Project Updates

Chemususu Dam

















The dam is located in Baringo County, Koibatek District and has a capacity of 15 million cubic meters or 15 billion litres. Chemususu Dam discharges 35,000 cubic metres or 35 million litres of water per day. It was designed to serve at least 50% of Baringo County population which includes towns and various institutions within the County.


Soin-Koru Dam


The Soin-Koru Dam Development project is proposed to be located on the Nyando River in the vicinity of Muhoroni in the Western part of Kenya. It shall be 60km from Kisumu City and 5km upstream of Muhoroni town. The Dam will be located in Kisumu and Kericho counties.


Siyoi - Muruny Dam

















The proposed Muruny Dam is located near Kapsait Primary School at Murkokoi Center which is approximately 43km from Kapenguria Town. The site location is covered on SK Map 75/4 Cherangany at GPS coordinates 36 N 0761064 and UTM 0129350, elevation 2690 masl at the riverbed. The project area lies within the Rift Valley Drainage Basin. River Muruny emanates from Cherangany Hills and flows in a North Eastern direction before finally draining into Lake Turkana.


Kiserian Dam









Kiserian dam is located along Kiserian River about 2kms from Kiserian Township and will supply water to Kiserian, Ongata Rongai and parts of Ngong’ townships. The present (2010) total population of the area is about 124,000 people with a water demand of 8,450m3   per day. The 18m high dam will store 1.22Mm3 of water and supply 15,700m3  per day of water to the townships which will meet the future (2020) water demand.


Maruba Dam

















In June 2010, NWCPC finalized rehabilitation of Maruba dam by raising the height of the embankment wall and spillway by 6 m. This increased the dam’s storage capacity from 0.60 Million m3 to 2.45 Million m3.  Increase in storage volume has ensured increase in water supply to Machakos Town and its environs from 2,050 m3/day to 8,700m3/day.

The New ISO Standard

ISO 9001:2015 is an International Standard dedicated to Quality Management Systems (QMS). It outlines a framework for improving quality and set procedures through which an organization carries out its operations in a consistent manner to meet the requirements and expectations of its stakeholders effectively and efficiently. The new standards were published in 2015, giving institutions a three year transition period to upgrade their ISO 9001:2008 certification to ISO 9001:2015. In view of this, National Water Harvesting and storage authority (NWHSA) has started a road map towards certification for the the  new standard; ISO 9001:2015.

The Authority through the Kenya Bureau of Standards (KEBS) in conjunction with the National Quality Institute (NQI)   has already trained several staff who will take lead  in the implementation of the new standard, on the Quality Management System (QMS) implementation Course.

Acting Chief Executive Officer CS. Sharon Obonyo thanks KEBS for their support and urges all staff to embrace the new standard saying this will help promote best practices in the Authority hence, ensure efficient operations such as prudent financial management, improvement in turnaround time and service delivery. CS. Obonyo graced the staff trainings and reiterated management’s commitment in the implementation of the new standard.


The four day course sought to help participants understand the basic concepts of quality management, the requirements of ISO 9001:2015 standard and acquire and be able to apply knowledge and skills to implement the QMS based on the new standard.

Dennis Osoro and Nancy Rotich who are members of the ISO implementation Committee helped us to unbundle the new standard and gave us highlights of the same.

 Difference between the old and the new ISO 9001:2015 standard

Quality Manual: it is no longer a title specific requirement. The new requirement for “Documented information” gives greater freedom on how this is implemented.

Management Representative: This was a tittle used in the ISO 9001:2008 standard. The new standard requires that management appoints a team leader who will oversee its implementation and will be called a Quality Management Champion.

Preventive Action: The change from “preventive action” to “risk and opportunity” is an example of a where management is required to adopt risk-based thinking so as to prevent potential risks and capitalize on new opportunities.

Quality management System and its processes: This approach requires that an organization shall establish, implement, maintain and continually improve a QMS while managing inter-related processes.

The new ISO Standard

 Risk based thinking: As already noted, the Authority will be required to do a risk assessment then come up with risk mitigation measures.

Interested Parties: this has been added to clause 4.2 but with the precaution that it is “relevant interested parties”. To be relevant, the interested party must have some actual or potential impact on the quality of the goods and services.

Control of changes: this is aimed at ensuring that review or any changes in production or service provision is necessary to ensure continued conformity with requirements.

Leadership: top management shall demonstrate leadership and commitment to QMS and offer strategic direction.

Achieving the ISO 9001:2015 standard is not about establishing a set of procedures that are complicated and difficult to manage. The aim is to provide a workable management system that is suitable for the institution. With the right support and the knowledge of the employees, the institution will establish a system that will improve all areas of its operations. Most importantly, implementing an effective and robust ISO 9001:2015 Quality Management System (QMS) will help the institution to focus on the important areas in regard to its mandate and improve efficiency.

The Authority is in the right track in aligning its processes towards the ISO 9001:2015. After training of the implementors, QMS internal auditors from the Authority will also be trained after which all staff will be sensitized before implementation of the new standard. It is after meeting all these requirements that the Authority will be certified.
