela plot owners benefit from a 45-kilometer, two-foot-wide sewer system, which seemed difficult to build at first.
The sewer line, which has so far cost them Sh85 million, connects to the neighboring Athi River Export Processing Zone Water and Sewerage Project trunk sewer, which was built in the 1990s as pivotal support infrastructure for the Athi River Export Processing Zone by the National government at a cost of Sh700 million.
The county government took Mr Ndei, a locomotive engineer, and the other 22 plot owners to Kajiado law Court in 2013 for continual raw sewer issuing from their structures, which violated the public health legislation.
They were released on a bond of between Sh180,000 and Sh200,000 each until the outcome of the case, but Mr Ndei persuaded the court to let them come up with a long-term solution in two months.
"We(the accused) moved with speed to acquire the necessary authorisation from the Export Processing Zone (EPZA), Nema and other relevant authorities after registering ourselves as Kitengela EPZ Neighbouring community sewer project within the first two months to convince the court," Mr Ndei, project secretary general told Nation on Wednesday saying he is planning to rally his group to request for their bond refund now that the sewer line is in place.
Each plot owner was required to pay a fixed charge of Sh250,000 in addition to a registration fee of Sh1,000. Furthermore, a non-refundable charge payable to Epz in three categories ranging from Sh7,500 to Sh74,000.
The majority of Kajiado satellite towns, including Kajiado town, Ngong, Kiserian, and Ong'ata Rongai, lack sewer systems. All of the satellite towns have been raised to the status of municipalities.
