| DAVYHULME ANAEROBIC DIGESTION FACILITY

Black & Veatch was contracted as part of the Davyhulme scheme to provide two new 2.4MWe CHP engines and relocate three existing CHP engines, providing a combined 12MWe of electrical generating capacity.

12MW ANAEROBIC DIGESTION PLANT UPGRADE AND NEW PRE-TREATMENT PLANT Davyhulme AD Black & Veatch was appointed as an EPC contractor for the upgrade of one of the largest waste water treatment works (WWTW) in the UK at Manchester. Our scope of work doubled the sludge treatment capacity of the existing facility to 91,000 tDS/yr. The process produces biogas that is used in a CHP facility consisting of five 2.4 MWe biogas fired gas engines with steam heat recovery and boilers generating 26 t/h of steam. The scope included:

� 4 new Thermal Hydrolysis Streams totalling 20 individual reactors;

� New imported cake facility;

� Modifications to existing AD tanks;

� New biogas holders and biogas clean-up plant;

� New steam plant;

� New CHP plant (12MWe);

� New digested sludge storage.

� Existing HV electrical infrastructure modifications. Our market leading capabilities resulted in this project receiving the following awards and was described as:

� IChemE award for Innovation and Excellence in the Energy category – 2013;

� British Construction Industry (BCI) Award - UK’s Major Civil Engineering Project of the Year 2014.

2.4MW ADVANCED DIGESTION PROCESS PLANT IMPROVEMENTS & ADDITIONS Colchester & Pyewipe AD Black & Veatch improved Anglian Water’s existing sludge treatment centres at Colchester and Pyewipe Sludge Recycle Centres in separate EPC contracts. Our refurbishment works for Colchester allowed treatment capacity to increase to 40tDS /d, whereas Pyewipe’s treatment capacity was increased to 48tDS /d.

Both AD sites use an advanced digestion process incorporating heat, pasteurisation and hydrolysis, (HpH). The biogas produced is utilised by a CHP facility to produce 2.4MWe output and steam boilers, which utilise the CHPs’ waste heat to raise steam for the HpH (hydrolysis) plant (15,000 tDS/y Colchester and 17,500 tDS/y Pyewipe) and mesophilic digesters. Our scope of works included:

� New imported cake facility;

� New liquid reception facility;

� New HpH (Heating, pasteurisation and biological-hydrolysis) pre-treatment stage;

� New AD tanks and biogas holders and biogas clean up;

� CHP plant (2.4MWe);

� Digested sludge storage;

� Existing HV electrical infrastructure modifications;

� New odour control plant.

The design was done using 3D modelling and intelligent P&IDs, allowing the transfer of information at the end of the project to the Client’s Asset Management Database.

Health and safety considerations were paramount as a high pressure grid gas main runs adjacent to the digester construction area, resulting in exclusion zones for construction and operations. To mitigate emission impacts and improve Health & Safety (H&S) on and around the digester and HpH tanks, the relief valve configuration was arranged to emit gasses away from operators, but such as to minimise the zoned area.

A similar refurbishment contract (with similar scope to the above listing) was executed at Pyewipe under a separate EPC contract with Anglian Water.

1.5MW ADVANCED DIGESTION PRE-TREATMENT PROCESS PLANT IMPROVEMENTS & ADDITIONS Whitlingham & Cotton Valley AD Black & Veatch was appointed as a design and build contractor by Anglian Water for the provision of advanced digestion treatment facilities using a thermal hydrolysis process upstream of the anaerobic digester tanks. The chosen process, thermal hydrolysis using Cambi technology, delivers significantly reduced volumes of enhanced treated, high quality sludge whilst maximising the biogas yield for energy generation.

After the thermal hydrolysis process, the sludge undergoes conventional mesophilic anaerobic digestion in two digesters. Biogas from the digesters is fed to a CHP unit for electricity generation. Excess biogas is used to supplement the fuel requirement of the steam boiler.

Both projects, Whitlingham and Cotton Valley, comprised an upgrade of the existing sludge treatment plant to treat c. 20,000 tDS /yr and involved the installation of c. 1.5MWe of CHP plant. The upgrade works at both sites included:

� New liquid reception facility;

� New sludge screening, blending and mixing facility;

� New Thermal Hydrolysis Plant (THP);

� Modifications to existing AD tanks;

� New steam boiler;

� New CHP plant (1.5 & 1.75MWe);

� New waste heat recovery plant;

� New biogas clean up;

� Existing HV electrical infrastructure modifications.

3MW ANAEROBIC DIGESTER REFURBISHMENT Mogden AD This high profile EPC project boosted the capacity of the UK’s third largest sewerage works by 50%. Black & Veatch were awarded the EPC contract to upgrade Mogden WWTW with digester related works as part of the overall contract.

As part of the works, the sludge stream capacity was increased by extending the sludge pasteurisation plant and incorporating significant odour control facilities. The project scope included safety, management, design, installation and commissioning of:

� New digester feed pumps; � New digesters roof replacement; � New gas mixing for each refurbished digester; � New 3MW dual fuel in-line boiler system; � New Motor Control Centre (MCC); � New substation; � New SCADA system.

On completion, more than 40% of the energy required to treat storm and wastewater was generated onsite from renewable biogas.

As part of the safety regime, more than 100,000 man hours were worked on site without a RIDDOR incident or minor injury. This was achieved by:

� Active involvement of the workforce in safety issues;

� Monitoring safety behaviour and acting on trends;

� Making safety the number one priority all of the time.

ROOFTOP SOLAR PV Brightergy Inc, Kansas City, USA Black & Veatch formed a strategic alliance with Brightergy, Inc. in October 2013 to develop $100 million in solar energy projects during a three-year period. Part of this alliance includes Black & Veatch serving as EPC contractor for rooftop solar PV systems on commercial and industrial clients’ property in and near the Kansas City Metro area, as well as in other parts of the United States.

Brightergy is serving as the project developer and providing sales, marketing and financing. Black & Veatch delivers EPC services as well as consulting support.

The alliance targets commercial-scale PV solar rooftop projects ranging from 25kW-2 MW.

SOLAR POWER PLANT PV Arizona, USA Black & Veatch provided the EPC solution for a 32 MW (50 MWdc) Utility Scale Solar Power Plant. Now completed, the project provides the energy needs of 8,000 homes and businesses. During construction, Black & Veatch utilised “lean construction” principles to improve the productivity of tracker and PV module installation whilst also completing the project within budget and schedule.

HYDROTURBINE PORTFOLIO 5 Site Development (100-700kW) As a Design and Build Contractor (DBC), B&V were appointed by Scottish Water (SW) to develop, optimise and deliver 5 hydro-turbine schemes across the Scottish Water asset base. Following a financial and technical appraisal of 8 potential hydro turbine installations, the individual schemes were ranked according to their financial and technical performance and in terms of how much they could contribute to towards SW’s renewable energy generation target.

On the basis of their technical and financial ranking, B&V were then tasked with the ‘design and build’ delivery of 5 of the 8 schemes assessed at feasibility stage. The schemes taken to construction include:

Delivery has been a multi-disciplined affair with planning, resource and impact modelling, design, specialist hydro technical expertise, construction expertise, etc. all playing their part in the project development process.

Each site presented individual technical difficulties, with installations located in: raw water distribution, reservoir outlets, inlets to waste treatment works and within raw water pumping stations. Some of the other technical challenges that have had to be overcome include: obtaining accurate flow and head data, complex modelling of catchments for availability prediction, best turbine selection, surge analysis, integration into existing systems (constraints of space, access, remote locations, lifting, blending of differing waters, control systems, communication systems) and grid connection. The 5 schemes were completed in late 2014 with works completed on schedule and on budget.
